Enter your clock-in time, clock-out time, and unpaid break to find your net hours worked.
Use 24-hour HH:MM format, e.g. 09:00 or 17:45.
Your result
8
Net hours worked
Gross hours (before break)8.5
Net time (h:m)8h 0m
AI explanation
Formula
Net hours = (clock out − clock in) − unpaid break, in hoursWorked example
9:00 to 17:30 with a 30-minute break
| Field | Value |
|---|---|
| Clock in (24-hour) | 09:00 |
| Clock out (24-hour) | 17:30 |
| Unpaid break (minutes) | 30 |
| Net hours worked | 8 |
| Gross hours (before break) | 8.5 |
| Net time (h:m) | 8h 0m |
Assumptions
- If clock-out is earlier than clock-in, an overnight shift is assumed (clock-out falls on the next day).
- Break time is subtracted from gross hours and cannot make net hours negative.
Frequently asked questions
How is an overnight shift handled?
If clock-out is earlier than clock-in (e.g. 22:00 to 06:00), the calculator assumes the shift crosses midnight and computes the duration accordingly.
I need to split worked hours into regular and overtime — is there a version for that?
Yes — see the Overtime Hours Calculator, which adds a standard-hours threshold and splits the total into regular and overtime portions.
Does this handle night shifts that cross midnight?
Yes — if the shift end time is earlier than the start time, it's automatically treated as falling on the following day.
