Adding up a week of start and finish times is fiddly. Our Time Card Calculator does it for you and works out your pay.
How to use the calculator (Time Card Calculator)
- For each day you worked, enter your start and finish times and any unpaid break.
- Enter your hourly rate to see your pay.
- If you get a higher rate for overtime, enter when it starts and the multiplier, such as 1.5 for time and a half.
Leave days you didn't work blank. Overnight shifts are handled automatically.
How it works
For each day: finish − start − unpaid break. The days are added up and shown in hours and minutes and in decimal hours, which is what most payroll systems use.
A worked example
With the calculator's default settings, Monday to Friday, 9:00 to 17:30 with a 30-minute break, is 8 hours a day, or 40 hours a week. At the National Living Wage of £12.71 an hour, that's £508.40 before tax.
Your rights
- Most workers aged 21 and over must get at least the National Living Wage.
- You can't usually be made to work more than 48 hours a week on average, unless you choose to opt out.
- If you work more than 6 hours, you're entitled to a 20-minute break.
