OPERS announces COLA for 2027

Inflation-based adjustment to be 3.0%, based on government statistics

July 23, 2026 – Cost-of-living adjustments for all eligible OPERS members in 2027 will be 3%.

While those with a benefit effective date prior to Jan. 7, 2013, automatically receive a 3% adjustment, those with an effective date after that date have their COLAs based on the Consumer Price Index-W, the government’s inflation index for urban wage earners and clerical workers.

According to state law, the annual COLA for those retirees is to be based on the change in the CPI-W from the end of June 2025 to the end of June this year, with a maximum adjustment of 3%. The U.S. Bureau of Labor Statistics reports that the CPI-W increased 3.5% over that period, so OPERS’ CPI-based COLA for 2027 will be 3.0%. For reference, click on “CPI-W, June 2026” on this page of the Bureau of Labor Statistics website and refer to cell AD-7 in the spreadsheet.

OPERS’ inflation-based COLA uses the same index as Social Security. But the time period measured is different, so the adjustments might not always match up.

The adjustment is calculated on recipients’ original monthly benefit and is paid on the anniversary of their benefit effective date.
