450 is the example result. Read it using the units and relationship stated below.
Overtime uses base hourly rate, overtime premium above base (%), overtime hours.
Reading capacity and cost without hiding the workload
For overtime, the relationship is Result = [Base hourly rate] × (1 + [Overtime multiplier] ÷ 100) × [Overtime hours]. The amount depends on the supplied base hourly rate, overtime premium above base (%), 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 = [Base hourly rate] × (1 + [Overtime multiplier] ÷ 100) × [Overtime hours] 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
Base hourly rate: 25; Overtime premium above base (%): 50; Overtime hours: 12. Result: 450. The values are illustrative.
Compare one changed input
Overtime premium above base (%) changes from 50 to 55. The result becomes 465. All other inputs remain fixed.
Calculation rule
Result = [Base hourly rate] × (1 + [Overtime multiplier] ÷ 100) × [Overtime hours]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Base hourly rate | 25 | Use the source quantity represented by base hourly rate. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Overtime premium above base (%) | 50 | Enter overtime premium above base (%) 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. |
| Overtime hours | 12 | Use the duration unit stated in overtime hours. A time period is not interchangeable with a currency amount or a count of events. |
Output: 450 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 Base hourly rate, Overtime premium above base (%), Overtime 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 Overtime premium above base (%) 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 450.
Change Overtime premium above base (%) from 50 to 55 while keeping every other value fixed. The result becomes 465. 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.
