Grant cost sharing—also called matching or co-financing—is the part of an eligible project cost that the donor does not pay. Your organization, a partner, another funder or an approved third party covers that share in cash, eligible in-kind support or a combination allowed by the call. The important question is not whether cost sharing “looks committed.” It is whether the contribution is required, affordable, documented and allowed by the specific grant rules.
This guide is written for African NGOs, CBOs, churches and social enterprises reviewing grants from governments, foundations and international agencies. Terminology varies by donor, so always treat the call, budget template and grant agreement as the controlling documents.
Cost sharing, matching and co-financing: are they the same?
They often describe the same basic idea: the funder pays only part of the project cost. The language and calculation can differ:
- Cost share usually means the portion of project costs borne by the applicant or another non-donor source.
- Matching funds usually means a defined contribution that must match donor funding at a stated ratio, such as 1:1 or 20%.
- Co-financing is common in international and EU-style funding and describes financing from sources other than the grant.
Grants.gov defines matching or cost-sharing requirements through the specific opportunity, while European Commission guidance notes that a call or contract may set a co-financing rate. These are useful reference points, but they are not universal rules for every African or private foundation grant.
The five-gate test before you accept a cost-share requirement
1. Obligation: is the contribution mandatory?
Read the eligibility, budget and award sections separately. A contribution may be mandatory, optional, encouraged, capped or prohibited. Do not volunteer a match simply because it seems competitive. A voluntary commitment can become an enforceable award obligation.
2. Source: what can count?
Confirm whether the donor accepts unrestricted organizational funds, another grant, local government support, partner cash, donated facilities, volunteer time, equipment use or other in-kind contributions. Some programmes prohibit using one donor’s funds as match for another. Others accept only contributions committed for the same project period.
3. Timing: when must the contribution exist?
Distinguish money already in the bank from a pledge, expected income and support to be raised after award. Ask whether the application needs evidence of commitment, whether the full amount must be secured before contracting, and when contributions may be spent or recognized.
4. Evidence: how will you prove it?
A credible contribution has an owner, amount, source, date, restriction and supporting document. Depending on the donor, evidence may include a board resolution, signed commitment letter, bank statement, partner agreement, payroll record, invoice, timesheet, valuation method or receipt. A line in the budget is not evidence by itself.
5. Capacity: can the organization carry it without harming operations?
Test cash flow, not only the final budget. If the donor reimburses costs after expenditure, your NGO may need to finance both the cost share and the donor-funded portion temporarily. A technically affordable match can still create a payroll, procurement or delivery crisis.
Worked example: calculate the contribution correctly
Assume an eligible project budget of KES 10,000,000 and a donor financing rate of 80%.
- Eligible project cost: KES 10,000,000
- Donor share at 80%: KES 8,000,000
- Required co-financing at 20%: KES 2,000,000
The KES 2,000,000 is not automatically “cash required.” The call may allow, limit or exclude in-kind support. If the NGO proposes KES 1,200,000 in cash and KES 800,000 in donated facilities or services, it must verify that both categories are eligible and that the valuation method is acceptable.
Also check the denominator. Some calls calculate the percentage against total eligible project costs; others express the donor contribution as a percentage of eligible costs or state a fixed grant amount. Copy the donor’s formula before building the budget.
Questions to ask before your team says yes
- Is the match mandatory for eligibility or only considered during evaluation?
- What is the exact rate, amount and calculation base?
- Which cash and in-kind sources are eligible?
- Can another donor’s funds be used, and has that donor agreed?
- What proof is required at application, contracting and reporting stages?
- Does the contribution have to be additional, or can existing staff time and assets count?
- What happens if a pledged partner contribution is late or withdrawn?
- Can the organization cover the required cash flow without diverting restricted funds?
Common mistakes
- Promising first and verifying later. A partner’s verbal support is not a committed contribution.
- Double counting. The same staff time, vehicle or donated space cannot be charged to two projects for the same period.
- Using inflated in-kind values. Use a reasonable, documented method that the donor permits.
- Ignoring reporting effort. Cost-share records may be reviewed with the same care as grant-funded expenditure.
- Treating match as free money. Contributions still consume cash, staff time, assets or partner capacity.
A practical go, hold or no-go decision
GO when the source is eligible, documented, affordable and controlled. HOLD when the source is plausible but not yet committed or the calculation is unclear. NO-GO when the match depends on restricted funds you cannot use, unsupported pledges, double counting or cash flow your organization cannot carry.

Frequently Asked Questions
What is grant cost sharing?
Cost sharing is the portion of project costs that must be covered from sources other than the donor’s contribution.
What is co-financing?
Co-financing generally refers to additional funding or resources contributed alongside the main donor award to support the same project or objective.
Can the same contribution be counted twice?
No. A contribution should not be claimed against more than one funding requirement unless donor rules explicitly permit it.
How should NGOs track cost share?
Use a separate schedule or ledger that identifies the source, amount, date, evidence and related project activity.
What happens if the required contribution is not met?
The organization may face reduced reimbursement, noncompliance or other consequences depending on the award terms, so shortfalls should be identified and escalated early.
Conclusion
Cost sharing and co-financing create obligations that need the same level of control as donor-funded expenditure. NGOs should confirm eligible sources, avoid double counting and maintain a clear record of every contribution used to satisfy the funding requirement.
