Social Security 2027 COLA Notices: More than 75 million Social Security and Supplemental Security Income recipients are about to find out exactly how much bigger their checks will be next year, and the timeline for that answer is now locked in. The Social Security Administration will announce the official 2027 cost-of-living adjustment on October 14, 2026, immediately after the Bureau of Labor Statistics releases the September inflation report that completes the calculation. Based on the July and August data already in hand, independent forecasters including AARP, The Senior Citizens League, and the Committee for a Responsible Federal Budget currently place the 2027 COLA somewhere between 3.4% and 3.6%, which would mark the largest annual increase since 2023 and a clear jump from the 2.8% adjustment that took effect this year.
But the percentage announced in October is only half the story. Your actual COLA notice, the personalized letter that tells you your exact new dollar amount, your Medicare Part B deduction, and your net deposit, does not go out until December, and increasingly it shows up online before it ever reaches your mailbox. Below, we walk through exactly when your 2027 COLA notice will arrive, what each line of it means, how to see it early through your my Social Security account, and a free calculator so you can estimate your new payment before the letter shows up. We’ll be updating this article monthly as new inflation data and official SSA figures are released.

What Is the Social Security COLA and Why It Matters for 2027
The cost-of-living adjustment is the annual increase Social Security applies to benefits so that fixed monthly checks keep pace with inflation. Every year, the Social Security Administration compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, across the third quarter (July, August, and September) of the current year against the same three months of the previous year. The percentage difference becomes the official COLA. Because the calculation depends entirely on the September CPI-W report, the exact 2027 COLA cannot be finalized until that data is released, which is why the Social Security 2027 COLA notice process always follows the same two-step pattern: an October percentage announcement, followed by a December mailing of individualized dollar notices.
Over the past decade, the average COLA has run around 3.1%, so a 2027 figure of 3.4% to 3.6% would land slightly above the historical norm. It would also be the biggest increase beneficiaries have seen since the 8.7% COLA in 2023, driven at the time by pandemic-era inflation. This year’s projected increase is far more modest by comparison but still meaningfully larger than the 2.8% and 2.5% adjustments retirees received in 2026 and 2025.

Social Security 2027 COLA Amount: What the Projections Show
As of this writing, the 2027 COLA has not yet been officially confirmed, and any number you see before October 14, 2026 is an estimate based on partial-year inflation data. That said, the range among major forecasters has narrowed considerably heading into the final report:
- AARP’s most recent projection: 3.6%
- The Senior Citizens League’s most recent projection: 3.5%
- The Committee for a Responsible Federal Budget’s projection: 3.4%
- Independent analyst Mary Johnson’s revised projection: approximately 3.4% to 3.7%
If the final 2027 COLA lands at 3.5%, the average retired worker benefit would rise from roughly $2,085 to about $2,159 per month, an increase of approximately $73. A COLA closer to 3.6% would push the average benefit closer to $2,161, an increase of about $75 to $76. These are averages only. Your individual increase depends on your current benefit amount, since the COLA is applied as a percentage, not a flat dollar figure, meaning higher earners see a larger dollar increase even though everyone receives the same percentage bump.
Recent COLA History: How 2027 Compares
Looking at recent adjustments helps put the projected 2027 COLA in perspective. Below is how the last several years compare, based on official SSA announcements.
| Year | Official COLA | Average Retired Worker Increase |
|---|---|---|
| 2023 | 8.7% | Largest increase in over four decades, driven by pandemic-era inflation |
| 2024 | 3.2% | Roughly $59 per month |
| 2025 | 2.5% | Roughly $50 per month |
| 2026 | 2.8% | Roughly $56 per month |
| 2027 | Not yet announced (projected 3.4% to 3.6%) | Projected $73 to $76 per month |
The pattern shows inflation cooling sharply after 2023 before ticking back up heading into 2027. If the final number comes in at the high end of current projections, 2027 would be the largest COLA beneficiaries have seen since that 2023 spike, even though it remains far smaller in absolute terms.
When Will the 2027 COLA Be Officially Announced?
The Social Security Administration will announce the official 2027 COLA percentage on October 14, 2026, the same day the Bureau of Labor Statistics publishes the September Consumer Price Index report. This is not a guess or a placeholder date. The SSA’s COLA determination is required by law to use third-quarter CPI-W data, and September is always the final month needed, which is why the announcement consistently falls in mid-October each year. Once the percentage is confirmed, the SSA calculates individual benefit amounts and begins preparing the personalized notices that follow in the weeks after.
When Will Your Social Security COLA Notice Arrive?
This is the part of the process that generates the most search traffic every year, because the October announcement only tells you the percentage, not your actual new benefit amount in dollars. Based on the SSA’s consistent practice in recent years, here is what to expect for the Social Security 2027 COLA notice:
- Online notices: Beneficiaries with a my Social Security account will typically be able to view their personalized COLA notice in the account’s Message Center starting in late November, ahead of the mailed version.
- Mailed notices: Paper COLA notices are sent out on a rolling basis throughout the month of December to retirement, survivors, and disability beneficiaries, SSI recipients, and representative payees.
- Opt-out deadline: In previous years, beneficiaries who wanted to receive their notice online only, rather than by mail, needed to log in to their my Social Security account and switch their Message Center preference to electronic notices by a cutoff date in mid to late November. Check ssa.gov/myaccount closer to the date for this year’s exact cutoff, since the SSA typically confirms it alongside the October COLA announcement.
- Medicare premium timing: For beneficiaries enrolled in Medicare, the 2027 Part B premium amount is generally posted to the my Social Security Message Center starting in late November as well, before the full COLA notice goes out.
If you have not received your notice by the end of December, the fastest way to confirm your new amount is to log in to your my Social Security account rather than waiting on the mail, since online notices are consistently available first.
What Your 2027 COLA Notice Will Show
In recent years, the SSA redesigned its COLA letter into a simplified, one-page format written in plain, personalized language rather than dense government boilerplate. Your Social Security 2027 COLA notice should include:
- Your new gross monthly benefit amount before any deductions
- The effective date of the increase, which for most beneficiaries is the January 2027 payment
- Any Medicare Part B premium amount being deducted directly from your check
- Any Medicare Part D or supplemental deduction on file
- Your final net deposit amount after all deductions
- The exact date your first increased payment will be issued, based on your birth date or payment schedule
Because Medicare Part B premiums are typically deducted straight from Social Security checks, your notice will show both the gross increase from the COLA and the net increase after the higher premium is subtracted, which is often noticeably smaller than the headline COLA percentage suggests.
How to Apply for or Access Your COLA Notice
There is no application required to receive the COLA. It is applied automatically to every eligible beneficiary’s record. However, accessing your notice as early and securely as possible does require a few simple steps:
- Create or log in to your personal my Social Security account at ssa.gov/myaccount if you have not already done so.
- Go to your Message Center preferences and choose to receive notices electronically instead of, or in addition to, paper mail.
- Set up email or text alerts so you are notified the moment a new message, including your COLA notice, is posted to your account.
- Check the Message Center starting in late November for Medicare premium information and again for your full COLA notice.
- If you do not use online services, simply wait for the mailed notice, which arrives on a staggered schedule throughout December, and contact the SSA only if you have not received anything by early January.
Social Security 2027 Payment Schedule and Processing Time
The 2027 COLA affects two groups on two different timelines. Supplemental Security Income recipients see their increased payment on December 31, 2026, because SSI payments are issued on the last business day of the prior month when the first of the month falls on a weekend or holiday. Social Security retirement, survivors, and disability beneficiaries see the new amount starting with their January 2027 payment, which is issued according to the standard schedule based on the beneficiary’s date of birth or, for those who began receiving benefits before May 1997, a fixed early-month schedule.
Processing itself is automatic. You do not need to file anything or contact the SSA to receive your increase. The only reason a beneficiary would experience a delay is a separate issue unrelated to the COLA, such as a change of address, a representative payee update, or a benefit verification hold, in which case contacting the SSA directly is the fastest path to resolution.
How Medicare Premiums Could Offset Your 2027 COLA
For the roughly 70 percent of Medicare beneficiaries who have their Part B premium deducted directly from their Social Security check, the COLA increase and the Medicare premium increase arrive together, and the net effect on your deposit is what actually matters for your budget. The 2026 Medicare Trustees Report projects the standard Part B premium will rise to approximately $209.50 in 2027, up from $202.90 in 2026, an increase of about $6.60 per month. That is a smaller jump than the nearly 10 percent premium spike beneficiaries absorbed between 2025 and 2026, so most retirees should keep a larger share of their 2027 COLA than they did the prior year. The Part B deductible is also projected to rise slightly, to roughly $292 from $283. A hold-harmless provision in the Social Security Act generally prevents your net check from shrinking even if a Medicare premium increase exceeds your COLA, though this protection applies mainly to premium increases, not to other deductions.

Other 2027 Changes That Will Appear Alongside Your COLA
Your COLA notice focuses on your personal benefit amount, but several related figures change at the same time and are worth knowing if you are still working or claiming benefits early. The Social Security taxable wage base, the maximum amount of earnings subject to Social Security payroll tax, is projected by the SSA Board of Trustees to rise to approximately $190,200 in 2027, up from $184,500 in 2026. The retirement earnings test limits, which reduce benefits for beneficiaries who claim early and continue working, are also adjusted each year in line with wage growth and will be confirmed alongside the October COLA announcement.

The official 2027 COLA will be announced on October 14, 2026, right after the Bureau of Labor Statistics releases the September Consumer Price Index report.
How much will the Social Security COLA increase in 2027?
As of now, the 2027 COLA has not been finalized. Leading forecasters project a range between 3.4% and 3.6%, which would be the largest increase since 2023.
When will I get my Social Security COLA notice for 2027?
Notices are typically available online through the my Social Security Message Center starting in late November, with paper notices mailed on a staggered schedule throughout December 2026.
What does the Social Security COLA notice show?
It shows your new gross monthly benefit, any Medicare premium or other deductions, your final net payment amount, and the effective date of your first increased check.
Do I need to apply to get the Social Security COLA increase?
No. The increase is applied automatically to every eligible beneficiary. There is no separate application or form required.
When does the 2027 COLA actually start affecting my payments?
Social Security retirement, survivors, and disability beneficiaries see the increase starting with the January 2027 payment. SSI recipients see it starting December 31, 2026.
Will my Medicare premium wipe out my 2027 COLA increase?
It is unlikely to wipe it out entirely this year. The Medicare Part B premium is projected to rise by about $6.60 per month in 2027, a much smaller increase than the near ten percent jump seen in 2026, so most beneficiaries should keep a meaningful share of their COLA.
How can I see my COLA notice before it arrives in the mail?
Log in to or create a my Social Security account at ssa.gov/myaccount and switch your Message Center preferences to receive notices online, which typically post several weeks before the paper version arrives.
What was the Social Security COLA for 2026?
The 2026 COLA was 2.8%, which raised the average retired worker’s benefit by about $56 per month.
Is a 3.5% COLA good or bad for retirees?
A COLA above the ten-year average of roughly 3.1% generally reflects continued elevated inflation, meaning the dollar increase helps offset rising costs but does not necessarily improve a retiree’s overall purchasing power, since expenses like healthcare often rise faster than the CPI-W measure used to calculate the COLA.
Conclusion
The Social Security 2027 COLA notice season follows a predictable two-step calendar every year, and 2027 is no exception. Expect the official percentage, currently projected between 3.4% and 3.6%, on October 14, 2026, followed by your personalized dollar notice online in late November and by mail throughout December. The fastest and most secure way to see your exact new benefit amount is through your my Social Security account rather than waiting on the postal mail. Use the calculator above once the official percentage is confirmed to estimate your new monthly deposit, and check the official SSA resources listed here for the most current figures as they are finalized. We will keep updating this page every month as the September inflation data, the official COLA announcement, and the finalized Medicare premiums are released.
