Labor burden
Labor burden is what an employee costs you beyond wages: employer payroll taxes, workers’ compensation, and benefits, usually stated as a percentage of wages.
- LAW
- 26 U.S.C. §3111 (FICA) and §3301 (FUTA)
- BOUNDARY
- Each wage base generally resets every calendar year
- FORMULA
- Employer costs divided by wages, same period
- WATCH FOR
- A flat rate misstates early-year payroll tax
Labor burden turns a wage into what an hour of work actually costs you. Divide the burden by wages for the same period and you get the labor burden rate, which job costingJob costing (labor allocation). Job costing, also called labor allocation, is coding hours and pay to the job, project, client, location, department, or cost code where the work happened.Click to open the term, bids, and bill rates build on. Which costs count is a business choice, not a legal definition: some employers add training or equipment, and overhead such as rent usually sits outside it. Whatever you include, define it once and apply it the same way every period, so job reports stay comparable.
What goes into labor burden?
Labor burden has two parts. Statutory costs follow every wage you pay: your share of Social Security and Medicare, federal and state unemployment tax, and workers’ compensationWorkers’ compensation. Workers’ compensation is state-mandated insurance that pays medical expenses and partial lost wages when an employee is injured or becomes ill because of their job.Click to open the term where you carry it. The rest are costs you choose, such as health coverage and retirement contributions. Paid leave depends on the base: divide by wages for hours worked and leave pay is burden; divide by all wages paid and it is already in the base.
| COST | EMPLOYER RATE | STOPS AT |
|---|---|---|
| Social Security | 6.2% | $184,500 of wages (2026) |
| Medicare | 1.45% | No wage base limit |
| Federal unemployment tax (FUTA) | 6.0%, generally 0.6% after the state credit | First $7,000 a year of each employee’s wages |
| State unemployment insurance (SUI) | Your assigned state rate | The state’s own wage base |
| Workers’ compensation | Typically a rate per $100 of payroll, by class code | Set by your state and insurer |
| Benefits | Your share of plan costs | Your plan terms |
How do you calculate a labor burden rate?
The labor burden rate is employer costs divided by wages for the same period. Benefit costs averaged 30.0% of private industry employer compensation costs in June 2026, according to the Bureau of Labor Statistics, which counts paid leave and supplemental pay such as overtime premiums and bonuses as benefits. That is a share of total compensation, not of wages: the same $14.07 an hour on $32.82 of wages is a 42.9% rate on wages.
- 01
Pick the base. Wages for hours worked, or all wages paid including leave, and keep the same one every period.
- 02
Total what you pay on top of wages for that period: payroll taxes, workers’ compensation premiums, and your share of benefits.
- 03
Divide by the base. $18,000 a year of employer costs on $60,000 a year of wages is a 30% labor burden rate.
- 04
Convert to an hourly amount by multiplying the wage by the rate: 30% on $25.00 an hour adds $7.50, a loaded rate of $32.50.
Why does a loaded rate drift from actual cost?
A flat labor burden rate spreads payroll taxesPayroll tax.

Actual burden is therefore highest early in the year and falls as employees reach each base, while Medicare never stops.
