For a rotating black hole, the theoretical maximum fraction of mass-energy that can be radiated away when mass is accreted into it is about 20%. This is because the accretion process can convert a significant portion of the mass-energy into radiation, especially in the context of high-efficiency accretion disks around black holes.
