What is the difference between marginal and effective tax rate? +

Your marginal rate is the rate on your last dollar of income — the “bracket” you’re in. Your effective rate is your total tax divided by total income. Because taxes are progressive, almost no one pays their full marginal rate on all income. For example, a single filer with $85,000 income is in the 22% bracket but only pays 22% on income above $48,475 — their effective federal rate is closer to 15–17%.
