Hi , The Usage dashboard - https://fivetran.com/account/usage/  currently show overall MAR and credits for the month selected for all Destinations . But  It also allow to pick the destinations from the drop down. But for individual destinations there is no sub total value showing , rather it show MAR for individual connectors.  If you have a lot of connectors its not practical to add all connector MAR numbers to calculate  the subtotal. The page should show total MAR usage for each connector when selected.
