Auto & Commute dashboard
What your car actually costs.
After housing, the car is most households' biggest line item — and the most-misunderstood. Vendor calculators are biased; bank calculators reduce everything to the monthly payment. CalcBold's Auto & Commute tools surface the line items that actually matter: depreciation, insurance, real commute time costs, EV-vs-gas TCO, lease-vs-buy break-even — all using transparent math you can verify against the source numbers.

Commute Cost + Time Calculator
What your commute actually costs — vehicle (fuel + wear + parking) plus the lost-time cost at your hourly wage. Most calcs only show fuel; this one shows the full bill, then tells you how much remote work would save.

Lease vs Buy Car Calculator
Compare buying vs leasing the same car over your actual stay length. The calculator shows total cost both ways + the break-even year — the ownership length where buying flips from worse to cheaper.

True Cost Per Mile Calculator
Most drivers underestimate by 50%+ because they only count fuel. This calculator forces fuel + insurance + maintenance + depreciation into the picture, then compares against the IRS $0.67/mi standard.

Frequently Asked Questions
The most common questions we get about this calculator — each answer is kept under 60 words so you can scan.
Why a separate Auto category instead of Finance?
Because car decisions have their own math (depreciation curves, vehicle-specific operating costs, commute time-cost) that doesn't fit the standard loan/investment framing. Most online auto calculators are vendor-sponsored and biased; CalcBold's Auto tools use transparent math you can verify against the source numbers (IRS standard mileage, AAA Driving Cost study, EIA fuel data).Are these calculators US-specific?
Mostly yes for v1 — fuel economy in MPG, gas in $/gal, IRS standard mileage rate, US-style auto loans and lease structures. The underlying math (TCO, break-even, mile-cost) is universal; we'll layer UK / India / metric-unit support in a future update once the US versions are stable.How accurate are the depreciation estimates?
We use industry-standard rates as defaults: roughly 15-20% per year for the first 5 years (high in year 1 — about 20%, then ~10-15% afterward). Real depreciation depends on make/model; for a precise number, look up your specific vehicle on Kelley Blue Book or Edmunds True Cost to Own. Our calculators let you enter a custom depreciation rate when you have one.Do you store my vehicle data?
No. All math runs in your browser. Vehicle inputs (MSRP, miles, MPG, etc.) never leave your device. The only outbound call is to our AI proxy to generate the insight paragraph, and that request is not logged.
