NOTE: On August 11, 2011 the California Supreme Court in Baker v W.C.A.B. (XYZZX) (previously Duncan v W.C.A.B.) ruled that COLA’s be calculated and applied pro­spec­tively commencing on the January 1 following the date on which the injured worker first becomes entitled to receive, and actually begins receiving, such benefit payments, i.e., the permanent and stationary date in the case of total permanent disability benefits, and the date on which partial permanent dis­ability benefits become exhausted in the case of life pension payments. This calculator has been re-calibrated to accommodate this ruling.
