Cost-of-Living Adjustments (COLAs)
Eligible service and disability retirees may receive cost-of-living adjustments (COLAs) on monthly benefits beginning the fourth January following their retirement date. For example, if you retire any month in 2018, you will become eligible for COLAs in January 2022. Qualified beneficiaries may also receive COLAs.
The January 2018 COLA is 1.63%. Current Missouri law states that COLAs cannot exceed 5% per year and the dollar amount of the COLAs in your lifetime cannot exceed 80% of your original monthly retirement benefit.
