Overtime Pay Calculator
Enter your hourly rate, normal hours and overtime hours, pick the overtime multiplier (1.5×, 2× or custom), and see the overtime pay and your total for the week.
How it works
Overtime pay = hourly rate × multiplier × overtime hours. At £14/hour, 6 hours at time-and-a-half is 14 × 1.5 × 6 = £126.
Total pay = (rate × normal hours) + overtime pay. A 37.5-hour week at £14 plus those 6 overtime hours comes to £525 + £126 = £651 before tax.
There is no statutory overtime rate in the UK — the multiplier is whatever your contract says, and employers don’t have to offer premium rates at all. The only legal floor is that your AVERAGE pay across all hours worked must not drop below the National Minimum Wage.
FAQ
Is my employer legally required to pay time-and-a-half?
No. UK law sets no overtime premium — your contract determines whether overtime is paid at a higher rate, at your normal rate, taken as time off in lieu (TOIL), or is unpaid for salaried staff. The legal backstop is the National Minimum Wage: total pay divided by total hours worked in the pay reference period must not fall below it.
What is time-and-a-half and double time?
Time-and-a-half means 1.5× your basic hourly rate (£14 becomes £21 per overtime hour) and is common for weekend or late shifts where a premium is offered. Double time (2×) is rarer and typically reserved for bank holidays or unsociable call-outs. Check your contract or staff handbook for which hours attract which multiplier.
Is overtime taxed more than normal pay?
No — overtime is added to your gross pay and taxed through PAYE at exactly the same rates as the rest of your income. It can feel more heavily taxed because the extra income sits at the top of your pay, so it may be taxed at your highest marginal rate, and a big overtime month can temporarily push more of that month’s pay into a higher band until PAYE evens out.
