2026 federal brackets, single or married filing jointly only. Only your last dollar of taxable income is taxed at the marginal rate — every dollar before it is taxed at the lower rates shown above, which is why the effective rate is always lower.
"Moving into a higher tax bracket" is one of the most commonly misunderstood ideas in personal finance — it does not mean all of your income suddenly gets taxed at the higher rate. Only the slice of income inside that bracket is taxed at it; everything below continues to be taxed at the lower rates it already fell into.
This calculator applies the 2026 standard deduction to your gross income, runs the result through the federal bracket table, and shows both numbers side by side: your marginal rate (the rate on your next dollar) and your effective rate (the rate on your income as a whole) — plus the full bracket-by-bracket breakdown behind the total.
The Effective vs Marginal Tax Rate formula
Taxable income = max(0, gross income − standard deduction); Tax = 2026 progressive bracket tax on taxable income; Marginal rate = rate of the highest bracket reached; Effective rate (taxable income) = tax ÷ taxable income; Effective rate (gross income) = tax ÷ gross incomethe standard deduction is $16,100 (single) or $32,200 (married filing jointly) for 2026; both effective rates are 0 when the corresponding denominator is 0.
Worked example
A single filer with $76,100 of gross income: taxable income after the $16,100 standard deduction is $60,000. That comes to $7,912 of federal tax — $1,240 at 10% on the first $12,400, $4,560 at 12% on the next $38,000, and $2,112 at 22% on the remaining $9,600. The marginal rate is 22%, the effective rate on taxable income is about 13.19%, and the effective rate on gross income is lower still, about 10.40%.
Assumptions, rounding, and limitations
Assumptions
- Only the 2026 standard deduction is applied — itemized deductions are not modeled.
- No tax credits are subtracted; the result is tax owed before credits.
- Every dollar of entered gross income is treated as ordinary taxable income; this does not distinguish capital gains or other income taxed under different rules.
Rounding: All figures are computed at full floating-point precision and rounded only for currency display.
Limitations
- Federal tax only — no state or local income tax is included.
- Filing status is limited to single and married filing jointly.
- Does not model tax credits or itemized deductions.
- Not tax advice; consult a tax professional for your specific situation.

How a progressive bracket actually works
Each bracket's rate applies only to the portion of your taxable income that falls inside it. If you are in the 22% bracket, that does not mean you pay 22% of your entire income — the first slice is still taxed at 10%, the next slice at 12%, and only the top slice at 22%. The marginal rate is the rate on your last dollar of taxable income, not an average of anything.
Two different effective rates
This calculator reports two effective rates because they answer different questions. Effective rate on taxable income divides your tax by the income left after the standard deduction — the number tax professionals usually mean by 'effective rate'. Effective rate on gross income divides the same tax by your income before any deduction, which is usually lower and closer to what most people intuitively expect their 'overall tax rate' to be.
What this does not model
Only the 2026 standard deduction is applied, filing status is limited to single and married filing jointly, and no tax credits (such as the child tax credit) are included. State and local income tax are entirely out of scope. Use this to understand bracket mechanics and your federal position, not as a complete tax return.
Frequently asked questions
▶What's the difference between marginal and effective tax rate?
Marginal rate is the rate applied to your next dollar of taxable income — the top bracket you reach. Effective rate is your total tax divided by your income, blending every lower bracket you passed through on the way. Effective rate is always lower than or equal to marginal rate.
▶If I get a raise that pushes me into a higher bracket, do I take home less overall?
No. Only the portion of income inside the new bracket is taxed at the higher rate — every dollar you were already earning keeps being taxed at the same rates as before. A raise can never reduce your total after-tax income under this bracket structure.
▶Why does the calculator show two different 'effective rate' numbers?
One effective rate is computed on taxable income (after the standard deduction), and the other on gross income (before it). They answer different questions, and gross-income effective rate is always the lower of the two since the deduction itself was never taxed.
▶Does this include state income tax?
No — this covers federal income tax only. State and local rules vary too widely by jurisdiction to model here.
▶Does this calculator apply tax credits?
No. It computes federal tax owed before credits. Credits such as the child tax credit would reduce the final tax owed further, which this calculator does not model.
