Grant & Funding Calculators
Cost Per Beneficiary Calculator
Calculate the exact cost per beneficiary from total program cost and the number of people served, a standard efficiency metric used in grant reporting.
Funding Gap Calculator
Calculate the exact funding gap or surplus between total project cost and the funding already secured, along with the precise percent funded figure.
Grant Application Deadline Calculator
Calculate days remaining until a grant deadline and your recommended start date, based on how many days of prep the application actually requires.
Grant Budget Calculator
Split a total grant amount across personnel, program, administrative, and other budget categories by percentage, with the exact dollar figure for each.
Grant Disbursement Schedule Calculator
Generate a complete grant disbursement schedule with installment amounts and exact dates, at monthly, quarterly, semiannual, or annual frequency.
Grant ROI Calculator
Calculate grant ROI by comparing total value generated against the grant amount, showing net value and the exact return produced per dollar of funding.
Indirect Cost Rate Calculator
Calculate your indirect cost rate as a percentage of a chosen direct cost base, and compare it to the federal 10 percent de minimis rate option.
Matching Funds Calculator
Calculate the required matching funds for any grant-to-match ratio, plus the total project budget and match percentage, before committing to a proposal.
Overhead Rate Calculator
Calculate an organizations overhead rate as a percentage of direct costs, a figure commonly reviewed by grant funders and charity rating platforms.
Program Budget Calculator
Build a bottom-up program budget from personnel, supplies, travel, and other direct cost line items, with indirect costs calculated automatically.
The Numbers Funders Actually Scrutinize
Grant applications live or die on a handful of numbers reviewers check closely — whether the overhead rate looks reasonable, whether matching funds requirements are actually met, and whether cost per beneficiary suggests the program delivers real value for the money requested. These calculators work through the budget math that goes into a competitive grant application and its ongoing reporting.
Popular Grant & Funding Calculators
Ten tools span budgeting, compliance, and impact reporting:
- Grant Budget Calculator — builds a full program budget across personnel, direct costs, and indirect costs.
- Indirect Cost Rate Calculator — applies an approved indirect cost rate to direct costs for full-cost recovery.
- Matching Funds Calculator — calculates the matching contribution required to meet a grant's cost-share terms.
- Cost Per Beneficiary Calculator — divides total program cost by people served, a common impact and efficiency metric.
- Funding Gap Calculator — finds the shortfall between a program's budget and secured funding to date.
Why Indirect Cost Rates Cause So Much Confusion
An organization's indirect cost rate (covering overhead like rent, utilities, and administrative staff not tied to one specific program) is usually negotiated with a federal agency or set by policy, and applying it incorrectly — against the wrong cost base, or using an outdated rate — is one of the most common grant compliance errors. This matters because indirect costs aren't a flexible padding number: many grants cap the allowable indirect rate below an organization's actual negotiated rate, meaning the organization absorbs the difference rather than recovering full overhead cost on that particular grant.
Frequently Asked Questions
Is overhead rate the same as indirect cost rate?
They're closely related and often used interchangeably, though "overhead rate" sometimes refers more narrowly to administrative costs while "indirect cost rate" can include a broader, formally negotiated cost pool.
What happens if matching funds requirements aren't met?
Grantors can reduce the award, require a revised budget, or in some cases rescind funding, which is why matching funds calculations are typically confirmed before a grant is formally accepted, not after spending begins.
