See exactly how your tax brackets work.
The U.S. uses progressive tax brackets — meaning each slice of your income gets taxed at its bracket's rate, not your entire income at the top rate. This calculator shows that visually, plus the difference between your marginal and effective tax rates.

Rate on your next dollar earned
How your taxable income is taxed
Each slice of income is taxed at its bracket's rate.
The biggest myth in personal finance: "If I earn one more dollar, I'll be in a higher bracket and lose money." That's not how it works. Only the dollars above each bracket threshold are taxed at the higher rate. Earning more never reduces your take-home — it just means slightly more tax on the additional income.
What this means in practice
Your next $1,000 earned
$780 kept
$220 federal tax
$1,000 in pre-tax 401(k)
$220 tax saved
Costs only $780 to your paycheck
The most consequential tax myth in personal finance.
"Don't take the raise — you'll be in a higher tax bracket and actually take home less." Almost every American has heard this. It's wrong. It's been wrong for over a century.
U.S. federal income tax is progressive. The 22% bracket doesn't mean your whole income gets taxed at 22% — it means the slice of income within that range is taxed at 22%. Cross into the 24% bracket and only the dollars above that threshold get the 24% treatment. Everything below it stays taxed exactly where it was.
Earning more income always means more take-home pay. Always. The marginal rate just reduces how much of each additional dollar you keep — never makes you poorer.
Where this DOES matter: when you're deciding between traditional vs Roth retirement accounts, when timing income or capital gains across years, or when figuring out how much a bonus is "worth" after tax. The marginal rate tells you what's happening on the margin. The effective rate tells you the average.
