Piece-Rate Overtime Calculator
Standard Formula
Regular Rate = Total Piecework Pay ÷ Total Hours Worked; OT = Regular Rate × 0.5 × OT Hours
Because piecework pay already covers straight time for all hours worked, only the additional half-rate (0.5×) is owed for overtime.
How Piece-Rate Overtime Calculator Works?
The Piece-Rate Overtime Calculator works by dividing total piecework pay by total hours to find the regular rate, then adding 0.5× that rate for each overtime hour.
1Enter piecework earnings
Type total piece-rate pay for the workweek, $1,100.00 by default.
2Enter total hours
Add all hours worked, including non-productive time that is compensable. 46 by default.
3Read the regular rate
$1,100.00 ÷ 46 returns $23.91 per hour.
4Read total pay
6 overtime hours × $11.96 adds $71.74, for $1,171.74 gross.
Piece-Rate Overtime Calculator Formula
The Piece-Rate Overtime Calculator formula is OT Due = (Piecework Pay ÷ Total Hours) × 0.5 × Overtime Hours.
Regular rate
Regular Rate = Piecework Pay ÷ Total Hours
Half-time due
OT Due = Regular Rate × 0.5 × Max(0, Total Hours − 40)
Gross pay
Gross = Piecework Pay + OT Due
- Piecework Pay
- Pay earned per unit, crate, mile or job in the workweek.
- Total Hours
- All hours worked in the workweek.
- 0.5
- Only half-time is owed, since piece pay already covers straight time for every hour.
Worked example: 1,200 units at $0.75
Piecework Pay = 1,200 × $0.75 = $900.00 for 50 hours.
Regular Rate = $18.00. OT Due = $9.00 × 10 = $90.00. Gross = $990.00.

What is Piece-Rate Overtime Calculator?
A Piece-Rate Overtime Calculator is a tool that computes overtime for workers paid by the unit instead of by the hour.
29 CFR § 778.111 sets the method: total piece earnings divided by total hours gives the regular rate, and the employer owes an extra 0.5× that rate for hours over 40. Piece-rate pay is common in agriculture, garment work, trucking (per mile) and home installation.
California requires separate pay for rest periods and other non-productive time for piece-rate workers under Labor Code Section 226.2.
What are the uses of Piece-Rate Overtime Calculator?
There are 4 main uses of the Piece-Rate Overtime Calculator.
Farm and harvest crews
Workers paid per bin or per pound check overtime.
Per-mile drivers
Non-exempt local drivers compute overtime on mileage pay.
Installers and technicians
Workers paid per job verify the half-time owed.
Payroll compliance
Employers apply the 29 CFR § 778.111 method.
