Number of Journeyman Electricians
Number of Apprentices
Number of Foremen
Estimated Hours on Job
Journeyman Hourly Wage ($/hr)
Apprentice Hourly Wage ($/hr)
Foreman Hourly Wage ($/hr)

#### Formulas Used
Base Labor per Role: Base Labor = (Regular Hours × Hourly Wage) + (Overtime Hours × Hourly Wage × 1.5) Total Role Labor = Base Labor per Worker × Number of Workers
Total Base Labor: Total Base Labor = Foreman Labor Total + Journeyman Labor Total + Apprentice Labor Total
Labor Burden: Labor Burden = Total Base Labor × (Burden Rate / 100)
Burdened Labor Cost: Burdened Labor Cost = Total Base Labor + Labor Burden
Contractor Markup: Markup Amount = Burdened Labor Cost × (Markup % / 100)
Total Billable Labor: Total Billable Labor = Burdened Labor Cost + Markup Amount
Blended Rates: Total Man-Hours = Total Workers × Total Job Hours Blended Burdened Rate = Burdened Labor Cost / Total Man-Hours Blended Billable Rate = Total Billable Labor / Total Man-Hours
#### Assumptions & References
- Overtime is calculated at 1.5× the base hourly rate per the Fair Labor Standards Act (FLSA) for hours over 40/week; this calculator applies OT to all workers equally for simplicity.
- Default wage rates are based on U.S. Bureau of Labor Statistics (BLS) Occupational Employment Statistics for electricians (SOC 47-2111) and vary by task complexity.
- Labor burden (25–40%) typically includes: FICA (7.65%), FUTA/SUTA (~3%), workers' compensation insurance (~5–10%), general liability (~2–4%), health benefits (~5–8%), and paid time off accrual.
- Suggested burden rate of 32% is a common industry average for electrical contractors per NECA (National Electrical Contractors Association) labor cost guidelines.
- This calculator estimates direct labor costs only and does not include materials, equipment rental, permits, or subcontractor costs.
