Time and a half calculator (UK)
Quick answer: time and a half is your normal hourly rate × 1.5. On £20 an hour that is £30 an hour, so 6 hours is £180. Enter your own rate below, or a day rate, to see the overtime rate and the pay.
How to work out time and a half
- Find your hourly rate. On a day rate, divide by the hours in a standard day: £160 ÷ 8 = £20.
- Multiply by 1.5: £20 × 1.5 = £30 an hour.
- Multiply by the overtime hours: £30 × 6 = £180.

Worked example: a week with overtime
A contractor on £180 a day (8-hour day, so £22.50 an hour) works 5 normal days and 6 extra hours on Saturday at time and a half, the rate agreed with this client (the BillMyWeek default Saturday multiplier is ×1.25, and Sunday ×1.5; both are editable). Normal pay: 5 × £180 = £900. Overtime rate: £22.50 × 1.5 = £33.75. Overtime pay: 6 × £33.75 = £202.50. Total before tax: £1,102.50. Show normal and overtime on separate invoice lines so the client can match them to the timesheet.
Is time and a half a legal right?
No. GOV.UK says employers do not have to pay workers for overtime, although your average pay for the total hours you work must not fall below the National Minimum Wage. Your employment contract will usually set out any overtime rate. Self-employed contractors agree overtime rates with the client and put them on the invoice. See overtime on invoices.
