The latest Social Security COLA 2027 forecast points to a potentially larger benefit increase than beneficiaries received in 2026. AARP currently projects a 3.6% cost-of-living adjustment for 2027 based on the latest inflation data, while other forecasts are clustered around the mid-3% range. However, the number is not official yet.
The final Social Security cost-of-living adjustment will depend on September 2026 inflation data. The Bureau of Labor Statistics (BLS) is scheduled to release that data on October 14, 2026, when the Social Security Administration (SSA) is expected to announce the official 2027 COLA.
For now, the most useful takeaway is simple: a 3.6% COLA would mean roughly $36 more per month for every $1,000 in current Social Security benefits. The actual dollar increase will depend on each person’s benefit amount.
What Is the Social Security COLA for 2027?
The official 2027 Social Security COLA has not been finalized as of September 15, 2026.
The latest AARP estimate puts the increase at 3.6%. The estimate is based on the inflation measure used by Social Security and the available July and August 2026 data, combined with a projection for September.
Other forecasts have been slightly different. Recent estimates include approximately 3.4% from the Committee for a Responsible Federal Budget and 3.5% from the Senior Citizens League, showing that the final number could still move before the official announcement.
The 2026 COLA was 2.8%, so a 3.6% increase would represent a noticeable step up for beneficiaries. SSA’s official COLA history confirms the 2.8% adjustment for 2026.
Current 2027 COLA outlook
| Estimate/source | 2027 projected COLA |
|---|---|
| AARP | 3.6% |
| Senior Citizens League | 3.5% |
| Committee for a Responsible Federal Budget | About 3.4% |
| Official SSA COLA | Not yet announced |
These are forecasts, not guaranteed benefit increases.
Why Is the COLA Estimate Around 3.6%?
The main reason is continued inflation.
The Social Security COLA is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called the CPI-W. The BLS reported that CPI-W was 3.5% higher in August 2026 than in August 2025.
The broader CPI-U, another major inflation measure, increased 3.4% over the year in August 2026. Gasoline prices were also a significant contributor to the monthly increase, with the gasoline index rising 3.9% in August.
For Social Security recipients, inflation in necessities can be especially important. Housing, food, energy, transportation and health-related expenses can consume a large portion of retirement income, particularly for households relying heavily on fixed monthly benefits.
That does not mean every price is rising at the same rate. Rather, the COLA is determined by the specific inflation formula written into federal law.
How Is the Social Security COLA Calculated?
The Social Security Administration does not simply use the annual inflation rate reported in a headline.
Instead, the calculation uses the CPI-W during the third quarter of the year.
The formula compares the average CPI-W for July, August and September 2026 with the average CPI-W for the third quarter of the last year in which a COLA became effective.
For the 2027 adjustment, September is therefore the missing piece.
In simplified form:
2027 COLA = (2026 third-quarter average CPI-W − comparison third-quarter average CPI-W) ÷ comparison average × 100
The result is rounded to the nearest one-tenth of a percentage point. SSA explains that the CPI-W is calculated monthly by the BLS and is the legally specified inflation measure for Social Security COLAs.
Why September inflation matters
July and August data are already available, but September’s CPI-W reading has not yet been released.
That means a significant change in September inflation could push the final COLA either higher or lower than current estimates.
This is why the 3.6% Social Security COLA estimate should be treated as a preliminary forecast rather than a guaranteed increase.
What Is the Latest CPI-W Inflation Data?
The latest available BLS figures show that CPI-W increased 3.5% over the year through August 2026. On a monthly basis, CPI-W increased 0.4% before seasonal adjustment and 0.5% on a seasonally adjusted basis in August.
The BLS has scheduled the September 2026 CPI release for October 14, 2026, at 8:30 a.m. Eastern Time.
That release is particularly important for Social Security beneficiaries because September is the final month needed for the third-quarter CPI-W calculation.
When Will the Official 2027 COLA Be Announced?
The official 2027 Social Security COLA is expected to be announced on October 14, 2026.
That is when the September inflation figures are scheduled to be released, allowing the SSA to complete the third-quarter calculation. AARP also identifies October 14 as the expected announcement date.
Until then, estimates from AARP, financial organizations and other analysts should not be confused with the official Social Security benefit adjustment.
How Much Could Social Security Benefits Increase in 2027?
If the final COLA is 3.6%, beneficiaries would multiply their current monthly benefit by 1.036.
For example:
| Current monthly benefit | Approx. increase at 3.6% | New monthly amount |
|---|---|---|
| $1,000 | $36 | $1,036 |
| $1,500 | $54 | $1,554 |
| $2,000 | $72 | $2,072 |
| $2,500 | $90 | $2,590 |
| $3,000 | $108 | $3,108 |
| $4,000 | $144 | $4,144 |
These are simple estimates before considering deductions or other changes.
AARP says the average retired-worker Social Security benefit was about $2,086 per month in July 2026. A 3.6% COLA would increase that average by approximately $75 per month.
Your own increase could be substantially different because Social Security benefits vary widely.

For a quick estimate, the following chart shows what a 3.6% adjustment would look like:
| Current benefit | 3.6% increase | Estimated 2027 benefit |
|---|---|---|
| $1,200 | $43.20 | $1,243.20 |
| $1,500 | $54.00 | $1,554.00 |
| $1,800 | $64.80 | $1,864.80 |
| $2,000 | $72.00 | $2,072.00 |
| $2,086 | $75.10 | $2,161.10 |
| $2,500 | $90.00 | $2,590.00 |
| $3,000 | $108.00 | $3,108.00 |
| $4,000 | $144.00 | $4,144.00 |

Social Security COLA 2027 Estimate Calculator
You can make a simple preliminary estimate without a special calculator.
Estimated 2027 benefit = current monthly benefit × 1.036
For example, if your current Social Security check is $1,800:
$1,800 × 1.036 = $1,864.80
That represents an estimated increase of $64.80 per month, or approximately $777.60 over 12 months.
The calculation will change if the final COLA is different from 3.6%.
Will SSDI and Survivor Benefits Also Increase?
Yes. The annual COLA generally applies to Social Security retirement benefits as well as Social Security Disability Insurance (SSDI) and survivor benefits.
AARP estimates that a 3.6% adjustment would increase the average SSDI benefit by roughly $59 per month, based on an average benefit of about $1,635. It estimates an increase of approximately $70 for an average surviving spouse benefit of about $1,933.
The exact increase for an individual depends on the person’s benefit amount.
This means eligible retirement beneficiaries, disabled workers and qualifying survivors can all see their monthly payments adjusted when the annual COLA takes effect.
When Will Higher 2027 Social Security Payments Start?
The 2027 COLA is expected to become effective with December 2026 Social Security benefits, which are generally paid in January 2027.
SSA explains that, since 1982, Social Security COLAs have been effective with benefits payable for December and received by beneficiaries in January.
SSI follows a different payment schedule. SSI payments are generally made at the beginning of the month, so the timing can differ from regular Social Security retirement or SSDI payments.
Beneficiaries should therefore pay attention to their individual payment schedule rather than assuming everyone receives the increase on the same day.
Why Could the 2027 COLA Be Higher or Lower Than Expected?
The biggest reason is the September CPI-W reading.
Current estimates are based on incomplete third-quarter data. If September inflation is stronger than projected, the final COLA could come in above current estimates. If inflation is weaker, the final adjustment could be lower.
Several factors can influence the inflation picture, including:
- Energy and gasoline prices
- Food prices
- Housing and rent costs
- Medical-care expenses
- Transportation costs
- Tariffs and import costs
- Broader consumer-price trends
The August BLS report showed overall CPI inflation at 3.4% year over year, while gasoline prices were a notable contributor to the monthly increase.
Does a Higher COLA Mean Social Security Recipients Are Better Off?
Not necessarily.
A larger COLA means a larger nominal monthly payment, but it does not automatically mean beneficiaries have gained purchasing power.
For example, if a person’s Social Security benefit rises 3.6% while the prices of the goods and services they regularly purchase rise by a similar amount, much of the additional income may simply cover higher living costs.
This issue is particularly important for older Americans living on fixed incomes. The CPI-W is designed to track the spending patterns of urban wage earners and clerical workers, rather than specifically measuring the spending patterns of elderly households.
That is one reason some advocates have proposed using the CPI-E, an experimental inflation measure designed around spending by older Americans. However, CPI-E is not currently the official measure used to calculate Social Security COLAs. SSA states that CPI-W is the legally specified measure.
What Should Social Security Beneficiaries Do Now?
There is no need to change a Social Security claim because of a preliminary COLA forecast.
Instead, beneficiaries can use the current estimate for planning while waiting for the official announcement.
Consider these steps:
- Check your current monthly benefit. Use your actual benefit amount rather than the national average.
- Calculate several scenarios. Try 3.4%, 3.5% and 3.6% to create a reasonable planning range.
- Watch the October 14 inflation release. September CPI data will provide the final piece of the COLA calculation.
- Review Medicare deductions. A higher gross Social Security benefit does not necessarily translate into the same increase in the amount deposited into your bank account.
- Update your 2027 budget after the official COLA is announced. Avoid treating a preliminary forecast as guaranteed income.
Social Security COLA 2027 Estimate Update: What to Watch
As of September 15, 2026, the best-known forecast is AARP’s 3.6% estimate, but there is still one crucial inflation report left.
The sequence is straightforward:
August CPI-W data → September CPI-W data → SSA calculation → official October announcement → higher payments in 2027
The final number could differ from today’s forecast because September inflation has not yet been incorporated into the official calculation.
The latest BLS data already show inflation remains elevated enough to support a mid-3% COLA forecast.
Bottom Line: What Is the Projected COLA for 2027?
The latest Social Security COLA 2027 forecast is about 3.6%, according to AARP, with other current estimates generally falling between roughly 3.4% and 3.5%.
But 3.6% is not yet official.
The final Social Security inflation adjustment will be based on July, August and September 2026 CPI-W data. The September figure is scheduled for release on October 14, 2026, when the official 2027 COLA is expected to be announced.
If the final adjustment is 3.6%, someone receiving $2,000 per month would receive approximately $72 more per month, while the average retired-worker benefit of about $2,086 would rise by roughly $75 per month.
For now, beneficiaries should treat the 3.6% figure as a useful planning estimate—not a promise.

Frequently Asked Questions
What is the projected COLA for 2027?
The latest AARP projection is 3.6%. Other estimates are slightly lower, so the final COLA could change before the Social Security Administration announces the official figure.
When will the official 2027 Social Security COLA be announced?
The official 2027 COLA is expected on October 14, 2026, following the release of September 2026 inflation data.
How is the Social Security COLA calculated?
SSA uses the CPI-W, comparing the average CPI-W for July, August and September with the applicable comparison period from the previous COLA year. The resulting percentage is rounded to the nearest one-tenth of a percentage point.
How much could my Social Security check increase with a 3.6% COLA?
Multiply your current monthly benefit by 0.036 to estimate the increase. For example, a $2,000 benefit would rise by about $72, producing an estimated monthly benefit of $2,072.
Will SSDI benefits increase in 2027?
If the official 2027 COLA is positive, eligible SSDI beneficiaries generally receive the annual cost-of-living adjustment as well. The exact increase depends on the individual’s benefit amount.
Is the 3.6% Social Security COLA official?
No. As of September 15, 2026, 3.6% is a forecast from AARP, not the official COLA. September CPI-W data are still needed before SSA can finalize the adjustment.
When will increased Social Security payments begin?
The 2027 COLA is expected to apply to benefits payable for December 2026, which beneficiaries generally receive in January 2027.
Does the COLA guarantee that Social Security beneficiaries will have more purchasing power?
No. COLA is intended to offset inflation, not necessarily increase real purchasing power. If prices rise at a similar rate, the additional benefit may largely cover higher living expenses.
Why is CPI-W used instead of CPI-E?
Federal law currently specifies the CPI-W for Social Security COLA calculations. CPI-E is an alternative experimental index intended to reflect spending patterns of older Americans, but it is not currently the official COLA measure.
What is the Social Security COLA 2027 estimate calculator?
A simple estimate calculator can multiply your current monthly Social Security benefit by 1.036 if you want to model a hypothetical 3.6% COLA. The result is only a forecast until SSA announces the official adjustment.
