When Will the 2027 Social Security COLA Be Announced?
Last verified 2026-08-01
This is not financial or legal advice. Medicare/Medicaid and benefits rules vary by state and change over time — verify current rules with your state Medicaid office or Area Agency on Aging.
The 2027 Social Security COLA is most likely to be announced on October 14, 2026, the day September inflation data is expected to be released at 8:30 a.m. ET, with the Social Security Administration expected to confirm the final rate shortly afterward. For seniors and caregivers trying to mark a calendar, that is the working date to watch — but it is still an expected date, not the official benefit increase yet.
SSA’s own cost-of-living page currently says the next COLA will be announced in October 2026, without naming a specific day.[1] AARP and cleveland.com identify October 14, 2026, because that is when the Bureau of Labor Statistics September CPI release is expected, and that September number completes the inflation period used for the COLA calculation.[2][3] The caution matters: the 2025 COLA announcement was delayed from October 15 to October 24 during a government shutdown, so October 14 should be treated as the best current expectation, not a guarantee.[2]

Why the announcement centers on October 14
The COLA is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. SSA bases the COLA on the year-over-year change in the average CPI-W for the third quarter — July, August, and September — and the increase becomes effective with January payments.[4]
That is why September matters more than any single summer estimate. July and August can point the calculation in a direction, but September closes the quarter. Once that release is out, the final COLA can be calculated and SSA can announce the official percentage.
Until SSA posts the number, no percentage is official. A projected 3.6%, 3.7%, or 3.8% may be useful for a rough grocery-and-premium budget, but it is not the amount that will appear in a benefit notice.
The full 2027 COLA timeline to put on the calendar
| When | What happens | What to do with it |
|---|---|---|
| August–September 2026 | The third-quarter CPI-W period is still being completed. | Use estimates only for rough planning; do not treat any forecast as your raise. |
| October 14, 2026, expected | September CPI data is expected at 8:30 a.m. ET, and SSA is expected to confirm the 2027 COLA afterward.[2][3] | Watch SSA’s official announcement before updating a household budget. |
| Late November or early December 2026 | COLA notices are expected to appear online through the my Social Security Message Center.[5] | Check your online account if you use one, especially before waiting on mail. |
| December 2026 | Mailed COLA notices continue through December.[5] | Save the notice with tax and benefit papers; it shows your new monthly amount. |
| December 31, 2026 | SSI recipients are expected to receive the January 2027 federal SSI payment on this date because of the New Year holiday timing.[4] | If you receive SSI, this may be the first payment affected by the 2027 COLA. |
| January 2027 | Social Security retirement, disability, and survivor benefits reflect the COLA with January payments.[4] | Use your own SSA payment schedule rather than an unofficial copied date list. |

The online notice is often the first place many people will see their own new dollar amount. SSA says COLA notices are available online in the Message Center in late November or early December, and mailed notices go out throughout December.[5] That timing is useful if an adult child is helping a parent review rent, prescription costs, supplemental insurance, or a new Medicare premium.
The January check date is personal. Social Security payments do not all arrive on the same day, and exact January 2027 dates should be checked against SSA’s official payment schedule before anyone builds a cash-flow plan around them. That is especially important when a regular payment date falls near a weekend or federal holiday.
Where the current COLA estimates fit
As of mid-July 2026, public estimates were clustered in the high-3% range: The Senior Citizens League held its 2027 COLA projection at 3.8%, AARP cited an estimated 3.6%, and analyst Mary Johnson projected 3.7%.[6][2][7] Those figures are budgeting context only. They will move as third-quarter CPI-W data comes in, and none of them replaces the SSA announcement.
For a deeper look at how the estimate may feel after real expenses, see the site’s 2027 Social Security COLA prediction, the net benefit after Medicare discussion, and the COLA versus rising costs explainer. This page is only about the announcement and payment timeline.
What seniors can safely plan before the official number
- Circle October 14, 2026, as the expected announcement date, while remembering SSA officially says only October 2026.
- Wait for SSA’s official percentage before changing automatic transfers, rent plans, or recurring bill assumptions.
- Check the my Social Security Message Center in late November or early December if you use an online account.
- Watch the mail through December if you rely on paper notices.
- Expect the larger Social Security benefit to show up with your January 2027 payment, according to your regular SSA payment schedule.
The exact COLA percentage is still unknown, but the sequence is already clear enough for practical planning: October announcement, late-November or early-December online notice, December mailed notice, and the first larger benefit payment in January 2027.
