Professional staffing average bill rate is the average hourly amount a staffing provider bills customers for contract talent services.
Robert Half's contract talent bill rates increased 1.2% year over year in the second quarter of 2026 even as hours worked fell 2.8%. Kforce's 2025 average Technology bill rate was about $90 per hour, while Finance and Accounting averaged about $53 per hour.
A higher rate can be mix, not pure price
Bill rates change with skill level, geography, client mix, assignment type, and contract structure. A provider shifting toward senior technology assignments can report a higher average rate even if like-for-like pricing barely moves.
That is why bill rate belongs beside billable hours and the revenue volume-rate bridge, not in isolation.
Revenue growth still depends on volume
A 5% increase in bill rate does not offset a 10% decline in hours. The arithmetic is multiplicative: roughly, contract staffing revenue is driven by billable hours times the effective bill rate, with smaller adjustments for expenses and other items.
For profitability, compare the customer bill rate with the worker pay rate through the pay-bill spread.
