Social Security will announce the 2027 cost of living adjustment on October 14. That's the date third-quarter inflation data becomes final, and it's the single most consequential date of the year for a retiree's monthly income.
The percentage itself gets most of the attention, but October 14 also sets the new earnings limit for people who work while claiming early, plus the maximum benefit and the wage cap. Here's what actually happens that day, and what to line up before it arrives.
Decision
What's your situation right now?
The announcement affects people differently depending on whether you're still working.
What Actually Gets Decided on October 14
Social Security calculates the COLA from the Consumer Price Index for Urban Wage Earners and Clerical Workers, using the average from July, August, and September. The Bureau of Labor Statistics releases the September figure in mid-October, and this year that release lands on October 14, so the agency can't finalize a COLA before then.
The same announcement sets three other numbers for 2027: the earnings limit for people who claim before full retirement age and keep working, the maximum possible monthly benefit, and the wage cap, the highest amount of income subject to Social Security payroll tax.
Why the Announced Number Isn't Your Final Raise
A COLA increases your gross benefit, but most retirees have Medicare Part B premiums deducted directly from that check, and the 2027 Part B premium isn't announced until November, weeks after the COLA. That gap is why a raise on paper can shrink by the time it reaches your account.
In 2026, the 2.8% COLA lagged actual inflation, and rising Part B premiums took another bite out of it. There's no way to know the 2027 outcome in October, but waiting for both numbers before you adjust a budget keeps you from planning around a figure that's still incomplete.
Whichever situation fits you, it helps to write your questions down before you call, since Social Security's phone lines get busier once the announcement hits the news.

What to Do in the Six Weeks Before October 14
You can't know the exact numbers yet, but you can make sure a raise actually reaches you without a delay. Most COLA problems aren't about the percentage. They're about outdated bank information or an online account nobody checked all year.
Start with your online access, since that's also where Social Security posts your personalized COLA notice every December, instead of always mailing a paper copy.
Mark the Full Calendar, Not Just One Date
October 14 starts a short run of dates that matter together. Medicare's open enrollment period runs October 15 through December 7, right after the COLA announcement and before the Part B premium is final for most of that window.
Your personalized COLA notice typically arrives in early December, close to when open enrollment ends, so treat that notice as the last input before you finalize any coverage change, not an afterthought.

Common questions
When will Social Security announce the 2027 COLA?
October 14. Social Security calculates the COLA from the average Consumer Price Index for Urban Wage Earners and Clerical Workers across July, August, and September, and the Bureau of Labor Statistics releases the September figure in mid-October. The agency can't finalize a number until that data is out, which is why this year's announcement lands on October 14.
Why isn't the COLA percentage my actual raise?
Most retirees have their Medicare Part B premium deducted directly from their Social Security check, and the 2027 Part B premium isn't announced until November, weeks after the COLA. A raise that looks solid in October can shrink once the premium is set. Wait for both numbers before recalculating your monthly budget.
What if I'm still working while collecting Social Security?
The October 14 announcement also resets the earnings limit for people who claim before full retirement age and keep working. Ask for the new limit once it's out and compare it to your expected 2027 earnings. If you do go over it and some benefits get withheld, that money usually isn't lost. Social Security generally credits it back once you reach full retirement age.
How will I find out my new payment amount?
Social Security typically mails a personalized COLA notice in early December, or posts it to your online message center if you opted into electronic notices. Log into your my Social Security account now to confirm your password works and your direct deposit information is current, so nothing delays that notice from reaching you.
