How much is overtime worth after tax?

Overtime is added on top of your normal salary and taxed at your marginal rate — the rate on the last pound, euro or dollar you earn. Once you cross a bracket, additional pay is taxed at the higher rate, so extra hours are worth less at the top than at the bottom.

Time-and-a-half (1.5×) is the most common overtime multiplier for hourly workers in the UK, Ireland and US. Some contracts pay 2× for weekends or public holidays. Salaried employees often aren't entitled to overtime unless it's in their contract.
