The annual cost-of-living adjustment (COLA) for recipients of Social Security retirement and disability benefits is calculated every October using the Consumer Price Index. It’s done to keep rising costs for the things we buy from eroding the buying power of payments. And with inflation running near its hottest in 40-years, the COLA is following suit: This year’s adjustment is expected to add $144.10 to the average retirement payment of $1,656, the Senior Citizens League nonprofit group calculated this week. That’s the biggest percentage increase since 1982, as the chart below shows. One caveat: there is still one more month of inflation data to go before the figure is finalized, and with inflation having cooled in the last two months, it’s possible the COLA could drop a little further as well.  Have a question, comment, or story to share?
