How is SERS’ COLA Calculated?

As we mentioned in our September 23 story and latest issue of Retiree Focus, the Board unanimously voted to approve a 0.5% cost-of-living adjustment (COLA) for eligible retirees and beneficiaries in 2021. Previously, COLAs were suspended from 2018 through 2020.

You may be curious how SERS calculated the 2021 COLA and why ours differs from Social Security’s COLA percentage.

In calculating the annual COLA, SERS compares the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) at June of the preceding year to the June CPI-W figure of the current year, capped at 2.5%. The CPI-W in June of 2019 was 249.747 and the CPI-W in June 2020 was 251.054, an increase of 0.5%.

In contrast, Social Security compares the average CPI-W across the preceding year’s third quarter to that of the current year’s third quarter. For this year, the increase was 1.3%. Social Security describes their calculation in further detail on their website.

You are eligible to receive a COLA if you began receiving your SERS benefit before April 1, 2018. If you began receiving your SERS benefit on or after April 1, 2018, you must wait until the fourth anniversary of your allowance before you are eligible to receive a COLA.

Not all benefit recipients will receive the 0.5% COLA because some will still be in their waiting period.

If you are eligible to receive a COLA on your SERS service pension or disability allowance, and you also receive a Social Security benefit based on a spouse, ex-spouse, or deceased spouse’s work record, you must report your COLA to Social Security.
