Formula Used
Regular wage cost = base hourly wage × regular hours × weeks.
Overtime cost = base hourly wage × overtime multiplier × overtime hours × weeks.
Paid leave cost = paid leave hours × base hourly wage.
Gross wages = regular wage cost + overtime cost + paid leave cost + training cost.
Payroll taxes = gross wages × payroll tax percentage.
Insurance burden = gross wages × workers comp and liability percentages.
Subtotal = gross wages + payroll taxes + insurance burden + benefits and allowances.
Overhead cost = subtotal × overhead percentage.
Fully loaded annual cost = subtotal + overhead cost.
Productive hours = annual field hours × productive field percentage.
Loaded productive hourly cost = fully loaded annual cost ÷ productive hours.
Target rate = loaded productive hourly cost × profit markup × contingency factor.
How to Use This Calculator
Enter the worker wage, regular hours, overtime hours, and overtime multiplier. Add paid leave, holidays, sick days, and training time. Then enter payroll tax, workers compensation, liability, benefits, tools, vehicle, safety gear, and other labor burden costs.
Use the productivity percentage to adjust paid hours into usable field hours. Enter crew size to estimate annual crew cost. Enter project productive crew-hours to estimate project labor cost and bid amount. Press the calculate button. The result appears above the form.

Understanding Fully Loaded Labor Cost
Fully loaded labor cost shows the real price of one worker hour. It starts with wages. Then it adds payroll taxes, insurance, benefits, paid time off, tools, vehicles, supervision, and company overhead. In construction, this number is vital. A crew may look profitable on paper. Yet hidden burden can erase the margin.
Why This Cost Matters
Bid mistakes often begin with labor. Material prices are easier to quote. Labor changes with overtime, job conditions, safety risk, and crew productivity. A loaded rate helps the estimator compare field cost with the selling rate. It also helps owners understand why a low wage is not the full cost.
Main Cost Drivers
Payroll taxes are usually tied to taxable wages. Workers compensation often changes by trade. Roofing, framing, electrical, and excavation crews may carry different rates. Benefits can be annual costs. They must be converted into hourly amounts. Paid leave reduces productive hours. This means each billable hour must recover more cost.
Using the Result
The calculator separates base wages, overtime, employer taxes, insurance, benefits, allowance costs, and overhead. It then calculates paid labor cost and divides annual extras across productive hours. The final loaded cost per productive hour is useful for estimates. Add markup when you need a billable rate. Use a higher markup when project risk is high.
Construction Estimating Tips
Review each rate before every large bid. Insurance premiums, wage laws, and benefit plans can change. Use separate calculations for apprentices, journeymen, operators, and supervisors. Do not average every trade unless the crew mix is stable. Track actual hours after the job ends. Compare estimated loaded cost with payroll reports. This feedback improves the next estimate and protects cash flow.
Common Mistakes
Many contractors forget nonproductive time. Meetings, travel, training, cleanup, and rework still cost money. Some also forget small items like phone stipends and safety gear. These costs may seem minor. Across many workers, they become large. A detailed loaded labor cost keeps pricing honest and easier to explain. Keep inputs current. Use job-specific productive hours. Seasonal crews, union rules, remote sites, and weather delays can change the final rate. The best estimate treats labor as a complete business cost, not only a paycheck.
FAQs
What is fully loaded labor cost?
It is the complete cost of employing one worker. It includes wages, overtime, taxes, benefits, insurance, paid leave, tools, supervision, overhead, and other direct labor burden.
Why not use base wage only?
Base wage misses many employer costs. Construction bids based only on wages can underprice labor, reduce profit, and create cash flow problems after payroll and insurance bills arrive.
Should overtime be included?
Yes. Overtime changes labor cost quickly. Include expected overtime hours and the correct multiplier before pricing projects with compressed schedules.
What counts as labor burden?
Labor burden can include employer taxes, workers compensation, liability insurance, health benefits, retirement contributions, paid leave, uniforms, safety gear, phones, tools, vehicles, and training.
How do paid days off affect the rate?
Paid days off add cost without adding productive field hours. The same annual cost must be recovered from fewer working hours, so the loaded hourly rate rises.
Is loaded cost the same as billable rate?
No. Loaded cost is your internal cost. Billable rate usually adds profit, contingency, and risk allowance so the company can recover costs and earn margin.
How often should I update inputs?
Update inputs before major bids. Also review them when wages, insurance premiums, benefit plans, taxes, or productivity assumptions change.
Can this calculator support crew bids?
Yes. Enter crew size and project productive crew-hours. The calculator estimates annual crew cost, weekly crew cost, project labor cost, and target bid amount.
