How Is Federal Income Tax Estimated?
Tax = Σ (taxable_income_in_bracket × bracket_rate)
Variable Definitions
- Taxable Income
- Gross income minus standard deduction and other deductions
- Brackets
- 2024 federal marginal tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%)
- Effective Rate
- Total tax ÷ gross income × 100%
💡 Federal income tax in the US is progressive — only income within each bracket is taxed at that bracket's rate. This calculator uses 2024 tax year brackets. State income taxes are not included.

For 2024, the standard deduction is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for heads of household. If your itemized deductions (mortgage interest, charitable giving, state/local taxes, etc.) exceed the standard deduction, it may benefit you to itemize.
Your marginal rate is the rate applied to your last dollar of income — the highest bracket you fall into. Your effective rate is your total tax divided by your total income — your true overall tax burden. Because the US tax system is progressive, your effective rate will always be lower than your marginal rate.
