Your Social Security check already got bigger once this year. The average retirement benefit climbed from $2,015 to $2,071 a month in January, a 2.8% raise that most retirees watched evaporate fast once Medicare took its cut.
Now three different research groups are penciling in next year’s number, and all three estimates land well above that 2.8%. AARP’s latest projection sits at 3.6%, and even the lowest of the three would still be the biggest raise retirees have gotten since 2023.
Nothing is final until the Social Security Administration announces the real number on October 14, once September’s inflation data closes out the calculation.

The new estimates already beat this year’s raise by a wide margin
Three different groups publish Social Security COLA forecasts every month once summer inflation data starts rolling in, and right now their numbers cluster in a tight band. The lowest of the three, from the Committee for a Responsible Federal Budget, comes in at 3.4%. The highest, AARP’s 3.6% projection, sits at the top of the range. In between is the Senior Citizens League’s latest figure of 3.5%, a notch down from the 3.6% it had projected a month earlier.
All three numbers run well ahead of last year’s raise. The 2026 COLA landed at 2.8%, and 2025’s came in at 2.5%, so even the low end of this year’s range marks the sharpest jump retirees have seen in a couple of years. A 3.4% to 3.6% raise would also be the largest annual Social Security increase since 2023, when inflation was running far hotter than it is now.
The reason three groups put out three slightly different numbers comes down to timing and methodology, not disagreement about the underlying inflation data. Each one updates its model every time a new monthly inflation report drops, and each weighs the still-missing September figure a little differently. That’s also why the estimates move around from month to month instead of sitting still. A retiree checking back in October will likely see the range narrow even further as the final puzzle piece falls into place.
The real number isn’t locked in until the September inflation report lands
The COLA formula is mechanical, not political. The Social Security Administration takes the average CPI-W reading for July, August, and September and compares it to the same three months a year earlier. Whatever that percentage works out to becomes next year’s raise, no rounding tricks and no congressional vote required.
Right now, researchers only have two of those three months in hand. August’s CPI-W came in up 3.5% from a year earlier, which is why the current estimates cluster where they do. September’s reading, due out alongside the official COLA announcement on October 14, is the only piece still missing. A sharp move in gas or grocery prices during that one month could still push the final number outside the 3.4% to 3.6% range, though a dramatic swing this late in the year would be unusual.
These estimates have already moved once this year. Midsummer readings had one projection running as high as 3.8%, and they’ve eased down toward the mid-3% range as inflation cooled slightly in July and August. That drift lower is actually a small piece of good news, since a smaller COLA usually tracks with slower price growth elsewhere in a retiree’s budget, even if it means a smaller check bump than the early estimates suggested.
What a raise in this range actually adds to a check
The exact dollar figure depends on which estimate you use and which starting benefit it gets applied to. Using the current average retired worker benefit of $2,071 a month, a 3.6% raise works out to roughly $75 more each month. Apply the lower 3.4% estimate to that same starting point and the increase drops to about $70.
The Senior Citizens League’s own figures use a slightly different starting benefit, which is why its numbers come out differently even at a similar percentage. Using its baseline average benefit of $1,940.08, a 3.5% raise would bring the monthly check to $2,007.98, a gain of $67.90.
Either way, the shape of the story stays the same. A raise in the 3.4% to 3.6% range would be the biggest cost of living increase retirees have seen since 2023, landing on top of two years of comparatively modest raises. An extra $70 or so a month isn’t life changing on its own, but it’s real money, and it’s noticeably more than the roughly $56 bump most retirees saw this January.
Medicare premiums take a slice before the raise reaches your account
Most retirees never see the full COLA, because Medicare Part B premiums come straight out of the check before it gets deposited. For 2027, the standard Part B premium is projected at $209.50 a month, up from $202.90 in 2026, an increase of about $6.60.
That’s actually good news by recent standards. The projected rise would be the smallest percentage increase in the Part B premium since 2023, and it was lowered from an earlier projection that had put 2027’s premium at $218.60. Against a COLA somewhere between 3.4% and 3.6%, a roughly $6.60 premium increase takes a smaller bite out of the raise than it has in some recent years, when premium increases outran the COLA itself and left some retirees with a smaller net check despite the official bump.
The official 2027 premium won’t be confirmed until November, and this projection has missed before. Budget around $209.50 for now, and expect the real figure to land close to it rather than exactly on it.
Why many seniors say the raise still won’t be enough
COLA increases get calculated using CPI-W, which tracks the spending patterns of working age, urban wage earners rather than retirees. That mismatch is a long running complaint among seniors’ advocates, since retirees spend a bigger share of their budget on healthcare and housing, two categories that have been rising faster than the basket CPI-W actually measures.
The frustration shows up in survey numbers too. In a June survey, 89% of seniors said the 2026 raise of 2.8% left their benefits short of covering inflation, even though that raise sat above the 20 year average Social Security COLA of 2.6%. And the stakes keep climbing: an estimated 24.8 million older Americans, about 44% of retirees, now say Social Security is their only source of retirement income, up from 39% a year earlier.
None of that changes how the 2027 estimate gets calculated, but it explains why a raise that looks generous on paper, the biggest in several years, still won’t cover rent, groceries, and medical bills that have been climbing just as fast.
The real figure arrives on October 14, once September’s inflation data is final. Wherever it lands within the 3.4% to 3.6% range on the table right now, 2027 is already shaping up to be the best raise most retirees have gotten in a few years.
