How is overtime pay calculated?
Overtime pay is your normal hourly rate multiplied by an overtime rate, then multiplied by the number of overtime hours you work. The most common UK overtime rate is time and a half (×1.5), with double time (×2) often paid for Sundays and bank holidays. There is no legal requirement for employers to pay extra for overtime — it depends on your contract — but when they do, this is how it adds up.
If you earn £14 an hour and work 6 hours of overtime at time and a half, your overtime rate is £21 an hour, so you earn an extra £126 on top of your normal pay (before tax).
Common overtime rates
| Rate name | Multiplier | On £14/hr |
|---|---|---|
| Same rate | ×1 | £14.00 |
| Time and a quarter | ×1.25 | £17.50 |
| Time and a third | ×1.33 | £18.62 |
| Time and a half | ×1.5 | £21.00 |
| Double time | ×2 | £28.00 |
Overtime, minimum wage and tax
Employers do not have to pay a premium for overtime, but your average pay must not fall below the National Minimum Wage for your total hours. Overtime counts as earnings, so income tax and National Insurance are deducted as normal — the figures here are before tax. Overtime can also affect things like holiday pay, since regular overtime should be included in your statutory holiday pay.
Check your contract
Your overtime rate, and whether overtime is paid at all, is set by your employment contract. Some employers offer time off in lieu (TOIL) instead of extra pay. To see how your hourly rate translates into a yearly salary, try our hourly wage calculator. For the legal minimum you must earn per hour, see our minimum wage calculator. The rules on pay are explained on GOV.UK.
Frequently asked questions
How do I calculate overtime pay?
Multiply your normal hourly rate by the overtime rate (such as 1.5 for time and a half), then multiply by the number of overtime hours. For example, £14 an hour at time and a half is £21 an hour for each overtime hour worked.
What is time and a half?
Time and a half means you are paid 1.5 times your normal hourly rate for overtime. If your normal rate is £14, time and a half is £21 per hour. Double time means twice your rate, so £28 per hour.
Does my employer have to pay overtime?
No. UK law does not require employers to pay extra for overtime. Whether you get paid, and at what rate, depends on your contract. However, your average pay must not drop below the National Minimum Wage.
Is overtime taxed differently?
No. Overtime is taxed at your normal income tax and National Insurance rates. It can push more of your pay into a higher tax band in that period, but there is no special higher tax rate just for overtime.
Does overtime count towards holiday pay?
Regular overtime should be included when working out your statutory holiday pay, based on your average earnings over the previous 52 weeks. Genuinely occasional one-off overtime may not be included.
