Cost Share is the portion of a project or program cost not borne by the sponsor. It is the University's share in the cost of conducting the project / program. Cost sharing occurs either when a sponsor requires, or the University commits in a proposal, funds beyond those awarded by the sponsoring agency to support a particular grant or contract.

Cost sharing may be required by federal or non-federal sponsors, and the obligation must be met using non-federal funds. Only charges that would be allowable as direct costs to the award are allowable as cost sharing. (Non-federal may be more flexible). Federal flow through funds may not be used as a cost sharing source unless prior written approval has been received from both the federal sponsor and the flow through sponsor.

The "cost share" pledge may be either a fixed amount of money, or a percentage of the project costs, or the commitment of a specified level of effort. The term "cost matching" often refers to cost sharing where the amount required as cost share is equal to the amount received from the sponsor. This is also known as dollar-for-dollar cost sharing or matching.
