When does the 2027 COLA start?

With January 2027 payments for Social Security benefits. SSI payments increase on December 31, 2026, because January 1 is a federal holiday. Your COLA notice, with your exact new amount, is posted online in late November and mailed in December.

How much will my check increase?

By 3.6% of your current benefit. A $1,500 check gains $54.00 a month; the average retired worker check of $2,088 gains about $75 a month, roughly $902 a year. Deductions such as the Medicare Part B premium come out of the same check, so your net increase can be smaller.

Do I need to do anything to get the raise?

No. The COLA is automatic for everyone receiving benefits. There is no application and no fee. Anyone who calls or messages asking for a fee, gift cards, or your Social Security number to process your raise is running a scam.

Social Security COLA 2027: What the 3.6% Raise Adds to Your Check

On October 14, the Social Security Administration made it official: benefits rise 3.6% in 2027. Here is what that percentage is worth in actual dollars, when it lands, and the two deductions that quietly shrink it.

What happened

On Wednesday, October 14, 2026, the Social Security Administration announced a 3.6 percent cost-of-living adjustment (COLA) for 2027. The increase covers retirement, survivors, and disability benefits, plus Supplemental Security Income (SSI). Nearly 72 million people receive Social Security benefits and about 7.3 million receive SSI, so counting both programs, roughly 76 million Americans get this raise.

Timing matters more than the headline for most households. Social Security beneficiaries see the higher amount in their January 2027 payments. SSI recipients see it a day early, on December 31, 2026, because January 1 is a federal holiday.

For scale: this year's COLA, for 2026, was 2.8%. The 3.6% raise for 2027 is a clear step up, the largest since the 8.7% increase that took effect in 2023, and the sixth straight year with a raise of at least 2.5%. You do not need to apply for it. The increase is automatic, and the SSA posts your exact new amount in your my Social Security Message Center in late November. Paper notices follow by mail in December. If you want the online notice, create your account and choose paperless notices by November 18.

Why the number is 3.6%

Federal law sets the COLA by formula, not by a vote in Congress. The SSA compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published by the Bureau of Labor Statistics, for July, August, and September against the same three months a year earlier. Prices rose enough over that window to produce 3.6%, rounded to the nearest tenth of a percent.

That formula explains what a COLA is really for: protecting purchasing power, not adding to it. Broad consumer prices were up 3.7% in the year through September, so a 3.6% raise roughly keeps a typical check even with inflation. Whether it feels like enough depends on your own spending. If your budget leans toward categories rising faster than average, such as insurance, electricity, or medical care, your personal inflation rate can run ahead of the COLA and the raise can feel smaller than the headline.

What it means in dollars

The math: your new check is your current check times 1.036. Your monthly raise is your current check times 0.036. Three examples, worked in full:

A $1,500 check. The raise is $1,500 x 0.036 = $54.00 a month. The new check is $1,554, and over a full year the increase adds $648.

The average retiree. The average retired worker benefit is $2,088 a month (August 2026). The raise is $2,088 x 0.036 = $75.17, which the SSA rounds to the headline figure of $75 a month. The new check is $2,163.17, and the yearly gain is about $902.

A two-check household. Say a couple receives $1,900 and $1,500, for $3,400 combined. The raise is $3,400 x 0.036 = $122.40 a month, the new combined income is $3,522.40, and the yearly gain is $1,468.80.

Two lessons hide in those examples. First, a percentage raise pays the most to the biggest checks, so the dollar gap between high and low benefits widens a little every year even though everyone gets the same percentage. Second, the yearly figures are the ones worth budgeting with: $648, $902, or $1,469 is real money against property taxes, a car repair, or a few months of a utility bill, even when the monthly figure looks modest.

The two things that shrink the raise

Medicare Part B. For most beneficiaries, the Part B premium comes straight out of the Social Security check. The standard premium for 2026 is $202.90 a month. The 2027 premium has not been announced yet; it is expected in late November, and it will be printed on your COLA notice right next to your new benefit amount. If the premium rises, it eats part of the raise before you ever see it. On the average $2,088 check, the gross raise is $75.17; if the premium rose by $10 (a made-up figure, not a forecast), the net raise would be about $65. A federal hold-harmless rule protects most long-term beneficiaries from ending up with a smaller check when premiums jump, but it does not promise that your full raise survives.

Taxes. A bigger check can also mean a slightly bigger tax bill. Depending on your combined income from all sources, up to 85% of your Social Security benefit can be taxable at the federal level. For retirees in lower brackets the effect of a 3.6% raise is small, but if you sit near a threshold, the increase can push a little more of your benefit into taxable territory. It is a second-order effect, worth a glance, not a worry.

Run your own numbers

The COLA multiplies the benefit you already have. It does not change the benefit you will claim, and for anyone who has not claimed yet, the bigger levers are still your earnings record and your claiming age, which can move a check by far more than 3.6%. Our Social Security benefits estimator shows how your monthly benefit changes with the age you claim. Then put that benefit next to your savings in our retirement savings planner, which tests the combined plan against the 4% rule. Run both with your real numbers before the January check arrives, so the raise lands inside a plan instead of disappearing into general spending.

Key takeaways

The raise: 3.6% for 2027, announced October 14, up from 2.8% for 2026 and the largest since 2023. The dollars: $54 a month on a $1,500 check, about $75 on the average $2,088 check, $122.40 on a $3,400 two-check household. The timing: January 2027 for Social Security, December 31, 2026 for SSI, with exact amounts posted online in late November. The catch: the 2027 Medicare Part B premium, announced in late November, comes out of the same check, and taxes can trim a little more. The move: no action is needed to get the raise, but five minutes with the estimator and planner turns it from a headline into a number you have actually planned around.
