People mix up two very different numbers. Your marginal tax rate is the bracket your nextdollar lands in — the “I'm in the 22% bracket” number. Your effective tax rate is what you actuallypay on average across all your income, and it's always lower because the U.S. taxes income in progressive bands. This calculator shows both at once for 2026, including federal income tax, Social Security, Medicare, and state tax. To see the full paycheck picture with deductions, use the paycheck calculator.
