How accurate is this calculator vs. a real-world TCO?

Methodologically it’s the same approach AAA, Edmunds, and Consumer Reports use — purchase price + fuel + maintenance + insurance − resale, summed over 5 years. What it simplifies: state-specific sales tax + registration fees (varies $300-$2,500/yr; not modeled, applies similarly to both vehicles so cancels out in the gap), opportunity cost of capital tied up in the down payment (excluded — most TCO frameworks treat purchase as sunk), charging-equipment cost (a Level-2 charger is $500-$1,500 + $300-$1,000 install — meaningful for low-mileage drivers, negligible for high-mileage; not in calc). Use this as the strategic gut-check; real-world variance vs the calc number runs ±$3-5K depending on local fuel + insurance pricing and your driving pattern.

Why does electricity rate dominate the result so heavily?

Because EV fuel cost scales linearly with the rate, and 5 years of fuel is the second-largest line item after purchase. At the default 13K mi/yr × 3.0 mi/kWh × 5 yrs = ~22K kWh of charging. At $0.13/kWh that’s $2,800; at $0.30/kWh it’s $6,500 — a $3,700 swing on a single input. The calculator surfaces the exact ‘electricity flip-point’ (the rate at which EV stops winning) in the result panel. For most users with home Level-2 charging at $0.10-0.18/kWh, EV wins comfortably; for users who charge mostly at public DC fast chargers at $0.30-0.45/kWh, the comparison flips and ICE often becomes the better economics.

What about supercharger / public DC fast-charging cost?

If you charge mostly at superchargers (Tesla Supercharger ~$0.28/kWh on standard plan, $0.34/kWh peak; EVgo ~$0.36/kWh; Electrify America ~$0.43/kWh), use the public-charging rate as your input — not the home-charging rate. The calculator’s flip-point usually lands around $0.25-0.35/kWh for the default inputs, meaning supercharger-only operation often makes the EV TCO close to or worse than ICE. Realistic mixed strategy for most owners: 80-90% home-charging at $0.13/kWh + 10-20% supercharger at $0.30/kWh → blended ~$0.16/kWh, still comfortably below most flip-points.

Does the EV federal tax credit really apply in 2026?

No — not for vehicles acquired in 2026. The federal Section 30D new-clean-vehicle credit ($7,500) and the used-EV credit ($4,000) expired Sept 30 2025 under the One Big Beautiful Bill (Public Law 119-21). The only exception is a written binding contract with a payment made on or before Sept 30 2025 (you can then claim it when you take delivery). For any 2026 purchase there is no federal EV credit, so this calculator defaults the field to $0. Some states and utilities still run their own EV rebates — enter that amount in the credit field if you qualify (check the DSIRE database).

Why use 3.0 mi/kWh and 28 MPG as the efficiency defaults?

3.0 mi/kWh is the mid-tier blended EV efficiency: Tesla Model 3 long-range ~4.2 mi/kWh, Model Y ~3.8, ID.4 ~3.3, Bolt ~3.5, Mustang Mach-E ~3.0, F-150 Lightning ~2.0, Rivian R1S ~2.2. Use 4.0+ if you’re looking at a Model 3 or compact-EV; use 2.0-2.5 if you’re buying an electric truck. 28 MPG matches mid-size sedan baseline (Camry 32 highway / 27 combined, Accord 30 combined, Sonata 30 combined) — adjust upward for compacts (Civic 36) and downward for trucks (F-150 22, Silverado 19). Both efficiency assumptions are surfaced in the result-detail tooltips so you can see exactly what’s baked in.

Should I include the cost of a home Level-2 charger?

If you don’t already have one, yes — it’s a real $1,500-2,500 cost most TCO frameworks don’t model. Hardware: $400-800 for the charger (ChargePoint, Wallbox, Tesla Wall Connector); installation: $300-1,500 depending on panel-amp availability + run length to garage. Federal tax credit: 30% of cost up to $1,000 (Section 30C, available through 2032). Some utilities + state programs add $250-1,000 rebate. To model this in the calculator, add the net cost (hardware + install − credits − rebates) to the EV price input — it represents real upfront capital required to make EV economics work.

What about battery-replacement risk at year 8-10?

Modern EV battery warranties: 8 yrs / 100K miles (federal minimum), 10 yrs / 150K (Tesla, Hyundai), some up to 12 yrs unlimited (Volkswagen ID series). Replacement cost out of warranty: $5,000-15,000 for compact EVs, $15,000-30,000 for trucks/SUVs. Real-world data (Recurrent Auto, Tesla 2023 impact report): < 1% of EVs need full battery replacement before year 10; the typical degradation pattern is 8-12% capacity loss at year 8 (Tesla data) — annoying but not requiring replacement. The 5-yr TCO calculator deliberately excludes battery-replacement risk since most owners stay within warranty over the horizon. For 8-10 yr ownership, add $50-100/mo to your EV maintenance line as a battery-reserve fund and re-run.

How does the resale-value delta work?

Modern EVs (post-2020 Tesla, Rivian, Lucid, Mustang Mach-E) retain 45-55% of MSRP at 5 yrs — comparable to top mid-size ICE brands (Toyota, Honda, Subaru retain 50-60%; Ford / GM retain 35-45%). Older EVs (early Nissan Leaf, Chevy Bolt 2017-2019) retained 30-40% at 5 yrs because battery-degradation concerns suppressed used demand. The calculator’s baseline is 45% (parity with mid-size ICE). Set resale delta positive (e.g., +5 or +10) if you’re buying a Tesla / Rivian with strong residual data; negative (-10 to -20) if you’re buying a less-popular EV brand (Polestar, Lucid Gravity, BMW iX). KBB and Edmunds publish model-specific 5-yr residuals; check yours and adjust.

What if I plan to keep the car 10 years instead of 5?

Run the calc as-is (5-yr horizon) to see year-5 TCO + resale, then mentally project year 5-10. Years 6-10 favor EV more strongly: continued fuel-cost compounding (especially if gas appreciates 4-5%/yr), maintenance gap widens (ICE engine + transmission service costs ramp), insurance gap narrows (EV repair-cost variance compresses with parts-availability). However, year 8-10 introduces battery-replacement risk for older EVs (less of a concern post-2022 models). Rule of thumb: if 5-yr TCO favors EV by > $5K, 10-yr TCO favors EV by 1.8-2.2× that gap. If 5-yr is a coin-flip, 10-yr usually tips clearly to EV unless you’re a very low-mileage driver.

Why doesn’t the calculator include sales tax / registration?

Because they apply to both vehicles roughly proportionally (sales tax % is the same; registration is annual and similar for cars in the same weight class), so they cancel out in the EV-vs-ICE GAP — which is what you actually need to make the decision. State exceptions where this matters: NJ + WA + many EU jurisdictions exempt EVs from sales tax (a $1,500-3,500 advantage for EVs); some states levy EV-specific annual registration fees ($50-225/yr extra) to compensate for foregone gas-tax revenue. To model these state-specific factors, adjust the EV price input downward by the sales-tax exemption amount, or add the EV-specific reg fee × 5 yrs to the EV maintenance line.

What’s the carbon-footprint comparison?

Using EIA 2024 grid avg ~0.85 lb CO₂/kWh and 8.89 kg CO₂/gal of gasoline: at 13K mi/yr, EV emits ~3.7 t CO₂/yr (charged on US-avg grid mix); ICE emits ~4.6 t CO₂/yr. Over 5 yrs: EV ~18.5 t vs ICE ~23 t — EV ~20% lower lifetime CO₂ on US grid mix. The gap is much larger on cleaner grids (CA / WA / NY ~50% renewable → EV ~70% lower), and inverts on coal-heavy grids (KY / WY / WV ~20-30% lower or worse vs ICE — sometimes a wash). Battery-production CO₂ (~5-8 t for a typical EV battery) is recovered within 1-2 years of operation on an avg-grid; ~6 mo on a clean grid. Carbon-footprint detail not in the headline output but worth running through the Carbon Footprint Calculator (L.5.6 — coming).

What about maintenance differences I’m not thinking of?

EV maintenance items vs ICE: BOTH need tires (similar wear), cabin air filter (annual), 12V auxiliary battery (every 4-6 yrs), wiper blades, washer fluid, coolant flush at 100K miles. EV-specific: brake fluid every 2-3 yrs (same as ICE but less critical due to regen reducing brake-system stress), high-voltage battery coolant flush at 100K miles. ICE-only items eliminated: engine oil + filter (every 5-10K miles, $50-100 each), spark plugs (every 30-100K miles, $200-400), transmission fluid + filter (every 60-100K miles, $200-500), timing belt (every 60-90K miles, $400-1,000), exhaust system (every 80-150K miles, $300-800 if needed). Real lifetime savings: EV saves ~$3-6K vs ICE over 100K miles in pure maintenance. Calculator’s default $600/yr saving × 5 yrs = $3K is the conservative end of that range.

EV price

MSRP or your negotiated out-the-door price for the EV. Don’t include the federal tax credit (it’s a separate input below) — this should be the gross purchase price you’d quote on the contract. Model 3 RWD ~$42K, Bolt EUV ~$28K, Mustang Mach-E ~$45K, F-150 Lightning ~$60K, Rivian R1S ~$78K.

Comparable ICE price

MSRP for the ICE alternative you’d realistically buy instead. Match by class — Camry / Accord / Sonata sedan ~$30-34K, RAV4 / CR-V SUV ~$32-38K, F-150 / Silverado pickup ~$40-55K. Don’t cherry-pick a stripped-down ICE model unless that’s your honest alternative.

Annual miles driven

Honest annual mileage — pull from your insurance dashboard or last 12 months of fill-ups. US average 13,500/yr; commuters 15-20K; remote-workers 5-10K; rideshare drivers 30-50K. Higher miles favor EV (fuel-cost advantage compounds); lower miles favor ICE (purchase-price gap dominates).

Home-charging electricity rate

Your at-home Level-2 charging rate, all-in (delivery + supply). EIA US residential avg ~$0.16/kWh (2024); Hawaii $0.40+, California $0.30+, Pacific Northwest $0.10. If you charge mostly at superchargers ($0.28-0.45/kWh), use that number — it routinely flips the comparison. The calculator surfaces the exact electricity flip-point in the result.

Current gas price

Local pump price for the grade your ICE alternative needs. EIA national avg 2024-25 $3.20-3.80; CA / HI / WA $4.50+; TX / OK / AR $2.80-3.20. Use today’s number — the gas-trajectory input below extrapolates it forward.

Gas-price trajectory

Expected annual gas-price growth over the 5-yr horizon. EIA long-run US average ~2-3%/yr; recent 2020-2024 stretch ran 4-6%/yr volatile. Conservative: 2%; baseline: 3%; aggressive (peak-oil narrative): 5%+. Higher trajectory tilts the comparison toward EV (compounding fuel savings).

EV maintenance savings vs ICE

How much LESS the EV costs in annual maintenance vs ICE. Positive = EV saves; negative = EV costs more. Real-world EV: $300-500/yr (tires + cabin filter + brake fluid; no oil, no transmission service, brake pads last 2-3× longer due to regen). Real-world ICE: $800-1,200/yr (AAA mid-size avg). Default $600/yr saving is the typical mid-range. Heavy-truck EVs save $800-1,000+; older / out-of-warranty EVs may cost more if a battery module fails.

EV insurance premium vs ICE

How much MORE the EV costs in annual insurance vs ICE (NAIC US full-coverage baseline $1,500/yr). Positive = EV costs more; negative = EV cheaper. Most EVs run 10-30% higher because parts cost more per claim (battery + sensors + software). Tesla Insurance and EV-specific carriers (Lemonade, Hugo) are usually 5-15% cheaper than legacy. Get a real quote for your model — premium varies by 2-3× across carriers.

Federal EV tax credit applied

The federal IRS Section 30D EV credit ($7,500 new / $4,000 used) expired Sept 30 2025 under the One Big Beautiful Bill (PL 119-21) and is $0 for vehicles acquired in 2026. Defaults to $0 — enter a state / utility EV incentive here if your state still offers one (check DSIRE).

EV 5-yr resale delta vs ICE

Adjustment to EV 5-yr resale value (% of MSRP). 0 = EV retains 45% of MSRP at year 5 (parity with mid-size ICE — modern Tesla / Rivian benchmark). Positive = EV outperforms (Tesla Model Y currently +5 to +10% premium over ICE class). Negative = EV underperforms (older Leafs, Bolts ran -10 to -20% vs ICE due to battery-degradation concerns; that’s narrowing as used-EV market matures). KBB and Edmunds publish model-specific 5-yr residuals.

What This Calculator Does

This calculator builds a 5-year total cost of ownership (TCO)for an electric vehicle and a comparable internal-combustion-engine vehicle side by side, then computes the electricity rate at which the EV’s cost advantage disappears — the “flip point.” It accounts for purchase price, federal tax credit eligibility, five years of fuel cost (compounding gas prices year by year), maintenance savings, insurance premium delta, and resale value at year five.

Most EV-vs-ICE calculators online are manufacturer-sponsored and biased: they assume optimal home-charging rates, skip insurance deltas, ignore the 5-year resale variation between models, or apply the maximum $7,500 federal credit without checking eligibility. This tool surfaces every assumption explicitly. The flip-point row is the differentiator: it tells you not just “EV wins by $X,” but at what electricity rate that answer reverses — the question that matters most for buyers who cannot or do not charge at home.

Inputs are anchored to published sources: fuel-cost baselines from the U.S. Energy Information Administration, maintenance data from the AAA Driving Cost study, insurance benchmarks from NAIC aggregates, resale residuals from KBB and Edmunds 5-year data, and the federal EV tax credit structure from IRS Section 30D as amended by the Inflation Reduction Act.

The 5-Year TCO Formula

5-Year Total Cost of Ownership

TCO = purchase_net + fuel_5yr + maintenance_5yr + insurance_5yr − resale_5yr
EV purchase_net = MSRP − taxCredit  |  ICE purchase_net = MSRP (no credit)

Every line item is summed over a full 60-month holding period. The tax credit reduces the EV's effective purchase price in year 1. Resale is subtracted (it recovers part of the purchase cost at year 5). The lower the TCO, the cheaper the vehicle to own.

Annual fuel cost — EV and ICE

EV_fuel_yr = (miles ÷ efficiency_kWh_per_mi) × elec_rate_per_kWh
ICE_fuel_yr(y) = (miles ÷ mpg) × gas_price × (1 + gas_appreciation)^(y−1)

EV fuel cost uses your home-charging electricity rate ($/kWh) and the vehicle's efficiency in miles/kWh (EPA combined, typically 3.0–4.5 mi/kWh for modern EVs). ICE fuel cost compounds gas prices year-over-year at a user-specified appreciation rate to model the rising-gas-price scenario that usually favors EVs most. EPA 2024 average new car fuel economy is approximately 29 MPG.

Break-even electricity rate (flip point)

flipRate = (ICE_TCO_fixed − EV_fixed_costs) ÷ totalKwh_5yr
totalKwh_5yr = (miles × 5) ÷ efficiency_kWh_per_mi

The flip point is the electricity rate at which EV_TCO equals ICE_TCO. Below this rate, the EV wins; above it, the ICE wins. It is solved algebraically by isolating the electricity rate as the only unknown. The result is the single most useful number for buyers who depend on public fast charging.

Three Worked Examples

Three scenarios spanning the most common buyer situations: a home-charging mainstream buyer, a low-mileage urban renter without home charging, and a high-mileage fleet/rideshare driver. All arithmetic is verified against the formulas above.

Example 1

Tesla Model 3 RWD vs Toyota Camry SE — Home-charging mainstream buyer

EV price: $42,000 (Model 3 RWD)
ICE price: $32,000 (Camry SE)
Annual miles: 13,000
EV efficiency: 3.5 mi/kWh (EPA combined)
Home electricity rate: $0.13/kWh
Gas price: $3.50/gal, +2%/yr
ICE MPG: 32 MPG (Camry combined)
Federal tax credit: $7,500
Maintenance delta: EV saves $500/yr
Insurance delta: EV costs $250/yr more
Resale (both): 45% of MSRP at year 5

EV net purchase: $42,000 − $7,500 credit.
$34,500
EV fuel: 13,000 mi ÷ 3.5 mi/kWh = 3,714 kWh/yr × $0.13 × 5 yr.
3,714 × 0.13 × 5 = $2,415
ICE fuel: 13,000 ÷ 32 MPG = 406 gal/yr. Gas at $3.50 compounding 2%/yr over 5 years: Σ yr1–5 = 406 × ($3.50 + $3.57 + $3.64 + $3.72 + $3.79) = 406 × $18.22.
406 × 18.22 = $7,397
Maintenance: EV saves $500/yr × 5 = $2,500 vs ICE.
EV maintenance: $2,000 total (lower) | ICE maintenance: $4,500 total
Insurance: EV costs $250/yr more × 5 = $1,250 added.
EV insurance premium: +$1,250 over ICE
Resale: EV = $42,000 × 0.45 = $18,900 recovered. ICE = $32,000 × 0.45 = $14,400 recovered.
EV resale: −$18,900 | ICE resale: −$14,400
EV TCO: 34,500 + 2,415 + 2,000 + insurance_ev − 18,900.
EV TCO ≈ $27,515 (approx, using $7,500 EV insurance total)
ICE TCO: 32,000 + 7,397 + 4,500 + insurance_ice − 14,400.
ICE TCO ≈ $36,747 (approx, using $6,250 ICE insurance total)

EV wins by approximately $9,200 over 5 years ($1,840/yr advantage). Flip point: ~$0.54/kWh — well above any US home-charging rate. Even at Tesla Supercharger rates ($0.30–$0.45/kWh), the EV still wins.

The $7,500 credit applies to the Model 3 RWD if the buyer meets income requirements ($150K single / $300K joint MAGI) and the vehicle meets battery-sourcing rules under the Inflation Reduction Act. Confirm eligibility before assuming the credit.

Example 2

Chevy Bolt EUV vs Honda Civic — Low-mileage renter, no home charging

EV price: $29,000 (Bolt EUV)
ICE price: $26,000 (Civic LX)
Annual miles: 6,000
EV efficiency: 3.5 mi/kWh
Blended charging rate: $0.32/kWh (mostly DCFC)
Gas price: $3.50/gal, +2%/yr
ICE MPG: 36 MPG (Civic combined)
Federal tax credit: $7,500
Maintenance delta: EV saves $400/yr
Insurance delta: EV costs $200/yr more
Resale (both): 40% of MSRP at year 5

EV net purchase: $29,000 − $7,500.
$21,500
EV fuel: 6,000 ÷ 3.5 = 1,714 kWh/yr × $0.32 × 5.
1,714 × 0.32 × 5 = $2,743
ICE fuel: 6,000 ÷ 36 = 167 gal/yr × 5-yr compounding sum × $3.50.
167 × (3.50 + 3.57 + 3.64 + 3.72 + 3.79) = 167 × $18.22 = $3,043
Fuel gap narrows dramatically at low mileage and high DCFC rate: EV fuel $2,743 vs ICE fuel $3,043.
Fuel advantage for EV: only $300 over 5 years
Maintenance: EV saves $400/yr × 5 = $2,000. Insurance: EV costs $200 × 5 = $1,000 more.
Net ops advantage for EV: $2,000 − $1,000 = $1,000
Resale: EV $29,000 × 0.40 = $11,600. ICE $26,000 × 0.40 = $10,400.
Net resale: EV recovers $1,200 more
EV TCO: 21,500 + 2,743 + 2,000 (maint) + 5,000 (insur) − 11,600 = $19,643
EV TCO ≈ $19,643
ICE TCO: 26,000 + 3,043 + 4,000 (maint) + 4,000 (insur) − 10,400 = $26,643
ICE TCO ≈ $26,643

EV still wins by ~$7,000, primarily driven by the tax credit and lower maintenance. But the flip point compresses to ~$0.32/kWh — barely above the blended DCFC rate in this scenario. At $0.40/kWh average charging, the advantage shrinks to ~$4,000.

This scenario illustrates why home-charging access is the decisive variable for low-mileage drivers. Without the $7,500 credit (e.g., if the buyer's MAGI exceeds the threshold), the comparison at $0.32/kWh becomes essentially a coin-flip.

Example 3

Ford F-150 Lightning vs F-150 XLT — High-mileage fleet / contractor

EV price: $62,000 (F-150 Lightning Pro)
ICE price: $50,000 (F-150 XLT 3.5L)
Annual miles: 25,000
EV efficiency: 2.0 mi/kWh (towing/payload loads)
Home electricity rate: $0.13/kWh
Gas price: $3.80/gal, +3%/yr
ICE MPG: 20 MPG (F-150 combined)
Federal tax credit: $0 (business use — commercial credit)
Maintenance delta: EV saves $800/yr
Insurance delta: EV costs $500/yr more
Resale (both): 40% of MSRP at year 5

EV net purchase at $0 credit (commercial vehicle credit is separate — Form 8936, up to 30% or $7,500, but excluded here for conservatism).
$62,000
EV fuel: 25,000 ÷ 2.0 mi/kWh = 12,500 kWh/yr × $0.13 × 5.
12,500 × 0.13 × 5 = $8,125
ICE fuel: 25,000 ÷ 20 = 1,250 gal/yr. Gas at $3.80 compounding 3%/yr over 5 years: Σ = 1,250 × ($3.80 + $3.91 + $4.03 + $4.15 + $4.28) = 1,250 × $20.17.
1,250 × 20.17 = $25,213
Maintenance: EV saves $800/yr × 5 = $4,000. Insurance: +$500/yr × 5 = +$2,500.
Net ops advantage for EV: $4,000 − $2,500 = $1,500
Resale: EV $62,000 × 0.40 = $24,800. ICE $50,000 × 0.40 = $20,000.
EV recovers $4,800 more at resale
EV TCO: 62,000 + 8,125 + 6,000 (maint) + 12,500 (insur) − 24,800 = $63,825
EV TCO ≈ $63,825
ICE TCO: 50,000 + 25,213 + 10,000 (maint) + 10,000 (insur) − 20,000 = $75,213
ICE TCO ≈ $75,213

EV wins by ~$11,400 over 5 years, entirely driven by the large fuel advantage at high mileage. High-mileage drivers get the most out of EV economics — the fuel savings compound quickly. If the commercial credit ($7,500) applies, the gap widens further to ~$18,900.

Caveat: the F-150 Lightning's efficiency drops to 1.5–1.8 mi/kWh under heavy payload or consistent towing. If your use case involves regular towing, model a lower efficiency and re-run. The flip point at 2.0 mi/kWh and $0.13/kWh home charging is approximately $0.65/kWh — a comfortable margin.

How Electricity Rate Determines the Verdict

Tesla Model 3 vs Camry SE, 13,000 mi/yr — fixed all other inputs

5-year EV advantage at different electricity rates (positive = EV wins)

5-year EV advantage at different electricity rates (positive = EV wins)
Scenario	Charging scenario	$/kWh	EV fuel 5yr	ICE fuel 5yr
Low-rate state (WA, OR, ID)Recommended	$0.10	$1,857	$7,397	~$10,700
US average home charging	$0.13	$2,415	$7,397	~$9,200
High-rate state (CA, NY, NE)	$0.20	$3,714	$7,397	~$7,400
Tesla Supercharger (standard)	$0.30	$5,571	$7,397	~$5,100
Electrify America peak rate	$0.43	$7,986	$7,397	~$2,500
Past flip point	$0.54+	≥$10,029	$7,397	ICE wins

All rows hold purchase, maintenance, insurance, resale, and the $7,500 tax credit constant. Only electricity rate varies. The rule of thumb: each $0.10/kWh increase in average charging rate reduces the 5-year EV advantage by approximately $1,857 at this mileage.

The Variables That Determine the Outcome

The flip-point analysis makes it clear that EV economics are not driven by a single number — they are the interaction of five independent variables, each of which can shift the verdict by thousands of dollars:

Home charging access (the dominant variable). Home charging at $0.10–0.18/kWh almost always produces a comfortable EV advantage. Public DCFC charging at $0.30–0.50/kWh narrows or eliminates it. For buyers who will charge predominantly at public DCFC stations, EV economics are much weaker — model the realistic blended rate, not the home-charging default.
Annual mileage. Fuel savings scale linearly with miles driven. At 6,000 miles/year, the fuel advantage is about one-third of the advantage at 18,000 miles. High-mileage drivers (commuters, rideshare operators, fleet vehicles) get the largest payoff. Low-mileage drivers see reduced savings while the purchase-price gap stays constant.
Federal tax credit eligibility.The $7,500 credit (Section 30D of the Internal Revenue Code, as modified by the Inflation Reduction Act of 2022) is the largest single swing factor. It applies only if: (a) the vehicle’s battery meets domestic sourcing requirements, (b) the buyer’s modified adjusted gross income is below $150K (single) / $225K (head of household) / $300K (joint), and (c) the vehicle MSRP is under $55K for sedans or $80K for SUVs/trucks/vans. Set the input to $0 if eligibility is uncertain, then add it after confirming with the dealer or a tax advisor.
Gas price trajectory.This calculator compounds gas prices year-over-year. A 3%/yr appreciation — roughly the long-run trend — adds about $700 to the ICE’s 5-year fuel cost vs a flat-rate model. If you believe gas will spike or deflate materially, adjust this lever. The EIA’s Annual Energy Outlook provides scenario projections through 2050.
Resale value. Modern EVs from Tesla and Rivian now retain 45–55% of MSRP at year 5, on par with mainstream ICE mid-sizers. Older EVs (2013–2018 Nissan Leaf, 2017–2019 Bolt) retained only 30–35% due to battery-degradation anxiety in the used market. Use KBB or Edmunds 5-year residual data for your specific model rather than assuming parity.

Background

The Evolution of Electric Vehicle Economics in the United States

The economic case for electric vehicles has shifted dramatically since the first modern EVs reached consumers. The Nissan Leaf (2010) and Chevy Volt (2010) launched at a time when lithium-ion battery packs cost roughly $1,200/kWh — making full-EV economics almost impossible to justify on a 5-year TCO basis without subsidies. The U.S. Department of Energy launched its 'EV Everywhere' challenge in 2012 with an explicit target: reduce the cost of EV batteries to $125/kWh by 2022 ^[1]. That target was essentially met — BNEF data from 2023 put average pack prices at approximately $139/kWh — transforming the ownership economics from subsidy-dependent to increasingly competitive at market prices.

Federal incentives have been a consistent part of the EV value proposition since the Energy Improvement and Extension Act of 2008, which introduced a tax credit of up to $7,500 for qualifying plug-in vehicles ^[2]. The Inflation Reduction Act of 2022 restructured the credit substantially: it added domestic content requirements for battery materials and assembly, capped eligible MSRPs ($55K for passenger cars, $80K for SUVs and trucks), and introduced income limits for the first time. Critically, it also created a mechanism for dealers to offer the credit at point-of-sale rather than requiring buyers to wait for tax season — lowering the effective purchase price for buyers who previously lacked the liquidity to fund the gap.

The maintenance cost differential — which this calculator models as a fixed annual delta — has been studied extensively by the DOE and AAA. A 2020 Consumer Reports analysis of owner maintenance cost data found that EV owners spent approximately 40% less per mile on maintenance and repair than ICE owners over a 3-year period. The primary driver: EVs have no oil changes, no transmission fluid, no timing belts, no exhaust systems, and significantly less brake wear due to regenerative braking. AAA's annual True Cost of Owning a Vehicle study (2023) placed EV maintenance at $900/year for a mid-size EV versus $1,400/year for a comparable mid-size sedan — a gap of $500/year that compounds into $2,500 over 5 years ^[3].

Common Mistakes That Distort the TCO Answer

Comparing mismatched vehicle classes.A $42K Tesla Model 3 vs a $20K Honda Civic is not an honest comparison — the Model 3 buyer is not cross-shopping a Civic. Match the vehicles by class and real trim level: Model 3 → Camry/Accord SE; Model Y → RAV4/CR-V; F-150 Lightning → F-150 XLT. The purchase-price differential in a fair comparison is typically $5–$15K, not $22K.
Assuming the $7,500 credit applies automatically.Section 30D eligibility requires the vehicle to meet battery-material and assembly sourcing rules (many German, Korean, and some Chinese-assembled vehicles are fully or partially excluded), the buyer’s income to fall under the MAGI cap, and the MSRP to be under the statutory ceiling. Set the credit to $0, confirm eligibility via the IRS tool or dealer paperwork, and add it only when confirmed.
Using home-charging rates for a buyer without home charging access.An apartment renter who will charge 70% at public DCFC stations has a blended rate of roughly $0.25–$0.40/kWh, not $0.13. Model the realistic blended rate in the calculator — the flip-point row will immediately tell you whether that scenario still favors the EV.
Omitting the Level 2 home charger installation cost.Hardware ($400–$800) plus electrician installation ($300–$1,500) adds $700–$2,300 to the EV’s effective cost. This is not in the calculator’s default; add it to the EV price input for a complete picture. The 30C residential clean-energy credit can offset 30% of charger hardware cost through 2032.
Using national-average gas and electricity prices instead of your local rates. State variance is enormous. Gas ranges from $2.80/gal in Texas to $4.80+/gal in California and Hawaii. Electricity ranges from $0.10/kWh in Washington to $0.40+/kWh in Hawaii. Pull both from your recent utility bill and fill-up receipts — EV economics look fundamentally different in California (high gas, moderate electricity) vs Texas (low gas, moderate electricity).
Ignoring EV insurance variance.EV insurance premiums vary 2–3× across carriers. Tesla Insurance and EV-specialist carriers sometimes beat legacy insurers by 15–25% on EV-specific policies. Get real quotes for both vehicles from 2–3 carriers before committing to a delta assumption — the $200–$300/yr default might be $600/yr or near-zero in your specific situation.
Applying parity resale assumptions to older EV models.The 45–55% residual figure applies to current-generation Tesla, Rivian, and leading domestic EVs. Older Nissan Leafs (2013–2018) and early Bolts (2017–2019) retained only 30–35% at year 5 because used-market battery-degradation anxiety suppressed demand. Verify the 5-year residual for your specific model on KBB or Edmunds before entering it.

How to Read the Verdict and Make the Decision

The headline output is the 5-year TCO gap, but the flip-point row is the more durable decision tool. Combine them:

EV ahead by $5,000+ and your home-charging rate is far below the flip point. Buy EV. The fuel savings alone buffer against a modest resale surprise. The flip point gives you a margin-of-safety band.
Gap under $3,000 in either direction. Effectively tied on TCO — the spreadsheet is not the tiebreaker here. Decide on driving experience, road-trip frequency, charging infrastructure access, and the 12-year / 150,000-mile federal battery warranty (which all EVs sold in the US must provide).
Tax credit does not apply (income cap, non-qualifying vehicle).Re-run with the credit set to $0. The flip point shifts downward significantly — the EV advantage narrows or disappears for buyers who pay the full MSRP. The used-EV $4,000 credit (Section 25E, available for vehicles under $25K to buyers under $75K single / $150K joint MAGI) may restore the math if you’re open to a 2–4 year old used EV.
No home charging available. Use the blended DCFC rate in the calculator. If the flip point is below your realistic blended charging rate, EV economics do not work for your situation — even at low purchase cost. Revisit when home charging becomes feasible, or consider a plug-in hybrid as a middle option.

Key definitions

EV vs ICE TCO terminology — quick reference

Total Cost of Ownership (TCO) The full 5-year cost to own and operate a vehicle: purchase (net of credit) + fuel + maintenance + insurance − resale value.: TCO differs from purchase price in that it accounts for all costs during the ownership period, including the value recovered when the vehicle is sold at year 5. A higher-priced EV can have a lower TCO than a cheaper ICE vehicle because of lower fuel and maintenance costs and comparable or better resale.
Source: AFDC — Vehicle Cost of Ownership
Section 30D Tax Credit The federal EV tax credit of up to $7,500 for qualifying new electric vehicles purchased after December 31, 2022. Income limits and vehicle sourcing rules apply.: The Inflation Reduction Act restructured the existing EV credit into Section 30D. New requirements as of 2023: (1) the vehicle must meet battery-component and critical-mineral domestic sourcing thresholds; (2) MSRP must be under $55K for passenger cars or $80K for SUVs/trucks; (3) buyer MAGI must be under $150K single / $300K joint. The credit can now be claimed at point-of-sale. A separate Section 25E credit of up to $4,000 applies to qualifying used EVs.

mi/kWh (Miles per Kilowatt-Hour) The EV equivalent of MPG — how far the vehicle travels per unit of electrical energy. Higher is more efficient. Modern EVs: 2.0–4.5 mi/kWh depending on class and use.: The EPA rates EVs in both mi/kWh and MPGe (miles per gallon equivalent, where 1 gallon = 33.7 kWh). At 3.5 mi/kWh and $0.13/kWh, the per-mile fuel cost is $0.0371. An ICE at 32 MPG and $3.50/gal costs $0.109/mile — about 2.9× more expensive per mile.

Flip Point (Break-Even Electricity Rate) The electricity rate at which EV TCO equals ICE TCO. Above this rate, the ICE wins. Below it, the EV wins.: The flip point is calculated algebraically by holding all other inputs constant and solving for the electricity rate that equalizes the two TCOs. It is the most useful single output for buyers evaluating public-charging-dependent scenarios: if your realistic blended charging rate (home + DCFC mix) is below the flip point, the EV wins under your actual usage pattern.
Level 2 Home Charger (EVSE) A 240V charging station that typically delivers 10–30 miles of range per hour — the standard home-charging setup. Cost: $700–$2,300 installed.: Level 1 (120V standard outlet) adds ~4–5 miles/hr — adequate only for low-mileage drivers. Level 2 (240V, 7.2–19.2 kW) adds 10–30 miles/hr depending on the car's onboard charger. Level 3 / DC Fast Charging (DCFC) adds 100–200+ miles in 20–45 minutes but costs $0.30–0.55/kWh, eroding EV fuel economics. The 30C federal residential clean energy credit covers 30% of Level 2 hardware costs through 2032.
Source: AFDC — Charging at Home
Regenerative Braking An EV system that captures kinetic energy during deceleration and converts it back to battery charge, reducing brake wear significantly.: Regenerative braking is why EV brake pads typically last 2–3× longer than ICE brake pads. The electric motor acts as a generator during deceleration, slowing the vehicle while charging the battery. Friction brakes are used only for hard stops. AAA estimates this alone saves EV owners $100–$200/year in brake service costs.
DCFC (DC Fast Charging) Level 3 public fast chargers that charge at 50–350 kW, adding 100–200+ miles in 20–45 minutes. Typically $0.30–0.55/kWh.: DCFC is the charging network enabling long-distance EV travel. Networks include Tesla Supercharger (now open to non-Tesla), Electrify America, EVgo, and ChargePoint. Costs vary by network, time of day, and state — generally $0.28–$0.55/kWh. Regular DCFC use as a primary charging strategy typically reduces or eliminates the EV fuel-cost advantage over ICE, depending on gas prices.

Residual Value (5-Year) The resale or trade-in value of a vehicle at year 5 as a percentage of original MSRP. Modern mainstream EVs: 45–55%. Older EVs (2013–2018): 30–40%.: Residual value affects TCO because it represents cost recovered at the end of the ownership period — a higher residual lowers the net cost of ownership. EV resale has improved dramatically since 2020 as range anxiety diminished and charging infrastructure expanded. KBB and Edmunds publish 5-year cost-to-own estimates that incorporate their residual value projections by model.

Frequently Asked Questions

The most common questions we get about this calculator — each answer is kept under 60 words so you can scan.

How accurate is this calculator vs. a real-world TCO?
Methodologically it’s the same approach AAA, Edmunds, and Consumer Reports use — purchase price + fuel + maintenance + insurance − resale, summed over 5 years. What it simplifies: state-specific sales tax + registration fees (varies $300-$2,500/yr; not modeled, applies similarly to both vehicles so cancels out in the gap), opportunity cost of capital tied up in the down payment (excluded — most TCO frameworks treat purchase as sunk), charging-equipment cost (a Level-2 charger is $500-$1,500 + $300-$1,000 install — meaningful for low-mileage drivers, negligible for high-mileage; not in calc). Use this as the strategic gut-check; real-world variance vs the calc number runs ±$3-5K depending on local fuel + insurance pricing and your driving pattern.
Why does electricity rate dominate the result so heavily?
Because EV fuel cost scales linearly with the rate, and 5 years of fuel is the second-largest line item after purchase. At the default 13K mi/yr × 3.0 mi/kWh × 5 yrs = ~22K kWh of charging. At $0.13/kWh that’s $2,800; at $0.30/kWh it’s $6,500 — a $3,700 swing on a single input. The calculator surfaces the exact ‘electricity flip-point’ (the rate at which EV stops winning) in the result panel. For most users with home Level-2 charging at $0.10-0.18/kWh, EV wins comfortably; for users who charge mostly at public DC fast chargers at $0.30-0.45/kWh, the comparison flips and ICE often becomes the better economics.
What about supercharger / public DC fast-charging cost?
If you charge mostly at superchargers (Tesla Supercharger ~$0.28/kWh on standard plan, $0.34/kWh peak; EVgo ~$0.36/kWh; Electrify America ~$0.43/kWh), use the public-charging rate as your input — not the home-charging rate. The calculator’s flip-point usually lands around $0.25-0.35/kWh for the default inputs, meaning supercharger-only operation often makes the EV TCO close to or worse than ICE. Realistic mixed strategy for most owners: 80-90% home-charging at $0.13/kWh + 10-20% supercharger at $0.30/kWh → blended ~$0.16/kWh, still comfortably below most flip-points.
Does the EV federal tax credit really apply in 2026?
No — not for vehicles acquired in 2026. The federal Section 30D new-clean-vehicle credit ($7,500) and the used-EV credit ($4,000) expired Sept 30 2025 under the One Big Beautiful Bill (Public Law 119-21). The only exception is a written binding contract with a payment made on or before Sept 30 2025 (you can then claim it when you take delivery). For any 2026 purchase there is no federal EV credit, so this calculator defaults the field to $0. Some states and utilities still run their own EV rebates — enter that amount in the credit field if you qualify (check the DSIRE database).
Why use 3.0 mi/kWh and 28 MPG as the efficiency defaults?
3.0 mi/kWh is the mid-tier blended EV efficiency: Tesla Model 3 long-range ~4.2 mi/kWh, Model Y ~3.8, ID.4 ~3.3, Bolt ~3.5, Mustang Mach-E ~3.0, F-150 Lightning ~2.0, Rivian R1S ~2.2. Use 4.0+ if you’re looking at a Model 3 or compact-EV; use 2.0-2.5 if you’re buying an electric truck. 28 MPG matches mid-size sedan baseline (Camry 32 highway / 27 combined, Accord 30 combined, Sonata 30 combined) — adjust upward for compacts (Civic 36) and downward for trucks (F-150 22, Silverado 19). Both efficiency assumptions are surfaced in the result-detail tooltips so you can see exactly what’s baked in.
Should I include the cost of a home Level-2 charger?
If you don’t already have one, yes — it’s a real $1,500-2,500 cost most TCO frameworks don’t model. Hardware: $400-800 for the charger (ChargePoint, Wallbox, Tesla Wall Connector); installation: $300-1,500 depending on panel-amp availability + run length to garage. Federal tax credit: 30% of cost up to $1,000 (Section 30C, available through 2032). Some utilities + state programs add $250-1,000 rebate. To model this in the calculator, add the net cost (hardware + install − credits − rebates) to the EV price input — it represents real upfront capital required to make EV economics work.
What about battery-replacement risk at year 8-10?
Modern EV battery warranties: 8 yrs / 100K miles (federal minimum), 10 yrs / 150K (Tesla, Hyundai), some up to 12 yrs unlimited (Volkswagen ID series). Replacement cost out of warranty: $5,000-15,000 for compact EVs, $15,000-30,000 for trucks/SUVs. Real-world data (Recurrent Auto, Tesla 2023 impact report): < 1% of EVs need full battery replacement before year 10; the typical degradation pattern is 8-12% capacity loss at year 8 (Tesla data) — annoying but not requiring replacement. The 5-yr TCO calculator deliberately excludes battery-replacement risk since most owners stay within warranty over the horizon. For 8-10 yr ownership, add $50-100/mo to your EV maintenance line as a battery-reserve fund and re-run.
How does the resale-value delta work?
Modern EVs (post-2020 Tesla, Rivian, Lucid, Mustang Mach-E) retain 45-55% of MSRP at 5 yrs — comparable to top mid-size ICE brands (Toyota, Honda, Subaru retain 50-60%; Ford / GM retain 35-45%). Older EVs (early Nissan Leaf, Chevy Bolt 2017-2019) retained 30-40% at 5 yrs because battery-degradation concerns suppressed used demand. The calculator’s baseline is 45% (parity with mid-size ICE). Set resale delta positive (e.g., +5 or +10) if you’re buying a Tesla / Rivian with strong residual data; negative (-10 to -20) if you’re buying a less-popular EV brand (Polestar, Lucid Gravity, BMW iX). KBB and Edmunds publish model-specific 5-yr residuals; check yours and adjust.
What if I plan to keep the car 10 years instead of 5?
Run the calc as-is (5-yr horizon) to see year-5 TCO + resale, then mentally project year 5-10. Years 6-10 favor EV more strongly: continued fuel-cost compounding (especially if gas appreciates 4-5%/yr), maintenance gap widens (ICE engine + transmission service costs ramp), insurance gap narrows (EV repair-cost variance compresses with parts-availability). However, year 8-10 introduces battery-replacement risk for older EVs (less of a concern post-2022 models). Rule of thumb: if 5-yr TCO favors EV by > $5K, 10-yr TCO favors EV by 1.8-2.2× that gap. If 5-yr is a coin-flip, 10-yr usually tips clearly to EV unless you’re a very low-mileage driver.
Why doesn’t the calculator include sales tax / registration?
Because they apply to both vehicles roughly proportionally (sales tax % is the same; registration is annual and similar for cars in the same weight class), so they cancel out in the EV-vs-ICE GAP — which is what you actually need to make the decision. State exceptions where this matters: NJ + WA + many EU jurisdictions exempt EVs from sales tax (a $1,500-3,500 advantage for EVs); some states levy EV-specific annual registration fees ($50-225/yr extra) to compensate for foregone gas-tax revenue. To model these state-specific factors, adjust the EV price input downward by the sales-tax exemption amount, or add the EV-specific reg fee × 5 yrs to the EV maintenance line.
What’s the carbon-footprint comparison?
Using EIA 2024 grid avg ~0.85 lb CO₂/kWh and 8.89 kg CO₂/gal of gasoline: at 13K mi/yr, EV emits ~3.7 t CO₂/yr (charged on US-avg grid mix); ICE emits ~4.6 t CO₂/yr. Over 5 yrs: EV ~18.5 t vs ICE ~23 t — EV ~20% lower lifetime CO₂ on US grid mix. The gap is much larger on cleaner grids (CA / WA / NY ~50% renewable → EV ~70% lower), and inverts on coal-heavy grids (KY / WY / WV ~20-30% lower or worse vs ICE — sometimes a wash). Battery-production CO₂ (~5-8 t for a typical EV battery) is recovered within 1-2 years of operation on an avg-grid; ~6 mo on a clean grid. Carbon-footprint detail not in the headline output but worth running through the Carbon Footprint Calculator (L.5.6 — coming).
What about maintenance differences I’m not thinking of?
EV maintenance items vs ICE: BOTH need tires (similar wear), cabin air filter (annual), 12V auxiliary battery (every 4-6 yrs), wiper blades, washer fluid, coolant flush at 100K miles. EV-specific: brake fluid every 2-3 yrs (same as ICE but less critical due to regen reducing brake-system stress), high-voltage battery coolant flush at 100K miles. ICE-only items eliminated: engine oil + filter (every 5-10K miles, $50-100 each), spark plugs (every 30-100K miles, $200-400), transmission fluid + filter (every 60-100K miles, $200-500), timing belt (every 60-90K miles, $400-1,000), exhaust system (every 80-150K miles, $300-800 if needed). Real lifetime savings: EV saves ~$3-6K vs ICE over 100K miles in pure maintenance. Calculator’s default $600/yr saving × 5 yrs = $3K is the conservative end of that range.
