Agency Utilization uses productive hours, available hours.
Reading capacity and cost without hiding the workload
For agency utilization, the relationship is Result = (([Productive hours]) ÷ ([Available hours])) × 100. The amount depends on the supplied productive hours, available hours, rather than a live market price or a value imported from another record. A staffing plan needs available hours and the portion of those hours that can serve the intended work. Paid time, productive time and billable time are separate definitions. Recruiting, training and supervision can change the cost of a role.
What the model includes
Result = (([Productive hours]) ÷ ([Available hours])) × 100 Use one team and one reporting period. Headcount measures should distinguish people from full-time equivalents; hour-based models should state the expected schedule. A temporary absence and a permanent vacancy have different operating consequences. Review the result with the work queue and service commitment. A high utilisation percentage can signal limited room for urgent work, rather than a reason to add more demand immediately.
Example with the supplied inputs
Productive hours: 120; Available hours: 160. Result: 75.00%. The values are illustrative.
Compare one changed input
Productive hours changes from 120 to 132. The result becomes 82.50%. All other inputs remain fixed.
Calculation rule
Result = (([Productive hours]) ÷ ([Available hours])) × 100
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Productive hours | 120 | Use the duration unit stated in productive hours. A time period is not interchangeable with a currency amount or a count of events. |
| Available hours | 160 | Use the duration unit stated in available hours. A time period is not interchangeable with a currency amount or a count of events. |
Output: 75.00% is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Productive hours, Available hours. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Productive hours on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 75.00%.
Change Productive hours from 120 to 132 while keeping every other value fixed. The result becomes 82.50%. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
