How this instrument works
A bill rate is what a staffing or consulting firm charges a client for an hour of a contractor's time; the pay rate is what that contractor actually receives. The two are never the same figure, and the gap between them is the agency markup — not pure profit, but a layer that funds employer payroll taxes, workers' compensation, benefits administration, and the cash-flow gap between paying a worker weekly and collecting from a client on net-30 or net-60 terms.
The formula multiplies the pay rate by one plus the markup, the same shape a retail markup calculation uses on cost and price — but the inputs mean something different here. A shop's cost is a one-time wholesale invoice; a pay rate is a wage the agency is contractually obligated to fund every period, whether or not the client has settled the last one. A recruiter pricing a new contract, or a vendor-management-system program manager checking a submitted figure against a client ceiling, runs this exact multiplication before a placement is confirmed.
This sheet treats the markup as a single percentage, the way a rate card usually presents it to a client, rather than breaking it into statutory payroll burden, benefits, overhead and margin separately. That decomposition matters for pricing a book of business from scratch, but the number most staffing conversations start from — what a given pay rate becomes once the standard markup is applied — is exactly what this instrument returns.
- Enter Pay rate to the worker, $/hr — the wage already agreed with the contractor, before any markup.
- Set Agency markup, % to the percentage your firm adds on top of that pay rate.
- Read Bill rate to the client for the hourly figure to quote or invoice.
- Adjust either field to see how a markup change moves the bill rate before a quote goes out.
Worked example — $35/hr contractor, 50% markup
Take a contractor with Pay rate to the worker, $/hr set to 35 and Agency markup, % set to 50. The instrument computes 35 × (1 + 50 ⁄ 100) = 35 × 1.5, returning a Bill rate to the client of $52.50 an hour — the figure that lands on both the client's invoice and the agency's pricing sheet for that placement.
That $17.50 spread is not pure profit; it funds employer payroll taxes, workers' compensation premiums, any benefits the agency extends to the contractor, and the margin that makes running payroll on someone else's behalf worthwhile. Drop the markup to zero and the bill rate collapses to the same $35 — pass-through billing with no agency margin at all — while raising it to 100% would put the client at $70 for the identical hour of work.
Questions
What does the agency markup actually pay for?
It funds everything beyond the wage itself: employer-side payroll taxes, workers' compensation and unemployment insurance, any benefits the agency extends to the contractor, and the cash-flow gap between paying the worker weekly and collecting from the client on net-30 or net-60 terms. Whatever remains after those costs is the agency's actual margin on the placement — usually smaller than the headline markup suggests.
How is a bill rate different from a pay rate?
Pay rate is what lands in the contractor's paycheck; bill rate is what the client is invoiced for that same hour. The difference funds the agency's costs and profit, and confusing the two is a common error in early negotiations — a contractor quoted '$50 an hour' needs to know whether that figure is their pay or the client's bill before accepting an offer.
Is a 50% markup typical for staffing placements?
Markups vary widely by industry, contract length, and whether benefits are included — light-industrial staffing often runs lower, specialized IT or clinical placements often run higher, and a markup covering full benefits sits above one covering only statutory payroll costs. Fifty percent is a common enough reference point to model with, not a rate this instrument recommends.
How is this different from a retail markup calculation?
The arithmetic is identical — multiply a base figure by one plus a percentage — but the base means something different. A retailer's cost is a one-time wholesale invoice; a staffing agency's pay rate is a recurring wage obligation the firm must fund every pay period regardless of when the client actually pays. That funding gap is why staffing firms track bill rate as its own figure rather than reusing a generic markup tool.
What happens if the markup is set to zero?
The bill rate equals the pay rate exactly — the client is charged precisely what the contractor is paid, with nothing left over for the agency's payroll taxes, insurance, or the administrative cost of running that payroll. This is sometimes called pass-through billing, and it only makes financial sense for an agency if it is being compensated some other way, such as a flat placement fee.
Does the bill rate here include overtime or per-diem charges?
No — this figure is the straight-time hourly bill rate implied by the base pay rate and markup alone. Overtime premiums, shift differentials, per-diem, travel reimbursement, and any client-specific surcharges are calculated separately and layered on top of, or in place of, this base figure depending on the contract terms.
