How can I tell if we have met the cost share requirements on a particular budget?

It depends on the cost share requirements from the sponsor and/or what the PI proposed to the sponsor.

At the bottom of the Cost Share Summary application there is a column showing the total pledged dollar amount and another showing the actual total cost share dollars. Cost Share is considered met when the documented Cost Share actuals in the Cost Share Summary satisfy the sponsor’s requirements or meet the cost share commitments in the proposal budget.

Review the award documentation in conjunction with the Cost Share Summary application to determine if the pledged cost share requirement has been met.
