Show the working
- 1. Weekly net minutes = sum of enabled day (elapsed shift − break) = 2,250 minutes.
- 2. Entered weekly overtime threshold = 40 × 60 = 2,400 minutes.
- 3. Overtime = max(0, 2,250 − 2,400) = 0 minutes; regular = 2,250 minutes.
- 4. No pay estimate shown because hourly rate is 0.
Overnight shifts are supported by treating an earlier end clock as the following day.
Overtime classification uses only the weekly threshold and multiplier you enter. It does not implement jurisdiction-specific daily/double-time/7th-day rules.
Results do not round clock punches automatically; use the times and break deductions actually applicable to your record.

How to use this calculator
Add a day-by-day weekly schedule with unpaid breaks instead of assuming every day is identical. The result shows each day’s net time, weekly total, regular/overtime split under your entered weekly threshold and optional gross pay estimate.
Step-by-step
- Step 1
Enable the days worked and enter each start/end clock and unpaid break.
- Step 2
Enter the weekly overtime threshold; add an hourly rate/multiplier only if you want a pay estimate.
- Step 3
Review the daily table and weekly totals, then export CSV or use the shared calculation report.
How the result is calculated
Weekly net minutes = Σ(elapsed shift − break); weekly overtime = max(0, weekly net − entered threshold).

Common questions
Does an end time earlier than start mean an error?
No. It is treated as an overnight shift ending the following day.
Is overtime based on daily or weekly hours?
This owner applies only the weekly threshold you enter.
What if I only need total hours and not pay?
Leave hourly rate at zero. Hours and overtime classification still calculate, while pay estimates remain hidden.
