UK Overtime Pay Calculator

Our UK overtime calculator shows you exactly how much you will take home from overtime hours after income tax and National Insurance deductions. Many people are surprised to find that overtime pay is taxed at their marginal rate — so if you are a higher-rate taxpayer, you keep only 60p of every extra £1 earned (after 40% tax and 2% NI). Enter your annual salary, overtime hours, and overtime rate to see your gross overtime pay, tax deductions, and net take-home amount. This helps you decide whether overtime is worth your time and plan your finances accordingly.
