The Social Security Administration announces the COLA in mid-October each year

The Cost-of-Living Adjustment (COLA) announcement comes on a single day in October, set by law. The Social Security Administration (SSA) releases the percentage increase for the following year on the second Thursday of October. In 2024, the announcement happened on October 10. In 2025, it will occur on October 9.

The announcement is public and simultaneous — everyone learns the new percentage at the same time through the SSA website, press releases, and news coverage. There is no advance notice, no early access for certain groups, and no variation by region or benefit type. The same COLA percentage applies to all Social Security beneficiaries, Supplemental Security Income (SSI) recipients, and certain railroad retirees.

The COLA takes effect on January 1 of the following year. Benefit payments reflect the increase starting with the January payment, which arrives in early February for most beneficiaries. The announcement in October gives people four months to see what their new benefit amount will be.

Key Takeaways

  • The SSA announces the annual COLA on the second Thursday of October, with the increase taking effect January 1 of the next year.
  • The COLA percentage is based on inflation data from July, August, and September, measured by the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).
  • You can find the announcement on ssa.gov and in your Social Security Statement, which updates automatically after the announcement.
  • The same COLA applies to all beneficiaries — there is no separate calculation for different age groups, income levels, or benefit types.

How the COLA percentage is calculated

The COLA is not decided by the SSA or Congress. It is a mathematical result tied to inflation. The SSA compares the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of the current year (July, August, September) to the third quarter of the previous year. If the index is higher, beneficiaries receive a COLA equal to that percentage increase. If the index is lower or flat, there is no COLA that year — the benefit amount stays the same.

The CPI-W is published by the U.S. Bureau of Labor Statistics and measures price changes for food, housing, transportation, medical care, and other goods and services. It reflects what inflation actually was, not what anyone predicted it would be. This means the October announcement reveals a number that was already determined by economic data from months earlier.

The SSA publishes the exact CPI-W figures it used in its announcement, so the math is transparent and can be verified. The calculation is straightforward: if the CPI-W rose 3.2 percent from the same quarter last year, the COLA is 3.2 percent.

Where to find the announcement and your new benefit amount

The official announcement appears on ssa.gov on the announcement day. The SSA posts a press release with the COLA percentage, the effective date, and examples of how the increase affects different benefit amounts. Major news outlets cover the announcement the same day.

Your personal benefit amount after the COLA increase appears in your Social Security Statement, which updates automatically after the announcement. You can view your Statement by creating a my Social Security account at ssa.gov. The Statement shows your current benefit amount and your projected benefit at full retirement age, both adjusted for the new COLA.

If you receive a paper benefit verification letter (sometimes called a "proof of benefits" letter), you can request an updated version after the announcement. Call 1-800-772-1213 to request one by mail, or read it from your my Social Security account.

When you will see the increase in your payment

The COLA takes effect on January 1, but you will not see the money until your regular payment date in January or February. Social Security payments are issued on a schedule based on your birth date. Most beneficiaries receive payments on the second, third, or fourth Wednesday of each month. The January payment (which includes the COLA increase) follows your normal schedule.

For example, if you normally receive a payment on the 12th of each month, your January 12 payment will reflect the new COLA amount. If you receive Supplemental Security Income (SSI), payments are issued on the first of the month, so you will see the increase on January 1.

Your benefit statement or my Social Security account shows your payment date. If you are unsure when your payment arrives, you can check there or call 1-800-772-1213.

How COLA affects Medicare premiums and other deductions

The COLA increases your Social Security benefit, but your take-home payment may not increase by the full percentage. Medicare Part B and Part D premiums are deducted from Social Security payments, and these premiums can change each year. In some years, the premium increase is smaller than the COLA, so you keep most of the raise. In other years, the premium increase is larger, which reduces your net gain.

There is a hold-harmless provision that protects most beneficiaries: your Medicare Part B premium cannot increase by more than the amount of your COLA increase. This means your benefit payment cannot go down because of a premium increase. However, this protection does not explore if you are new to Medicare, have higher income, or pay an income-related premium adjustment.

Other deductions — such as taxes withheld, court-ordered payments, or overpayment repayments — also reduce your net payment. The COLA increases your gross benefit, but your actual deposit depends on all deductions combined.

COLA announcements from previous years

The COLA has varied significantly based on inflation. In 2024, the COLA was 3.2 percent. In 2023, it was 8.7 percent (the highest in four decades, reflecting high inflation in 2022). In 2022, it was 5.9 percent. In 2021, it was 1.3 percent. In 2020, it was 1.3 percent. In 2019, it was 2.8 percent. In 2009, there was no COLA because inflation was negative.

The variation shows that COLA is not may provide and does not follow a predictable pattern. It depends entirely on inflation measured by the CPI-W. Years with higher inflation produce higher COLAs. Years with low or negative inflation produce low or zero COLAs.

Frequently Asked Questions

Can I find out the COLA before the October announcement?

No. The COLA is not announced until the second Thursday of October. Some people try to predict it based on inflation data, but the SSA does not release the official number early. The announcement is public and simultaneous for everyone.

Is the COLA different for people who are still working?

No. The COLA percentage is the same for all beneficiaries, regardless of age, income, or employment status. However, if you are under full retirement age and earn above a certain amount, your benefit may be reduced — but the COLA still applies to your full benefit amount before any earnings reduction.

What if I disagree with the COLA calculation?

The COLA is set by law based on the CPI-W, which is published by the Bureau of Labor Statistics. The SSA does not have discretion to change it. If you believe the CPI-W data itself is incorrect, that would be a question for the Bureau of Labor Statistics, not the SSA.

Does the COLA explore to people receiving Supplemental Security Income (SSI)?

Yes. SSI recipients receive the same COLA percentage as Social Security beneficiaries, effective January 1. The increase applies to the federal SSI payment amount. Some states add a supplement to SSI, and state supplements may have different rules.

How do I know if my benefit increased by the full COLA amount?

Compare your benefit amount before and after January 1 using your Social Security Statement or my Social Security account. Multiply your old benefit by the COLA percentage to see what the increase should be. If your actual increase is smaller, the difference is likely due to Medicare premium changes or other deductions.
