Nonprofit Grant Overhead Calculator
Calculate your true indirect cost rate, allocate overhead across grants correctly, and stay compliant with funder requirements.
Nonprofits must allocate indirect costs accurately across grants and programs. Under-allocating overhead means your organization absorbs costs it should recover. Over-allocating risks compliance issues and funder penalties. Our calculator helps you find the correct rate.
How It Works
Enter your total expenses, direct program costs, and indirect costs. We calculate your indirect cost rate, model allocation across grants, and compare your rate to the federal de minimis rate.
Input Your Data

Costs directly attributable to programs

How We Calculate
Indirect Cost Rate = Indirect Costs ÷ Direct Costs × 100. Federal de minimis rate: 10% of modified total direct costs. Unrecovered Overhead = Indirect Costs - (Direct Costs × Min(Your Rate, Funder Cap)).

Frequently Asked Questions
What is the federal de minimis indirect cost rate?
The federal de minimis rate is 10% of modified total direct costs. Organizations that have never had a negotiated indirect cost rate can use this rate without a cost rate proposal.
How do funders view overhead costs?
Views are evolving. While some funders still cap overhead at 10-15%, many now recognize that adequate overhead is essential for effective programs. The trend is toward more realistic indirect cost recovery.
How does AP automation help with grant compliance?
AP automation automatically tags expenses to the correct grant and cost category, maintains a complete audit trail, generates funder-ready reports, and prevents over-allocation through real-time budget tracking.
