Understand Utilization Revenue Leakage
One idea, three depths
Choose how deeply to explain Utilization Revenue Leakage
Utilization Revenue Leakage: Estimate revenue lost when billable utilisation falls below a target level.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Utilization Revenue Leakage to answer this question: estimate revenue lost when billable utilisation falls below a target level? Enter Available staff hours, Target billable utilisation, Actual billable utilisation, and 1 other input; the calculator shows Estimated revenue leakage. Try changing one number and watch what happens to Estimated revenue leakage. The answer tells you Estimated revenue leakage.
Age 15Explain it to a 15-year-oldConnect it to the formula
The estimate assumes unutilised target hours could have been sold at the entered rate and ignores collection risk. The rule is Revenue leakage = available hours × (target utilisation − actual utilisation) × billing rate. Its input values are Available staff hours, Target billable utilisation (%), Actual billable utilisation (%), Average billing rate, and the main result is Estimated revenue leakage. Try changing one number and watch what happens to Estimated revenue leakage.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Revenue leakage = available hours × (target utilisation − actual utilisation) × billing rate, evaluated from Available staff hours, Target billable utilisation (%), Actual billable utilisation (%), Average billing rate to produce Estimated revenue leakage. The estimate assumes unutilised target hours could have been sold at the entered rate and ignores collection risk. 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
Estimate revenue lost when billable utilisation falls below a target level.
Why the business model works
The estimate assumes unutilised target hours could have been sold at the entered rate and ignores collection risk.
Inputs and operating assumptions
This model uses Available staff hours, Target billable utilisation, Actual billable utilisation, Average billing rate. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Revenue leakage = available hours × (target utilisation − actual utilisation) × billing rate
What the calculator produces
The primary output is Estimated revenue leakage; it also exposes Revenue at target utilisation, Actual billable revenue capacity. 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.
