The 2027 COLA will be announced in October 2026, and the exact amount depends on inflation data collected through September
The Cost of Living Adjustment (COLA) for 2027 has not yet been set. Social Security announces the COLA each October for the following year, based on how much prices rose from July through September. The 2027 COLA will be announced in October 2026.
If you receive Social Security retirement, disability, or survivor benefits, your monthly payment will increase by whatever percentage the COLA sets. The increase takes effect in January. You do not need to do anything — Social Security applies it automatically.
Past COLA amounts show the range of what can happen. The 2024 COLA was 3.2 percent. The 2025 COLA is 2.5 percent. In 2022, during high inflation, the COLA was 8.7 percent. In years of very low inflation, the COLA has been as low as 0.3 percent or even zero. The 2027 COLA will fall somewhere in that range depending on what inflation looks like in the summer and early fall of 2026.
Key Takeaways
- The 2027 COLA will be announced in October 2026 and will take effect on your January 2027 benefit payment.
- The COLA is calculated from inflation data collected July through September of the year before, so it reflects actual price changes, not predictions.
- Every Social Security beneficiary receives the same COLA percentage — there is no individual variation based on age, benefit amount, or location.
- You cannot plan your 2027 budget around a specific COLA amount until October 2026, when Social Security makes the official announcement.
How Social Security calculates the COLA each year
Social Security uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published by the Bureau of Labor Statistics. This index tracks the cost of food, housing, transportation, medical care, and other goods and services that people buy.
The agency compares the average CPI-W for July, August, and September of one year to the average for the same three months of the previous year. If prices went up, that percentage increase becomes the COLA. If prices stayed flat or fell, the COLA is zero — benefits do not decrease.
This calculation happens automatically. Social Security does not vote on the COLA or adjust it for policy reasons. The number comes directly from the inflation data.
When you will see the 2027 COLA in your payment
If you receive benefits by direct deposit, the increase will appear in your bank account on the third Wednesday of January 2027. If you receive a check, it will arrive in early January with the new amount.
Supplemental Security Income (SSI) recipients also receive a COLA, and it takes effect on the same schedule — January 2027.
Medicare Part B premiums, which are deducted from many Social Security checks, may also change in 2027. The Part B premium is set separately and announced in the fall, so your net increase (the COLA minus any premium increase) may be smaller than the COLA percentage alone.
Why the COLA matters for your long-term benefits
The COLA compounds over time. A 2.5 percent increase in 2027 becomes part of your new base benefit amount. The 2028 COLA, whenever it is set, will be calculated on that higher amount. Over decades of retirement, COLA increases significantly affect your total lifetime benefits.
For someone receiving $1,800 per month, a 2.5 percent COLA adds $45 per month. That $45 becomes permanent — it does not reset each year. Future COLAs build on top of it.
What inflation trends might mean for 2027
No one can predict the 2027 COLA with certainty. It depends entirely on what happens to prices between July and September 2026. If inflation remains low and stable, the COLA could be modest — around 2 to 3 percent. If inflation rises sharply, the COLA could be higher. If prices fall, the COLA would be zero.
Economists and policy analysts sometimes publish estimates in the months before the announcement, but these are educated guesses, not guarantees. The actual number will come from the inflation data in October 2026.
How to stay informed about the 2027 COLA announcement
Social Security publishes the COLA announcement on its official website, ssa.gov, in early October each year. You can also call Social Security at 1-800-772-1213 to ask about the 2027 COLA once it is announced.
Your Social Security statement, which you can view online at ssa.gov or request by mail, shows your current benefit amount but will not show the 2027 amount until after the COLA is announced.
Some news outlets and financial websites publish the announcement on the same day, so checking a major news source in early October 2026 will also give you the official figure.
Frequently Asked Questions
Can I request a higher COLA or appeal the 2027 amount?
No. The COLA is set by a formula based on inflation data. Social Security does not have discretion to adjust it for individual circumstances or to change the overall percentage. The amount is the same for all beneficiaries.
Will the 2027 COLA affect my Medicare premiums?
The COLA itself does not directly set Medicare premiums, but the timing is related. Medicare Part B premiums are announced in the fall and take effect in January alongside the COLA. Your net benefit increase depends on both numbers. Some years the premium increase is small, and you keep most of the COLA. Other years the premium rises more, reducing your net gain.
Does the COLA apply if I have not started benefits yet?
No. The COLA only affects people already receiving benefits. If you claim Social Security in 2027 or later, your initial benefit amount will reflect all the COLAs that occurred before you claimed, but you do not receive a separate 2027 COLA payment on top of that.
What if I am receiving both Social Security and SSI?
Both programs receive the same COLA percentage, and both increase in January 2027. However, SSI has income and resource limits, so a COLA increase might affect your SSI amount differently than it affects your Social Security amount. Contact Social Security if you receive both to understand how the 2027 COLA will change your total payment.
