Utilisation rate answers one question only: of the hours your team is available to work, how many were spent on billable client work? It says nothing about whether those hours were billed at full value — that's realization, a different metric entirely, and conflating the two is one of the most common agency-finance mistakes.
The formula
Utilisation Rate = (Billable Hours ÷ Available Hours) × 100
Real benchmarks
Production staff (designers, developers, writers doing the actual delivery work) should run 75-85% utilisation. Blended across the whole team, including account management and leadership who carry non-billable responsibility by design, healthy agencies run 55-65%. A number outside those bands in either direction is worth investigating — too low signals overstaffing or poor project flow; unusually high can signal burnout risk or under-resourced delivery.
Why utilisation alone can mislead you
A team can hit 85% utilisation while still losing money, if the hours logged were billed at a steep discount off standard rates. That gap is realization rate — (Revenue Billed ÷ Standard-Rate Value) × 100, healthy at 85-95%, a real problem below 80%. Utilisation tells you the team was busy. Realization tells you whether being busy actually paid.
