Staffing Markup vs Margin: Why 34% Nets Closer to 3%

Staffing is the business most often confused by its own pricing, because markup feels like margin and it is not. A recruiter quotes a bill rate, subtracts the pay rate, and the spread looks healthy. Then the year closes and net margin is 3 to 6%, which is the industry norm, and nobody can explain where the spread went. It went into four costs that the markup math never counted.

Here is the teardown, and how to rebuild it from your own rates.

Markup is not margin

Start with the number every agency quotes: the markup, the spread as a percent of the bill rate.

A worker paid $17.00/hr, billed at $25.76/hr, is an $8.76 spread. As a percent of the bill rate that is about 34%. It feels like a 34% margin. It is not, because the pay rate is not the full cost of the worker, and the spread has to cover the cost of running the agency and financing the payroll. Watch what the spread actually has to absorb.

Leak 1: full employment burden (the biggest one)

The pay rate is what the worker sees. The agency pays much more:

• Employer FICA: 7.65% (IRS Topic 751).
• Federal and state unemployment insurance, plus workers comp, which varies by role and state.
• Benefits: the BLS Employer Costs for Employee Compensation series puts benefits near 30% of total compensation (BLS ECEC).
• For W2 staffing over the ACA threshold, the employer-mandate penalties are real money: the 2026 figures run in the low-to-mid thousands per affected employee per year.

Load all of that and the true cost of that $17.00/hr worker is well above $17. The spread is smaller than it looked before you covered a single overhead dollar.

Leak 2: recruiter and sourcing time

The recruiter's salary is booked as company overhead, not charged to the requisition it filled. But that time is a direct cost of the placement. The BLS median for human resources specialists (SOC 13-1071) is about $67,650/yr (BLS OEWS); fully loaded and divided across the placements a recruiter fills in a year, it takes a few points off every deal.

Leak 3: financing weekly payroll on net-30 to net-60 terms

The agency pays the worker every week. The client pays the invoice in 30 to 60 days. That gap is financed, either by factoring (commonly 1 to 4% of invoice value per 30 days) or by the agency's own cost of capital. Either way it comes off the spread, and it scales with how slowly the client pays.

Leak 4: bench pay, backouts, and replacements

Idle-bench pay between assignments, and the cost of re-placing a candidate who washes out, get absorbed as overhead rather than charged to the original deal. This one is structural and hard to source cleanly, so treat it as directional, but it is real and it is why net margin lands where it does.

Add the four leaks to a 34% markup and the net margin that reaches the bottom line is typically 3 to 6%, consistent with published staffing-agency net margins.

How to rebuild your real margin

1. Start from the spread, bill rate minus pay rate, as a percent of the bill rate.
2. Re-cost the worker fully burdened: pay rate plus the all-in employment burden. BLS ECEC puts total benefits near 30% of compensation, and that already covers the legally-required load (employer FICA 7.65%, unemployment, workers comp) plus health and retirement, so apply the ~30% once rather than adding FICA/UI/WC separately. Recompute the true spread over fully-burdened cost, not pay rate.
3. Charge recruiter time: take the fully-loaded recruiter cost, divide by placements filled per year, and subtract that per placement.
4. Subtract the AR carry: if you factor, use the factoring fee; if you self-fund, use (days to collect divided by 365) times your cost of capital times the invoice.

The number left is your real margin. If it is a fraction of your markup, that is not a mistake, it is the structural economics of staffing, and it is exactly why bill-rate discipline and fast collection matter more here than in almost any other service business.

Why this is directional

The 34%-markup-to-3%-margin path is an illustration of the mechanism, not a measured survey of your book. The input rates (FICA, benefits share, recruiter wage, factoring range) are sourced to named public data; the exact points depend on your state, role mix, and how fast clients pay. The point stands regardless: markup is a pricing input, margin is the outcome, and confusing the two is how staffing agencies grow revenue while making almost nothing.
