How is overtime pay calculated?

Overtime is normally paid at a multiple of your standard hourly rate — time and a half (1.5×) and double time (2×) are the most common arrangements, though the exact rate depends entirely on your contract, since UK law doesn't mandate a specific overtime premium. What is guaranteed is that your average pay across the pay period, including overtime hours, must still meet at least the National Minimum Wage. This calculator applies your chosen multiplier to just the overtime hours and adds it to your normal pay for the period.

Frequently asked questions

What does time and a half mean?

It means overtime hours are paid at 1.5 times your normal hourly rate — so £12/hour becomes £18/hour for those hours. Double time means twice the normal rate.

Is overtime pay a legal requirement in the UK?

There's no automatic legal right to overtime pay itself — it depends on your contract. What is guaranteed is that your average pay across a pay period must still meet at least the National Minimum Wage for all hours worked, including overtime.

How do I work out my hourly rate from an annual salary?

Divide your annual salary by your total working hours for the year — typically around 52 weeks × your contracted weekly hours. This calculator lets you enter an hourly rate directly if you already know it.
