What is the Tax Bracket Calculator?

This calculator applies the 2024 US federal income tax brackets to your income and filing status, then breaks down exactly how much tax you owe, your effective rate, your marginal rate, and an estimated take-home pay per month, paycheck, and week. It automatically applies the standard deduction for your filing status and lets you enter pre-tax deductions like 401(k) or HSA contributions.

How to Use It

Enter your annual gross income, choose your filing status (single, married filing jointly, head of household, or married filing separately), and add any pre-tax deductions. Click Calculate Tax to see a bracket-by-bracket breakdown showing exactly how much income falls into each rate and how much tax that bracket contributes.

When to Use It

Use it to estimate your federal tax bill before filing, to see how a raise, bonus, or new 401(k) contribution changes your marginal and effective rates, or to understand why earning more never reduces your take-home pay — only the income above each threshold is taxed at the higher rate. It's also useful for comparing job offers or planning paycheck withholding.

Who Benefits

Employees and salaried workers estimating their tax liability, freelancers and contractors planning for owed tax, anyone negotiating a raise or new job offer, and people deciding how much to contribute to pre-tax retirement accounts all get a clear picture of federal tax owed. Note that this tool covers federal income tax only — state tax and FICA (Social Security and Medicare) are not included and will further reduce take-home pay.

Frequently Asked Questions

Your marginal rate is the rate on your last dollar of income — the highest bracket you reach. Your effective rate is the actual percentage of your total income paid in taxes. For example, a single filer earning $75,000 has a 22% marginal rate but an effective rate of around 13–14%, because only a portion of income is taxed at 22%. This calculator shows both.

Yes — but only on the additional income. A common misconception is that earning $1 more can push all your income into a higher bracket. In reality, only the income above the bracket threshold is taxed at the higher rate, which this calculator's bracket-by-bracket breakdown makes visible. You will always take home more money overall by earning more.

This calculator estimates federal income tax only, using the standard deduction for your filing status. It doesn't include state income tax, FICA (Social Security 6.2% and Medicare 1.45%), or itemized deductions, all of which affect your actual take-home pay. Use the pre-tax deductions field to account for 401(k) or HSA contributions.
