Grant Match Sources Calculator

Plan how to meet grant matching fund requirements using cash, in-kind donations, volunteer time, and partner contributions.

About this calculator

Many federal and foundation grants require your organization to contribute matching funds alongside the award, expressed as a ratio to the grant amount — enter 1 for a full 1:1 match or 0.25 for a 25% match, and the calculator multiplies that ratio by your grant amount to get the dollar figure you actually need to document. It then totals four match sources: direct cash contributions, in-kind donations valued at fair market value, volunteer time (converted to dollars using an hourly rate you set, defaulting to Independent Sector's published national estimated value of volunteer time for 2021, $29.95/hour), and contributions from partner organizations, plus an optional line for unrecovered indirect costs if your funder allows counting those toward match. Independent Sector republishes this figure every year and it has risen substantially since 2021, reaching $36.14/hour for 2025, so it's worth overriding the default with their current published rate — or with whatever rate your funder specifies — rather than relying on the figure shown here.

Volunteer time and other in-kind donations are combined into a single in-kind subtotal before being added to cash and partner contributions for the grand total. The tool then reports the surplus or deficit against the required match and the percentage of the requirement you've covered, plus a percentage breakdown of how much of your match is cash versus in-kind versus partner-sourced — useful because many funders cap how much of a match can come from in-kind sources. Keep in mind this tool takes your entered volunteer rate and donation values at face value; it doesn't validate that a given funder actually permits volunteer time, partner contributions, or unrecovered indirect costs as allowable match, so check your specific award's terms before finalizing commitments.

How to Use This Calculator
  1. Enter the Grant Amount and required Match Percentage from the funder.
  2. Enter proposed match sources: cash contributions, in-kind labor, donated materials, and facility space.
  3. Review the total match value and whether it meets or exceeds the required match.
  4. Check Allowable vs Non-Allowable match sources per the funder's guidelines.
  5. Use the analysis to document match commitments in memoranda of understanding with partners.

What each input means

Grant Award Amount ($)
Total amount of the grant you are applying for.
Match Ratio (e.g. 1 = 1:1)
Required match as a ratio of grant amount. 1:1 = 1.0, 25% match = 0.25.
Cash Match ($)
Direct cash contributions from your organization or donors.
Volunteer Hours
Donated volunteer hours to count as in-kind match.
Volunteer Hour Rate ($)
Value per volunteer hour (Independent Sector's 2021 national avg, $29.95; their current published rate is higher).
Other In-Kind Donations ($)
Donated goods, services, space, or equipment at fair market value.
Partner Contributions ($)
Cash or in-kind contributions from collaborating organizations.
Indirect Costs as Match ($)
Unrecovered indirect costs counted toward match (if allowed by funder).

What each result means

Required Match
Total matching funds needed based on grant amount and match ratio.
Total Match Identified
Sum of all match sources you've identified.
Surplus / Deficit
Positive = surplus; negative = still need more match.
Match % Achieved
How close you are to meeting the full match requirement.
Volunteer Time Value
Dollar value of volunteer hours at the given rate.
Total In-Kind Value
Volunteer time plus other in-kind donations.
Cash % of Match
Cash contributions as percentage of total match.
In-Kind % of Match
In-kind contributions as percentage of total match.
Total Project Budget
Grant award plus all match sources.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Grant Award Amount ($) = 100000, Match Ratio (e.g. 1 = 1:1) = 0.25, Cash Match ($) = 10000, Volunteer Hours = 200 = 8 input(s) provided
  2. Calculate Required Match
    Required Match = grantAmount * matchRatio
    25000 = $25,000
  3. Calculate Total Match Identified
    Total Match Identified = cashMatch + totalInKind + partnerContributions + indirectAsMatch
    20990 = $20,990
  4. Calculate Surplus / Deficit
    Surplus / Deficit = totalMatch - requiredMatch
    -4010 = $-4,010
  5. Calculate Match % Achieved
    84 = 84%

Frequently Asked Questions

How do I express a 25% match requirement versus a full 1:1 match?

Enter the match ratio as a decimal fraction of the grant amount: 1.0 means a full 1:1 match (you must match every dollar requested), while 0.25 means a 25% match (a quarter of the grant amount). The calculator multiplies whatever ratio you enter by your Grant Award Amount to get the dollar figure of required match you need to document.

How is volunteer time converted into a dollar value for the match?

Volunteer time value is your entered volunteer hours multiplied by an hourly rate, which defaults to $29.95 — Independent Sector's published national estimated value of volunteer time for 2021. Independent Sector updates this figure annually, and it has since climbed to $36.14/hour for 2025, so check their current published rate (or your funder's specified rate) and override the default if precision matters for your application.

Why does the calculator break out cash, in-kind, and partner percentages separately?

Many funders cap how much of a required match can come from in-kind sources (like volunteer time or donated goods) versus actual cash, so seeing the percentage split of your total match across cash, in-kind, and partner-sourced contributions helps you check whether you're relying too heavily on one category before those caps become a problem in your application.

Does the calculator verify that my funder allows volunteer time or indirect costs as match?

No — it takes whatever values you enter for volunteer rate, in-kind donations, partner contributions, and indirect costs as match at face value and simply totals them against the required match. It does not check your specific award's terms, so you still need to confirm with your funder's guidelines that each match source you're counting is actually allowable before finalizing commitments.
