Weighted Average Overtime: Calculating Blended Rates
Working two different jobs at different rates in the same week? Learn how the FLSA weighted average blended rate method applies to your overtime.

Many employees in healthcare, hospitality, manufacturing, and construction work in dual roles during the same week. For instance, a nurse might work some hours as a registered nurse (RN) and other hours in a charge nurse role at a different pay rate.
Under the Fair Labor Standards Act (FLSA), when an employee works at two or more different hourly rates in a single workweek, calculating overtime is not as simple as multiplying the rate in effect during the overtime hours by 1.5. Instead, employers must use the weighted average method (also called the blended rate method) to find the regular rate of pay.
To compute this correctly and prevent wage errors, using a weighted average overtime calculator or a specialized blended overtime rate calculator is highly recommended.
What is the Weighted Average Overtime Method?
The weighted average method finds a single "blended" hourly rate for the week. This rate is computed by dividing the total straight-time earnings from all jobs by the total hours worked across all jobs.
Once this blended rate is determined, the employer owes the worker an additional **0.5× the blended rate** for all hours worked over 40. This is because the employee has already been paid the straight-time (1.0x) portion of their wages for all hours worked.
The Weighted Average Calculation Formula
- Find Job A Earnings: Hours worked in Job A × Hourly Rate A
- Find Job B Earnings: Hours worked in Job B × Hourly Rate B
- Calculate Total Straight-Time Earnings: Job A Earnings + Job B Earnings
- Calculate Total Hours Worked: Hours A + Hours B
- Determine the Blended Regular Rate: Total Earnings ÷ Total Hours
- Compute Overtime Premium Owed: Overtime Hours × (Blended Rate × 0.5)
Worked Example: Dual Rates in Healthcare
Let's look at an example. James works at an assisted living facility. During a 45-hour workweek, he works:
- **30 hours** as an Aide at **$18.00/hour**
- **15 hours** as an Activities Coordinator at **$22.00/hour**
- James worked a total of **45 hours**, meaning he has **5 overtime hours**.
James's Wage Math:
- Earnings from Aide Shift: 30 hours × $18.00 = $540.00
- Earnings from Coordinator Shift: 15 hours × $22.00 = $330.00
- Total Straight-Time Earnings: $540.00 + $330.00 = **$870.00**
- Blended Regular Rate (RROP): $870.00 ÷ 45 hours = **$19.33 per hour**
- Overtime Premium Owed (0.5× RROP): $19.33 × 0.5 = **$9.67 per hour**
- Overtime Premium Earned: 5 overtime hours × $9.67 = **$48.35**
- James's Total Weekly Gross Pay: $870.00 (straight-time) + $48.35 (overtime premium) = **$918.35**
⚠️ Standard Error: Under standard rules, James's base overtime rate depends on this blended rate, not on which shift he happened to be working when he crossed the 40-hour threshold. Recomputing with incorrect rates is a classic payroll violation.
