Calculate your true fully burdened labor cost, including FLSA overtime pay, payroll taxes, and benefits loading.

Mathematical Audit

How Overtime Cost & Labor Burden Rate Are Calculated

Regular and overtime pay are calculated separately using the FLSA time-and-a-half rule, then both are grossed up by your labor burden rate to reflect payroll taxes, benefits, and workers' comp.

Regular Annual Pay = Hourly Rate × Regular Hours/Week × Weeks/Year
Overtime Pay = Hourly Rate × Overtime Multiplier × Overtime Hours/Week × Weeks/Year
Burdened Cost = Pay × (1 + Labor Burden %)
Fully Burdened Hourly Rate = Hourly Rate × (1 + Labor Burden %)
Fully Burdened Overtime Rate = Hourly Rate × Overtime Multiplier × (1 + Labor Burden %)

Under the FLSA, non-exempt employees must be paid at least 1.5x their regular rate for hours over 40 in a workweek. Labor burden (payroll taxes, benefits, workers' comp, and overhead) typically adds 25-40% on top of base wages, so burdened overtime cost is proportionally higher than burdened regular pay, not just 1.5x the base wage.

How to Use the Overtime Cost & Labor Burden Rate Calculator

1

Enter the hourly wage

Use the employee's base hourly rate before any burden or overtime multiplier is applied.

2

Enter regular and overtime hours per week

Regular hours are typically capped at 40 under FLSA; anything above that is overtime.

3

Set your labor burden percentage

Include payroll taxes, benefits, workers' comp, and overhead as a percentage of base wages; 25-40% is typical.

4

Adjust the overtime multiplier

Use 1.5 for standard time-and-a-half, or a higher figure for double-time or contractual premiums.

5

Review your fully burdened cost

See your true hourly cost for regular and overtime hours, plus your total annual burdened labor cost.

Real-World Scenario Example

"An employee earning $25/hour works 40 regular hours plus 8 overtime hours weekly for 52 weeks, with a 30% labor burden and standard 1.5x overtime."

Inputs

hourlyRate:25
regularHoursPerWeek:40
overtimeHoursPerWeek:8
weeksPerYear:52
burdenPercent:30

Result

A fully burdened regular rate of $32.50/hour and burdened overtime rate of $48.75/hour, totaling about $87,880 in annual burdened labor cost.
