What the COLA is and when you get it

The Cost-of-Living Adjustment (COLA) is an annual increase to Social Security payments designed to keep pace with inflation. It is calculated each year based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures price changes for food, housing, energy, and other goods. If inflation rises, your benefit rises with it. If there is no inflation or prices fall, there is no COLA that year — this has happened only three times since 1975.

The COLA takes effect in January of each year. The Social Security Administration announces the percentage increase in October, so you know the new amount before it hits your account. If you receive Social Security retirement, disability (SSDI), or survivor benefits, the increase applies automatically — you do not need to do anything. Supplemental Security Income (SSI) recipients also receive a COLA, though the rules differ slightly because SSI is means-tested.

The amount of your increase depends on your current benefit amount. Someone receiving $1,500 per month gets a larger dollar increase than someone receiving $800, even though the percentage is the same. Spouses and children receiving benefits on your record also receive the same percentage increase.

Key Takeaways

  • The COLA is calculated using inflation data and announced each October for the following January.
  • Your benefit increases automatically — you do not need to contact Social Security or take any action.
  • The percentage increase is the same for all beneficiaries, but the dollar amount depends on what you currently receive.
  • In years with no inflation, there is no COLA, though this is rare.
  • The COLA affects retirement benefits, disability benefits, survivor benefits, and SSI payments.

How the COLA percentage is calculated

The Social Security Administration uses the third quarter (July, August, September) CPI-W data from the current year and compares it to the same three months from the previous year. The percentage change becomes that year's COLA. This method has been in place since 1975 and is set by federal law, so the calculation itself does not change year to year.

The CPI-W tracks prices paid by urban wage earners and clerical workers — a specific subset of the population, not all Americans. Some researchers argue this index does not reflect the actual spending patterns of older adults, who spend more on healthcare and less on transportation than the average worker. However, changing the index would require an act of Congress, and proposals to do so have not passed.

Once the October announcement is made, the percentage is final. Social Security begins paying the new amount in January. You will see the increase reflected in your bank account or check, depending on how you receive benefits.

Historical COLA amounts and what they mean for your budget

COLA increases have ranged from zero percent to over 14 percent in recent decades. In 2022, the COLA was 8.7 percent — the largest increase since 1981 — because inflation spiked that year. In 2023, it was 8.8 percent. In 2024, it was 3.2 percent. In 2025, it is 2.5 percent. These numbers vary significantly depending on inflation in any given year.

A COLA increase does not mean your purchasing power stays exactly the same. If inflation is 3 percent and your COLA is 3 percent, you are roughly even. But if inflation is higher than your COLA, you lose ground. If inflation is lower, you gain ground. The COLA is a blunt tool — it is the same for everyone, regardless of whether you spend more on medicine, rent, or food than the average beneficiary.

For planning purposes, you should not count on a specific COLA amount. Economic forecasters make predictions in the summer, but the actual number depends on inflation data released in September. If you are budgeting for the year ahead, use your current benefit amount and assume a modest increase, then adjust when the October announcement comes.

Who receives the COLA and who does not

If you receive Social Security retirement benefits, the COLA applies to you. If you receive Disability Insurance (SSDI), the COLA applies. If you receive survivor benefits as a spouse or child of a deceased worker, the COLA applies. If you receive Supplemental Security Income (SSI), the COLA also applies, though SSI has additional rules about how much you can own and earn.

Government employees who did not pay into Social Security — such as some federal workers hired before 1984 or certain state and local employees — may receive a different benefit structure and may not receive a COLA on their government pension. However, if they also receive Social Security benefits based on other work, those benefits do receive the COLA.

If you are still working and have not yet claimed Social Security, the COLA does not affect you yet. Once you claim, future COLAs will increase your benefit. The COLA is applied to your Primary Insurance Amount (the benefit you are may have access to to at your full retirement age), so it affects your benefit for life.

How the COLA interacts with taxes and means-tested programs

A COLA increase can push some of your Social Security income into taxable territory. If your combined income (adjusted gross income plus half your Social Security benefits) exceeds certain thresholds — $25,000 for single filers or $32,000 for married couples filing jointly — up to 50 percent of your benefits become taxable. If your combined income exceeds higher thresholds ($34,000 for single filers or $44,000 for married couples), up to 85 percent becomes taxable. A COLA increase can move you across these thresholds.

For SSI recipients, a COLA increase can affect your may be able to access if you are close to the resource or income limits. SSI has strict limits on how much you can own ($2,000 for individuals, $3,000 for couples as of 2024, though these amounts adjust annually). A COLA increase to your SSI benefit does not count against this limit, but other income or resources do. If you receive both SSI and Social Security, the COLA increase to your Social Security benefit may reduce your SSI payment dollar-for-dollar.

If you receive Medicaid or other means-tested benefits, check with your state program to understand how a COLA increase affects your case. Rules vary by state and program.

What happens if you disagree with the COLA calculation

The COLA is set by law and calculated by a fixed formula. You cannot dispute the percentage itself — it is the same for everyone. However, you can verify that Social Security applied the correct percentage to your specific benefit amount. If you believe your January payment is wrong, contact Social Security directly.

You can reach Social Security by phone at 1-800-772-1213 (TTY 1-800-325-0778), by visiting your local Social Security office, or by creating an account at ssa.gov. Have your Social Security number and your benefit statement ready. Social Security staff can compare your old and new benefit amounts and explain the calculation.

If you find an error — for example, if Social Security applied last year's COLA instead of this year's — you can request a correction. Social Security has procedures for addressing payment errors, though the process can take several weeks.

Planning ahead with COLA information

You can use the announced COLA to update your annual budget. If you receive $2,000 per month and the COLA is 2.5 percent, your new benefit will be approximately $2,050. This is useful for planning healthcare costs, housing expenses, and other fixed bills.

If you are still working and deciding when to claim Social Security, remember that delaying your claim increases your benefit by about 8 percent per year until age 70. A higher starting benefit means a higher base for future COLAs. For example, if you claim at 62 instead of 67, your benefit is lower, and all future COLAs are calculated on that lower amount.

If you have questions about how the COLA affects your specific situation — for instance, if you also receive a pension or are still working — Social Security's website has benefit calculators and detailed explanations. You can also speak with a Social Security representative at your local office.

Frequently Asked Questions

When is the COLA announced and when does it take effect?

The Social Security Administration announces the COLA in October each year. It takes effect in January. For example, the 2025 COLA of 2.5 percent was announced in October 2024 and began in January 2025. You will see the new amount in your first payment of the year.

Can I opt out of the COLA increase?

No. The COLA is applied automatically to all may be able to access beneficiaries. You cannot choose to keep your old benefit amount. However, you can contact Social Security if you believe the increase was calculated incorrectly for your specific case.

Does the COLA apply if I am still working?

If you are receiving Social Security benefits and still working, the COLA still applies to your benefit. However, if your earnings exceed the annual limit, Social Security will withhold part of your benefit. The COLA increases your benefit amount, but the earnings limit may still result in withholding. Once you reach full retirement age, the earnings limit no longer applies.

How does the COLA affect my Medicare premiums?

Social Security has a "hold harmless" rule that protects most beneficiaries: your Medicare Part B premium cannot increase more than your COLA increase. If your COLA is 2.5 percent but Medicare premiums rise 3 percent, you pay the lower increase and the difference is covered by general Medicare funds. However, new Medicare beneficiaries and higher-income beneficiaries may not receive this protection.

What if inflation is negative — will my benefit decrease?

No. Social Security law does not allow benefits to decrease due to a negative COLA. If inflation falls and the CPI-W declines, there is simply no COLA that year — your benefit stays the same. This has happened only three times since 1975, most recently in 2010 and 2011.
