How Contractors Calculate Labor Rates
A contractor's billable labor rate is not just the worker's wage. It must cover wages, employer taxes, benefits, overhead, and profit — or the business loses money on every hour billed.
The Building Blocks of a Labor Rate
A billable labor rate is built in layers:
Employee Wage
+ Labor Burden (taxes, insurance, benefits)
= Loaded Labor Cost
+ Overhead Allocation
= Break-Even Labor Rate
+ Profit Margin
= Billable Labor Rate
Step 1: Start With the Employee Wage
This is the hourly rate you pay the worker directly. For a subcontractor or 1099 worker, it is their hourly rate. For a W2 employee, the wage is only the starting point.
Example: $25/hr employee wage
Step 2: Add Labor Burden
For W2 employees, add employer payroll taxes (FICA 7.65%), unemployment taxes (FUTA + SUTA), workers' compensation, and any benefits. A 30% burden rate is common — but your actual rate depends on your industry, state, and benefits package.
Example: $25 × 1.30 = $32.50/hr loaded labor cost
See the How to Calculate Labor Burden guide for a full breakdown.
Step 3: Account for Non-Billable Time
Workers are not billable every hour they are paid. Training, travel, downtime, holidays, and administrative time are real costs with no associated revenue. If a worker is billable 80% of the time, you must recover 100% of their annual cost from 80% of their hours.
Adjusted Rate = Loaded Cost ÷ Billable Utilization Rate
Example: $32.50 ÷ 0.80 = $40.63/hr adjusted rate
Step 4: Add Overhead
Overhead includes business costs not tied directly to a job: office rent, vehicles, insurance, tools, software, and administrative staff. These must be covered by revenue — typically by adding an overhead allocation to each billable hour.
Example: $40.63 + $8.00 overhead allocation = $48.63/hr break-even rate
Step 5: Add Your Target Profit
The break-even rate covers all costs — but a business needs profit to survive and grow. Apply your target margin or markup to arrive at your billable labor rate.
Billable Rate = Break-Even Rate ÷ (1 − Target Margin)
Example at 20% margin: $48.63 ÷ 0.80 = $60.79/hr billable rate
Required markup and margin vary widely by trade, market, risk, and business structure. There is no single correct figure for all contractors.
Full Example Summary
| Employee wage | $25.00/hr |
| Labor burden (+30%) | $7.50/hr |
| Loaded labor cost | $32.50/hr |
| Utilization adjustment (÷80%) | $40.63/hr |
| Overhead allocation | $8.00/hr |
| Break-even rate | $48.63/hr |
| Profit (20% margin) | $12.16/hr |
| Billable labor rate | $60.79/hr |
These are illustrative figures. Your actual burden, utilization, overhead, and margin will differ.
Common Mistakes
- Using only the employee wage as the labor cost — ignores 25–60% of real cost
- Not accounting for non-billable time — causes under-recovery of wages and overhead
- Using industry average markup without verifying it covers your specific overhead
- Confusing markup and margin — a 25% markup is not a 25% profit margin
