How It Works
How to Calculate Labor Costs
Formula
Total Labor Cost = Hourly Rate x Hours x Number of Workers
Labor is typically the largest expense for service businesses and contractors. Accurate labor cost estimation is critical for profitable bidding and project management.
Worked Example
3 workers at $35/hour for 40 hours each.
- 01Cost per worker = $35 x 40 = $1,400
- 02Total labor cost = $1,400 x 3 = $4,200
- 03Daily labor cost (8hr day) = $35 x 8 x 3 = $840
Frequently Asked Questions
How do I estimate labor costs for a project?
Estimate the total hours needed, multiply by the hourly rate, and multiply by the number of workers. Add 10-15% buffer for unexpected delays.
Should I include benefits in the hourly rate?
For true cost analysis, yes. The fully burdened labor rate includes wages plus taxes, insurance, benefits, and workers comp. This is typically 25-40% above the base wage.
