Social Security 2027 COLA Announcement Date: When Will the Increase Be Known?

When Will the 2027 Social Security COLA Be Known?

The key date to watch is October 14, 2026.

The Bureau of Labor Statistics has scheduled its September 2026 Consumer Price Index release for:

That September report matters because it supplies the final month of inflation data needed to calculate the 2027 Social Security cost-of-living adjustment.

Has the 2027 Social Security COLA Already Been Announced?

No.

As of October 7, 2026, Social Security has not announced the final 2027 COLA.

You may see percentages circulating in news reports, videos and social media, but they remain projections until the necessary September inflation data is available and the official calculation is completed.

Why Is October 14 So Important?

Social Security’s annual COLA is tied to inflation, but SSA does not simply use the headline inflation rate for September.

Instead, the law uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).

The calculation requires CPI-W data from the third quarter:

Once September’s figure is available, all three months required for the third-quarter calculation are known.

How Is the 2027 Social Security COLA Calculated?

SSA explains that the COLA is based on the percentage increase in the average CPI-W for the third quarter of the current year compared with the third quarter of the last year in which a COLA was determined.

In simplified form:

That is why one month’s headline CPI number by itself does not equal the Social Security COLA.

Is the September Inflation Rate the 2027 COLA?

No.

This is one of the easiest mistakes to make when the September CPI report is released.

Suppose a headline says inflation was a certain percentage over the previous 12 months. That number is not automatically the Social Security COLA.

Social Security uses the specific CPI-W third-quarter calculation required by law.

What Is the Current 2027 COLA Estimate?

Current outside estimates are generally in the mid-3% range, with widely reported forecasts around 3.5% to 3.6%.

But these numbers should be treated strictly as projections.

What Would a 3.5% or 3.6% COLA Mean?

Until the official percentage is announced, examples can help show how a possible COLA would affect gross monthly benefits.

These are illustrations only. They are not predictions of an individual’s 2027 Social Security payment and do not account for SSA rounding or deductions.

When Will the 2027 COLA Increase Start?

Social Security’s COLA rules provide for increased Social Security benefits beginning with benefits for December, which are generally paid in January 2027.

SSI timing works somewhat differently because SSI is generally paid at the beginning of the month.

Because January 1, 2027 is a federal holiday, the January SSI payment is expected under the normal payment-date rule to arrive on the preceding business day.

Do You Have to Apply for the 2027 COLA?

No.

The Social Security COLA is an automatic annual adjustment established under federal law.

Beneficiaries do not need to complete a special application or pay anyone to receive the increase.

When Will I Know My Exact 2027 Social Security Amount?

Knowing the COLA percentage is different from knowing your exact new monthly benefit.

SSA says beneficiaries receive information explaining their new benefit amount later in the year.

People with a personal my Social Security account can access their COLA notice online when SSA makes it available.

SSA also mails COLA notices during December.

Why Might My Bank Deposit Increase by Less Than the COLA?

The COLA percentage applies to the Social Security benefit calculation, but the amount actually deposited into your bank account can also be affected by deductions.

One important example is the Medicare Part B premium for beneficiaries who have that premium deducted from Social Security.

Other deductions can also affect an individual’s net payment.

Is the 2027 Medicare Part B Premium Final Yet?

Do not combine an estimated 2027 Medicare premium with an estimated COLA and present the resulting deposit as confirmed.

The final Medicare premium information and the final Social Security COLA are separate annual figures.

Beneficiaries should wait for official information before calculating their final 2027 net benefit.

Does the COLA Apply to SSDI?

Yes.

The annual COLA affects Social Security benefits, including benefits paid through the Old-Age, Survivors and Disability Insurance programs.

Therefore, eligible SSDI beneficiaries receive the same COLA percentage, although the dollar increase varies according to each person’s benefit amount.

Does SSI Get the Same COLA?

The COLA also affects federal Supplemental Security Income payment standards.

The actual amount an SSI recipient receives can still depend on countable income, living arrangements and other applicable SSI rules.

2027 Social Security COLA: Quick Answers

Bottom Line

The most important date for anyone waiting for the Social Security 2027 COLA announcement is October 14, 2026.

At 8:30 a.m. Eastern Time, the Bureau of Labor Statistics is scheduled to release September’s Consumer Price Index data.

That release completes the third-quarter inflation data required for Social Security’s annual COLA calculation.

Until then, percentages such as 3.5% or 3.6% should be described as estimates rather than the official 2027 increase.

After the COLA is finalized, beneficiaries can later look for their personalized SSA notice to learn what the adjustment means for their individual monthly benefit.
