Social Security 2027 COLA Report: The Social Security 2027 COLA is now one inflation report away from being final, and that report lands on October 14. The Bureau of Labor Statistics will publish the September Consumer Price Index at 8:30 a.m. Eastern, and the Social Security Administration is expected to announce the official cost of living adjustment the same day. July and August are already in the books. The CPI-W, the index that drives the raise, rose 3.4 percent over the year in July and 3.5 percent in August. That puts the 2027 COLA on track to beat the 2.8 percent raise retirees received for 2026. The Senior Citizens League has issued its final forecast of 3.5 percent, AARP sits at 3.6 percent, and independent analyst Mary Johnson is near 3.4 percent. We’ll be updating this article monthly.
Why does one report matter so much? Because the COLA is not based on any single month. It uses the average CPI-W for July, August and September, compared with the same three months a year earlier. Two of the three numbers are locked. The third can still nudge the final percentage up or down by a tenth of a point, and every tenth is worth about $2 a month to the average retiree. Energy prices are the wild card, with diesel hitting a record above $6 a gallon in September. For more than 70 million Americans who get retirement, disability or SSI payments, this single release sets the size of the January raise. Below you will find the latest forecasts, a free 2027 COLA calculator, key dates, how the raise will interact with Medicare, and the official links you need.

How the Social Security COLA Is Calculated?
The formula is simple once you see it. The Social Security Administration takes the average CPI-W for the third quarter of the current year, which means July, August and September. It compares that average with the third quarter average from the year before. The percentage gain, rounded to the nearest tenth, becomes the COLA. For the 2026 raise, the third quarter of 2025 averaged 315.664 on the CPI-W. Any average for the third quarter of 2026 will be measured against that number.
That base matters because it means the COLA is a full three month story. A quiet September will pull the average toward the lower end of forecasts. A jump in fuel and food prices will push it up. This is also why forecasters stopped moving their numbers much once August data arrived. With two of three readings known, the remaining uncertainty is small, but it is not zero.
Why the September CPI-W Report Could Change Your 2027 Raise
Think of the final report as a swing vote. If September inflation comes in close to August, the COLA should settle at 3.5 percent. If prices cool, the final number could slip to 3.4 percent. If energy costs keep climbing, 3.6 percent is realistic. Anything outside that band would take a surprise. The Senior Citizens League has said its main concern is short term shocks that could push inflation sharply higher or lower in the last month.
There is also a timing risk worth remembering. Last year’s COLA announcement was delayed because a government shutdown pushed back the September inflation report. Nothing in the current schedule points to a delay this year, but the official confirmation only counts once BLS and SSA publish. Retirees should treat every forecast as a planning number until then.

2027 COLA Predictions: What Forecasters Say Now
| Source | 2027 COLA estimate | Notes |
|---|---|---|
| The Senior Citizens League | 3.5 percent | Final forecast after August data; average check up about $67.90 |
| AARP | 3.6 percent | Would lift the average retired worker benefit by about $75 |
| Mary Johnson, independent analyst | About 3.4 percent | Earlier in the year her estimate was as high as 4.7 percent |
| MyFederalRetirement tracking | 3.5 to 3.6 percent | Applies to Social Security and CSRS |
Notice that estimates have come down over the summer. One forecaster had the COLA as high as 3.8 percent earlier, and another had 4.7 percent at one point. Cooling inflation in the summer months trimmed those numbers, and the final range has tightened around the mid 3s.

What the 2027 COLA Means for Average Social Security Checks
Two averages appear in the news, and they are not the same. The Social Security Administration reported that the average retired worker received $2,071 a month in January 2026. The Senior Citizens League uses a broader average of $1,940.08 that includes all beneficiaries. Here is how each would change.
| COLA | Retired worker raise | New retired worker average | All beneficiary raise | New all beneficiary average |
|---|---|---|---|---|
| 3.4 percent | $70.41 | $2,141.41 | $65.96 | $2,006.04 |
| 3.5 percent | $72.49 | $2,143.49 | $67.90 | $2,007.98 |
| 3.6 percent | $74.56 | $2,145.56 | $69.84 | $2,009.92 |
Different outlets report slightly different dollar amounts, such as $73.01, because they start from different averages. The percentage is what SSA announces, and your own raise equals your own benefit times that percentage.
Will Medicare Part B Take Part of the 2027 COLA?
For most people, yes, at least a little. The Part B premium comes out of the check before deposit. The 2026 premium is $202.90, and the Medicare Trustees project $209.50 for 2027, a $6.60 increase. Some private forecasters expect $216 to $219. On a 3.5 percent raise for the average retired worker, a $209.50 premium would leave about $65.89 of the $72.49 gain, while a $219 premium would leave about $56.39. The official figure will be announced in November, so do not treat the projection as final. Our companion guide on Medicare Part B and the COLA has a separate calculator for that comparison.
FERS and CSRS Retirees: Does the 2027 COLA Work the Same Way?
Not quite. CSRS retirees receive the same percentage as Social Security. FERS retirees follow a different rule set by the Office of Personnel Management. When inflation is 2 percent or less, they get the full amount. Between 2 and 3 percent, they get 2 percent. Above 3 percent, they get the inflation figure minus one point. So a 3.5 percent Social Security COLA would translate to about 2.5 percent for most eligible FERS retirees. The calculator above has a FERS setting for this.

Other 2027 Social Security Changes Announced With the COLA
The COLA is not the only number that resets in October. SSA also publishes the new maximum taxable earnings, the earnings test limits, the value of a work credit, the substantial gainful activity thresholds, and updated SSI rates. These are the 2026 figures for comparison, and 2027 amounts will be published with the announcement.
| Item | 2026 amount | 2027 amount |
|---|---|---|
| Maximum taxable earnings | $184,500 | To be announced |
| Earnings test limit (under full retirement age) | $24,480 a year | To be announced |
| Earnings test limit (year reaching full retirement age) | $65,160 a year | To be announced |
| SSI federal payment, individual | $994 a month | To be announced |
| SSI federal payment, couple | $1,491 a month | To be announced |
Is the COLA Keeping Up? The Buying Power Question
Even a 3.5 percent COLA does not settle the bigger debate. The Senior Citizens League says that compared with 2016, benefits are worth only about 86.3 cents on the dollar. Their study estimates payments would need to rise 15.7 percent, or about $295.85 a month for the average beneficiary, to recover the lost value. The group argues that older adults spend more on health care, housing and energy than the CPI-W weights suggest, which is why raises can feel smaller than the headline. Supporters of the current formula respond that CPI-W is a consistent, widely used measure and that changing it would carry trade offs for the trust funds.
How to Apply for Social Security to Get the COLA?
You do not apply for the COLA itself. It is added automatically to every benefit. But you must be receiving or approved for benefits to get it. Here is how to start a claim:
| Step | What to do |
|---|---|
| 1 | Create or log in to your my Social Security account. |
| 2 | Review your earnings record and your estimated benefit at different claiming ages. |
| 3 | Apply online for retirement, disability or spouse benefits, or call the national number to apply by phone. |
| 4 | Choose direct deposit so the raise arrives without delay. |
| 5 | Check your application status online after you submit. |
Retirement benefits can start as early as age 62, but claiming early reduces the monthly amount for life. Waiting until full retirement age or later raises it. Since COLAs are a percentage of your benefit, a larger starting benefit gets a larger dollar raise every year.
Processing Time: When You Will See the New Amount
The announcement comes first, then the notices. SSA posts the official percentage on October 14 if the schedule holds. Most people learn their exact new amount in December, either through a mailed notice or by checking the online account, where the new figure often appears early in the month. The raise takes effect for December benefits, which are paid in January 2027, and the January 1 effective date applies to SSI. If you apply for benefits this fall, standard online applications often take several weeks, while disability claims can take months.
Social Security Payment Schedule: October 2026 and January 2027
| Who you are | Payment day | October 2026 | January 2027 |
|---|---|---|---|
| Began benefits before May 1997, or get Social Security and SSI | 3rd of the month | October 2 | Check the SSA calendar for holiday timing |
| Birthday on the 1st to 10th | Second Wednesday | October 14 | January 13 |
| Birthday on the 11th to 20th | Third Wednesday | October 21 | January 20 |
| Birthday on the 21st to 31st | Fourth Wednesday | October 28 | January 27 |
SSI payments arrive on the first of the month and move earlier when that day is a weekend or holiday. Because January 1 is a federal holiday, SSI recipients should watch for a payment at the end of December.
