Your effective tax rate is the average rate at which your total income is taxed. It is calculated by dividing your total federal tax owed by your gross income and expressing the result as a percentage. Unlike your marginal rate, the effective rate reflects your true overall tax burden. See also our calculate Corporation Tax Estimated Annual Tax Savings (S Corp).
Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you fall into. Your effective tax rate is the weighted average across all brackets. Because the U.S. uses a progressive system, most people pay a lower effective rate than their marginal rate.
The 2025 federal tax brackets have seven rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each rate only applies to the income within that bracket range — not to your total income. The bracket thresholds differ based on your filing status.
For 2025, the standard deduction is $15,000 for Single filers, $30,000 for Married Filing Jointly, $15,000 for Married Filing Separately, and $22,500 for Head of Household. Choosing the higher of the standard or itemized deduction reduces your taxable income.

You should choose whichever deduction is larger. If your total qualifying expenses — such as mortgage interest, state taxes, and charitable donations — exceed the standard deduction for your filing status, itemizing may lower your tax bill. Most filers benefit from the standard deduction.
Tax deductions reduce your taxable income, while tax credits directly reduce the amount of tax you owe dollar-for-dollar. A $1,000 credit saves you exactly $1,000 in taxes, whereas a $1,000 deduction saves you only the amount multiplied by your marginal rate.
This calculator focuses on federal income tax only. State income tax rates vary widely — from 0% in states like Texas and Florida to over 13% in California. For a full picture of your tax burden, you would need to add your state's income tax separately.
Other taxable income includes freelance or self-employment earnings, rental income, capital gains, dividends, alimony received (for pre-2019 agreements), and other sources beyond your primary W-2 wages. Including these gives you a more accurate effective tax rate.
