How was the 2023 COLA calculated?
MPERS calculates annual COLAs according to statutory guidelines set out in RSMo
104.103.5 and
104.1045.2 and uses data from the Consumer Price Index for All Urban Consumers (CPI-U).
The chart below shows the annual average of the CPI-U during 2021 was 270.970 and is subtracted from the annual average of the CPI-U for 2022 of 292.655, for a difference of 21.865. This difference is then divided by the CPI-U average from 2021 (270.970).
The result of that calculation is 8.003%, which is the percentage of increase from 2021 and 2022. Missouri statutes state the COLA amount will be 80% of the percentage increase in the CPI-U. The final calculation takes the percentage increase of 8.003% and multiplies it by 80% which equals 6.402%.
The MPERS COLA amount is capped at a maximum of 5%, therefore during 2023, all eligible retirees and payees will receive a 5% COLA.
