For every dollar a team is under the cap they lose $2 in revenue sharing.

"In Major League Baseball, 48% of local revenues are subject to revenue sharing and are distributed equally among all 30 teams, with each team receiving 3.3% of the total sum generated. As a result, in 2018, each team received $118 million from this pot. Teams also receive a share of national revenues, which were estimated to be $91 million per team, also in 2018."
