How your income fills each bracket

How the tax bracket calculator works
Federal income tax is progressive, which means your income is sliced into bands and each band is taxed at its own rate. The tool fills the lowest bracket first, then pours the remaining income into the next band, and so on. It adds the tax from each band to find your total bill, then reports the rate on your last dollar and your blended average rate.
The horizontal chart shows how much of your income lands in each bracket and how much tax that band produces. The darker bar marks your marginal band, the highest rate your income actually reaches.
A quick example
A single filer with $85,000 of taxable income pays 10 percent on the first $11,600, 12 percent on the next chunk up to $47,150, and 22 percent on the rest. The result is a marginal rate of 22 percent but an effective rate closer to 15 percent, because most of the income was taxed in the lower bands.
Things to keep in mind
This tool uses 2024 federal brackets only and assumes you have already subtracted your deductions. It does not include state tax, credits or the alternative minimum tax. For the official thresholds, see the IRS tax rates and brackets page. To turn this into a paycheck figure, pair it with our take home pay calculator.
Frequently asked questions
What is a tax bracket?
A tax bracket is a slice of income taxed at a specific rate. The federal system is progressive, so your first dollars are taxed at the lowest rate and only the income above each threshold is taxed at the next higher rate.
Does being in the 24 percent bracket mean all my income is taxed at 24 percent?
No. Only the portion of taxable income that lands inside the 24 percent band is taxed at that rate. Everything below it is taxed at the lower bracket rates, which is why your effective rate is always lower than your top bracket.
What is the difference between marginal and effective tax rate?
Your marginal rate is the rate on your last dollar of income, the top bracket you reach. Your effective rate is total tax divided by total taxable income, a blended average across every bracket your income passes through.
What income should I enter in this calculator?
Enter your taxable income, which is your gross income minus the standard deduction or your itemized deductions and any above-the-line adjustments. The brackets in this tool apply to taxable income, not to gross salary.
