The short answer

To calculate a staffing bill rate, add employer burden — payroll taxes, workers' compensation and benefits — to the contractor's pay rate to get true hourly cost, then divide that cost by one minus your target gross margin. Markup is measured against pay; margin is measured against the bill rate.

Solve for

%
True hourly cost (pay + burden)$28.13
Burden per hour$3.13
Bill rate$36.06
Gross profit per hour$7.93
Gross margin22.0%
Markup on pay rate44.2%
Weekly gross profit$3,173.08
Annualised (48 weeks)$152,307.69

Markup and margin are not the same number. A 30% markup on a $25 pay rate is a bill rate of $32.50 and a gross margin of about 23% before burden — which is why agencies quoting on markup routinely earn less than they think.

Questions founders ask

How do you calculate a staffing agency bill rate?

Start with the contractor pay rate, add employer burden — FICA, FUTA and SUTA, workers' compensation and any benefits or PEO cost — to get your true hourly cost. Then divide that cost by one minus your target gross margin. Cost of $28.50 at a 25% target margin gives a bill rate of $38.

What is the difference between markup and gross margin?

Markup is expressed against the pay rate; margin is expressed against the bill rate. A 30% markup on a $25 pay rate is a $32.50 bill rate, which is a 23% gross margin before burden and lower after it. Quoting on markup while budgeting on margin is a common and expensive error.

What burden rate should a staffing agency use?

Burden is employer payroll taxes, workers' compensation premium, unemployment insurance, any benefits and any PEO or employer-of-record fee. It varies by state, vertical and claims history, and is commonly in the low double digits as a percentage of pay — but use your own carrier and payroll numbers, not a rule of thumb.

How much do staffing agencies charge employers?

For temporary and contract placement, agencies charge a bill rate that covers the worker's pay, employer burden and a gross margin. For permanent placement the standard model is a percentage of first-year salary. The right number for you depends on your burden and the value of the role, not on an industry average.
