SDCL §54-3-5.1 applies the fixed Category B rate—currently 10%—to its general judgment branch; it is not a periodically resetting formula. A lawful contract can control, inverse-condemnation awards follow a separate 4.5% branch, and excluded judgment categories require their own authority. Confirm the selected branch before calculating.
