What to enter
| Input | Meaning and units |
|---|---|
| Billable hours (hours) | Enter billable hours in hours. Use the measurement basis described below. |
| Available hours under chosen policy (hours) | Enter available hours under chosen policy in hours. Use the measurement basis described below. |
Understanding your result
Use utilization with realization, delivery quality and workload context. A high utilization percentage alone is not a profitability or employee-performance conclusion.
Common mistakes
- Scheduled hours and productive available hours are different bases.
- Do not sum overlapping time entries.
- Mixing annual and monthly periods, or leaving out a cost that the model does not include.
Check your calculation
- Compare a simple one-period or zero-change case with hand arithmetic before applying a longer scenario.
Choose a consistent measurement basis
Specify whether availability excludes leave, holidays, training and internal work. Use recorded hours and one period; compare teams only under the same denominator policy.
A second independently worked case
No billable time among 160 available hours gives 0% utilization. Inputs: Billable hours: 0 hours; Available hours under chosen policy: 160 hours. Results: Billable utilization: 0 %; Non-billable available hours: 160 hours.
Precision and output units
Displayed results: Billable utilization in %, rounded to 2 decimal places; Non-billable available hours in hours, rounded to 3 decimal places. Display rounding does not establish the precision of the original measurements or estimates. A small positive rate can round to 0.00%; inspect the underlying counts before treating displayed zero as an absence of events.

- Compare Billable Utilization across scenarios under matching definitions.
How it works
Divide billable hours by the positive available-hours denominator and multiply by 100. Subtract billable time to show the non-billable part under this chosen convention.
Worked example
120 ÷ 160 × 100 = 75%; forty available hours are not classified billable. Enter billable hours 120 hours, available hours under chosen policy 160 hours. The independently worked result is billable utilization 75 %; non-billable available hours 40 hours. Compare this example with your reporting definitions before substituting your own figures.
FAQ
Should available hours include holidays and leave?
Use the availability policy appropriate to your reporting purpose and document it. Comparing percentages under different leave and capacity policies can be misleading.
Does high utilization prove profitability or employee performance?
No. Price realization, delivery costs, quality, workload and time-recording rules are separate factors. This ratio summarizes the entered time classifications.
