The Social Security Administration 2027 adjustment is now expected to land between 3.5% and 3.6%, which would be the largest cost-of-living raise in three years. AARP lifted its forecast to 3.6%, which would add about $75 a month for the average retired worker, while The Senior Citizens League called 3.5% its final estimate after the August inflation data. SSA will confirm the official number on October 14, the same day the Bureau of Labor Statistics releases the September inflation report, and the new rate takes effect on January 1, 2027. Until that release, every figure is a projection built from two of the three months that count. We’ll be updating this article monthly.
The reason the Social Security COLA 2027 figure is still moving is simple. The Social Security Administration will not set it until the September inflation report arrives. That report is due October 14, and SSA will announce the official increase the same day, with the new rate taking effect on January 1, 2027. Until then, every number you see online is a projection built from two of the three months that count. That includes the numbers in this article, which we will keep current. We’ll be updating this article monthly.
What Is the Social Security COLA 2027 and Why Does It Matter?
The cost-of-living adjustment is the yearly raise applied to Social Security retirement, survivor and disability benefits, and to Supplemental Security Income. Congress wrote it into law so that benefits would not lose ground as prices climb. The Social Security Administration calculates it with a fixed formula, so no official can choose a number.
For 2026, the COLA was 2.8%. In 2025 it was 2.5% and in 2024 it was 3.2%. The 2023 adjustment of 8.7% remains the biggest in about four decades. Over the past ten years the COLA has averaged roughly 3.1%. A 3.5% or 3.6% result would therefore sit modestly above the recent norm and well above last year.
For a household living mostly on one monthly deposit, even half a point matters. On a $2,000 check, it is the difference between an extra $70 and an extra $80 each month.
Social Security COLA 2027 Forecast Latest Estimates
Several groups publish projections, and they use different models. Here is where they stand as of October 1, 2026.
| Source | 2027 COLA estimate | Notes |
|---|---|---|
| The Senior Citizens League | 3.5% | Final prediction after August inflation data, down from 3.6% in August |
| AARP | 3.6% | Raised from 3.5%, about $75 more per month for the average retired worker |
| Kiplinger (David Payne) | 3.6% | Says high energy prices are leaking into other categories |
| Mary Johnson, independent analyst | 3.5% | Raised from 3.4% in the prior month |
| Social Security Administration | Not yet announced | Official figure due October 14 |
A note on earlier numbers. Some web pages still quote 3.8% or even 4.7%. Those figures came from spring models, when inflation looked like it was accelerating. The Senior Citizens League forecast has since eased from 3.6% in July to 3.5% in August. If you see a higher number, check its date before you plan around it.

How Is the Social Security COLA 2027 Calculated?
The formula is the same every year. SSA takes the average of the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, for July, August and September. It compares that average with the same three-month average from the prior year. The percentage difference, rounded to the nearest tenth, becomes the COLA.
Two of the three months are already known. The July CPI-W came in at 3.4% and the August reading was 3.5%. If September lands near those levels, the final answer will be close to 3.5%. A hotter September, driven by fuel or food, pushes the figure toward 3.6% or higher. A cooler reading pulls it down. Because it is an average of three months, one surprise month can only move the final result by a limited amount.
It is worth knowing that CPI-W is not the same as the headline inflation number in the news. The CPI-W tracks spending patterns of urban wage earners and clerical workers, which weights some categories differently from the index for all urban consumers. Advocates for seniors argue that neither captures older adults well, because retirees spend more on health care and housing.
Key Dates for the Social Security COLA 2027
| Event | Date |
|---|---|
| July CPI-W released | August 2026 (3.4% year over year) |
| August CPI-W released | September 11, 2026 (3.5% year over year) |
| September CPI-W released and official COLA announced | October 14, 2026 |
| COLA notices begin appearing in my Social Security accounts | Early December 2026 |
| New COLA takes effect | January 1, 2027 |
| First larger Social Security payments (retirement and survivors) | January 2027, based on your payment day |
| SSI increase | Paid at the end of December 2026 because January 1 is a holiday |
How Much Will Social Security Go Up in 2027? Example Amounts
The simplest method is to multiply your current gross benefit by the COLA and add the result. The Senior Citizens League says the average beneficiary now receives $1,940.08 a month, and a 3.5% raise would bring that to $2,007.98, an increase of $67.90. AARP uses a different base for the average retired worker, which is why its dollar figure is higher.
| Current monthly benefit | At 3.5% | At 3.6% | At 3.8% |
|---|---|---|---|
| $1,000 | $1,035 | $1,036 | $1,038 |
| $1,500 | $1,552 | $1,553 | $1,557 |
| $1,940 | $2,007 | $2,009 | $2,013 |
| $2,500 | $2,587 | $2,590 | $2,595 |
| $3,500 | $3,622 | $3,626 | $3,633 |
SSA rounds each benefit down to the nearest whole dollar after applying the increase, so your award letter may differ from this table by a dollar. The calculator that goes with this article does that rounding for you, and it lets you plug in your own Medicare premium.

Social Security COLA 2027 Calculator
Use the calculator embedded here to test your own numbers. Enter your current monthly benefit before deductions, pick a COLA, and add your Medicare Part B premium. The tool shows your new gross benefit, the yearly increase, and a net comparison after Medicare. Try 3.5% and 3.6% side by side, then come back after October 14 and enter the official figure.
Social Security COLA 2027 Calculator
Estimate your 2027 monthly benefit. Forecasts are not official until SSA announces the COLA on October 14.
| New monthly benefit (gross) | |
| Monthly increase | |
| Yearly increase | |
| Check after Part B, today | |
| Check after Part B, 2027 | |
| Real take home change per month |
Estimate only. SSA rounds benefits down to the whole dollar after applying the COLA. Part B is deducted for most beneficiaries, and the 2027 premium has not been announced.
Will Medicare Part B Eat Your 2027 Social Security Increase?
This is the question that most readers care about, and it deserves a straight answer. Most beneficiaries have the Part B premium taken directly from their Social Security payment. When the premium rises faster than the COLA, the raise feels smaller than it looks.
That happened this year. The Part B premium rose 9.7% for 2026 while the COLA lifted benefits by only 2.8%. The standard premium moved to $202.90 a month. The 2027 premium has not been announced yet. It is usually published in the fall, and it could change the real value of the raise. If the premium rises again by a high single-digit percentage, a noticeable share of your increase would go to Medicare.
There is one protection worth knowing. A hold harmless rule generally prevents your Social Security check from shrinking in dollars because of a Part B increase, though it does not apply to everyone, including higher earners who pay income-related surcharges and people who are newly enrolled.
Buying Power: Why Seniors Say the COLA Still Falls Short
Even a bigger COLA does not close a long gap. The Senior Citizens League says benefits are worth only about 86.3 cents on the dollar compared with 2016, and that payments would need to rise by 15.7%, or $295.85 a month for the average beneficiary, to recover that loss. That is an advocacy group calculation, and it relies on its own inflation measure, but the direction is consistent with what many retirees report.
Supporters of reform point to the CPI-E, an experimental index that weights older adults’ spending, and to bills in Congress that would change the formula or raise minimum benefits. None of those proposals is law, and none will change the 2027 COLA. The number you see on October 14 will come from CPI-W.
What Is Pushing the Forecast Higher?
Energy is the main driver. Fuel and utility costs rose sharply earlier this year, and that raised the overall index. Analysts also note that higher energy prices spread to transportation, food and shipping, which keeps other categories elevated. Kiplinger’s economist says high energy prices bleed into other categories.
The path of the forecast tells the story. Early in the year, projections hovered around 2.5% to 2.8%. They jumped to the high 3s in the spring as inflation data came in hot, then eased over the summer as monthly readings cooled slightly. That is why the number is now 3.5% to 3.6% and not 3.8% or more.

How to Apply for Social Security and Get the 2027 COLA
You do not apply for the COLA. It is added to your benefit automatically. If you already receive benefits, you do nothing. If you have not applied yet, the COLA will be applied to your benefit once you start, as long as you are eligible.
Here is how to apply for retirement benefits.
- Create or sign in to your my Social Security account at the official SSA site.
- Review your earnings record and your estimated benefit.
- Choose a start date. Claiming at 62 gives a smaller monthly check, and waiting to full retirement age or 70 increases it.
- Submit the online application, or call SSA or visit a local office if you prefer.
- Upload or mail any documents SSA requests, such as proof of age or military service.
Processing Time for Social Security Applications
SSA says retirement claims are often decided in about a month after a complete application is filed, but time varies by case. Disability applications take much longer, often several months, and appeals take longer still. Delays are common when documents are missing, so gather your birth certificate, tax forms and bank details before you start. You can check status online through your account or by calling the national number.
Social Security Payment Schedule for January 2027
Payment timing depends on your birth date and the date you first started receiving benefits.
| Group | January 2027 payment date |
|---|---|
| Started benefits before May 1997, or receive both SSI and Social Security | Based on the 3rd of the month, which falls on a weekend and a holiday, so it moves earlier |
| Birthday on the 1st to the 10th | Wednesday, January 13 |
| Birthday on the 11th to the 20th | Wednesday, January 20 |
| Birthday on the 21st to the 31st | Wednesday, January 27 |
| SSI | Paid early, on December 31, 2026, because January 1 is a holiday |
Confirm your exact date on the SSA payment calendar, because dates can shift.
Other Numbers That Change With the 2027 COLA
The COLA is not the only figure that resets each January. SSA also updates the taxable maximum, the earnings test thresholds, the quarter of coverage amount and the SSI federal rate. For 2026, the taxable maximum is $184,500, and the annual earnings test limits are $24,480 for people under full retirement age and $65,160 in the year they reach it. The 2027 values will be announced alongside the COLA. If you are still working while claiming, watch for the new earnings limit, because that determines whether benefits are temporarily withheld.
SSI recipients also get the same percentage increase. The 2026 federal payment standard is $994 for an individual, so a 3.5% raise would add roughly $35 a month, based on current rates. Rules differ for state supplements.
Taxes on Social Security in 2027
A bigger COLA can push more beneficiaries into paying federal income tax on benefits. The income thresholds that trigger taxation, $25,000 for singles and $32,000 for joint filers, have never been indexed for inflation. As benefits rise, more retirees cross those lines. Up to 85% of benefits can become taxable at higher incomes. Check IRS guidance, and consider asking a tax professional if your combined income is close to a threshold.
Practical Steps to Take Before October 14
First, treat 3.5% as a planning assumption, not a promise. Second, open your my Social Security account, confirm your address and bank details, and turn on online notices so you receive the COLA letter quickly. Third, review your Medicare costs, including Part D and any Medigap or Advantage premiums, because those are more likely to change your take-home income than the raise itself. Fourth, update your budget in January once actual amounts are posted.
