What Is Marginal Tax Rate?
Marginal tax rates are widely misunderstood. Many people fear earning more because they think ALL their income gets taxed at the higher rate — it does not.
About This Calculator
Your marginal tax rate is the rate applied to your next dollar of income. Because of progressive brackets, it is always higher than your overall (effective) tax rate.
Real-world example: In the 24% bracket, every extra $100 you earn keeps $76 — but most of your income was taxed at lower rates.
