Rate analysis
Marginal vs Effective Tax Rate Calculator
Two numbers describe the same tax bill and they are routinely confused. The marginal rate is the rate on your next dollar of taxable income. The effective rate is total federal income tax divided by gross income. This tool computes both from the same 2026 bracket schedule.
The gap between them is not an error or a loophole. It is the mechanical result of a progressive schedule plus a standard deduction that taxes the first slice of income at zero.

How to read the result
A single filer earning $75,000 is in the 22% bracket but pays about 10.2% of gross income in federal income tax. The 22% rate applies only to the $8,500 slice between $50,400 and $58,900 of taxable income.
Watch the jump between $60,000 and $120,000 of gross income: tax rises from roughly $5,020 to $17,570 because income crosses the 12% to 22% boundary. The effective rate moves gradually while the marginal rate moves in steps. That distinction matters when evaluating a raise or a retirement account contribution.
Credits, itemized deductions, capital gains rates and payroll taxes all change the real household picture. This calculator is intentionally narrow so the relationship between the two rates stays visible rather than being buried in other variables.
Use the two rates for different decisions. The marginal rate answers questions about the next dollar: whether a bonus, an extra shift, a Roth conversion or a deductible retirement contribution is worth making this year. The effective rate answers questions about the whole year: what share of income actually went to federal income tax, and how one household compares with a different year or a different filing status. Confusing them leads to the familiar claim that a raise pushed someone into a bracket and made them worse off. The slice table above is the direct antidote, because it shows each rate applied only to its own band of income.
Questions people ask about this figure
Can the effective rate exceed the marginal rate?
Not under this narrow federal-only model. Adding payroll taxes or state tax can produce a combined burden that looks different, but those are separate systems.
Why does the tool use gross income as the denominator?
That is the conventional definition of an effective rate on a pay stub. Using taxable income as the denominator would produce a higher, less intuitive figure, so the result panel labels both.
Does a raise ever push me into a lower take-home pay?
No. A progressive schedule taxes only the incremental dollars at the higher rate. Total after-tax income still rises.
