What it means
Utilisation is productive hours divided by available hours. Chargeable utilisation counts only the hours a customer pays for.
Why it matters
In a people business it is the central economic metric: revenue is roughly rate times chargeable hours, so a few percentage points of utilisation is the difference between profit and loss.
What it looks like in practice
Realistic targets are well below 100%. Sustained high utilisation leaves no capacity for sales, training, holiday or the unexpected, and it produces burnout and errors.
What to watch out for
Chasing utilisation by counting things as chargeable that the customer will not pay for. The invoice, not the timesheet, is the test.
Where to get proper advice
Your own timesheet data and your invoiced hours side by side. The gap is where the money goes.
