Cost share is the portion of total project costs that are paid from sources other than the sponsor. Cost share is either dictated by the sponsor in the proposal solicitation (mandatory cost share) or is a voluntary contribution shown to the sponsor in the proposal budget. Once the cost share is shown to the sponsor in a proposal budget, Michigan Tech is obligated to identify and track the cost share expenditures.
Here are the university’s practice for cost share on sponsored projects as well as the sources for cost share.
