Social Security 2027 COLA: Latest Estimate, Benefit Increase & Payment Changes

Last Updated: September 3, 2026

The Social Security 2027 COLA is currently expected to be larger than the 2.8% cost-of-living adjustment beneficiaries received for 2026, but the final percentage has not yet been determined.

The Senior Citizens League currently forecasts a 3.6% Social Security 2027 COLA, while AARP estimates the increase could be 3.5%. Both numbers are projections rather than an official Social Security Administration announcement.

The final adjustment depends on the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, for July, August and September 2026.

July has already provided the first critical number. The CPI-W reached 327.104 in July 2026, representing a 3.4% increase from July 2025. August CPI data are scheduled for September 11, followed by September data on October 14.

Those remaining inflation readings will determine whether the Social Security 2027 COLA stays near the current 3.5%–3.6% forecast range, moves higher or comes in lower.

Quick Answer

The Social Security 2027 COLA has not been officially announced. Current forecasts provide a useful planning range, but beneficiaries should not treat 3.5% or 3.6% as a guaranteed increase until the third-quarter CPI-W calculation is complete.

As of September 3, 2026:

SSA says the latest official COLA remains 2.8% for 2026 and that the next COLA will be announced in October 2026.

If the final Social Security 2027 COLA is 3.6%, a beneficiary receiving $2,000 per month could see a simple gross increase of approximately $72 per month, bringing the estimated benefit to about $2,072 before Medicare premiums, taxes and other deductions.

Key Takeaways

The Social Security 2027 COLA will affect millions of retirement, disability, survivor and SSI recipients. Several important figures are already available, but the final percentage and many related 2027 Social Security limits remain unconfirmed.

• The current Social Security 2027 COLA forecast is approximately 3.5% to 3.6%.
• The official percentage has not yet been announced.
• SSA uses CPI-W data from July, August and September.
• July 2026 CPI-W was 327.104.
• August CPI data are scheduled for September 11.
• September CPI data are scheduled for October 14.
• A 3.6% COLA would add about $72 to a $2,000 monthly benefit.
• Retirement, survivor and SSDI benefits receive annual COLAs.
• Federal SSI payment standards also increase with the COLA.
• Medicare Part B and Part D expenses can reduce the net increase beneficiaries keep.
• The 2027 Medicare Part D base beneficiary premium is $41.33, although actual plan premiums vary.
• SSI resource limits do not automatically increase with the COLA.
• Eligible beneficiaries do not need to separately apply for the annual COLA.

What Is the Social Security 2027 COLA?

The Social Security 2027 COLA is the annual cost-of-living adjustment that will affect Social Security and Supplemental Security Income benefits in 2027. Its purpose is to help benefits maintain purchasing power when consumer prices rise.

COLAs have been determined automatically under federal law since the 1970s.

Instead of Congress selecting an arbitrary percentage each year, SSA uses an inflation formula tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers.

The latest official COLA is 2.8% for benefits payable in 2026.

The COLA is not a bonus or a new benefit program. It is an inflation adjustment applied to eligible existing benefits.

What Is the Latest Social Security 2027 COLA Estimate?

The latest Social Security 2027 COLA estimates currently fall between approximately 3.5% and 3.6%.

The Senior Citizens League released its latest projection on August 12, 2026, forecasting a 3.6% adjustment. Its estimate has changed several times as inflation conditions have evolved.

AARP’s August analysis places the projected Social Security 2027 COLA at 3.5%. AARP estimated that such an increase would add about $73 to the average retired worker’s monthly benefit.

The difference between these forecasts shows why beneficiaries should treat every percentage released before the official October calculation as an estimate.

Is the 3.6% Social Security 2027 COLA Official?

No. The 3.6% Social Security 2027 COLA is currently a forecast, not an official SSA figure.

SSA says its next COLA will be announced in October 2026. The official adjustment cannot be determined until the CPI-W data for July, August and September are available.

Websites or social-media posts claiming the 3.6% increase has already been formally approved are therefore premature.

Why Does the Social Security Trustees Report Show a Lower 2.7% Estimate?

Some readers may encounter a 2.7% figure while researching the Social Security 2027 COLA. That number comes from the intermediate assumptions used in the 2026 Social Security Trustees Report.

The Trustees assumed a 2.7% COLA effective for December 2026, which would be payable in January 2027. It is an actuarial planning assumption rather than an official COLA announcement.

Current estimates from TSCL and AARP incorporate more recent inflation data and are therefore higher.

Once third-quarter CPI-W data are complete, SSA’s official calculation will replace all forecasts.

How Is the Social Security 2027 COLA Calculated?

The Social Security 2027 COLA is calculated by comparing the average CPI-W for July, August and September 2026 with the average CPI-W for the same three months in 2025.

SSA does not use January-to-December inflation or one month’s annual inflation rate to determine the COLA.

The basic comparison is:

Average CPI-W for Q3 2026

versus

Average CPI-W for Q3 2025

If the 2026 quarterly average is higher, the percentage increase becomes the COLA after statutory rounding.

2025 CPI-W Base

The relevant 2025 CPI-W figures are:

The 317.265 quarterly average is the comparison point used when calculating the Social Security 2027 COLA.

Why Is Headline Inflation Different From the Social Security COLA?

The inflation number most frequently reported in news headlines is usually the Consumer Price Index for All Urban Consumers, or CPI-U.

The Social Security 2027 COLA does not use CPI-U. Social Security uses CPI-W.

BLS says CPI-U covers the large majority of the U.S. population, while CPI-W represents a smaller subset of households meeting wage-earner and clerical-worker criteria.

Because their spending weights differ, CPI-U and CPI-W can produce slightly different inflation readings.

That means a headline saying inflation is 3.0% does not automatically mean Social Security’s COLA will be 3.0%.

For COLA purposes, the important figure is the not-seasonally-adjusted CPI-W during July, August and September.

What We Know About 2026 So Far

The Social Security 2027 COLA calculation is beginning to take shape because the first of the three required CPI-W readings is now available.

July 2026 CPI-W reached:

327.104

BLS reports that the CPI-W increased 3.4% from July 2025 to July 2026.

The remaining scheduled releases are:

• August 2026 CPI: September 11, 2026
• September 2026 CPI: October 14, 2026

September’s report completes the three-month period required for the official calculation.

What Would Be Needed for a 3.6% COLA?

A 3.6% Social Security 2027 COLA would correspond to a Q3 2026 CPI-W average approximately 3.6% above the Q3 2025 base of 317.265.

A simplified calculation gives:

317.265 × 1.036 = approximately 328.687

July’s CPI-W is already known at 327.104.

For the Q3 average to reach approximately 328.687, August and September together would need to average close to 329.48.

This is not a prediction of future inflation. It simply demonstrates what a 3.6% increase would look like mathematically.

Because SSA rounds the final COLA to the nearest one-tenth of one percent, the precise index range capable of producing an officially reported 3.6% COLA is somewhat wider than this simplified example.

Social Security COLA History

The Social Security 2027 COLA can be better understood by comparing it with recent annual adjustments.

A 3.6% increase would be larger than the COLAs provided for 2024, 2025 and 2026, but far below the unusually high 8.7% adjustment that took effect in 2023.

SSA’s historical records also show zero COLAs in some years, including 2010, 2011 and 2016.

How Much Could Social Security Benefits Increase in 2027?

The dollar value of the Social Security 2027 COLA depends on each beneficiary’s current payment.

If the final increase is 3.6%, a person receiving a larger benefit will receive a larger dollar increase even though the same COLA percentage applies.

These are simplified planning estimates.

SSA applies the COLA through the beneficiary’s Primary Insurance Amount, followed by applicable reductions, credits and rounding rules. The exact payment may therefore differ slightly from a simple multiplication.

Social Security 2027 COLA Calculator

A Social Security 2027 COLA calculator can help beneficiaries estimate possible payment changes before SSA sends personalized notices.

Using a 3.6% forecast:

Estimated monthly increase = Current gross monthly benefit × 0.036

Estimated new gross benefit = Current gross monthly benefit × 1.036

Example

For a $2,000 monthly benefit:

$2,000 × 0.036 = $72

Estimated new gross benefit:

$2,072

Different possible COLA scenarios would produce:

The final deposited amount can differ because Medicare premiums, tax withholding, benefit offsets and SSA calculation rules may apply.

How Much Could the Average Retired Worker Receive in 2027?

The Social Security 2027 COLA could increase the average retired-worker benefit by roughly $73 to $75 per month if current forecasts hold.

SSA’s July 2026 Monthly Statistical Snapshot reports an average retired-worker benefit of $2,085.98 per month.

At 3.6%:

$2,085.98 × 0.036 = approximately $75.10

Estimated new gross benefit:

$2,161.08 per month

Approximate annual increase:

$901.20

At AARP’s 3.5% projection, the increase would be approximately $73.01 per month.

These figures are estimates before Medicare premiums, taxes and other deductions.

How Could the 2027 COLA Affect Different Beneficiaries?

The Social Security 2027 COLA does not apply only to retired workers. Survivor beneficiaries, disabled workers, spouses and eligible children can also receive cost-of-living adjustments.

Using July 2026 SSA averages and a hypothetical 3.6% increase:

SSA’s July 2026 data confirm these current average benefit levels.

The table should be used for comparison only, not as an official 2027 benefit schedule.

Will SSDI Benefits Increase in 2027?

Yes, if the Social Security 2027 COLA is positive.

Social Security Disability Insurance beneficiaries receive the same annual COLA that applies to retirement and survivor benefits.

SSA reports an average disabled-worker payment of $1,635.27 per month in July 2026.

At 3.6%, the simple increase would be:

$58.87 per month

Estimated new average:

$1,694.14

Actual SSDI payments depend on each worker’s earnings history and individual deductions or offsets.

Will SSI Increase in 2027?

The Social Security 2027 COLA also affects federal Supplemental Security Income payment standards.

For 2026, maximum federal SSI payments are:

SSA confirms these amounts and explains that future SSI rates are calculated from unrounded annual amounts.

Using those unrounded amounts, a hypothetical 3.6% increase would produce approximate maximums near:

These are estimates, not official 2027 SSI rates.

What If You Receive Both Social Security and SSI?

The Social Security 2027 COLA can have a more complicated effect on people who receive both Social Security and SSI.

Social Security generally counts as unearned income when SSA determines the SSI payment. As a result, beneficiaries should not simply calculate one COLA increase for Social Security, another for SSI and add the two together.

SSA explains that SSI payments are reduced according to countable income after applicable exclusions.

The actual result can depend on:

• Social Security income
• Other income
• Income exclusions
• Living arrangements
• State SSI supplements
• Spousal income
• Other eligibility rules

Concurrent beneficiaries should rely on their personalized SSA payment information.

Will the SSI Resource Limit Increase With the 2027 COLA?

A higher Social Security 2027 COLA does not automatically raise SSI resource limits.

The current federal limits are:

SSA confirms these limits and notes that the $2,000 and $3,000 thresholds have applied since 1989.

Some resources do not count, including the home a recipient lives in, certain personal belongings and one qualifying vehicle.

The SSI resource test is therefore separate from the annual COLA calculation.

When Will the Official Social Security 2027 COLA Be Announced?

The official Social Security 2027 COLA will be announced in October 2026.

SSA has not yet published the final percentage.

Two critical inflation dates remain.

September 11, 2026

BLS is scheduled to release August CPI data.

That will provide the second of the three CPI-W readings used in the calculation.

October 14, 2026

BLS is scheduled to publish September CPI data.

Once September’s CPI-W becomes available, all three third-quarter figures needed for the Social Security 2027 COLA calculation will be known.

When Will the 2027 COLA Start?

The Social Security 2027 COLA will apply to Social Security benefits for December 2026, which are normally paid in January 2027.

SSA follows this pattern each year. The 2.8% 2026 COLA became effective with December 2025 Social Security benefits payable in January 2026.

SSI follows a slightly different timetable because January SSI payments are generally advanced to the previous business day when January 1 is a federal holiday.

Social Security 2027 Payment Schedule

The Social Security 2027 COLA changes benefit amounts, but it does not replace the normal SSA payment schedule.

For many beneficiaries who began receiving Social Security after April 1997:

• Birthdays from the 1st through 10th are generally paid on the second Wednesday.
• Birthdays from the 11th through 20th are generally paid on the third Wednesday.
• Birthdays from the 21st through 31st are generally paid on the fourth Wednesday.

SSA has already published its official 2027 payment calendar.

2027 Social Security Payment Dates

People who received Social Security before May 1997 and some concurrent Social Security/SSI beneficiaries can follow different schedules.

Could Medicare Reduce the 2027 COLA Increase?

Yes. The gross increase created by the Social Security 2027 COLA may be larger than the additional amount a beneficiary actually receives in their bank account.

Medicare Part B is one important reason.

The standard Part B premium is $202.90 per month in 2026. The 2026 Medicare Trustees Report estimates a standard premium of $209.50 for 2027, although that amount is still a projection rather than the final 2027 premium.

That would represent an estimated increase of:

$6.60 per month

Example

Suppose a retiree receives $2,000 per month.

A 3.6% Social Security 2027 COLA would add:

$72

If the standard Part B premium increased by $6.60:

$72 − $6.60 = $65.40

The beneficiary would keep approximately $65.40 of the gross COLA increase before considering other deductions.

How Could Medicare Part D Affect the Social Security 2027 COLA?

The Social Security 2027 COLA should also be considered alongside prescription-drug costs.

CMS has officially set the 2027 Medicare Part D national base beneficiary premium at $41.33, compared with $38.99 for 2026. This is a calculation benchmark and should not be confused with the premium every enrollee will actually pay.

Important Part D figures include:

Actual Part D premiums vary by plan and location.

Higher-income beneficiaries may also pay Income-Related Monthly Adjustment Amounts, or IRMAA, for Medicare Part B and Part D.

Therefore, the amount of the Social Security 2027 COLA a beneficiary effectively keeps can depend on:

• Part B premiums
• Part D premiums
• Part B IRMAA
• Part D IRMAA
• Medicare Advantage costs
• Prescription expenses
• Other deductions

What Is the Medicare Hold-Harmless Rule?

The Medicare Part B hold-harmless provision can protect many beneficiaries when Medicare premiums rise alongside the Social Security 2027 COLA.

For people who qualify, the dollar increase in the Part B premium generally cannot exceed the dollar increase in their Social Security benefit caused by the COLA.

The Medicare Trustees confirm that the rule applies to many beneficiaries whose Part B premium is deducted directly from Social Security.

Not everyone receives the same protection.

Different rules can apply to:

• New Medicare beneficiaries
• Higher-income beneficiaries paying IRMAA
• Certain Medicaid beneficiaries
• People whose Part B premium is not withheld from Social Security in the required manner

Could the 2027 COLA Increase Taxes on Social Security Benefits?

A larger Social Security 2027 COLA could increase the taxable portion of benefits for some households.

SSA says up to 85% of Social Security benefits may be subject to federal income tax, depending on filing status and combined income.

Combined income generally includes:

• Adjusted gross income
• Tax-exempt interest
• Half of annual Social Security benefits

For individuals with combined income above $34,000 and couples filing jointly above $44,000, up to 85% of benefits can become taxable.

A COLA does not mean 85% of benefits will automatically be taxed. It means up to that share can be included in taxable income depending on the household’s circumstances.

Will Social Security’s Earnings Limit Change in 2027?

The Social Security 2027 COLA announcement is often accompanied by updates to other program amounts, including the retirement earnings test.

Official 2027 earnings limits have not yet been announced.

For 2026:

• Workers under full retirement age can earn up to $24,480 before withholding begins.
• Workers reaching full retirement age during 2026 have a higher limit of $65,160 for earnings before the month they reach full retirement age.

These limits are wage-indexed, so they are calculated differently from the CPI-W-based COLA.

Will the Social Security Taxable Maximum Increase in 2027?

The maximum amount of annual earnings subject to Social Security payroll tax can also change in 2027.

For 2026, the taxable maximum is:

$184,500

SSA confirms this in its 2026 automatic-determination information.

The 2027 taxable maximum has not yet been officially determined.

It is tied primarily to changes in the national average wage index, not directly to the Social Security 2027 COLA.

What Other Social Security Limits Could Change in 2027?

The Social Security 2027 COLA is only one of several Social Security figures that beneficiaries and workers should watch.

Official 2026 amounts provide the current baseline:

SSA publishes many of these automatic determinations each year.

Readers should watch for official 2027 updates to:

• Maximum taxable earnings
• Retirement earnings limits
• Maximum retirement benefits
• Quarter-of-coverage requirements
• Disability SGA amounts
• Trial Work Period thresholds
• SSI federal benefit rates
• SSI student earned-income exclusions

These amounts are not all calculated directly from the COLA.

Does the Social Security 2027 COLA Change Full Retirement Age?

No. The Social Security 2027 COLA and full retirement age are separate parts of Social Security.

For people born in 1960 or later, full retirement age is 67.

Starting retirement benefits before full retirement age can permanently reduce the monthly benefit, while delaying beyond full retirement age can increase benefits through delayed retirement credits.

The COLA adjusts benefits for inflation but does not change a person’s statutory full retirement age.

Does Claiming Social Security Early Mean You Miss Future COLAs?

No. Beneficiaries who claim retirement early can still receive future cost-of-living adjustments, including the Social Security 2027 COLA when applicable.

However, early claiming reduces the underlying monthly benefit.

Future COLAs increase that reduced amount; they do not undo the permanent reduction caused by claiming before full retirement age.

For someone whose full retirement age is 67, claiming at age 62 can reduce the retirement benefit substantially.

Do You Get the 2027 COLA If You Have Not Claimed Social Security Yet?

A worker does not necessarily need to already be receiving retirement checks to benefit from the Social Security 2027 COLA.

For retirement calculations, Social Security generally considers a worker first eligible at age 62.

SSA’s calculation examples show that COLAs after initial eligibility can be incorporated into the Primary Insurance Amount even when the person delays claiming benefits.

SSA also notes that someone first eligible in 2026 could receive their first applicable COLA effective for December 2026.

Claiming age still matters separately because:

• Early retirement can reduce monthly benefits.
• Delaying beyond full retirement age can increase benefits.
• COLAs adjust eligible benefit amounts for inflation.

Why Your Exact Increase May Be Different From 3.6%

Even if the final Social Security 2027 COLA is exactly 3.6%, a beneficiary should not assume:

Current bank deposit × 1.036 = exact new bank deposit

SSA first applies the COLA through the person’s benefit calculation.

The final amount can then be affected by:

• Medicare Part B premiums
• Part D deductions
• IRMAA
• Federal tax withholding
• Benefit offsets
• Garnishments
• Early retirement reductions
• Delayed retirement credits
• SSA rounding procedures

The gross COLA increase can therefore differ from the net increase deposited into a beneficiary’s account.

When Will You Know Your Exact 2027 Social Security Benefit?

Beneficiaries will know their exact payment after the Social Security 2027 COLA is finalized and SSA updates individual benefit records.

For the 2026 COLA, SSA mailed notices throughout December, while many beneficiaries could also view updated information through their my Social Security accounts.

Personalized notices can show:

• New gross monthly benefit
• Medicare deductions
• Other deductions
• Net monthly payment
• Effective date

SSA has not yet published the complete personalized-notice schedule for the 2027 adjustment.

Why the COLA May Still Feel Too Small

Even a 3.5% or 3.6% Social Security 2027 COLA may not make beneficiaries feel significantly wealthier.

The purpose of the adjustment is primarily to compensate for inflation. If living costs rise by approximately the same percentage, much of the increase simply restores purchasing power.

Retirees may also spend a large portion of their budgets on categories that behave differently from overall inflation, including:

• Housing
• Rent
• Property taxes
• Home insurance
• Medical care
• Prescription drugs
• Medicare premiums
• Food
• Utilities
• Transportation
• Long-term care

A national inflation index cannot perfectly represent every household’s individual spending experience.

Why Doesn’t Social Security Use CPI-E?

Debate over the Social Security 2027 COLA frequently includes questions about whether CPI-W accurately reflects retiree expenses.

One alternative discussed by policymakers is the Consumer Price Index for Americans 62 years of age and older, commonly referred to as CPI-E.

Supporters argue that older Americans may spend relatively more on health care and housing than working-age households.

Current law, however, continues to base Social Security COLAs on CPI-W.

Changing the index would require federal legislation.

What Happens if Inflation Falls Before September?

The final Social Security 2027 COLA can come in below current forecasts if inflation weakens during August and September.

It can also move higher if price growth accelerates.

This is why TSCL’s forecast has moved during 2026:

• April: 2.8%
• May: 3.9%
• June: 3.8%
• July: 3.8%
• August: 3.6%

The final two third-quarter CPI-W readings matter more than projections made earlier in the year.

Can the Social Security 2027 COLA Be Zero?

Yes. The Social Security 2027 COLA could theoretically be 0% if the required CPI-W comparison did not produce an increase.

Federal law does not create a negative COLA that reduces Social Security benefits because prices fall.

SSA’s historical records show zero COLAs for:

• January 2010
• January 2011
• January 2016

Current forecasts around 3.5%–3.6% make a zero COLA appear unlikely for 2027, but the official calculation has not yet been completed.

What Should Beneficiaries Do Before the 2027 COLA Is Announced?

Beneficiaries do not need to apply separately for the Social Security 2027 COLA. Eligible benefits are automatically adjusted after SSA determines the official percentage.

Before October, beneficiaries can:

• Check access to their my Social Security account.
• Review their current gross monthly benefit.
• Review Medicare Part B deductions.
• Check Part D plan premiums and coverage.
• Review federal tax withholding.
• Follow August and September CPI-W reports.
• Compare the eventual COLA with Medicare premium changes.
• Wait for SSA’s official percentage before making major budget decisions.
• Watch for their personalized COLA notice.
• Avoid scams claiming payment is required to receive the increase.

The annual COLA does not require beneficiaries to pay a fee or provide banking information to an outside party.

Does the 2027 COLA Solve Social Security’s Funding Problem?

No. The Social Security 2027 COLA and the program’s long-term trust-fund finances are separate issues.

The 2026 Trustees Report projects that the Old-Age and Survivors Insurance Trust Fund can pay scheduled benefits in full until the fourth quarter of 2032.

If no legislative changes were made, continuing income would be sufficient to pay approximately 78% of scheduled OASI benefits at depletion.

On a hypothetical combined OASI and DI basis, reserves are projected to support full scheduled benefits until 2034, with about 83% payable at depletion under the Trustees’ intermediate assumptions.

This does not mean benefits will suddenly be cut in 2027.

The annual COLA will continue to be determined under current law unless Congress changes the program.

Social Security 2027 COLA Forecast at a Glance

The table below summarizes the most important Social Security 2027 COLA figures currently available.

Social Security 2027 COLA FAQs

1. What is the expected Social Security 2027 COLA?

The latest Social Security 2027 COLA forecasts are approximately 3.5% to 3.6%. TSCL projects 3.6%, while AARP currently estimates 3.5%. Neither figure is official.

2. Has the Social Security 2027 COLA been officially announced?

No. SSA says it will announce the next COLA in October 2026 after the necessary third-quarter inflation data become available.

3. How much would a 3.6% COLA add to a $2,000 benefit?

A simple 3.6% calculation would add approximately $72 per month, increasing a $2,000 gross monthly benefit to approximately $2,072 before Medicare premiums, taxes and other deductions.

4. When will the Social Security 2027 COLA begin?

The Social Security 2027 COLA will apply to December 2026 Social Security benefits, normally paid in January 2027. SSI recipients follow a slightly different payment schedule.

5. Will SSDI recipients receive the Social Security 2027 COLA?

Yes. SSDI benefits receive the annual Social Security cost-of-living adjustment. The percentage is the same, although individual dollar increases vary based on each person’s benefit.

6. Will SSI payments increase in 2027?

A positive Social Security 2027 COLA also raises the federal SSI payment standard. The exact 2027 SSI maximum cannot be confirmed until the official COLA is determined.

7. Will Medicare reduce my 2027 Social Security increase?

It can. Medicare Part B premiums are commonly deducted from Social Security payments, while Part D premiums and IRMAA can also affect some beneficiaries. The gross COLA increase can therefore be larger than the increase in take-home income.

8. Can the Social Security 2027 COLA be zero?

Yes in theory, although current inflation data and forecasts point toward a positive adjustment. Social Security has had zero-COLA years before, including 2010, 2011 and 2016.

Conclusion

The Social Security 2027 COLA is currently expected to be higher than the 2.8% adjustment beneficiaries received for 2026, but the final increase has not yet been confirmed.

Current projections place the Social Security 2027 COLA at approximately 3.5% to 3.6%. If the final adjustment is 3.6%, a $2,000 monthly Social Security benefit could rise by about $72 per month, while the July 2026 average retired-worker benefit of $2,085.98 could increase by approximately $75 per month before deductions.

The final percentage depends on the remaining third-quarter CPI-W data. August inflation figures are scheduled for September 11, 2026, followed by September figures on October 14, 2026. Those releases will complete the three-month period required for the official calculation.

Beneficiaries should also look beyond the headline percentage. Medicare Part B premiums, Part D costs, IRMAA, federal taxes, SSI income rules and other deductions can affect how much additional money actually reaches a household.

For now, 3.6% remains a useful Social Security 2027 COLA planning estimate rather than a confirmed increase.

The official Social Security 2027 COLA will become clear once the final third-quarter inflation data are available and SSA publishes its October announcement.
