Hours Calculator

Work hours between two times, with unpaid breaks and optional pay.

Enter when work started, when it ended, and how many unpaid break minutes to subtract. The result shows normal hours-and-minutes plus decimal hours for payroll. If you add an hourly rate, it also estimates regular and overtime pay.

Fields marked optional can be skipped; results update as you type

Use the clock time when paid work began.

If this is earlier than the start time, the calculator treats it as an overnight shift.

Enter minutes not counted as work, such as 30 for lunch.

How to use

  1. Enter the time work started and the time work ended.
  2. Enter unpaid break minutes, such as 30 for a half-hour lunch.
  3. Optional: add your hourly rate if you want a pay estimate.

Examples

9:00 to 17:30 with 30-min break
8:00 worked = 8.00 hours

Before you trust the result

Check the inputs that matter most: dates, rates, units, costs, and any optional fields you skipped. A calculator can only work with the numbers entered here, so use the result as a decision check rather than a final answer when money, health, tax, legal, or safety consequences are involved.

If the result feels surprising, change one input at a time and watch which number moves. That usually shows the real lever behind the decision.

Frequently asked questions

› Does it handle overnight shifts?

Yes. If the end time is earlier than the start, it assumes you crossed midnight.

› Is overtime calculated? Trust & accuracy

Yes, if you open the optional pay section. Enter the hourly rate, the number of worked hours before overtime begins, and the overtime pay rate such as 1.5 for time-and-a-half.

› How do I calculate a 7.6-hour day? How-to

A 7.6-hour workday is 7 hours and 36 minutes (0.6 × 60 = 36). Decimal hours after the point convert to minutes by multiplying by 60: 7.25 h = 7h 15m, 7.5 h = 7h 30m, 7.75 h = 7h 45m. This calculator shows both decimal hours and HH:MM form so you can read whichever you need.
