From the Department of Retirement Systems:
A cost-of-living adjustment (COLA) is an annual adjustment applied to your retirement income to reflect changes in the economy (inflation). Most DRS retirement plans offer a COLA, but Plan 1 members in PERS and TRS only have a COLA if they selected it during retirement.
View the 2025 COLA percentages by retirement date and plan.
When will I receive the 2025 COLA?
COLAs take effect July 1 and start with July 31 benefit payments.
You need to be retired by July 1 for at least one year to be eligible for a COLA…
