The early read on next year’s Social Security raise is now 3.6 percent, and on the average retirement check that works out to roughly $70 more a month. It would be the biggest cost-of-living bump in a few years, larger than the 2.8 percent that took effect this January. But the figure is an estimate, not a decision, and the gap between the two matters for anyone budgeting around it.
Where the 3.6 percent number comes from
The projection is the work of The Senior Citizens League, a nonpartisan advocacy group that tracks the inflation data the raise is built on and updates its forecast every month. After the August 12 release of the July inflation report, the group revised its 2027 estimate to 3.6 percent, down slightly from a higher figure earlier in the summer as inflation cooled. In its own update on the projection, the League notes that two months of data are still missing, so the final number can move in either direction.
Applied to the average retired-worker benefit, a 3.6 percent adjustment amounts to about $69.75 a month, lifting the typical check from roughly $1,937.53 to about $2,007.28. That is the arithmetic behind the headline: a raise that finally carries the average benefit just over the $2,000 mark.

Nothing is official until October 14
The raise is not set by a forecast or a vote. It is set by a formula, and the formula is not finished running yet. Social Security calculates the annual cost-of-living adjustment from the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W, averaged across July, August, and September and compared with the same three months a year earlier. Only after the September inflation figure is published can the agency lock in the percentage.
That is why the Social Security Administration has scheduled the official 2027 announcement for October 14, 2026. Until then, every number in circulation — including 3.6 percent — is a running estimate, and competing forecasts from other analysts have landed a few tenths of a point apart after the same inflation data. The one to plan around is the one the agency publishes in October.
Why a bigger raise does not always feel like one
A 3.6 percent increase sounds like real money, and $70 a month is. But the cost-of-living adjustment is designed to keep pace with prices, not to get ahead of them, so its purpose is to hold a fixed income steady against inflation rather than to expand it. When the raise arrives, some of it is often absorbed before it reaches the bank account.
The most common offset is Medicare. The standard Part B premium is deducted directly from most Social Security checks, and when that premium rises, it eats into the raise. In years when the Part B increase is steep relative to the COLA, beneficiaries have seen much of their bump disappear before it ever showed up as spendable income. The 2027 Part B premium is set separately and later in the fall, so the net raise — what actually lands after the Medicare deduction — will not be clear until both numbers are final.
There is also a protection worth knowing about for years when the two numbers collide. The Social Security “hold harmless” provision generally prevents a rise in the standard Part B premium from actually reducing most beneficiaries’ net Social Security checks from one year to the next. It does not apply to everyone — higher-income enrollees who pay income-related premium surcharges are outside it, and it does not stop the premium from eating into a raise — but for many retirees it means the raise may be trimmed without the underlying check falling below what it was.
What to do with the estimate between now and October
For planning, the honest move is to treat 3.6 percent as a placeholder and avoid committing the extra money before it is confirmed. A retiree deciding whether a raise covers a rent increase or a higher insurance premium is better served waiting for the October 14 figure and the Part B premium than banking on a projection that has already moved twice this summer.
The estimate is still useful as a direction. After a 2.8 percent raise this year, the trend line points to a somewhat larger one next year, which is meaningful for households where the monthly check is the budget. But The Senior Citizens League itself frames the 3.6 percent as a forecast with two data points outstanding — a number worth watching, not one to spend, until the CPI-W for September closes the calculation and the agency makes it official.
