Work Hours Calculator

Enter a shift start, finish, and unpaid break to calculate paid hours and minutes, total minutes, and decimal hours for timesheets or planning.

Shift inputs

Work hours formula

Paid work time = shift end - shift start - unpaid breaks; when end is earlier than start, the shift is treated as crossing midnight.

Overnight shifts

Automatically treats an earlier finish time as the following day.

Break deduction

Subtracts unpaid break minutes from elapsed shift time.

Decimal conversion

Shows the same paid duration as decimal hours for reporting.

How to calculate hours worked

Start with the elapsed time between clock-in and clock-out, then subtract unpaid meal or rest breaks. The result is shown in hours and minutes for readability and in decimal hours for timesheets, invoicing, and payroll systems. For example, 7 hours 30 minutes equals 7.50 decimal hours, while 7 hours 45 minutes equals 7.75.

If the end time is earlier than the start time, this calculator assumes the shift crosses midnight. It supports one continuous shift of less than 24 hours. Split shifts, paid breaks, rounding policies, and shifts longer than one day should be calculated in separate entries according to your employer policy.

Keep the original clock records when accuracy matters. This page provides a planning estimate and does not determine payroll compliance, break entitlement, or local employment-law requirements.

Frequently asked questions

How are work hours calculated?

The calculator subtracts start time from end time and then deducts the unpaid break.

Can it calculate an overnight shift?

Yes. If the end time is earlier than the start time, it assumes the shift ended the following day.

What are decimal hours?

Decimal hours express minutes as a fraction of an hour; 30 minutes is 0.50 and 45 minutes is 0.75.

Does this determine payroll pay?

No. Verify time-clock rounding, paid breaks, overtime, and payroll rules with your employer or applicable authority.
