Understanding Piece Rate Overtime Calculations

In many industries, workers are paid by the "piece" rather than by the hour. However, the Fair Labor Standards Act (FLSA) still requires that these employees receive overtime pay for any hours worked beyond 40 in a workweek. Calculating this is often more complex than a standard hourly wage calculation.

How the Calculation Works

The standard method for calculating overtime for piece-rate employees involves determining the "Regular Rate of Pay" for that specific workweek. This is done by taking the total piecework earnings and dividing them by the total number of hours worked (including overtime hours).

  • Step 1: Multiply total pieces produced by the rate per piece to find total straight-time earnings.
  • Step 2: Divide total straight-time earnings by total hours worked to find the Regular Rate.
  • Step 3: Since the piece rate has already paid the "straight-time" for the overtime hours, the employer owes an additional 0.5 (half-time) premium for every overtime hour worked.
  • Step 4: Add the overtime premium to the straight-time earnings for the final total.

Realistic Example

Suppose an employee, Sarah, works in a garment factory. She earns $2.00 per shirt completed.

Sarah's Week:
  • Shirts Produced: 300
  • Total Hours Worked: 50
  • Overtime Hours: 10
The Math:
  1. Straight Pay: 300 shirts × $2.00 = $600.00
  2. Regular Rate: $600 / 50 hours = $12.00/hour
  3. OT Premium Rate: $12.00 × 0.5 = $6.00/hour
  4. OT Premium Pay: $6.00 × 10 hours = $60.00
  5. Total Weekly Gross: $600 + $60 = $660.00

Important FLSA Considerations

It is crucial to note that the resulting "Regular Rate of Pay" must never fall below the federal or state minimum wage. If the pieces-per-hour rate results in a wage lower than the minimum, the employer is required to make up the difference before calculating overtime premiums.
