How to use the hours calculator

  1. Enter the start and end time for a day. On a phone, tap the box to pick a time.
  2. Add any unpaid break in minutes, for example 30 for a lunch break.
  3. Press + Add a day to add another shift. It copies the times from the day above, so you only change what is different.
  4. Read your total in hours and minutes, and in decimal hours for payroll. Add your hourly rate to estimate your pay.

Frequently asked questions

How do I calculate hours worked?

Subtract the start time from the end time, then take off any unpaid break. For example, 9:00 AM to 5:30 PM is 8 hours 30 minutes, and with a 30 minute lunch that leaves 8 hours.

What about night shifts that go past midnight?

Just enter the times as they are. If the end time is earlier than the start time, the calculator assumes the shift ended the next day. 10:00 PM to 6:00 AM counts as 8 hours.

What are decimal hours?

Payroll systems often want hours as a decimal number instead of hours and minutes. 7 hours 45 minutes is 7.75 hours, because 45 minutes is three quarters of an hour. The calculator shows both.

Can I work out my pay?

Yes. Enter your hourly rate and the calculator multiplies it by the total hours. It does not include overtime rates or tax, so treat it as an estimate.
