Four Terms, One Placement
Every hour a placed worker bills touches all four numbers at once. Murray Resources' recruiting-industry glossary lists bill rate, pay rate, markup, and gross margin as core placement-economics terms, and for good reason: get any one of them wrong in a quote and the other three are wrong too, because they are all derived from the same two inputs.
Pay Rate: What the Worker Earns
Pay rate is the simplest of the four: it is the hourly wage the placed candidate actually receives. It is also the number every client-facing markup or margin calculation starts from, since the other three terms all exist to describe the relationship between this number and what the client pays.
Bill Rate: What the Client Pays
Bill rate is the hourly rate the client is invoiced. It includes the pay rate plus everything the agency absorbs on the worker's behalf, payroll taxes, workers' comp, unemployment insurance, benefits where applicable, and the agency's margin. It is the one number of the four the client actually experiences directly, which is exactly why the previous guide in this series argues you should lead a pricing conversation with this figure, not with a percentage.
Markup: The Spread, Measured Against Pay Rate
Markup is the dollar difference between bill rate and pay rate, expressed as a percentage of the pay rate. If a worker's pay rate is $20 an hour and the bill rate is $28, the spread is $8, and the markup is $8 divided by $20, or 40%. Markup is the number staffing agencies talk about internally most often, because it is the multiplier applied directly to pay rate when building a quote.
Gross Margin: The Same Spread, Measured Against Bill Rate
Gross margin is the identical $8 spread from the example above, but expressed as a percentage of the bill rate instead of the pay rate: $8 divided by $28, or roughly 28.6%. Same dollars, different denominator, meaningfully different percentage. A 40% markup and a 28.6% margin describe the exact same placement. Confusing the two, quoting a "40% margin" when you actually mean a 40% markup, either overstates your profitability internally or misquotes a client externally, and it is one of the more common mistakes a new BD rep makes in their first few months.
Why This Distinction Matters for Every Other Deal-Structure Decision
Getting markup versus margin straight is not academic. It determines whether you are comparing apples to apples when benchmarking your own pricing, whether a spreadsheet built for one metric is quietly misleading you when read as the other, and whether the number you quote internally to a manager matches what actually shows up on the client invoice. It also underlies the fee-structure and contract decisions covered in the companion guides on contingency versus retained search and perm-fee structuring, both of which assume you are working from a clean, consistent definition of spread.
| Term | What It Measures | Formula | Example (pay rate $20, bill rate $28) |
|---|---|---|---|
| Pay rate | What the worker earns per hour | n/a | $20.00 |
| Bill rate | What the client pays per hour | Pay rate + spread | $28.00 |
| Markup (spread) | The gap, measured against pay rate | (Bill rate − pay rate) ÷ pay rate | $8 ÷ $20 = 40% |
| Gross margin | The same gap, measured against bill rate | (Bill rate − pay rate) ÷ bill rate | $8 ÷ $28 = 28.6% |
The dollar figures here are a worked illustration of the formulas, not a market benchmark or a typical rate. Your own pay rate and target spread will vary by role, segment, and market.
What this means for you
- Markup is the spread measured against pay rate. Gross margin is the identical spread measured against bill rate. They are never the same percentage for the same placement.
- Bill rate is the only one of the four terms the client actually experiences directly, which is why it belongs at the front of any client-facing conversation.
- Confusing markup with margin is one of the most common early mistakes in staffing BD, and it quietly distorts both internal reporting and client quotes if it goes uncaught.
