THE NUMBERS, EXPLAINED
How to use this calculator.
The entered rate applies only to direct costs minus supplied exclusions. This does not interpret grant eligibility or negotiated rate rules.
Start with your inputs
Enter total direct costs (currency), costs excluded from indirect base (currency), supplied indirect rate (%). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Total direct costs (currency) | 10000 |
| Costs excluded from indirect base (currency) | 2000 |
| Supplied indirect rate (%) | 25 |
A worked example
With the example inputs above, eligible indirect-cost base (currency) is 8,000. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Eligible indirect-cost base (currency) | 8,000 |
| Indirect costs (currency) | 2,000 |
| Total grant budget (currency) | 12,000 |
How this is calculated
Eligible indirect-cost base (currency)
Subtract excluded direct costs.
Indirect costs (currency)
Apply supplied rate to eligible base.
Total grant budget (currency)
Add direct and indirect costs.
