How do staffing agencies make money?
Updated October 5, 2026 · 6 min read
Staffing agencies make money two ways. On contract placements they charge the client an hourly bill rate, pay the worker a lower pay rate, and keep the spread. On permanent placements they charge a one-off fee, usually 15% to 25% of first-year salary. The contract spread looks larger than it is, because employer taxes, insurance and benefits come out of it before anything reaches profit.
The contract spread
A client pays $85 an hour. The contractor is paid $60. The $25 difference is gross margin — not profit, and the distinction is where most misunderstanding of this industry lives.
Out of that $25 comes the employer half of Social Security and Medicare at 7.65%, federal and state unemployment insurance, workers' compensation at a rate that varies sharply by job classification, and any benefits offered. On a $60 pay rate those statutory costs alone commonly run $8 to $12 an hour.
What remains covers the recruiter's salary, the sales cost of winning the account, the back office that processes timesheets and chases invoices, and the gap between paying the contractor weekly and being paid by the client in 45 or 60 days. Net margins across the staffing industry typically land in low single digits.
Markup and margin are different numbers
Markup is expressed against the pay rate: $60 to $85 is a markup of about 42%. Margin is expressed against the bill rate: the same deal is a margin of about 29%.
Clients and agencies routinely quote different numbers for the same arrangement because they are using different denominators. It is worth confirming which one is meant before agreeing anything.
Permanent placement fees
On a direct hire the agency charges a percentage of first-year salary, commonly 15% to 25%, sometimes more for executive or hard-to-fill roles. The fee is normally invoiced when the candidate starts.
Most agreements include a guarantee period — typically 30 to 90 days — during which the agency replaces the candidate at no charge, or refunds on a sliding scale, if they leave or are terminated.
Permanent fees are higher-margin but lumpy. Contract placements are lower-margin but recur every week the person works, which is why agencies with a contract book have steadier businesses than those living on placements.
What actually determines profitability
Three things, none of which are the margin percentage.
Utilisation: a recruiter's cost is fixed whether or not anyone is placed. Time to fill: a requirement filled in five days earns from week one, while the same requirement filled in thirty may be filled by someone else first. And cost to serve: how much human time each placement consumes between the requirement arriving and the invoice being paid.
That last one is where agencies on thin VMS margins live or die. If a placement needs hours of manual work — re-keying timesheets, assembling invoices, correcting rebills — a 29% margin can be unprofitable. The same margin is comfortable when that work is automated.
Common questions
What is a typical staffing agency margin?
Gross margins on contract work commonly run 25% to 40% of the bill rate, varying by skill level, volume and whether the business comes through a VMS. Net margin after employer taxes, insurance, benefits and overhead is far lower — low single digits is normal across the industry.
Do candidates pay staffing agencies?
No. In the United States the client pays, either as an hourly margin or a placement fee. An agency asking a job seeker for money is not operating normally.
Why is the bill rate so much higher than my pay rate?
Because the agency pays the employer portion of payroll taxes, unemployment and workers' compensation insurance, often benefits, and carries the cost of paying you weeks before the client pays them. The visible spread is not profit.
What is a conversion fee?
A fee paid when a client hires a contract worker permanently, compensating the agency for the hourly margin it stops earning. It usually declines the longer the contract has run.
