For millions of Americans relying on Social Security, the expected 2027 cost-of-living adjustment looks like welcome news at first glance. Current estimates put next year’s COLA between 3.4% and 3.6%, according to independent analyst Mary Johnson and the Senior Citizens League. That would be higher than the 2.8% increase applied in 2026 and could mean roughly $70 more a month for a recipient receiving an average benefit.
But there is an uncomfortable catch: a larger COLA is also a reminder that prices are still rising. Social Security’s COLA is designed to protect the purchasing power of benefits by reflecting inflation, using the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. In other words, when inflation stays elevated, the government generally has to provide a larger increase simply to help recipients keep up.
That creates the good-news, bad-news situation facing retirees. A 3.4% increase would put more money into monthly bank accounts, but it does not necessarily mean beneficiaries will feel 3.4% better off. Housing, food, insurance, healthcare and other essential expenses can rise at different rates, and many older Americans spend a larger share of their income on healthcare than the broader population.
There is another potential problem. Medicare Part B premiums are deducted from Social Security payments for many beneficiaries, meaning an increase in Medicare costs could absorb part of the COLA. The headline increase in the benefit therefore may not match the amount that actually reaches a retiree’s pocket.
The final number is still not known. The Social Security Administration calculates the adjustment using inflation data from July, August and September, with the official 2027 figure expected in October.
For retirees, the real question is not simply how big the COLA will be, but whether it will be big enough to keep pace with the cost of living.
