TL;DR

Gross margin in staffing is the percentage of bill rate revenue that remains after deducting direct labour costs — the worker's pay rate and the employer's payroll taxes and insurance. It is the primary profitability metric for temporary and contract placements. According to Staffing Industry Analysts, average gross margin across US temporary staffing firms sits around 25%, ranging from approximately 14% at low-margin commercial/industrial firms to 41%+ at high-skill professional or search-focused firms.

Key Takeaways

• Gross margin formula: (bill rate − pay rate − burden) ÷ bill rate × 100; at a $30 bill rate with $20 pay rate and $5 burden, gross margin = 16.7%
• SIA benchmarks show IT/professional temp staffing gross margins averaging 23–26%, while commercial/industrial staffing firms typically run 18–22% due to thinner markups and heavier workers' comp costs
• Direct hire placements carry 100% gross margin on the fee because there are no ongoing payroll costs — which is why adding perm search to a temp desk dramatically lifts the firm's blended gross margin percentage
• Gross margin differs from net margin: gross margin only deducts direct labour costs; net margin also deducts recruiter salaries, rent, technology, and all other operating expenses, which at many staffing firms runs 18–22% of revenue

FAQ

Q: What is a good gross margin for a staffing company? A: It depends on the staffing segment. Industrial and light commercial temporary staffing firms typically run 18–22% gross margin; IT and professional temp staffing firms average 23–26%; executive search firms with contingency or retained models operate at 50%+ gross margin on fees. SIA's research shows the aggregate US temp staffing average is approximately 25%. Firms below 18% are typically competing on price alone and have limited buffer for cost increases.

Q: How is gross margin calculated in staffing? A: Gross margin % = (bill rate − pay rate − burden costs) ÷ bill rate. Burden includes employer FICA (7.65% of pay rate), FUTA (~0.6%), SUTA (varies by state and employer experience, typically 1–4%), workers' compensation insurance, and any benefits pass-through. For a contractor billed at $40/hr with a $28 pay rate and $5.50 burden, gross margin = ($40 − $28 − $5.50) ÷ $40 = 16.25%.

Q: How does gross margin differ from markup? A: Markup is the percentage added to the pay rate to reach the bill rate — calculated on the cost base. Gross margin is the percentage of the bill rate kept after paying all direct labour costs — calculated on the revenue figure. A 40% markup on a $25 pay rate gives a $35 bill rate; if burden is $6, gross margin is ($35 − $25 − $6) ÷ $35 = 11.4%. Higher markup does not proportionally translate to higher gross margin because burden costs grow with pay rate.

Why Gross Margin Is the Staffing Industry's Core Profitability Signal

Revenue volume is a vanity metric in staffing. A firm billing $50 million at 18% gross margin generates the same gross profit as one billing $30 million at 30%. The two businesses look dramatically different on the top line and almost identical at the point where operating decisions actually get made. Staffing Industry Analysts benchmarks gross margin as the primary measure agency principals use to evaluate their business health and set pricing strategy, which is why every serious conversation about desk performance starts here, not with headcount or fill rate.

The range across sectors is wide, and understanding where your firm sits determines everything from recruiter compensation design to which client segments to pursue. Industrial and light commercial temporary staffing firms typically run 18 to 22% gross margin; IT and professional services firms average 23 to 26%; niche technical or executive search operations often operate above 35%. A firm below 18% is generally competing on price alone and has limited buffer to absorb cost increases. One SUTA rate increase, one workers' comp claim, one client that renegotiates its rate card, and the margin disappears.

For staffing agency owners, gross margin is also the metric that reveals whether growth is profitable or just busy. Adding headcount to a desk running at 17% gross margin compounds the problem. The right response to a low-margin desk is usually repricing before scaling, not the reverse.

How to Calculate Gross Margin on a Placement

The formula is: (bill rate minus pay rate minus burden) divided by bill rate, expressed as a percentage. Burden is the sum of all employer-side payroll costs: FICA at 7.65% of pay rate, FUTA at approximately 0.6%, SUTA at typically 1 to 4% depending on state and the employer's experience rating, workers' compensation insurance (which varies significantly by occupation code), and any benefits contributions or admin fees passed through on the worker's pay.

A worked example: a light industrial worker billed at $38 per hour with a $26 pay rate carries the following burden: FICA of $1.99, FUTA of $0.16, SUTA of $0.78 at a 3% rate, workers' compensation of $1.30 at a mid-range rate. Total burden: $4.23. Gross profit per hour: $38 minus $26 minus $4.23, which is $7.77. Gross margin: $7.77 divided by $38, which is 20.4%. If that same state increases SUTA by one percentage point, burden rises to $4.49, gross profit falls to $7.51, and gross margin drops to 19.8%. A single policy change in one state shifts the unit economics on every hour billed to every client in that state.

The practical implication for agency principals is that burden costs must be recalculated when state tax rates change, workers' comp codes are reclassified, or a client's occupation mix shifts. Gross margin models that treat burden as a fixed percentage are always lagging reality. The firms with the clearest visibility into per-placement gross margin are the ones recalculating burden assumptions at least quarterly.

Gross Margin vs Net Margin

Gross margin only covers the placement cost: the difference between what the client pays and what it costs to put the worker in that seat. It does not cover the cost of running the business. Recruiter salaries, team leader commissions, office costs, ATS and VMS technology fees, compliance and legal costs, marketing, and back-office overhead typically consume 18 to 22% of revenue at well-run staffing firms. That means a firm operating at 25% gross margin is generating 3 to 7% net margin before tax. A firm at 20% gross margin, after the same operating cost structure, is breaking even or operating at a loss.

The distinction matters when evaluating desk performance or acquisition targets. A desk with $5 million in revenue at 26% gross margin looks better than one at $8 million with 18%, but a proper comparison requires understanding the incremental operating cost each desk carries. A large warehouse desk with 200 contractors and a team of three recruiters has different unit economics than a technical desk with 40 placements per year managed by one senior biller. Gross margin is the right starting point. Net margin is the right finishing point.

Gross Margin in Practice

A finance director at a regional staffing firm reviews a quarterly P&L showing two active desks. The IT desk carries 35 contractors billing at an average $75 per hour with a 26% gross margin. The warehouse desk carries 120 workers billing at an average $22 per hour with a 19% gross margin. The warehouse desk generates more revenue in absolute terms, but the IT desk contributes more gross profit per billed hour and, critically, per recruiter headcount. The IT desk has two recruiters; the warehouse desk has four.

The analysis drives a resource allocation decision: rather than adding to the warehouse team to grow volume, the firm invests in a third IT recruiter. The objective is not to shrink the warehouse business but to grow the higher-margin desk faster. Over four quarters, the blended gross margin of the firm improves from 21% to 23%, and total gross profit grows at a faster rate than headcount does. The margin improvement comes not from repricing existing business but from mix shift: more revenue running through the higher-margin channel.
