What is burden rate?
Burden rate is the ratio of indirect labor-related costs to direct wages — the overhead that gets layered on top of every dollar paid in wages. It captures the employer-side costs that are real and recurring but do not appear on the employee's paycheck.
Paying someone $25 per hour does not mean that person costs $25 per hour to employ. After adding employer payroll taxes, benefits, workers' compensation, paid leave, and similar items, the true hourly cost is often $30–$35 or higher. Burden rate quantifies that gap and makes it usable for pricing, budgeting, and job costing.
The concept appears in construction bidding, service business pricing, manufacturing cost accounting, payroll budgeting, and any context where knowing the real cost of labor — not just the wage — is necessary to make sound decisions.
Burden rate formula
The core formula is:
Direct Wages = base wages or salary paid for productive work
Burden Rate = how much extra sits on top, per dollar of wages
To calculate the fully burdened labor cost and hourly rate:
Burden Cost per Hour = Total Burden Cost ÷ Labor Hours
Fully Burdened Hourly Rate = Fully Burdened Labor Cost ÷ Labor Hours

This is the default example from the calculator: direct wages $8,000 · payroll taxes $612 · benefits $980 · insurance $260 · PTO and other $348 · 320 labor hours:

What to include in labor burden
The calculator uses five cost categories — here is what each covers, aligned with the tool's input fields:
- Employer payroll taxes — FICA (Social Security + Medicare employer share: 7.65%), FUTA (up to 0.6%), and SUTA (state-specific). These are statutory costs tied to every dollar of wages.
- Benefits — employer contributions to health insurance, dental, vision, and retirement plans (401k match, SIMPLE IRA). These vary widely by plan generosity.
- Workers' comp / insurance — workers' compensation premiums, employer liability insurance, and similar payroll-linked insurance policies. Rate varies by industry classification code.
- PTO and other burden cost — the cost of paid vacation, sick leave, and holidays (wages paid for non-productive time). Also includes training, onboarding, uniforms, or other directly employee-linked costs.
The most important rule is consistency — use the same set of categories every time you calculate burden rate. Changing what you include between periods makes comparisons meaningless.
How to calculate burden rate — step by step
Worked examples
Four scenarios aligned with the calculator's three presets plus a fourth showing how to apply burden rate directly to an hourly wage.
Moderate burden — typical service business
Wages $8,000 · Tax $612 · Benefits $980 · Insurance $260 · PTO $348 · 320 hrs
→ Moderate burden. Base rate $25.00/hr → burdened $31.88/hr (+$6.88)
Low burden — minimal benefits package
Wages $8,000 · Tax $580 · Benefits $520 · Insurance $160 · PTO $140 · 320 hrs
✓ Low burden. Base $25.00/hr → burdened $29.38/hr (+$4.38)
High burden — comprehensive benefits
Wages $8,000 · Tax $640 · Benefits $1,500 · Insurance $340 · PTO $620 · 320 hrs
⚠ High burden. Base $25.00/hr → burdened $34.69/hr (+$9.69)
Apply known burden rate to hourly wage
If you already know the burden rate (e.g. 27.50%), apply it directly to an hourly wage:
→ Quick way to apply a known burden rate to any wage level.
Typical burden rate ranges
Burden rate varies significantly by industry, benefits generosity, location, and worker classification. These ranges are common reference points — not targets:
Burden rate vs labor cost vs overhead rate
These three terms are related but measure different things. Mixing them produces incorrect pricing and misleading cost reports.
The practical rule: use burden rate when you want the real cost of an hour of direct labor. Use overhead rate when you want to recover all indirect business costs across all revenue-generating activity.
Common mistakes to avoid
- Using inconsistent burden cost definitions. If payroll taxes are in this month's burden but not last month's, the rates are not comparable. Define categories once and apply them consistently across all periods.
- Dividing by total burdened cost instead of direct wages. Burden rate always uses direct wages as the denominator — not total labor cost including burden. Dividing by the wrong base produces a ratio that cannot be compared across periods.
- Mixing burden with full overhead. Not all indirect costs belong in burden rate. Facility costs, admin salaries, and software expenses are overhead — not employment burden — unless you are building a fully loaded labor rate for a specific purpose.
- Ignoring burden when pricing jobs. Quoting based on base wage rate alone systematically underprice labor-intensive work. The fully burdened hourly rate is the correct cost floor for any job, project, or service quote.
- Not updating burden assumptions annually. Payroll tax rates (especially SUTA), workers' compensation premiums, and benefit costs change each year. Stale burden rate assumptions quietly erode margins.
FAQ
What is the burden rate formula?
Burden Rate (%) = Total Burden Cost ÷ Direct Wages × 100. Total burden cost is the sum of all labor-related overhead items: payroll taxes, benefits, insurance, PTO, and other employment costs. Fully Burdened Labor Cost = Direct Wages + Total Burden Cost.
What costs are included in burden rate?
Common items: employer payroll taxes (FICA, FUTA, SUTA), workers' compensation insurance, health and dental benefits, retirement contributions, and paid time off. Some businesses also include training, uniforms, and other directly employee-linked costs. The exact list should be defined consistently.
What is a typical burden rate?
For most US employers, 20–30% is a common range. A lean benefits structure might run 15–20%. A comprehensive package with strong health, retirement, and generous PTO can push 35–40%. Union contracts and high-risk industry workers' comp can push above 40%.
Is burden rate the same as overhead rate?
No. Burden rate focuses specifically on labor-related employment costs on top of wages. Overhead rate is broader — it includes all indirect business costs such as rent, utilities, and admin expenses. Burden rate is one layer inside total overhead.
How do I use burden rate for job pricing?
Use the fully burdened hourly rate as your labor cost floor when quoting jobs. Formula: Wage × (1 + Burden Rate / 100). For example, at a 27.5% burden rate, a $25/hr wage becomes a $31.88/hr true cost. Any quote using $25/hr will underprice the labor component by $6.88 per hour worked.
Should I use direct wages or total labor cost as the denominator?
Always use direct wages as the denominator. Burden rate is defined as burden cost relative to the wage base — using total labor cost (which already includes burden) produces a lower, misleading ratio and breaks comparability with industry benchmarks.
