Billable utilisation: Measure billable hours as a percentage of available working hours.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Billable utilisation to answer this question: measure billable hours as a percentage of available working hours? Enter Billable hours and Available working hours; the calculator shows Billable utilisation. Try changing one number and watch what happens to Billable utilisation. The answer tells you Billable utilisation.
Age 15Explain it to a 15-year-oldConnect it to the formula
Define available hours consistently and decide whether leave, training and internal work belong in the denominator before comparing teams or periods. The rule is Billable utilisation = billable hours ÷ available hours × 100. Its input values are Billable hours, Available working hours, and the main result is Billable utilisation. Try changing one number and watch what happens to Billable utilisation.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Billable utilisation = billable hours ÷ available hours × 100, evaluated from Billable hours, Available working hours to produce Billable utilisation. Define available hours consistently and decide whether leave, training and internal work belong in the denominator before comparing teams or periods. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Measure billable hours as a percentage of available working hours.
Why the business model works
Define available hours consistently and decide whether leave, training and internal work belong in the denominator before comparing teams or periods.
Inputs and operating assumptions
This model uses Billable hours (at least 0), Available working hours (at least 0.01). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Billable utilisation = billable hours ÷ available hours × 100
What the calculator produces
The primary output is Billable utilisation; it also exposes Non-billable hours. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
