Understanding the Social Security COLA

The COLA is an annual adjustment that helps Social Security benefits keep upwith inflation. It’s calculated based on the increase in the Consumer PriceIndex for Urban Wage Earners and Clerical Workers (CPI-W) compared to the prioryear. If inflation increases compared to the previous year, then the COLA isapplied to increase benefits by a percentage in the next year to keep up withthose costs.

Since the COLA calculation is only based on the CPI-W data from the thirdquarter of each year, we haven’t yet seen the inflation data that could actuallyimpact the COLA. However, analysts are making predictions about the 2027 COLAbased on inflation in the first half of the year, and those predictions arequickly increasing.

The recent significant jump in COLA predictions

Early 2026 COLA predictions were somewhat modest. The Senior Citizens Leagueinitially predicted a COLA between 2.5% and 2.8%. Since the 2026 COLA was 2.8%,those predictions suggested that inflation would remain about the same,resulting in a similar COLA for 2027.

But new inflation data has sharply changed those estimates, promptingsignificantly higher COLA predictions. In March, inflation was at 3.3%, but itjumped to 3.8% in April, driving up COLA predictions, too.

What’s driving inflation

According to the U.S. Bureau of Labor Statistics, several factors are driving April’s 3.8% consumer price index. Energy pricesincreased by 3.8% month over month and accounted for about 40% of the inflation increase. As ofMay 7, the price of gas had increased by 52% compared to when the war with Iranbegan, according to American Automobile Association (AAA) data, driving up the cost of not only energy, but also food and goods.

The cost of food increased by 3.2% in April, while food at home prices increasedby 0.7%, which is the largest monthly gain the category has seen since August2022. Additionally, shelter costs increased by 0.6%, further contributing toinflation.

The Senior Citizens League’s COLA predictions

The new inflation data prompted the Senior Citizens League to revise its earlierCOLA prediction. While the Senior Citizens League initially projected a 2027COLA of 2.5% to 2.8%, now the organization predicts a significantly higher COLAof 3.9%. The fact that the organization revised its prediction suggests it’s likely that inflation could continue throughout the year, impacting thethird-quarter data that the official COLA calculation is going to utilize.

Mary Johnson’s COLA predictions

Mary Johnson, an independent analyst who has tracked the COLA for 30 years,initially projected a 1.2% COLA for 2027. But after the war with Iran began andgas and energy prices surged, Johnson revised the projection, predicting a COLAas high as 4.2%.

“This represents the highest rate of inflation since 2022 and a potentiallysignificant erosion in many consumers’ standard of living,” Johnson said.

The potential Social Security benefits increase

The current average monthly Social Security benefit for retired workers is$2,081.16. If the Senior Citizens League’s projection of a 3.9% COLA wereimplemented in 2027, average benefits would increase by $81.17 to $2,162.33.Retirees would receive about $974 more per year.

If Johnson’s projection of a 4.2% COLA were implemented, average monthlybenefits would increase by $87.41 to $2,168.57. With Johnson’s higherprojection, retirees would receive about $1,049 more per year.

What COLA means for retirees

A COLA increase may seem positive, since retirees would receive larger benefits.But the COLA is only designed to keep up with inflation, so retirees don’tnecessarily come out ahead.

The COLA calculation is only based on quarter three inflation data. If inflationcontinues to increase in quarter four, the COLA won’t reflect that higherinflation rate. Plus, the COLA is only adjusted once a year. Retirees alreadyrelying on Social Security have to cover increased costs, like grocery bills andutility expenses, that are being impacted by inflation right now. If inflationgrows throughout the entire year, retirees would have gone nearly a year coveringhigher costs on 2026 Social Security benefit amounts that haven’t increased.

Bottom line

There are still months of inflation data to review before the official COLAcalculation is made, so the final COLA amount could shift in either direction.The Social Security Administration should announce the COLA in October, and thenthe increase should begin with January 2027 Social Security checks.

A higher COLA may not offset retirees’ real cost pressures, especially sincemany finance and senior professionals have criticized the CPI-W for notaccurately reflecting retirees’ most common expenses, like health care.
