Multiple Shift Calculator Formula
The Multiple Shift Calculator formula is Daily Total = Shift 1 Hours + Shift 2 Hours, with daily overtime above 8 hours.
Daily total
Total = Shift 1 + Shift 2
Daily overtime
Daily OT = Max(0, Total − 8)
Day’s pay
Pay = Min(Total, 8) × Rate + Daily OT × Rate × 1.5
- Shift 1, Shift 2
- Hours from each shift in the same workday.
- Total
- Combined hours for the workday.
- Daily OT
- Hours above 8 in the workday.
Worked example: double shift at a hospital
Shift 1 = 7.5 hours, Shift 2 = 4 hours, rate $30.00.
Total = 11.5 hours. Pay = $240.00 + (3.5 × $45.00) = $397.50.
