Weighted Overtime Calculator
Calculate FLSA-compliant blended regular rates, straight-time earnings, and overtime premiums for employees working multiple job rates.
When an employee works multiple roles at different hourly rates within the same workweek, calculating overtime pay isn't as simple as multiplying the overtime hours by 1.5 times their current rate. Under Fair Labor Standards Act (FLSA) regulations, employers must use the weighted average method (often called the blended rate method) to determine the employee's "regular rate of pay". This regular rate is computed by dividing the total straight-time earnings across all jobs (plus bonuses) by the total hours worked. Overtime hours are then compensated with an additional half-time (0.5) premium based on this blended rate. Failing to calculate overtime this way is one of the most common payroll compliance errors and can lead to costly Department of Labor audits and back-pay penalties. Use this calculator to generate instant, audit-ready weighted overtime breakdowns.
Total Gross Pay: $685.82
Straight-time pay represents $656.00 of the total. Overtime hours (4.0 hrs) contributed $29.82 in half-time premium pay.

Mathematical Formula Guide
1. Determine total earnings at straight-time rates:
Add up the earnings from all job rates: (32.0 hrs × $16.00) + (12.0 hrs × $12.00) = $656.00.
2. Calculate the blended regular rate of pay:
Divide total straight-time earnings ($656.00) by total hours worked (44.0 hrs):$656.00 ÷ 44.0 hours = $14.91/hr
3. Compute the overtime premium rate:
Multiply the blended regular rate ($14.91/hr) by 0.5 (half-time premium rate):$14.91 × 0.5 = $7.45/hr
4. Compute total overtime premium pay:
Multiply overtime hours (4.0 hrs) by the overtime premium rate ($7.45/hr):4.0 overtime hours × $7.45 = $29.82
Total Paycheck = Straight-time Subtotal ($656.00) + Overtime Premium Pay ($29.82) = $685.82.
How Weighted Overtime Works
The core concept behind weighted overtime is that an employee's "regular rate" of pay for a given week changes depending on the mix of work they perform. The FLSA mandates that the overtime rate must reflect this actual average rate of compensation.
Because the employee has already been compensated at their basic straight-time rate for all hours worked (including those over 40), the employer only needs to pay an additional **0.5 (half-time)** premium for the overtime hours to satisfy the 1.5x overtime requirement. This prevents double-paying the straight-time portion.
The FLSA Weighted Overtime Formula
The standard calculation process involves five logical steps:
Step-by-Step Example Calculation
Let's walk through a common scenario where an employee works two different shifts at a restaurant:
Assumptions:
- Line Cook shifts (Job 1): 32 hours at $16.00/hour
- Dishwasher shifts (Job 2): 12 hours at $12.00/hour
- Total Hours: 44 hours (4 overtime hours)
Calculations:
1. Straight-Time Earnings:
(32 hours × $16.00) + (12 hours × $12.00) = $512.00 + $144.00 = $656.002. Blended Regular Rate of Pay:
$656.00 straight-time pay ÷ 44 total hours = $14.91 per hour3. Overtime Premium:
$14.91 regular rate × 0.5 = $7.46 per hour4. Overtime Premium Pay:
4 overtime hours × $7.46 overtime premium rate = $29.845. Total Gross Pay:
$656.00 straight-time + $29.84 overtime premium = $685.84Non-Discretionary Bonuses & Commissions
A common mistake in payroll calculations is ignoring non-discretionary incentives. Non-discretionary bonuses (e.g., attendance rewards, production speed bonuses, sales commissions) are promised in advance and are tied to performance.
💡 Payroll Rule: Bonuses Shift the Blended Rate
If an employee earns a $100 performance bonus during the week, that $100 must be added to the straight-time earnings in Step 1. This raises the blended regular rate of pay, which in turn increases the overtime premium rate for that week. Failure to recalculate the overtime premium on top of bonuses is a frequent source of wage-and-hour lawsuits.
California Weighted Overtime Nuances
While federal FLSA rules apply to most of the United States, California has strict wage laws that alter how weighted overtime functions:
- Daily Overtime: California requires overtime for hours worked over 8 in a single day, or double-time for hours worked over 12 in a day. The weighted rate must apply to these daily premium hours.
- Flat-Sum Bonuses: Unlike commissions or production bonuses, California requires flat-sum bonuses to be divided by **straight-time hours only** (not total hours) when calculating the regular rate of pay, and the overtime multiplier for the bonus portion is 1.5, not 0.5.
Common Weighted Overtime Mistakes
❌ Using the Highest Rate
Paying overtime based only on the job rate during which the overtime hours occurred is sometimes done, but it can either overpay the employee (wasting company money) or underpay them (violating the FLSA), depending on which rate was active.
❌ Ignoring Travel Time Pay
If an employee travels between job sites, that travel time must be paid. If paid at a separate "travel rate," those hours and earnings must be included in the week's blended rate calculations.
Frequently Asked Questions
What is weighted overtime?
Weighted overtime (also known as blended overtime) is a method of calculating overtime pay for employees who work at two or more different job rates during a single workweek. Under the Fair Labor Standards Act (FLSA), you must determine the employee's regular rate as a weighted average of all rates paid before calculating the overtime premium.
How is the regular rate of pay calculated for multiple rates?
To calculate the regular rate of pay, add the straight-time earnings from all jobs worked during the week plus any non-discretionary bonuses. Then, divide this total straight-time earnings by the total number of hours worked across all jobs.
Do you pay overtime based on the job worked during the overtime hours?
Under the standard FLSA rules, overtime is based on the blended regular rate of pay for the week. However, FLSA Section 207(g)(2) allows an alternative method where overtime is paid based on the rate in effect during the overtime hours, provided there is an advance agreement with the employee and it meets specific conditions.
Must bonuses and commissions be included in the weighted overtime calculation?
Yes. Under the FLSA, all non-discretionary bonuses, commissions, and performance incentives must be included in the straight-time earnings when calculating the regular rate of pay. Discretionary bonuses (e.g., spontaneous holiday gifts) are excluded.
How does California calculate weighted overtime differently?
For multiple hourly rates, California generally aligns with the federal weighted average method. However, for flat-sum bonuses, California requires the bonus to be divided by straight-time hours only (not total hours) and multiplies the overtime rate by 1.5 instead of 0.5. California also mandates daily overtime (over 8 hours in a day) and double-time premiums.
