Multi-Rate Pay Calculator
WorkHourHub.com's Multi-Rate Pay Calculator computes weighted average blended overtime rates for employees working multiple jobs or pay rates under 29 CFR § 778.115.
🔀 Multi-Rate / Dual Pay Rate Calculator (FLSA Blended)
Essential Overview & Quick Rules
- WorkHourHub.com's Multi-Rate Pay Calculator computes weighted average regular rates of pay per FLSA 29 CFR § 778.115.
- When an employee works at two or more different pay rates in one workweek, overtime cannot be calculated on the higher or lower rate arbitrarily.
- The regular rate is the weighted average: total straight-time earnings divided by total hours worked in the workweek.
- Overtime is compensated with an additional 0.5× the weighted regular rate for all hours exceeding 40.0.

How Do You Calculate Blended Overtime for Dual Pay Rates Under Federal Law?
To calculate blended overtime for employees working at two or more pay rates in a single workweek, calculate straight-time earnings for each job, sum total straight-time earnings, divide by total weekly hours to establish the weighted regular rate of pay, and pay an additional 0.5× the weighted rate for all overtime hours over 40.0.
Which Statutory Regulation Mandates Weighted Average Overtime?
Under the Code of Federal Regulations (29 CFR § 778.115), when an employee in a single workweek works at two or more different types of work for which different hourly rates have been established, their regular rate for overtime purposes is the weighted average of such rates.
What Is the Mathematical Formula for Multi-Rate Blended Overtime?
Blended overtime calculation follows The Weighted Average Regular Rate Equation:
Total Straight-Time Earnings = (Hours_1 × Rate_1) + (Hours_2 × Rate_2) + ...
Weighted Regular Rate of Pay = Total Straight-Time Earnings ÷ Total Hours Worked
Overtime Premium Rate = Weighted Regular Rate of Pay × 0.5
Total Overtime Premium Pay = Overtime Hours (Hours - 40.0) × Overtime Premium Rate
Total Gross Weekly Pay = Total Straight-Time Earnings + Total Overtime Premium Pay
Worked Example: How Do You Calculate Pay for 30h @ $20/hr and 20h @ $30/hr?
Consider an employee who works 30.0 hours as a Clerk ($20.00/hr) and 20.0 hours as a Supervisor ($30.00/hr) for 50.0 total weekly hours (10 overtime hours):
Step 1 – Calculate Total Straight-Time Earnings
Job 1 Straight-Time = 30.0 × $20.00 = $600.00.
Job 2 Straight-Time = 20.0 × $30.00 = $600.00.
Total Straight-Time Earnings = $600.00 + $600.00 = $1,200.00.
Step 2 – Calculate the Weighted Regular Rate of Pay
Weighted Regular Rate = $1,200.00 ÷ 50.0 total hours = $24.00 per hour.
Step 3 – Compute the Additional 0.5x Overtime Premium
Overtime Premium Rate = $24.00 × 0.5 = $12.00 per hour.
Overtime Premium Pay = 10.0 overtime hours × $12.00 = $120.00.
Step 4 – Sum Total Gross Weekly Wages
Total Gross Pay = $1,200.00 (straight-time) + $120.00 (overtime premium) = $1,320.00.
Why Is Arbitrary Overtime Rate Selection a Severe Legal Liability?
Paying overtime solely based on the rate in effect when overtime occurred is generally unlawful unless established by prior agreement under 29 CFR § 778.419. Using our Multi-Rate Pay Calculator ensures strict federal compliance. For single-rate overtime, use our Overtime Pay Calculator or estimate gross wages with the Gross Pay Calculator.

❓ Frequently Asked Questions (PAA)
Authoritative answers to common questions regarding work hours, break rules, overtime laws, and payroll math.
What is blended overtime pay under federal law? ▾
Blended overtime is the statutory FLSA method under 29 CFR § 778.115 for calculating overtime when an employee works at two or more different pay rates in the same workweek.
How do you find the weighted regular rate of pay? ▾
Divide total straight-time earnings from all jobs by total hours worked in the workweek. For example, $1,200 total earnings divided by 50 hours equals a $24.00 weighted regular rate.
Why is the overtime multiplier 0.5x instead of 1.5x in blended calculations? ▾
Because all 50 hours have already been paid at 1.0× straight-time in the first calculation step, adding an extra 0.5× for the 10 overtime hours achieves the full 1.5× requirement.
Can an employer pay overtime based on the rate of the job performed during overtime? ▾
Only if there was an explicit agreement before the work was performed pursuant to FLSA Section 7(g)(2) and 29 CFR § 778.419; otherwise, the weighted average method is legally required.
Do shift differentials require blended overtime calculations? ▾
Yes. Shift differentials represent a second pay rate and must be factored into the weighted regular rate under 29 CFR § 778.207.
