How to Calculate Labor Burden
Labor burden is the gap between what you pay an employee and what they actually cost you. This guide covers the formula, a step-by-step worked example, and the most common calculation mistakes. For a conceptual overview, see What Is Labor Burden?
The Formula
Total Employee Cost = Base Wages + All Employer Burden Items
Labor Burden Rate = (Total Cost − Base Wages) ÷ Base Wages × 100
True Hourly Cost = Total Annual Cost ÷ Annual Hours Worked
Worked Example
Employee earning $25/hr, working 2,080 hours per year ($52,000 base):
| Base wages | $52,000 |
| FICA (7.65%) | $3,978 |
| FUTA (~0.6% on $7k) | $42 |
| SUTA (3% estimate) | $1,560 |
| Workers' comp (2%) | $1,040 |
| Health insurance | $6,000 |
| Overhead allocation | $5,000 |
| Total annual cost | $69,620 |
Burden rate: 34% | True hourly cost: $33.47/hr
Why the Burden Rate Matters
If you price a job or set a bill rate using only the base wage, you will lose money on every hour worked. A 25–40% burden rate is typical for US employers — meaning a $25/hr employee actually costs $31–$35/hr to employ.
Common uses for the burden rate include:
- Setting a minimum labor rate for job estimates
- Comparing the true cost of W2 employees vs 1099 contractors
- Building a markup that covers all employment costs
- Workforce budgeting and headcount planning
- Project profitability analysis
Common Mistakes
- Using base wage as the cost in job pricing — ignores 25–40% of real cost
- Forgetting that SUTA and workers' comp vary widely — using average rates without checking actual rates for your industry
- Excluding overhead from the burden calculation, then finding that overhead costs are not recovered in bids
- Not accounting for non-billable time (training, downtime, holidays) when converting annual cost to hourly rate
Assumptions and Disclaimer
Burden rates vary by state, industry, employer experience rating, and benefit choices. SUTA rates for new employers are often higher than for established employers. Workers' compensation rates are set by state insurance bureaus and vary by job classification. These figures are for estimation only — consult a payroll professional or accountant for precise numbers.
