The 2027 cost-of-living adjustment has not been announced yet. The Social Security Administration expects to determine it in October 2026, and until then no figure is official.
That matters because forecasts circulate all autumn, some of them confident and some of them attached to services that want your details. This guide covers when the real number arrives, how it is calculated, and when your payment actually changes.
For reference, the most recent determination was a 2.8% COLA for 2026, set on 24 October 2025.
Key takeaway
The 2027 COLA is expected to be announced in October 2026 by the Social Security Administration. It is based on the Consumer Price Index, and increased payments have historically taken effect with January payments. Until the announcement, every circulating figure is an estimate, not the adjustment.

When the figure becomes official
The Social Security Administration determines the annual COLA in the autumn and publishes it on its own site. The 2.8% adjustment for 2026 was determined on 24 October 2025, and the administration states that the next announcement is expected in October 2026.
No commercial site, newsletter or app receives the number earlier. Anything published before the announcement is a projection based on inflation data, however precisely it is worded.

Social Security's general benefit increases are based on increases in the cost of living, as measured by the Consumer Price Index. Because the index reading that completes the calculation is not published until autumn, the figure cannot be known with certainty before then.
This is why estimates published in spring and summer routinely move. They are extrapolating from partial data.
When your payment actually changes
For the 2026 adjustment, the Social Security Administration stated that beneficiaries and Supplemental Security Income recipients would receive the 2.8% COLA with payments payable in January 2026.
Expect the same pattern rather than assuming it: the announcement lands in October, and the increase appears in the following January's payments. Your own payment date within January still depends on the ordinary payment schedule.
The Social Security Administration also sends a notice showing your new benefit amount. Check that against your own arithmetic, because a Medicare Part B premium change is deducted from many benefits and can offset part of the increase.
The other figures announced at the same time
The COLA announcement carries several other numbers that matter to people still working. For 2026 these were:
| Figure | 2026 amount |
|---|---|
| Maximum taxable earnings | $184,500, up from $176,100 in 2025 |
| Earnings test, before full retirement age | $24,480 a year ($2,040 a month), $1 withheld per $2 above |
| Earnings test, year you reach full retirement age | $65,160 a year ($5,430 a month), $1 withheld per $3 above |
| At and after full retirement age | No earnings limit |
The 2027 equivalents will be published alongside the 2027 COLA. If you are working while claiming, those are the numbers to watch, not only the percentage.
Protecting yourself before the announcement
- Get the figure from the Social Security Administration's own site, not from a forwarded message.
- Ignore anyone offering to tell you your new amount early in exchange for personal details.
- The Social Security Administration does not require a payment to apply a COLA. It is automatic.
- Set up or check your personal my Social Security account before the announcement, so you can read your own notice directly.
COLA season is a reliable annual peak for benefit-related impersonation. The adjustment requires nothing from you at all.

What is the 2027 COLA?
It has not been announced. The Social Security Administration expects to determine it in October 2026.
When will my payment increase?
For 2026 the increase was payable in January. Expect the same pattern for 2027, confirmed by the announcement and your own notice.
Why do estimates keep changing?
Because the calculation depends on Consumer Price Index data that is not complete until autumn. Every earlier figure is an extrapolation.
Do I need to apply for the COLA?
No. It is applied automatically, and nobody legitimate will ask you to pay or to submit information to receive it.
Will my whole increase reach my bank account?
Not necessarily. Medicare Part B premiums are deducted from many benefits, so a premium increase can offset part of the adjustment. Your notice will show the net figure.
Summary
October 2026 is when the 2027 figure becomes real. Everything before that is an estimate, and the estimates move.
Read it on the Social Security Administration's own site, check your notice for the Medicare deduction, and treat any early offer to reveal your new amount as a warning sign.
