Labor Cost Calculator
Plan your construction cost project with our free labor cost calculator. Get precise measurements, material lists, and budgets.
Formula
Total Labor Cost = Workers x Hours/Day x Days x Hourly Wage x (1 + Burden Rate%)
The fully loaded labor rate is the base hourly wage multiplied by one plus the burden rate percentage. This rate accounts for all employer costs beyond the wage itself. Multiply the fully loaded rate by total man-hours (workers times hours per day times project days) to get the total labor cost for the project.
Worked Examples
Example 1: Framing Crew Weekly Cost
Problem: Calculate the weekly labor cost for a 5-person framing crew earning $40/hr, working 8 hours/day for 5 days, with a 30% burden rate.
Solution: Base daily wage = $40 x 8 = $320/worker\nBurden = $320 x 0.30 = $96/worker\nFully loaded = $416/worker/day\nDaily crew cost = $416 x 5 = $2,080\nWeekly = $2,080 x 5 = $10,400
Result: $10,400 weekly labor cost for the crew
Example 2: Concrete Pour Labor Estimate
Problem: Estimate labor for an 8-person concrete crew at $32/hr, 10 hours/day for 3 days, 40% burden.
Solution: Base daily = $32 x 10 = $320/worker\nBurden = $320 x 0.40 = $128\nFully loaded = $448/worker/day\nDaily crew = $448 x 8 = $3,584\nTotal = $3,584 x 3 = $10,752
Result: $10,752 total labor cost
Frequently Asked Questions
What is the labor burden rate in construction?
The labor burden rate represents the additional costs an employer pays on top of the base hourly wage. It typically includes payroll taxes (FICA, FUTA, SUTA), workers compensation insurance, general liability insurance, health insurance, retirement contributions, paid time off, and union benefits. In construction, the burden rate commonly ranges from 25% to 45% of the base wage, depending on the trade and location. Accurately calculating the burden rate is essential for profitable project bidding.
How do I estimate labor costs for a construction bid?
Start by determining the total man-hours needed using historical productivity rates for each task. Multiply the man-hours by the fully loaded labor rate, which includes the base wage plus the burden rate. Add a contingency of 5-10% for unexpected delays and rework. Break the estimate into phases or CSI divisions so you can track actual costs against the budget. Using crew-based estimating rather than individual rates provides more realistic projections for most construction activities.
What is the difference between direct and indirect labor costs?
Direct labor costs are wages paid to workers who physically perform the construction work, such as carpenters, electricians, and laborers on the job site. Indirect labor costs cover supervisory, administrative, and support roles that do not directly produce physical work but are necessary for the project, including project managers, safety officers, and office staff. Both must be accounted for in project pricing, with indirect labor often allocated as part of overhead rather than tied to specific work items.
How do overtime and shift differentials affect labor costs?
Overtime pay is typically 1.5 times the base hourly rate for hours exceeding 40 per week, and double time may apply for holidays or extended shifts. The burden rate still applies to overtime wages, making the true cost even higher. A worker earning $35 per hour at time-and-a-half actually costs the employer approximately $71-$78 per hour when burden is included. Shift differentials for night or weekend work add another 10-20% to the base rate. Scheduling to minimize overtime is one of the most effective ways to control labor costs.
