One Rule, Many Pay Structures
The FLSA overtime mandate is clear: non-exempt employees must receive at least 1.5 times their "regular rate of pay" for hours worked beyond 40 in a workweek. The challenge lies in determining that regular rate when workers are compensated through vastly different pay structures. An hourly worker's calculation is straightforward, but what about employees paid by piece rate, commission, day rate, or a combination of methods? Each structure requires a different approach to arrive at the correct overtime rate.
Getting this right matters enormously—both for workers seeking fair pay and employers aiming for FLSA compliance. Miscalculating the regular rate is one of the most common overtime violations, leading to class-action lawsuits that can cost companies millions of dollars. This guide covers the overtime calculation method for every major pay structure.
Hourly Pay: The Straightforward Baseline
For hourly employees with a single rate and no additional compensation, overtime is the simplest to calculate. The regular rate equals the hourly wage, and overtime is simply that rate multiplied by 1.5.
- Regular rate: $20/hour
- Overtime rate: $20 × 1.5 = $30/hour
- 45-hour week: (40 × $20) + (5 × $30) = $800 + $150 = $950
However, most hourly workers receive some form of additional compensation—shift differentials, attendance bonuses, or longevity pay—that complicates this basic calculation. All non-excluded compensation must be folded into the regular rate before applying the 1.5 multiplier.
Multiple Hourly Rates
Some employees work different jobs for the same employer at different hourly rates within the same workweek. In these cases, the FLSA provides two methods for calculating overtime:
Method 1: Weighted Average (Default)
Total all earnings at all rates for the week, then divide by total hours to find the weighted average regular rate.
Total straight-time earnings: (25 × $18) + (20 × $22) = $450 + $440 = $890
Weighted regular rate: $890 ÷ 45 = $19.78/hour
Overtime premium: $19.78 × 0.5 = $9.89/hour
Overtime pay: 5 hours × $9.89 = $49.44
Total: $890 + $49.44 = $939.44
Method 2: Rate in Effect (Employer Option)
If the employer and employee agree in advance, overtime can be paid at 1.5 times the rate that was in effect when the overtime hours were actually worked. Using Carlos's example, if the overtime occurred during forklift operation, the overtime rate would be $22 × 1.5 = $33/hour, yielding 5 × $33 = $165 in overtime. This method can result in either higher or lower overtime pay depending on which rate applies during overtime hours.
Salaried Non-Exempt Employees
Non-exempt salaried workers must receive overtime, and their regular rate is derived from their salary. The standard conversion assumes the salary covers 40 hours:
- Weekly salary: $900
- Regular rate: $900 ÷ 40 = $22.50/hour
- Overtime rate: $22.50 × 1.5 = $33.75/hour
Some salaried positions compensate for a fixed schedule exceeding 40 hours. If the salary explicitly covers 45 hours, the calculation changes: $900 ÷ 45 = $20/hour regular rate, with overtime owed at $20 × 0.5 = $10/hour extra for the 5 built-in overtime hours, totaling $900 + $50 = $950.
Piece-Rate Workers
Piece-rate employees are paid based on units produced rather than time spent. Their overtime calculation requires converting total piece-rate earnings into a per-hour regular rate for the specific week in question.
Two Methods for Piece-Rate Overtime
- Regular method: Divide total piece-rate earnings by total hours worked to find the regular rate. Multiply by 0.5 for the overtime premium per hour. The straight-time component is already included in the piece-rate earnings.
- Piece-rate with overtime by the piece: Pay 1.5 times the per-piece rate for pieces produced during overtime hours. This requires tracking which pieces were made during regular versus overtime hours.
Example using the regular method: A garment worker earns $0.50 per piece and produces 1,000 pieces in a 48-hour week. Total piece-rate earnings: $500. Regular rate: $500 ÷ 48 = $10.42/hour. Overtime premium: $10.42 × 0.5 = $5.21/hour. Total overtime pay: 8 × $5.21 = $41.67. Total weekly pay: $500 + $41.67 = $541.67.
Commission-Based Pay
Employees paid wholly or partly by commission face some of the most complex overtime calculations. The method depends on when commissions can be computed and allocated:
Commissions Computed Weekly
When commissions are calculated each week, they're simply added to other earnings for that week to determine the regular rate. For example, a sales associate who earns $12/hour base plus $200 in weekly commissions and works 44 hours:
- Total straight-time earnings: (44 × $12) + $200 = $528 + $200 = $728
- Regular rate: $728 ÷ 44 = $16.55/hour
- Overtime premium: $16.55 × 0.5 = $8.27/hour
- Total overtime: 4 × $8.27 = $33.09
- Total pay: $728 + $33.09 = $761.09
Deferred Commissions
When commissions span multiple weeks (monthly or quarterly), employers may temporarily disregard them for overtime purposes and then retroactively adjust overtime when the commission is finally computed. The employer must go back and recalculate the regular rate for each workweek affected by the commission and pay any additional overtime premium owed.
"When the calculation of the commission cannot be completed until some time after the regular pay day, the employer may disregard the commission in computing the regular rate until the amount can be ascertained. The additional compensation must then be apportioned back over the workweeks of the period during which it was earned." — 29 CFR § 778.120
Day-Rate and Job-Rate Workers
Some workers are paid a flat daily rate or a flat rate per job, regardless of hours worked. For overtime purposes, the regular rate is determined by dividing the total earnings by total hours worked in the workweek.
For example, a construction worker paid $250 per day works five 10-hour days (50 hours): Total earnings: 5 × $250 = $1,250. Regular rate: $1,250 ÷ 50 = $25/hour. Overtime premium: $25 × 0.5 = $12.50/hour for 10 overtime hours = $125. Total pay: $1,250 + $125 = $1,375.
Tipped Employees
Tipped workers present another variation. Employers may take a tip credit, paying a direct cash wage as low as $2.13/hour (federally), with tips making up the difference to the full minimum wage. For overtime, the regular rate is the full minimum wage (not just the cash wage), and the overtime rate is 1.5 times that amount, minus the tip credit.
