Enter your normal hourly rate, your normal hours and your overtime hours, then pick an overtime multiplier to see your overtime pay and total pay for the week.
Results are estimates for planning. Check the figures before you make a financial or health decision.
How the Overtime pay works
The calculation is straightforward. Normal pay is your hourly rate multiplied by your normal hours. The overtime rate is your hourly rate multiplied by the overtime multiplier you select: time and a quarter (×1.25), time and a half (×1.5), double time (×2), two and a half times (×2.5) or triple time (×3).
Overtime pay is that overtime rate multiplied by the overtime hours. Total pay for the week is normal pay plus overtime pay.
The results show the overtime rate per hour, normal pay, overtime pay and the share of the total that comes from overtime. All figures are gross, before tax and National Insurance. The calculator works on a single week and does not add bonuses, shift allowances or holiday pay. In the UK there is no general legal right to a higher rate for overtime, so the multiplier depends on your contract or workplace agreement.
Worked example
Using the default values in the calculator above:
| Input | Value |
|---|---|
| Normal hourly rate | £14 |
| Normal hours | 40 hours |
| Overtime hours | 8 hours |
| Overtime rate | Time and a half (x1.5) |
Total pay for the week: £728.00
| Overtime rate per hour | £21.00 |
|---|---|
| Normal pay | £560.00 |
| Overtime pay | £168.00 |
| Share from overtime | 23.1% |
Tips and common mistakes
Check your contract or staff handbook for the exact multiplier and for when overtime starts. Some employers pay it only after a set number of hours, or only on certain days, so enter normal hours and overtime hours to match.
Overtime is taxed as normal income, so it can be taxed at a higher rate than you expect if it pushes you over a threshold. Use the UK take-home pay calculator to estimate the effect on your pay after tax. See Hourly rate to salary, and how to work out overtime for more.
Frequently asked questions
Do I have a legal right to time and a half?
In the UK there is no general legal right to a higher overtime rate. It depends on your contract or workplace agreement.
Is the result before or after tax?
Before tax. It is gross pay, so deductions such as income tax and National Insurance are not taken off.
Can I use it for a month instead of a week?
The tool is built for one week. For a month, you can enter the total hours for the month, but check that your normal hours match that period.
