πΌ Bill Rate Calculator
From pay rate to profitable bill rate.
Client bill rate at the markup
Estimates for planning only, not financial advice.
The bill rate is what the client pays per hour for a contract worker: the pay rate marked up to cover burden and margin. At a $45 pay rate with a 1.55 multiplier, the bill rate is $69.75 an hour, and the $24.75 spread, 35.5 percent of the bill, funds payroll taxes, insurance, overhead, and profit. Price it from the margin target backward and the business stays disciplined; price it from vibes and the spread quietly evaporates.
How to Use This Calculator
Enter the worker's pay rate, your markup multiplier, the burden rate (employment costs as a share of pay), and weekly hours. The calculator shows the bill rate, the spread, the gross margin after burden, and weekly and annual revenue per head.
Enter the pay rate you will pay the worker and the markup multiplier for the segment (1.4 light industrial, 1.55 professional, 2.0 niche).
Enter the burden rate: FICA, unemployment, workers' comp, and benefits as a percent of pay. State-specific costs belong here.
Read the gross margin after burden. Under 20 percent is thin for the risk; over 35 percent may not survive client negotiation. For independent pricing, see our freelance rate calculator.
The Formulas
Two ways to the same number: multiply forward from pay, or divide backward from margin. The backward form is the disciplined one: $45 pay with 20 percent burden is $54 loaded, and a 25 percent margin target gives $54 / 0.75 = $72.00. When a client pushes the rate down, the backward math shows exactly how much margin each dollar of concession costs.
Worked Example: $45 Pay at 1.55x
Pay rate: $45.00. Markup: 1.55. Bill rate: $69.75. Burden at 20 percent: $9.00, so loaded cost is $54.00. Spread: $24.75, which is 35.5 percent of the bill rate. Gross margin after burden: ($69.75 - $54.00) / $69.75 = 22.6 percent. At 40 hours a week, weekly revenue per head is $2,790, weekly loaded cost is $2,160, and weekly gross profit is $630, or $32,760 a year per billable head.
Negotiation test: the client counters at $65. New margin: ($65 - $54) / $65 = 16.9 percent, less than half the original. That $4.75 concession costs $9,880 a year per head (4.75 x 40 x 52). Concessions feel small hourly and are enormous annually, which is why the calculator shows annual figures: nobody negotiates well in per-hour terms.
Markup Benchmarks
| Segment | Typical multiplier | Gross margin target |
|---|---|---|
| Light industrial | 1.35 - 1.50 | 18-25% |
| Office / admin | 1.45 - 1.60 | 22-28% |
| Professional / IT | 1.55 - 1.80 | 25-35% |
| Niche / executive | 1.80 - 2.20 | 30-40% |
Higher skill means higher multiples because recruiting cost and falloff risk rise with specialization. But the market caps every segment: quote above the going multiple and the req goes to the competitor; quote below and you train clients to expect it.
Protecting the Spread
The spread leaks in predictable places: overtime billed at the wrong multiplier, unapproved hours, workers' comp surprises in high-risk states, and pay raises given without bill-rate increases. Contract discipline stops most of it: OT at 1.5x bill rate, hour caps with approval workflows, annual bill-rate escalators tied to pay raises, and conversion fees quoted upfront.
Review margins per client quarterly, not per invoice never: a client at 16.9 percent margin after concessions needs a rate increase, a pay adjustment, or a polite goodbye. The staffing business is a spread business, and spreads are managed in basis points and defended in contracts. Our billable hours calculator plans the hours side of the same economics, and the commission calculator structures recruiter incentives on the margin, not just revenue.
Negotiating Bill Rates
Anchor high and justify with burden, not greed. Clients accept rates when they see the math: the pay rate plus taxes, insurance, benefits, and overhead is already 1.4 to 1.6 times pay before profit. Showing a burdened cost build turns the negotiation from "your rate is too high" into "which costs can we discuss," a much better conversation. Never reveal the pay rate itself; negotiate the bill rate as the product.
Volume and duration are your discount levers: a 10 percent cut for a 12-month full-time engagement beats a 10 percent cut for a 4-week project, because utilization certainty has real value. Build rate escalators into multi-year deals to cover wage inflation, and revisit annually: a contractor whose market pay rose 8 percent while the bill rate sat flat is a resignation waiting to happen. The best rate is the one both sides can sustain for the whole engagement.

Frequently Asked Questions
What is a bill rate?
The hourly price a staffing firm charges its client for a worker's time. A contractor paid $45 an hour billed at a 1.55 multiplier costs the client $69.75 an hour. The spread covers payroll taxes, benefits, overhead, and the firm's profit.
How do you calculate bill rate from pay rate?
Bill rate = pay rate x markup multiplier, where the multiplier covers burden and margin. Common multipliers run 1.4 to 2.0: light-industrial near 1.4, professional roles 1.6 to 1.8, niche specialists 2.0 plus. At 1.55 on $45 pay, the bill rate is $69.75.
What is burden rate in staffing?
The employment costs on top of wages: employer payroll taxes (~7.65% FICA plus unemployment insurance), workers' compensation, and any benefits offered. Burden typically adds 15 to 30 percent to the pay rate before the firm adds its margin. Bill rate = (pay + burden) / (1 - target margin) is the precise form.
What is a good markup in staffing?
It depends on the segment: 25 to 40 percent markup (1.25x to 1.40x) is common in high-volume light industrial, 50 to 70 percent (1.5x to 1.7x) in professional staffing, and 80 percent plus for scarce specialists. Markup must cover burden first; what is left is gross margin, typically targeted at 20 to 30 percent of the bill rate.
Bill rate vs pay rate: what is the spread?
The spread (bill minus pay) funds everything the firm provides: payroll processing, insurance, compliance, recruiting, account management, and profit. On $45 pay at $69.75 bill, the $24.75 spread is 35.5 percent of the bill rate. Clients paying the spread buy flexibility and zero employment liability.
How do you hit a target margin?
Bill rate = loaded cost / (1 - target margin). For $45 pay with 20% burden ($54 loaded) and a 25% margin target: $54 / 0.75 = $72.00 bill rate. Working backward from margin instead of forward from markup keeps pricing disciplined when burden varies by state or role.
Should bill rates vary by state?
Yes, because burden does: workers' comp rates, unemployment insurance, and paid-leave mandates differ by state, and some cities add their own requirements. A national bill rate either overcharges low-burden states or bleeds margin in high-burden ones. Price by work location, not headquarters.
What is a conversion fee?
The fee when a client hires the temp worker permanently, typically a percentage of annual salary (15 to 25 percent) with a sliding scale that shrinks the longer the worker has been on assignment. It protects the firm's recruiting investment. Quote it upfront; surprising clients with it kills relationships.
How do overtime and holidays affect bill rates?
Overtime usually bills at 1.5x the bill rate (not 1.5x the pay rate), which expands margin on OT hours, and holiday pay terms should be in the contract. Define all of it before the assignment starts: OT multipliers, holiday billing, and who approves extra hours.
Bill rate vs freelance rate?
A freelancer's rate must cover everything (taxes, benefits, downtime, business costs) from one number, typically 1.5 to 3 times an equivalent salary hourly. A staffing bill rate splits the economics: the worker gets the pay rate, the firm keeps the spread for its costs and profit.
