THE NUMBERS, EXPLAINED
How to use this calculator.
Credit rates and cap are supplied agreement terms. Task completion counts instances equally rather than weighting by price or duration.
Start with your inputs
Enter scheduled task instances by type, missed task instances by type, agreed credit per missed task (currency), maximum credit for period (currency). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Scheduled task instances by type | 20,10 |
| Missed task instances by type | 2,1 |
| Agreed credit per missed task (currency) | 5,20 |
| Maximum credit for period (currency) | 100 |
A worked example
With the example inputs above, uncapped credit by task type (currency) is 10, 20. Change the inputs to explore your own scenario.
