What Is This Calculator?
An overtime pay calculator lets you instantly see how much extra money you will earn from working beyond your contracted hours. In the UK, there is no legal minimum overtime rate — but most employers pay time and a half (1.5×) or double time (2×) for overtime worked. The formula is straightforward: Extra Earnings = Hourly Rate × Overtime Multiplier × Overtime Hours. However, because overtime is taxed as regular income via PAYE, your gross extra earnings are not what hits your bank account.
When Should You Use This Tool?

- You want to work out whether taking optional overtime is worth it after tax

- You want to project the annual impact of regular overtime on your total income
