Skin in the Game: Why Funders Require Cost Share

A cost share requirement obliges a grant recipient to contribute a portion of a project's cost from its own resources. Beyond simply stretching a funder's money, cost share is a commitment device — a way of ensuring the recipient has genuine stakes in the project's success, with roots in the economics of accountability.

More Than Stretching Dollars

Like matching, cost share leverages a funder's contribution by requiring the recipient to add its own. But its deeper purpose is commitment: a recipient with its own money and resources on the line has powerful reasons to see the project succeed, manage it carefully, and follow through. Cost share turns a passive grantee into an invested partner.

Reducing Moral Hazard

Economists describe “moral hazard” — the risk that someone spending entirely other people's money takes less care than they would with their own. Requiring cost share is a direct counter: with its own funds committed, the recipient bears part of any waste or failure, sharpening its incentive to spend wisely. Shared cost means shared consequences.

Cash and In-Kind

Cost share need not always be cash. Many funders allow in-kind contributions — donated staff time, volunteer hours, facility use, or equipment valued at fair rates — to count toward the requirement. This lets organizations meet their obligation partly through resources they already have, though what qualifies and how it must be documented varies strictly by funder.

An Ongoing Obligation

Crucially, cost share is not just a box ticked at application time; the contribution must actually materialize and be documented throughout the grant. Failing to meet it during the project can jeopardize funding or trigger repayment. This is why cost share is best understood as a genuine, tracked commitment — the recipient's real stake in the work, honored to the end.
