A professional staffing revenue volume-rate bridge separates the change in contract staffing revenue into the amount of work delivered, the rate charged for that work, and smaller items such as billable expenses.
Kforce makes the bridge explicit. In Technology for the second quarter of 2026, higher hours billed added about $10.521M of revenue versus the prior year, bill-rate changes added $1.851M, and billable expenses reduced revenue by about $0.181M.
Volume and rate can point in opposite directions
Robert Half's second-quarter contract talent revenue fell 1.6%. Hours worked declined 2.8%, while average bill rates increased 1.2%.
That combination tells a more useful story than the headline revenue number: underlying staffing volume weakened, while pricing and mix partially offset the decline.
Start with hours, then ask what moved rate
The volume leg is billable hours. The rate leg is the average bill rate, which can itself move because of skill, geography, assignment, and client mix.
For quarter-to-quarter work, add the billing-day adjustment before concluding that volume accelerated or slowed. The bridge is an operating decomposition, not a standardized GAAP reconciliation.

Decompose staffing revenue growth
Compare contract revenue through hours, bill-rate, billable-expense, and calendar drivers rather than relying on the headline growth rate.
