AARP Projects 3.6% 2027 Social Security COLA as Inflation Picks Up

Q: Will rising Medicare premiums quietly erase the financial relief promised by the largest Social Security boost since 2023?

Not entirely, but they will noticeably shrink it for many retirees. Based on current estimates, Social Security benefits are on track to rise about 3.6% in 2027, which would add roughly $75 a month to the average retirement benefit of about $2,085. Medicare trustees, however, project the standard Part B premium will rise by $6.60 to $209.50. Because that premium is usually deducted directly from Social Security checks, the average net monthly gain would fall to about $68.46, reducing the effective increase from 3.6% to about 3.28%. So the projected Medicare increase would not erase the COLA, but it would quietly absorb part of it. For retirees with higher medical costs, drug expenses or Medicare surcharges tied to income, the real financial relief could feel even smaller than the headline COLA suggests. That is why advocates such as AARP argue the current COLA formula understates seniors’ inflation. Social Security uses CPI-W, which tracks spending by urban wage earners and clerical workers, not older households that spend more heavily on health care and prescriptions. If those categories rise faster than overall inflation, retirees can still lose purchasing power even in a year with a relatively strong COLA. There is also uncertainty. The official 2027 COLA will not be announced until Oct. 14, after September inflation data are released, and the final Medicare premium will come later. Oil prices and late inflation could still move the COLA slightly higher or lower.

AARP on Friday estimated a 3.6% Social Security cost-of-living adjustment for 2027 after July and August CPI-W data pointed to a bigger benefit increase next year.
The official COLA will be set on Oct. 14 using the average CPI-W readings for July through September, with one month of inflation data still to come.
If the forecast holds, the increase would top this year’s 2.8% adjustment and mark the largest since 2023, when the COLA was 3.2%; some analysts say higher oil prices could push it up further.
A 3.6% COLA would add about $75.06 to the average $2,085 monthly retirement benefit, though a projected $6.60 rise in Medicare Part B premiums would trim the net gain.
The estimate also revives criticism of the CPI-W formula, which many advocates say understates seniors’ costs, especially for health care and prescription drugs.
