1,152 is the example result. Read it using the units and relationship stated below.
Billable Hours uses hours per week, billable utilization, working weeks.
Reading capacity and cost without hiding the workload
For billable hours, the relationship is Result = [Hours per week] × ([Billable utilization] ÷ 100) × [Working weeks]. The amount depends on the supplied hours per week, billable utilization, 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 = [Hours per week] × ([Billable utilization] ÷ 100) × [Working weeks] 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
Hours per week: 40; Billable utilization: 60; Working weeks: 48. Result: 1,152. The values are illustrative.
Compare one changed input
Billable utilization changes from 60 to 66. The result becomes 1,267.2. All other inputs remain fixed.
Calculation rule
Result = [Hours per week] × ([Billable utilization] ÷ 100) × [Working weeks]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Hours per week | 40 | Use the duration unit stated in hours per week. A time period is not interchangeable with a currency amount or a count of events. |
| Billable utilization | 60 | Enter billable utilization on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
| Working weeks | 48 | Use the duration unit stated in working weeks. A time period is not interchangeable with a currency amount or a count of events. |
Output: 1,152 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 Hours per week, Billable utilization, Working weeks. 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 Billable utilization 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 1,152.
Change Billable utilization from 60 to 66 while keeping every other value fixed. The result becomes 1,267.2. 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.
