Total Grant Amount or Amount from Government on CV
In the US, this kind of arrangement is called "cost sharing." Under current rules federal agencies are no longer allowed to require cost sharing and institutions cannot propose cost sharing, although this was sometimes required in the past.  

The way to describe this in a CV would normally be to give the amount of the award as one number, plus the amount of cost share as a second number.

e.g.

B. Borchers.  Searching for Tribbles in the Oort Cloud.  Extra Terrestrial Biology Funding Agency, 2015-2017.  $100,000 award plus $20,000 in institutional cost sharing.
