Every fall, tens of millions of retirees wait to learn how much bigger their Social Security check will be, and the early forecasts are starting to come in. One closely watched estimate now puts the 2027 cost-of-living adjustment near 3.6 percent, which would add roughly $70 a month to the average retiree’s benefit. It is an encouraging number for households living on a fixed income, but it is a projection, not a decision, and the real figure will not be set until October.
Where the 3.6% estimate comes from
The projection comes from The Senior Citizens League, an advocacy group that tracks the inflation data the adjustment is based on and updates its forecast as new numbers arrive. As relayed by CBS News, the group’s latest estimate of about 3.6 percent would raise the average retiree benefit from roughly $1,938 a month to about $2,007, an increase in the neighborhood of $70. The estimate rises and falls with each month’s inflation report, so a number floated in late summer can shift before the season is out. Retirement group AARP has similarly noted that the official announcement is still weeks away. Treat the 3.6 percent as a well-informed forecast, useful for planning, not as a figure you can bank on to the dollar.

How the official number gets set
The cost-of-living adjustment is not chosen by a person deciding retirees deserve a raise; it is calculated from a specific inflation measure. The Social Security Administration bases the COLA on the Consumer Price Index for Urban Wage Earners and Clerical Workers, comparing the third quarter of this year, July through September, with the same quarter a year earlier. Because September’s inflation figure is part of that formula, the agency cannot finalize the adjustment until that data is published. The official 2027 COLA is expected to be announced on October 14, 2026, and whatever it turns out to be will take effect with benefits payable in January 2027. That is why every projection before mid-October is exactly that, a projection built on partial data.
The Medicare premium that can eat the raise
A COLA headline can be misleading, because the increase you see on paper is not always the increase you feel in your bank account. Most retirees have their Medicare Part B premium deducted directly from their Social Security benefit, and when that premium rises, it takes a bite out of the raise before the money reaches you. In years when the Part B premium climbs sharply, a healthy-sounding COLA can shrink to a modest net gain once the higher premium is subtracted. The Part B figure for 2027 will also be announced in the fall, so the honest way to read a COLA forecast is to remember that your take-home increase depends on both numbers, not just the cheerful one. Until both are official, the net effect on your check is an estimate on top of an estimate.
What to do with a forecast, not a fact
A projection is still useful if you treat it as a planning tool rather than a promise. If you are mapping out next year’s budget, it is reasonable to pencil in a raise in the low-to-mid single digits while leaving room for the final number to come in higher or lower, and for a Medicare premium to offset part of it. Avoid committing to new fixed expenses based on a raise that has not been announced. When the official figures land in October, you can confirm your actual new monthly benefit through your personal my Social Security account, which posts your COLA notice and updated payment amount. The forecast tells you which direction things are heading; the October announcement tells you what to actually count on.
How a 3.6% raise would stack up against recent years
Context helps make sense of the projection. Cost-of-living adjustments swing with inflation, so they have ranged from tiny to large in just the past few years. The adjustment was 8.7 percent for 2023, an unusually big jump driven by the inflation spike of that period, then eased to 3.2 percent for 2024 and 2.5 percent for 2025 as inflation cooled. Against that backdrop, a figure near 3.6 percent for 2027 would be a return to a somewhat larger raise than the most recent year, which tracks with inflation data that has firmed up rather than kept falling. For a retiree, the practical meaning of the percentage is simple: it is applied to your own benefit, so a raise near 3.6 percent adds roughly $36 a month for every $1,000 you currently receive, before any Medicare premium is subtracted. Someone collecting close to the average benefit would see something in the neighborhood of $70, while a person with a larger benefit would see proportionally more. The exact figure still waits on the September inflation report, but the range gives you a reasonable band to plan within.
