How to read the gap between your two tax rates
On the defaults the two rates are 22% and 14.6%, and both are correct. The marginal rate answers "what does my next dollar cost?" The effective rate answers "what did this year cost?" Confusing them is the single most expensive misunderstanding in personal tax — it's what makes people turn down raises that would have made them better off.
How your effective and marginal rates are worked out
Both rates come out of the same bracket calculation, and they answer different questions about it. The tax itself is the sum of each slice of taxable income multiplied by that slice's rate. From there, the marginal rate is a lookup and the effective rate is a division.
This calculator applies only the standard deduction — there is no pre-tax field and no itemising — which keeps the comparison clean: gross income in, two rates out.
taxable income = gross income − standard deduction tax = Σ (amount in each bracket × that bracket's rate) marginal rate = the rate of the bracket taxable income lands in effective rate = tax ÷ gross income worked at $120,000 single: taxable = $120,000 − $16,100 = $103,900 10% × $12,400 = $1,240 12% × $38,000 = $4,560 22% × $53,500 = $11,770 tax = $17,570 marginal = 22% (the last dollar's bracket) effective = 14.6% ($17,570 ÷ $120,000)
- gross income
- Total wages before the standard deduction — the effective rate is measured against this, not against taxable income
- standard deduction
- The 2026 standard deduction for your filing status — $16,100 single and married filing separately, $32,200 married filing jointly, $24,150 head of household (Rev. Proc. 2025-32)
- taxable income
- Gross income minus the standard deduction — this is what sets your marginal rate — not your salary
- marginal rate
- The rate charged on your next dollar earned — one of 10, 12, 22, 24, 32, 35 or 37% — always a bracket rate, never an average
- effective rate
- Total tax divided by gross income — a blend of every rate you touched, plus the untaxed deduction — always lower than your marginal rate
The denominator is a choice, and this calculator's choice matters. Dividing by gross income rather than by taxable income means the standard deduction counts as income you earned and didn't pay tax on, which drags the effective rate down further. It's the more honest measure of what the year cost, and it's why the figure here runs below what a calculator dividing by taxable income would report — $17,570 over $103,900 would be 16.9%, not 14.6%. Both are defensible; they measure different things, and neither is your marginal rate.
The effective rate here is federal income tax only. The share of your paycheck that actually leaves is considerably higher once FICA takes 7.65% of gross wages from the first dollar — see the FICA calculator for that half.
Worked examples
Example: $120,000 single — a 22% bracket and a 14.6% rate
The calculator's defaults. A single filer earning $120,000 with the standard deduction and nothing else.
| Gross incomebefore anything | $120,000 |
| Less standard deduction2026 single | − $16,100 |
| Taxable incomewhat the brackets see | $103,900 |
| Tax in the 10% bracketon the first $12,400 | $1,240 |
| Tax in the 12% bracketon the next $38,000 | $4,560 |
| Tax in the 22% bracketon the last $53,500 | $11,770 |
| Total federal taxthe sum of the three | $17,570 |
| Marginal ratethe next dollar costs 22 cents | 22% |
| Effective rate$17,570 ÷ $120,000 | 14.6% |
A 7.4-point gap between the two rates. Someone who believes they "pay 22%" would put their tax at $26,400 — they overstate it by $8,830. The reason is visible in the steps: $50,400 of taxable income was taxed at 10% and 12% before a single dollar reached 22%, and $16,100 was never taxed at all.
Example: $250,000 single — four brackets deep
Drag income to $250,000. The marginal rate jumps two brackets to 32%, and the gap between the two rates widens rather than closing.
| Taxable income$250,000 − $16,100 | $233,900 |
| Tax in the 10% bracketidentical to the $120,000 case | $1,240 |
| Tax in the 12% bracketalso identical — the bottom never changes | $4,560 |
| Tax in the 22% bracketon the full $55,300 band | $12,166 |
| Tax in the 24% bracketon $96,075 — the widest band, and the biggest bar | $23,058 |
| Tax in the 32% bracketon the last $32,125 only | $10,280 |
| Total federal taxacross five brackets | $51,304 |
| Marginal ratethe next dollar | 32% |
| Effective rate$51,304 ÷ $250,000 | 20.5% |
The gap grew from 7.4 points to 11.5. Note the 32% bar is not the tallest — the 24% bracket contributes $23,058 against the 32% bracket's $10,280, because it's three times as wide. And the first two bars are byte-for-byte identical to the $120,000 example: doubling your income changed nothing whatsoever about how your first $50,400 of taxable income is taxed. That is what progressive means, and it's the reason a raise can never leave you worse off.
Frequently asked questions
Why is my effective tax rate lower than my tax bracket?
Because your bracket only describes your last dollar. Every dollar below it was taxed at a lower rate on the way up, and the deduction at the bottom was taxed at nothing — so the average across all of it lands well under the top rate.
The defaults show the shape: $120,000 of gross income, a 22% bracket, and a 14.6% effective rate. The first $16,100 was untaxed, the next $12,400 taxed at 10%, the next $38,000 at 12%, and only the final $53,500 at 22%. The gap widens as you climb, not narrows — at $250,000 the marginal rate is 32% and the effective rate is 20.5%, a difference of 11.5 points. Your effective rate approaches your marginal rate only in the limit, and never arrives.
Does moving into a higher tax bracket mean all my income is taxed at that rate?
No, and this is the misunderstanding the bar chart on this page exists to kill. Brackets apply to slices of income, not to the whole of it. Crossing into the 24% bracket means the dollars above that threshold are taxed at 24% — every dollar below it keeps the rate it already had.
The second example makes it concrete: at $250,000 the tax in the 10% and 12% brackets is $1,240 and $4,560, exactly the same dollars as at $120,000. Nothing about the raise reached back and re-taxed them. This is why a raise can never reduce your take-home pay through brackets alone — the extra dollars are taxed at 32%, so you keep 68 cents of each, which is less than a dollar but comfortably more than zero. (Benefit cliffs and credit phase-outs can produce genuine losses, but they are not brackets, and this calculator models none of them.)
How do I calculate my effective tax rate?
Divide your total tax by your income — but decide which income first, because the answer moves. On a filed return the common method is line 24 (total tax) divided by line 15 (taxable income). This calculator instead divides by gross income, which on the defaults gives 14.6% where the taxable-income method gives 16.9% for the same $17,570 of tax.
Neither is wrong; they answer different questions. Dividing by taxable income tells you the rate on the money the brackets touched. Dividing by gross income tells you what share of everything you earned went to federal income tax — which is usually what people mean when they ask. What no version includes is FICA, state tax, or anything beyond federal income tax, so a real "share of my income that goes to tax" figure is meaningfully higher than either.
Do capital gains push my ordinary income into a higher tax bracket?
Long-term gains, no. Short-term gains, yes. Long-term capital gains and qualified dividends are taxed on their own 0/15/20% schedule and are stacked on top of your ordinary income — your salary is taxed first and fills the lower brackets, then the gain is taxed in whatever space remains above it. The causation runs one way: your income raises the rate on your gain, never the reverse.
Short-term gains have no separate schedule at all. They are ordinary income, they enter the same brackets shown on this page, and they absolutely can lift your marginal rate. Neither type is modelled by this calculator — enter only wages here, or the rates will be wrong. The capital gains tax calculator handles the stacking properly.
Where these two rates stop being the whole picture
The bracket arithmetic here is exact for ordinary income against the 2026 schedule. Almost everything that makes a real marginal rate differ from a bracket rate is outside it.
- Your real marginal rate is higher than 22% — The rate shown is federal income tax only. Add 7.65% of FICA on wages, plus state income tax where it applies, and the true cost of your next dollar is well above the bracket figure. For a self-employed filer the payroll component is 14.13% rather than 7.65%.
- Standard deduction only — No pre-tax contributions, no itemising, no credits. A traditional 401(k) contribution lowers taxable income and can drop your marginal rate a bracket — this page has no field for it, so it will report a higher marginal rate than a contributing filer actually faces.
- Phase-outs create rates that aren't on the chart — Credits and deductions that taper as income rises produce effective marginal rates that no bracket table shows — a dollar that costs 22% in tax and simultaneously withdraws 5 cents of a credit has a real marginal rate of 27%. None of that appears here.
- Both rates go to zero before the income does — Below about $16,100 of gross income the standard deduction wipes out taxable income entirely: the tax is $0, the effective rate is 0%, and the chart shows nothing. The marginal card still reads 10%, because that is what the next dollar of taxable income would cost — the two cards are answering different questions, and at the bottom of the slider the gap between them is the whole point.
- One year, one income — Both rates are snapshots. The marginal rate that matters for a decision is the one in the year the money lands, which is why a Roth conversion or a large sale is judged against next year's expected bracket rather than this year's.
