Matching funds — also called cost-sharing — are a common grant requirement that trips up many applicants. Here's everything you need to know.
What Are Matching Funds?
Matching funds are your contribution to a grant-funded project. When a funder requires a "match," they're asking you to invest alongside them.
Example:
- Grant award: $100,000
- Required match: 25%
- Your contribution: $25,000
- Total project: $125,000
Types of Match
Cash Match
Actual dollars you spend:
- Direct organizational funds
- Other grants (if allowed)
- Donations specifically for this project
- Revenue from project activities
In-Kind Match
Non-cash contributions with monetary value:
- Staff time (at actual salary rates)
- Volunteer time (at fair market rates)
- Donated equipment or supplies
- Donated space or facilities
- Professional services
How to Calculate Match
The Formula
Match Amount = Grant Request × Match Rate ÷ (1 - Match Rate)
Or more simply:
| Match Requirement | Grant Request | Your Match |
|---|---|---|
| 10% | $100,000 | $11,111 |
| 20% | $100,000 | $25,000 |
| 25% | $100,000 | $33,333 |
| 50% | $100,000 | $100,000 |
Valuing In-Kind Contributions
Staff time:
Hourly rate × hours worked = Value Example: $30/hour × 100 hours = $3,000
Volunteer time: Use Independent Sector's value (~$30/hour for general volunteers, higher for professional services)
Donated goods: Fair market value (what you'd pay retail)
Donated services: What you'd pay for equivalent professional services
Donated space: Comparable rental rates in your area
Common Match Requirements by Funder
| Funder Type | Typical Match |
|---|---|
| Federal research (NIH, NSF) | 0-20% |
| Federal community grants | 25-50% |
| State programs | 10-50% |
| Private foundations | Varies (often none) |
| Corporate grants | Often none |
Strategies for Meeting Match
1. Leverage Existing Resources
What you're already spending that relates to the project:
- Staff time on related activities
- Office space used for project
- Equipment already owned
- Utilities, insurance, overhead
2. Secure Partner Commitments
Other organizations contributing to your project:
- Partner staff time
- Shared facilities
- Collaborative services
- Subgrant from another funder
3. Value Volunteer Time
Track volunteer hours carefully:
- Create sign-in sheets
- Document activities
- Apply appropriate hourly rates
- Keep contemporaneous records
4. In-Kind Donations
Solicit goods and services:
- Professional services (legal, accounting)
- Supplies and materials
- Equipment loans
- Space donations
5. Other Funding Sources
Layer multiple grants (when allowed):
- Foundation grants
- Corporate sponsorships
- State programs
- Fee revenue
Documentation Requirements
You MUST document match carefully:
For Cash Match:
- Bank statements
- Cancelled checks
- Accounting records
- Grant agreements from other funders
For In-Kind Match:
- Timesheets for staff/volunteers
- Donation letters with values
- Market rate documentation
- Photos of donated goods
For All Match:
- Contemporaneous records (not reconstructed later)
- Clear connection to the project
- Verification that costs are allowable
- Evidence match is from non-federal sources (for federal grants)
Common Mistakes
❌ Double-counting match Can't use same match for multiple federal grants
❌ Using federal funds as match Federal money can't match federal money (with few exceptions)
❌ Unallowable costs Match must meet same cost principles as grant funds
❌ Poor documentation Must be verifiable if audited
❌ Overvaluing in-kind Use realistic, defensible valuations
What If You Can't Meet Match?
Options:
1. Request a waiver Some programs allow match reduction for hardship
2. Phase the project Smaller project = smaller match
3. Find partners Share match burden with collaborators
4. Apply elsewhere Some funders don't require match
5. Build match over time Multi-year projects can spread match
