Every summer the guessing game begins: how big will next year's benefit increase be? The early read on the Social Security raise 2027 will bring — officially called the cost-of-living adjustment, or COLA — points to 3.8 percent. That projection comes from The Senior Citizens League, a nonpartisan group that tracks the numbers all year long.

A projection is not a promise, and this one can still move. But it is a useful planning number, and the story behind it is worth a few minutes of your time.

The Social Security raise 2027 could deliver: about $74 a month

The Senior Citizens League estimates that a 3.8 percent adjustment would lift the average monthly benefit by roughly $73.62 — from about $1,937.53 to about $2,011.15. Your own raise depends on your own benefit amount; a larger check gets a larger dollar bump.

For context, this year's increase was 2.8 percent. If the projection holds, next year's raise would come in a full percentage point higher. Either way, the percentage applies across the board, so every benefit check in the country rises by the same share.

Why does one percentage point matter so much? Because the COLA touches nearly every retiree's budget at once — groceries, utilities, premiums, everything. It is the one raise most retirees receive all year, which is why the summer projections draw so much attention.

Where the number comes from

No committee decides what retirees deserve. The COLA comes from a formula. It compares inflation — measured by a version of the Consumer Price Index called the CPI-W — during July, August, and September of this year against the same three months last year.

Because that measuring window is still open, every new inflation report nudges the estimate. The projection stood at 3.9 percent in April and eased to 3.8 percent as inflation cooled slightly. It could shift again before autumn — that is normal, and it simply means the formula is doing its job as new data arrives.

When you will know for sure

The Social Security Administration announces the official COLA in October, after September's inflation data arrives. The new amount shows up in benefit payments starting January 2027. You do not need to do anything — the raise is automatic.

If history is any guide, the announcement will make headlines for a day. The number that deserves your longer attention comes right after it: the 2027 Medicare Part B premium, which is usually announced around the same time.

Why the raise may feel smaller than it sounds

Two quiet forces shrink a COLA before it reaches your wallet. First, the CPI-W is built on the spending patterns of working households, not retirees. Older households put more of their budgets toward housing, health care, and insurance — categories that have often climbed faster than the overall index. So even an accurately calculated raise can trail your personal costs.

Second, there is the Medicare offset. Part B premiums are deducted from most Social Security checks before the money lands in your account. Researchers at Boston College's Center for Retirement Research calculated that more than a quarter of the 2026 COLA was effectively consumed by this year's premium increase alone.

Smart moves while you wait

What this means for you

A 3.8 percent raise, if it holds, is welcome — and better than this year's. But the steadier path is planning around your whole income picture rather than one annual announcement. Our team sees this often: retirees who know their baseline, their income gap, and their net-of-Medicare deposit handle every COLA season calmly, whatever October brings.
