What the Cost of Living Adjustment (COLA) is and who receives it

The Cost of Living Adjustment (COLA) is an annual increase to Social Security payments meant to keep up with inflation. Every October, the Social Security Administration announces whether there will be a raise for the following year, and by how much. The raise takes effect in January.

If you receive Social Security retirement, disability (SSDI), or survivor benefits, you get the COLA automatically — you do not have to do anything. The raise appears in your January payment. Supplemental Security Income (SSI) recipients also receive COLA, though the timing and rules differ slightly.

Not everyone gets a raise every year. COLA only happens when inflation has pushed prices up enough to trigger one. In years with very low inflation, there is no COLA. The last year with no raise was 2016.

Key Takeaways

  • COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) and announced each October for the following January.
  • The raise is automatic for all Social Security beneficiaries; you receive it in your January payment with no action required.
  • COLA amounts vary year to year based on inflation and have ranged from 0% to over 8% in recent decades.
  • Your new payment amount after COLA affects Medicare premiums, SSI limits, and other benefits tied to your Social Security income.

How the COLA percentage is calculated

Social Security uses a specific inflation measure called the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to calculate COLA. This index tracks the cost of food, housing, transportation, medical care, and other goods and services that wage earners and clerical workers buy.

The Social Security Administration compares the average CPI-W for July, August, and September of the current year to the same three months from the previous year. If prices have gone up, that percentage increase becomes the COLA for the next January. If prices stayed flat or fell, COLA is 0% — no raise that year.

The announcement happens in October, giving you two months' notice before the raise takes effect. You can find the exact percentage on the Social Security Administration website or in a notice mailed to you in December.

Recent COLA amounts and what they mean for your payment

COLA varies significantly from year to year. In 2024, the COLA was 3.2%. In 2023, it was 8.7% — one of the largest raises in four decades. In 2022, it was 5.9%. These swings reflect how inflation itself moves unpredictably.

To see what your raise will be in dollars, multiply your current monthly payment by the COLA percentage. If you receive $1,500 per month and COLA is 3%, your new payment will be $1,545. The increase is added to your January payment, and your payment stays at that new amount going forward unless another COLA occurs.

Your COLA raise also affects other programs tied to your income. If you receive Medicare, your Part B premium may change. If you receive Supplemental Security Income (SSI), the federal payment limit increases, which may change what you receive. Some state programs that use Social Security income as a threshold also adjust based on COLA.

How COLA affects Medicare and other benefits

When your Social Security payment increases due to COLA, your Medicare Part B premium may increase as well. However, there is a rule called the hold-harmless provision that protects most beneficiaries. Under this rule, your Medicare Part B premium cannot increase by more than the amount of your COLA raise.

This means if you get a 3% COLA raise and your Part B premium would normally increase by 5%, you only pay the 3% increase. The difference is covered by general Medicare funds. However, people who are new to Medicare or who did not pay Medicare taxes are not protected by hold-harmless and may see larger premium increases.

If you receive Supplemental Security Income (SSI), your federal payment limit increases with COLA. Some states add money on top of the federal amount, and those state supplements may or may not increase with COLA — it depends on state law. Contact your state SSI office to learn how your specific payment will change.

When COLA does not happen

In years when inflation is very low or when prices actually fall, there is no COLA. Your Social Security payment stays the same as the previous year. This happened most recently in 2016, when there was no raise. It also happened in 2010 and 2011.

Even in years with no COLA, your Medicare Part B premium can still increase. This creates a situation where your Social Security payment stays flat but your out-of-pocket healthcare costs go up. The hold-harmless provision still applies, but it means your actual take-home payment may shrink because more goes to Medicare.

You cannot predict whether there will be a COLA in any given year. Inflation depends on factors outside Social Security's control — energy prices, supply chains, employment, and Federal Reserve policy all play a role. Financial news outlets often speculate about the likely COLA in the fall, but the official announcement does not come until October.

What documents you need to understand your COLA raise

You do not need to submit any documents or take any action to receive your COLA raise. However, keeping records of your payment amount is useful for your own planning. Your Social Security Statement shows your payment history and current benefit amount. You can create an account at ssa.gov to view your statement online anytime.

Each December, Social Security mails a notice showing your new payment amount starting in January. Keep this notice with your tax records. If you receive SSI or other means-tested benefits, your COLA raise may affect your income limits for those programs, so you may need to report the change to the program administrator.

If you have questions about how your specific COLA raise affects your benefits, you can call Social Security at 1-800-772-1213 or visit your local Social Security office. Have your Social Security number and recent payment statement ready.

Frequently Asked Questions

Can I opt out of COLA or ask for a smaller raise?

No. COLA is automatic and applies to all beneficiaries. You cannot choose to receive a smaller raise or no raise. The amount is set by the Social Security Administration based on the CPI-W calculation.

Does COLA apply if I am still working and receiving Social Security?

Yes. If you are under full retirement age and earning income, Social Security withholds $1 from your benefit for every $2 you earn above a certain limit. However, your COLA raise still applies to your base benefit amount. Once you reach full retirement age, the earnings limit no longer applies.

How does COLA affect my taxes on Social Security?

Your COLA raise may push your combined income over the threshold where Social Security benefits become taxable. If you have other income (wages, pensions, investment earnings), a larger Social Security payment could mean more of your benefits are subject to federal income tax. Consult a tax professional about your specific situation.

What if I think the COLA calculation is wrong?

The COLA percentage is set by law based on the CPI-W index published by the Bureau of Labor Statistics. Social Security does not have discretion to change it. If you believe there is an error in how your specific payment was calculated, contact Social Security directly at 1-800-772-1213.

Does COLA apply to people receiving benefits as a spouse or survivor?

Yes. Spousal benefits, survivor benefits, and all other Social Security payments receive the same COLA percentage. The raise is applied to your benefit amount, whatever type of benefit you receive.
