When Will the 2027 Social Security COLA Arrive?
Last verified 2026-08-05
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.
Last verified: August 5, 2026. This page should be updated after the official Social Security COLA announcement scheduled for October 14, 2026.
The 2027 Social Security COLA does not “arrive” on one date. The official percentage is scheduled to be announced on October 14, 2026, after the September inflation report. The personal dollar amount should show up in COLA notices in December 2026. The higher benefit is then paid with January 2027 Social Security payments on the regular birthday-based schedule, with SSI paid on December 31, 2026.[1]
That date chain matters more than any projected average. A headline saying seniors may get “about $75 more” can be useful for rough household planning, but it is not a promise about your own January deposit. Your actual amount depends on your benefit before the COLA and, for many retirees, deductions such as Medicare Part B premiums.
The dates to mark: announcement, notice, and January payment
If you are helping a parent or spouse track this, it helps to separate the dates by job: one date tells the public the official COLA percentage, one period tells beneficiaries their own new amount, and one January payment date is when the adjusted money is due to land.
| Date or period | What happens | What to do |
|---|---|---|
| October 14, 2026 | Social Security is scheduled to announce the official 2027 COLA after the September CPI report. | Use this as the date the projection becomes an official percentage, not as a deposit date. |
| Around November 2026 | Medicare Part B premiums are expected to be finalized around this period. | Wait for this before assuming the net increase in a Social Security deposit. |
| December 2026 | SSA sends COLA notices with the new benefit amount. | Read the notice or check the my Social Security Message Center if paperless. |
| December 31, 2026 | SSI recipients are scheduled to receive the January 2027 SSI payment. | Check the SSI deposit separately from Social Security retirement or disability payments. |
| January 3, 2027 | Payment date for people who began receiving Social Security before May 1998. | Use this date only if this older-payment-rule group applies. |
| January 13, 2027 | Payment date for birthdays on the 1st through 10th of the month. | Compare the deposit with the COLA notice. |
| January 20, 2027 | Payment date for birthdays on the 11th through 20th of the month. | Compare the deposit with the COLA notice. |
| January 27, 2027 | Payment date for birthdays on the 21st through 31st of the month. | Compare the deposit with the COLA notice. |
The October date answers “What is the official COLA?” The December notice answers “What is my new benefit amount?” The January payment date answers “When should I see it in the bank?” Mixing those up is how a perfectly normal benefits update turns into unnecessary worry.
For a deeper explanation of the birthday rule itself, use the Social Security payment schedule. The practical point for this COLA is simpler: most retirees will not see the increase on January 1. They should look to their usual January payment date.
Where your personal 2027 COLA amount appears
The document to look for is the annual COLA notice. Social Security describes the current notice as a simplified, one-page notice that tells beneficiaries their new benefit amount. People who have a my Social Security account and have opted out of mailed notices can view the notice in the Message Center.[2]
When the notice arrives, do not try to back into the number from a news article. Put the notice next to the January deposit and check three things:
- The new monthly benefit amount shown on the COLA notice.
- Any Medicare deduction or other withholding that changes the amount deposited.
- The January payment date that applies to the beneficiary’s payment group.
This is also the safest way for an adult child to help without guessing. Ask for the December COLA notice, or help the beneficiary sign in to their own my Social Security account and open the Message Center if they use paperless notices. If you are comparing the notice to a bank deposit, compare the January 2027 deposit, not a December 2026 Social Security payment.
If the gross increase on the notice looks larger than the change in the bank deposit, Medicare Part B is one of the first places to check. The Part B premium is not the COLA, but it can affect the net amount that arrives. For that issue, see how Medicare Part B can affect the 2027 net Social Security benefit.
What the 2027 COLA projections say — and what they do not say
As of August 5, 2026, the 2027 COLA is still a projection. AARP reported a July 14, 2026 estimate of 3.6%, equal to about $75 per month when applied to a roughly $2,084 average retired-worker benefit.[3] The Senior Citizens League has estimated 3.8% using a $1,937.53 baseline.[4] CNBC Select cited Mary Johnson’s 3.7% estimate and described the projected monthly increase range as roughly $73 to $79, depending on the baseline used.[1]
Those figures are not interchangeable. One estimate may use an average retired-worker benefit; another may use a broader all-beneficiaries baseline; another may cite a different average month. If a person’s current benefit is higher or lower than the average used in the article, the dollar increase will be higher or lower too. If Medicare deductions change, the deposited increase may differ again.
For historical context, the 2026 COLA was 2.8%, and Social Security said it raised the average retired-worker benefit from about $2,015 to about $2,071.[5] That helps show the scale of a recent COLA, but it is not a shortcut for calculating a particular person’s 2027 amount.
If you want the inflation formula behind the October number, use the CPI-W COLA explanation. If you are tracking only the latest estimate range before October, use the current 2027 Social Security COLA forecast. For the average-versus-personal issue, see why your 2027 Social Security increase may differ from the average.
A simple verification checklist
- Mark October 14, 2026 as the official COLA announcement date.
- Wait for the December 2026 COLA notice before treating any dollar amount as personal.
- If paperless, check the my Social Security Message Center for the notice.
- Find the January 2027 payment date that applies: January 3 for those who began benefits before May 1998, January 13 for birthdays 1–10, January 20 for birthdays 11–20, or January 27 for birthdays 21–31.
- For SSI, check the December 31, 2026 payment date for the January 2027 payment.
- Compare the COLA notice with the actual January deposit, especially if Medicare deductions apply.
The official 2027 Social Security COLA is not known until October 14, 2026. Until then, the published 3.6%, 3.7%, and 3.8% figures are projections. The exact dollar amount for one retiree belongs in that retiree’s COLA notice or my Social Security account, not in an average printed in a headline.
