Your effective tax rate is the average rate at which your entire income is taxed. It is calculated by dividing your total tax liability by your total taxable income. This rate gives you a more accurate picture of your actual tax burden than your marginal rate alone.

The marginal tax rate is the rate applied to your last dollar of income. Because the U.S. uses a progressive tax system, your effective rate is always lower than your marginal rate. Understanding this difference helps you make smarter decisions about deductions, retirement contributions, and income planning.
