If the end time is earlier than the start time, enable “Ends the next day”. Estimated pay equals net decimal hours × hourly rate; this tool does not apply overtime laws or local payroll rules.

The calculation runs in your browser; time and pay values are not sent to the server.

How to use

This hours calculator finds the elapsed time between a start and end time, then subtracts any unpaid break. It handles shifts that cross midnight and reports the result as hours and minutes, decimal hours for time sheets or invoicing, and total minutes. You can optionally enter an hourly rate for a simple pay estimate without applying overtime laws or local payroll rules.

  1. Enter the start and end times.
  2. If the period finishes the following day, enable “Ends the next day”.
  3. Enter any unpaid break in minutes.
  4. Optionally add an hourly rate, then review net time, decimal hours and total minutes.

How it is calculated

Net hours = (end time − start time, adding 24h when needed) − break

Example

Example: from 09:00 to 17:30 is 8 hours 30 minutes gross. Subtracting a 30-minute break leaves 8 hours net = 8.00 decimal hours = 480 minutes. A 22:00 to 06:00 overnight shift with a 30-minute break leaves 7 hours 30 minutes = 7.50 decimal hours.

Important notes

Decimal hours are not clock notation: 8 hours 45 minutes equals 8.75 decimal hours, not 8.45. If you enter an hourly rate, the calculator simply multiplies net decimal hours by that rate; overtime premiums, taxes, allowances and statutory payroll rules are not included.

Frequently asked questions

How do I calculate hours between two times?

Subtract the start from the end. The calculator converts both times to minutes first, then returns hours/minutes, decimal hours and total minutes.

How do I calculate an overnight shift?

Enable “Ends the next day”. The end time is then treated as occurring on the following day rather than earlier on the same day.

What is the difference between 7:30 and 7.5 hours?

They are equal in this case because 30 minutes is half an hour. But 7:45 equals 7.75 decimal hours.

Can I deduct lunch or breaks?

Yes. Enter unpaid break minutes and they are subtracted from the gross time span.

Can this calculate pay?

Yes. Enter an hourly rate for a simple net-hours × rate estimate. Overtime premiums and payroll deductions are not applied.

Is this a weekly time-card calculator?

This page calculates one time span. A separate time-card calculator can combine multiple days and weekly totals.
