Tax Bracket Calculator

Your bracket is not your tax rate

The single most expensive misunderstanding in personal finance is the idea that "being in the 24% bracket" means you pay 24% of everything you earn. You don't. The United States uses a progressive, marginal system: your income is sliced into chunks, and each chunk is taxed at its own rate. The first dollars are taxed at 10%, the next band at 12%, then 22%, and so on. Only the income that spills into the top band gets taxed at that top rate. So someone "in the 24% bracket" might actually hand over an effective rate closer to 14%–17% once you blend all the bands together.

This matters in real life. People sometimes turn down a raise or a bonus because they're afraid it will "bump them into a higher bracket" and cost them money — but that can never happen. A raise only taxes the new dollars at the higher rate; every dollar you already earned stays taxed exactly as before. You always take home more after a raise, full stop. This calculator makes that visible by showing both your marginal bracket (the rate on your next dollar) and your effective rate (what you actually pay overall), plus how much tax a hypothetical extra $1,000 would trigger.

One important note on the input: enter your taxable income — that's your gross pay minus your deductions. Most filers take the standard deduction ($15,000 for single filers and $30,000 for married couples in 2025), so a $90,000 salary often becomes about $75,000 of taxable income. The brackets below are the official 2025 federal figures used on returns filed in 2026, and they don't include state income tax, FICA, or credits.
