Free Raise Impact Calculator — Net Take-Home After Marginal Tax

What This Calculator Does

A raise impact calculator answers the only question that actually matters when HR slides the offer letter across the table: how much of this raise will I actually keep? The number announced in the meeting is the gross raise — the headline figure that gets discussed at backyard barbecues and whispered about over Slack DMs. The number that lands in your bank account is the net raise, and the gap between the two is almost always larger than people expect. A $10,000 raise at a 30% combined marginal rate is $7,000 of new spending power, not $10,000. That $3,000 gap is where lifestyle inflation gets planned, where mortgage applications get denied, and where carefully built budgets quietly fall apart.

The mechanics behind the gap are a single concept most people get wrong: marginal tax versus effective tax. Your effective rate is the blended average across every dollar you earn — the headline figure on your annual return. Your marginal rate is the rate that applies to the nextdollar you earn, which is the rate that applies to every dollar of a raise. On a $100,000 single filer the effective federal rate is roughly 17%, but the marginal rate is 22%. Add FICA (7.65%) and state tax (anywhere from 0% in Texas to 13.3% at California’s top tier) and the marginal rate on a raise comes in around 30–40% for most US tech and professional workers. That number — not the effective rate — is what eats your raise.

Once the calculator gives you the net annual figure, the more useful framing is the per-paycheckview. A $7,200 net raise on a biweekly schedule is $277 per check; on a monthly schedule it’s $600. That’s the number that should drive any decision about whether to start a new gym membership, upgrade the car payment, or commit to a higher rent. Budgeting against the gross raise is the single most reliable way to feel broke after a pay rise — you’ve already mentally spent dollars that the IRS, FICA, and the state revenue agency have first claim on. The calculator collapses all of that into one screen so you know the real cash flow before you spend it.

The Math: Marginal Tax on the Raise

The formula is deliberately stripped down to the three lines that matter. Every dollar of a raise sits at the top of your income stack — the highest brackets you touch — so the marginalrate is what applies to the entire raise, not your effective average. That’s why the math is so much simpler than the full take-home calculation: you don’t need to redo the bracket math for the bottom dollars; you only need to apply the marginal rate to the new dollars. The calculator accepts either a percentage raise (multiplied against your current salary) or a direct dollar amount, then asks for your best estimate of marginal rate, then returns the net annual, biweekly, and monthly figures.

For US tech and finance workers the marginal-rate input typically lands somewhere between 30% and 40%. Build it from the parts: the federal bracket you’re sitting in (22% at $50K–$105K single, 24% at $105K–$202K, 32% at $202K–$257K, 35% at $257K–$642K, 37% above), plus FICA at 7.65% (which drops to 1.45% above the Social Security wage base of roughly $168,600 in 2024 / $172K projected 2026), plus your state income tax (0% in TX/FL/WA/NV/SD/WY/AK/TN, ~5% Virginia, ~6% New York, up to 13.3% California). A $150K Californian sits at roughly 24% federal + 7.65% FICA + 9.3% state = 40.95% marginal, which is why Bay Area engineers consistently feel like their raises evaporate. A $150K Texan sits at 24% + 7.65% + 0% = 31.65%, and the same gross raise lands roughly $1,400/year more in net dollars.

Why Marginal ≠ Effective

This is the single most consequential misunderstanding in personal finance, and the one most likely to make people turn down promotions, decline raises, or talk themselves out of bonuses on the theory that “it’ll just push me into the next bracket.” Here is the rule, stated as plainly as possible: in a US progressive bracket system, only the dollars above each threshold get taxed at the higher rate. The dollars below the threshold remain taxed at the lower rate they were taxed at before. There is no cliff. There is no penalty. Getting a raise never reduces your total take-home pay. The worst case is that some of the new dollars are taxed at a higher marginal rate than the old dollars; you still keep more than you had before.

Example. A single filer at $100,000 of taxable income pays about $17,400 in federal tax (a blend of 10% on the first $11,925, 12% on the next $36,725, and 22% on the remaining $51,350 in 2025 numbers). The effectiverate is $17,400 ÷ $100,000 = 17.4%. The marginalrate is 22% — the rate that applies to the next dollar earned. If this person gets a $10,000 raise, the new dollars get taxed mostly at 22% (and a sliver at 24% if the raise crosses the bracket threshold). The existing $100,000 keeps being taxed exactly as before. The headline rate didn’t change for the original dollars; only the new ones face the higher rate.

The practical consequence: when you plug a raise into this calculator, do not enter your effective rate. Enter your marginalrate — the highest combined bracket your income reaches, plus FICA, plus state. The most common mistake is entering 17% (effective) when the correct number is 32% (marginal), which produces a wildly optimistic net figure that the actual paycheck then fails to deliver. If you’re unsure which rate is which, run your current salary through our take-home pay calculator— the marginal rate it surfaces is the right input for this tool.

How to Use This Calculator

1. Enter your current annual salary— the gross figure on your most recent offer letter or last year’s W-2 box 1 (before pre-tax deductions). This number is needed only when you express the raise as a percentage; if you have the dollar amount of the raise directly, the current salary becomes a sanity check rather than a required input.
2. Enter the raisein your preferred unit. Either a percentage (e.g. 5 for a 5% raise — the calculator multiplies by current salary to derive the gross dollar amount) or a direct dollar amount (e.g. $10,000 for a flat raise or annualized bonus). For one-time bonuses, divide by the period you want amortized over — or just enter the bonus amount itself to see the net of the lump sum.
3. Enter your marginal tax rate. Build it as federal bracket + FICA + state. For most US W-2 earners this lands between 22% and 45%. Quick estimates: $80K single in a no-state-tax state ≈ 29.65%, $150K single in California ≈ 40.95%, $250K single in NYC ≈ 45%+. When in doubt, round up — under-estimating the marginal rate is the more common error and produces over-optimistic net numbers.
4. Read the three outputs together: net annual raise (dollars per year that actually arrive), net biweekly (per-paycheck delta on the standard 26-pay schedule), and net monthly(the most useful unit for budgeting against rent, mortgage, car payments, and subscription stacks). The percentage-of-gross-kept figure is the gut-check — if you’re keeping less than 65% of a raise, you’re in a high-marginal regime and should be aggressive about pre-tax deferrals.
5. Stress-test the answer. Re-run with the marginal rate bumped 3–5 percentage points to account for the 401(k) auto-increase that frequently triggers off raises (most plans step contribution up 1% per year automatically), the FICA wage-base recapture if your new salary crosses the Social Security threshold mid-year, and any state-tax surcharges that activate at higher income tiers (California’s 1% mental-health surcharge above $1M, New York’s tiered surcharges above $1M and $5M, etc.). The conservative number is the one you should budget against.

Three Worked Examples

Three real raise scenarios at the income tiers where the marginal-rate gap matters most. Plug any of them into the calculator above to see the per-paycheck breakdown the tool produces.

Example 1 — The mid-career raise ($80K → $90K)

Setup: $80,000 base, single filer in a 5% state-tax state, getting a $10,000 raise to $90,000. Federal bracket sits at 22% (well below the $105K threshold for the 24% bracket), FICA is the full 7.65% (still under the SS wage base), state is 5%, local is 0%. The combined marginal rate is roughly 22 + 7.65 + 5 = 34.65% — but for round numbers, say 28% to keep this example clean as a textbook case.

Math:Gross raise = $10,000. Tax on raise at 28% marginal = $2,800. Net raise = $10,000 − $2,800 = $7,200/year. On a biweekly schedule (26 paychecks/year) that’s $7,200 ÷ 26 = $277/paycheck. On a monthly schedule it’s $7,200 ÷ 12 = $600/month. Of every gross dollar of raise, this earner banks 72¢.

Reading the result:$600/month is enough to materially move a budget — a meaningful car-payment upgrade, a noticeable rent bump, a real retirement contribution. At this income tier the “save the raise” rule is most powerful: route the entire $277/paycheck into a 401(k) increase before lifestyle creep notices. You don’t feel the deduction (your old paycheck wasn’t getting it anyway), and you’ve just added $7,200/year of tax-deferred compounding to your retirement track without changing your lifestyle by a single dollar.

Example 2 — The senior IC raise ($150K + 8%)

Setup:$150,000 base, single filer in a 5% state, getting an 8% raise = $12,000 to $162,000. Federal bracket sits at 24% (above the $105K threshold, below the $202K threshold). FICA: most of the salary is below the SS wage base of ~$172K, so the bulk of the raise still gets the full 7.65% — but at the very top end the SS portion starts to fall off and only Medicare 1.45% applies. State 5%. Combined marginal: approximately 24 + 7.65 + 5 = 36.65%; we’ll use 32% as a slightly rounded illustration.

Math:Gross raise = $12,000. Tax on raise at 32% marginal = $3,840. Net raise = $12,000 − $3,840 = $8,160/year. Biweekly: $8,160 ÷ 26 = $314/paycheck. Monthly: $8,160 ÷ 12 = $680/month. Of every gross dollar of raise, this earner banks 68¢.

Reading the result:Notice the percentage-kept figure has dropped from 72% to 68% — that’s the marginal rate doing exactly what it’s designed to do. At this tier the calculator’s most useful output is the realization that an 8% gross raise translates to roughly 5.5% real spending-power increase. The negotiation lever is also clearer: pushing for an extra $5K of base nets only $3,400 after marginal tax, while pushing for a $5K signing bonus paid one-time can sometimes be negotiated more easily and nets the same after withholding. Pre-tax 401(k) and HSA contributions are now non-optional — every dollar deferred saves 32¢ immediately.

Example 3 — The high-earner bonus ($200K base + $30K bonus)

Setup:$200,000 base, single filer in a 5% state, receiving a $30,000 annual bonus. The bonus pushes the all-in income to $230,000 — through the 32% bracket threshold at $202,300 and into the 32% band. Most of the bonus dollars get taxed at 32% federal + 5% state. FICA is largely Medicare 1.45% only at this income (the SS wage base of ~$172K is already passed by the regular salary). Add the 0.9% Additional Medicare surcharge above $200K. Combined marginal on the bonus: roughly 32 + 1.45 + 0.9 + 5 = 39.35%; round up to 37% as a worst-case framing for this example.

Math:Gross bonus = $30,000. Tax at 37% marginal = $11,100. Net = $30,000 − $11,100 = $18,900. If we annualize this as if it were a per-year raise on the biweekly schedule: $18,900 ÷ 26 = $727/paycheck equivalent. Of every gross dollar, this earner banks 63¢— barely more than half once the realistic 40%+ blended rate is acknowledged.

Reading the result:This is the marginal-pinch zone. High earners feel raises and bonuses the least proportionally because the bracket math is the most punitive at the top. There’s a separate wrinkle: federal bonus withholding is a flat 22%up to $1M and 37% above, regardless of your actual bracket. So this $30K bonus gets $6,600 withheld at the federal level on the day it’s paid — but the actual tax owed at filing is roughly $11,100. The difference ($4,500) lands as a tax bill in April unless quarterly estimated payments or year-end W-4 adjustments cover the gap. That’s why high earners often see big refunds with bonuses that are paid late in the year (the flat 22% over-withholds for someone in the 32%+ bracket, then equilibrium gets restored at filing). The lesson: always run the bonus through this calculator at your real marginal rate, not the IRS’s flat 22% withholding rate — the “net” check you receive is rarely the net you actually keep.

Common Mistakes

• Using effective rate instead of marginal.A $150K earner with a 22% effective rate plugs in 22% and sees a $10K raise net to $7,800. The actual net at the true marginal rate of ~37% is closer to $6,300 — a $1,500 budgeting error. Always enter the rate that applies to the nextdollar, not the average across all dollars. If you’re unsure, the marginal rate is roughly your federal bracket + 7.65% (FICA, dropping to 1.45% above the SS wage base) + your state rate.
• Assuming the whole salary gets re-taxed at the higher bracket.The classic “don’t give me the raise, it’ll push me into a worse tax bracket” objection. It’s wrong every time. The progressive system only taxes the dollars above each threshold at the higher rate; the dollars below stay where they were. Crossing into a new bracket never decreases your total take-home; it only decreases the percentage of the new dollars you keep.
• Not factoring in 401(k) auto-increase.Most modern 401(k) plans nudge your contribution rate up by 1% each year automatically — and frequently sync that increase to the date of your annual raise. So your gross raise of $10,000 also triggers a $1,500 increase in 401(k) deferral (1% of $150K), which further reduces take-home today but adds to retirement compounding. The calculator output is the pre-deferral net; your actual paycheck delta will be smaller if your plan does this auto-step. Check your plan settings before you budget.
• Comparing pre-tax raises against post-tax bills.“A $10K raise covers my $8K rent increase” — only if you’re budgeting against gross, which you shouldn’t. The $10K raise is $7K net at a 30% marginal rate. The $8K rent increase is paid in post-tax dollars. The math: $7K of new spending power versus $8K of new spending requirement = a $1K shortfall, not the apparent $2K cushion. Always compare net-of-tax raise against post-tax bills.
• Ignoring state tax differences when relocating.A move from California (13.3% top state) to Texas (0% state) at the same gross salary is a real raise of ~13% before any nominal increase. A raise from $150K California to $150K Texas, with the marginal tax rate shifting from ~41% to ~32%, lands roughly $13,500 more in your bank account every year — even though the offer letter looks identical. This calculator handles the marginal-rate input directly, so re-running with the destination state’s rate is the cleanest way to see the relocation premium. Pair it with the take-home pay calculator to see the full net comparison.
• Treating bonuses identically to raises.They look the same on a W-2 line but they withhold differently. Bonus dollars get federal flat-withheld at 22% (up to $1M) regardless of your real bracket; a raise gets withheld at your projected annual rate. The actual tax owed equalizes at filing, but the cash-flow timing is different. A $30K bonus to someone in the 32% bracket gets $6,600 withheld on payment day; the additional ~$3,000 owed gets settled in April. Plan for it — either bump W-4 withholding or set aside the delta in a savings account.

When This Calculator Decides For You

1. Whether a 5% raise actually moves the needle on lifestyle.5% gross at a 35% marginal rate is 3.25% net. On a $100K salary that’s $3,250/year = $271/month. That’s a meaningful retirement contribution but probably not a lifestyle change. The calculator forces the conversation: if the goal is to feel the raise, the gross number needs to be 10%+ in most marginal regimes. Anything under 5% net is functionally invisible and should be saved rather than spent — which is exactly why the savvy move is to route it into investments before lifestyle inflation notices.
2. Budgeting the new amount before payday hits. The fastest way to lose a raise is to wait for the first new paycheck and then start spending against the bigger number you saw on your pay stub. By that point lifestyle has already crept. Run the calculator the day the raise is announced; pre-allocate the net biweekly figure into 401(k) increase, brokerage auto-deposit, or savings transfer; let the new paycheck arrive already-spoken-for. The behavior research is unambiguous: pre-committed savings beats post-hoc savings 10-to-1.
3. Deciding whether to push for $X more in negotiation.“Can you do $5K more on base?” sounds like a $5K ask. After 35% marginal it’s a $3,250 net ask — which makes the negotiation easier to frame internally and easier to justify to a manager. Conversely, $5K of signing bonus negotiated up-front (which sometimes comes from a different budget pool than base salary) lands at the same $3,250 net but is often easier for the recruiter to grant. The calculator gives you the exact net number on each option so the “ask” conversation is grounded.
4. Comparing two offers with different bases. Offer A is $150K in California; Offer B is $135K in Texas. The headline says A wins by $15K. Run both marginal rates through this calculator: A at ~41% nets $88,500; B at ~32% nets $91,800. Offer B wins by $3,300 net despite losing by $15K gross. That kind of inversion is common at the state-tax extremes and almost never visible without explicitly running the marginal math. Pair the result with the take-home pay calculator for the full per-paycheck view.
5. Deciding whether the relocation tax savings outweigh the move costs.A California-to-Texas move at $200K saves roughly $18,600/year in state tax alone (9.3% California marginal × $200K). Move costs (movers, lease break, deposit, school changes) are usually $15–30K one-time. The calculator quantifies the annual savings; you decide whether the lifestyle trade is worth the payback period. A 1-year payback on $200K is the typical pattern; a 2-year payback at $150K. Higher up the income ladder the relocation math gets more lopsided in favor of the no-tax state.

What This Calculator Doesn’t Model

• Social Security wage-base mid-bracket transitions.The 6.2% Social Security portion of FICA only applies up to the annual wage base ($168,600 in 2024, ~$172K projected for 2026). Above that threshold only Medicare 1.45% applies. If your raise pushes you across the wage base mid-year, your effective FICA rate on the raise changes partway through — the bottom dollars get full FICA, the top dollars get only Medicare. The calculator uses a single marginal rate, so this transition isn’t captured. For raises that straddle the wage base, the actual net is slightly higher than the calculator shows.
• AMT (Alternative Minimum Tax).A parallel tax system that affects high earners with large deduction stacks, ISO exercises, or unusual income mixes. AMT can dramatically alter the marginal rate on a specific dollar of new income, particularly for incentive-stock-option holders and earners with state-tax deduction caps biting. AMT is rare under current rules (the 2018 tax law dramatically narrowed who hits it), but it exists and the calculator doesn’t model it.
• Benefit-cliff effects from tax-credit phaseouts.A raise can phase out the Child Tax Credit, the Earned Income Tax Credit, education credits, the Saver’s Credit, and ACA premium subsidies — each of which acts like an additional marginal tax in the phaseout band. For families in the $50–$200K range these phaseouts can add 5–15 percentage points of effective marginal rate on raise dollars without showing up in any bracket table. The calculator only sees the headline marginal rate.
• Bonus flat 22% withholding mechanics.The IRS requires employers to withhold supplemental wages (bonuses, commissions, severance) at a flat 22% federal rate up to $1M per employee per year, then 37% above. This is a withholding rate, not a tax rate — the actual tax owed gets calculated at filing using your real marginal rate. For high earners, the 22% under-withholds and you owe more in April; for low earners, the 22% over-withholds and you get a refund. The calculator returns the tax-owed number, not the cash-in-hand-on-bonus-day number.
• Equity / RSU vesting on top of base raise.Annual reviews often refresh equity grants in addition to base salary. RSU vests get taxed at supplemental withholding (22% federal up to $1M, plus FICA, plus state) on the vest date, and the actual tax equalizes at filing. Refresh grants, performance-based units, and stock-price appreciation between grant and vest all change the all-in compensation picture in ways this single-rate calculator doesn’t capture. For the full equity-aware view, pair this tool with the job offer comparison calculator.

For the rest of the picture beyond the raise itself, work through the full set of career calculators: pipe the new salary through the take-home pay calculator for the per-paycheck net view across federal, FICA, and state, translate the gross figure into a rate per scheduled hour with the salary-to-hourly calculator, back out commute time and work expenses with the true hourly rate calculator to see what the raise is really worth per hour of life spent on the job, and project the long-term compounding upside of routing the raise into investments with the compound interest calculator. The raise impact calculator is the gateway; the others sharpen each dimension — per-paycheck cash flow, per-hour valuation, and decade-scale wealth.
