5 U.S.C. § 8112 — Maximum and minimum monthly payments

(a) This subsection limits how much money in disability compensation an injured federal worker can get each month, unless section 8138 of this title says otherwise. The monthly amount includes "augmented compensation" under section 8110, but not the extra "additional compensation" under section 8111. Here are the rules, step by step: Step 1: Find 75% of the highest monthly basic pay rate for GS–15. The worker's compensation cannot go above that amount. Step 2: For a worker who is totally disabled, find 75% of the lowest monthly basic pay rate for GS–2. Step 3: Compare that number to the worker's own actual monthly pay. The compensation floor is whichever of those two numbers is smaller — the worker's compensation cannot go below it. (b) Subsection (a) does not apply to an employee whose disability came from an assault. That assault must have happened during an assassination, or attempted assassination, of a federal official as described in section 351(a) or 1751(a) of title 18. The injury must also have happened while the employee was doing their job. For these employees, the cap and floor in subsection (a) do not apply.
