Cost-of-Living Adjustments (COLAs)

COLA Percentages 2018

Posted 3-9-2018

Note: A new law (SSB 6340) provides certain retirees of PERS Plan 1 and TRS Plan 1 a one-time increase to their monthly benefit in July 2018. See this What's New article for details.

Cost-of-Living Adjustments (COLAs) have been set for 2018. LEOFF Plan 1 COLAs will take effect April 1 and will be reflected in end-of-April benefit payments. COLAs for all other plans will take effect July 1 and will be reflected in end-of-July benefit payments.

The tables below show the 2018 COLA percentages based on your retirement date and plan. (Looking for COLAS from the previous year? See the 2017 COLA percentages table.)

Most COLAs are based on changes in the Consumer Price Index for the greater Seattle area. For more information about COLAs, annual increases and minimum benefits, visit the Frequently Asked Questions page.
