What the COLA is and when it takes effect

The Cost-of-Living Adjustment (COLA) is an annual increase to Social Security benefits meant to keep pace with inflation. The Social Security Administration calculates it each year using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures price changes across food, housing, transportation, and other goods and services.

The COLA is announced in October and takes effect the following January. For example, the 2024 COLA was announced in October 2023 and went into effect in January 2024. The announcement happens on a specific date set by the Social Security Administration — typically the second Thursday in October — and you can find it on the official Social Security website.

Not all benefit amounts increase by the same dollar amount. The percentage increase applies to your current benefit, so someone receiving $2,000 per month gets a larger dollar raise than someone receiving $1,000 per month, even though both receive the same percentage increase.

Key Takeaways

  • The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers and announced each October for the following January.
  • The percentage increase varies year to year depending on inflation — some years the COLA is 0 percent, and other years it reaches 8 or 9 percent or higher.
  • Your new benefit amount appears on your Social Security statement starting in January, and direct deposits reflect the increase in the first payment of that month.
  • Supplemental Security Income (SSI) recipients also receive a COLA increase, though the rules for how it affects their benefits differ from retirement and disability beneficiaries.

How the COLA percentage is determined each year

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 risen, the percentage increase becomes that year's COLA. If prices have fallen or stayed flat, the COLA is 0 percent — benefits do not decrease.

The COLA has varied significantly over time. In recent years, the 2022 COLA was 8.7 percent, the 2023 COLA was 8.7 percent, and the 2024 COLA was 3.2 percent. These numbers reflect actual inflation in the economy during those periods. The Social Security Administration publishes historical COLA percentages on its website if you want to see what increases applied in past years.

The calculation is automatic and does not require any action from you. You do not need to contact Social Security or fill out any form to receive the increase — it happens to all beneficiaries at the same time.

When you see the increase in your payment

If you receive benefits by direct deposit, your first payment in January will include the COLA increase. The exact date depends on your birth date: the Social Security Administration pays most retirees on the second, third, or fourth Wednesday of each month based on when you were born. Your payment schedule does not change; only the amount increases.

If you receive a paper check, your January check will reflect the new amount. You should also receive a notice from Social Security in December showing your new benefit amount for the year. This notice is called the Social Security Benefit Statement, and it lists your monthly benefit, any taxes withheld, and other payment details.

You can also check your new benefit amount by logging into your Social Security account at ssa.gov. You will need to create an account using your email address and password, and then you can view your current benefit and payment history.

How the COLA affects taxes on your benefits

If your total income — including half of your Social Security benefits plus other income like wages or pensions — exceeds certain thresholds, a portion of your benefits may be subject to federal income tax. These thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. They have not changed since 1984, so as your COLA increases your benefits over time, you may cross these thresholds even if your other income stays the same.

The COLA itself does not change the tax rules, but it can push you into a higher tax bracket on your benefits. If you think this might affect you, you can adjust your federal income tax withholding by filling out a new Form W-4V and sending it to Social Security. This form tells Social Security how much federal tax to withhold from your monthly payment.

COLA rules for Supplemental Security Income (SSI) recipients

SSI is a needs-based program for people with disabilities, blindness, or age 65 and older who have limited income and resources. SSI recipients also receive a COLA increase in January, but the rules differ from retirement and disability beneficiaries.

SSI has a resource limit — the total amount of money and assets you can own and still receive benefits. For 2024, this limit is $2,000 for individuals and $3,000 for couples. The COLA increase to your SSI payment does not count against this limit in the month you receive it, but any money you save from that payment does count toward your resource limit in future months. This means you need to spend or set aside SSI payments carefully to avoid exceeding the resource limit and losing your benefits.

SSI also has an income limit. The federal SSI benefit amount for 2024 is $943 per month for individuals and $1,415 for couples, though some states add money on top of the federal amount. If your other income rises above these levels, your SSI payment decreases or stops.

What happens if you disagree with the COLA amount

You cannot dispute the COLA percentage itself — it is calculated by formula using the Consumer Price Index, and the Social Security Administration does not have discretion to change it. However, you can request that Social Security recalculate your benefit if you believe there is an error in your benefit record, such as a missing year of earnings or an incorrect wage entry.

To request a recalculation, contact Social Security by phone at 1-800-772-1213, by visiting your local Social Security office, or by creating an account at ssa.gov and sending a message through the find message system. You will need to explain what you believe is wrong and provide any documents that support your claim, such as old tax returns or W-2 forms.

Frequently Asked Questions

Can I get the COLA increase if I have not started receiving benefits yet?

No. The COLA applies only to people already receiving Social Security benefits. If you have not filed for benefits, the COLA does not affect you. When you do file, your benefit will be calculated based on your earnings record and your age at the time you file, not on past COLA increases.

Does the COLA explore to survivor benefits paid to my family members?

Yes. If your family members receive survivor benefits based on your Social Security record — such as your spouse or children — they receive the same COLA increase you do, applied to their individual benefit amounts.

What if I worked outside the United States — does the COLA still explore to my benefit?

Yes, the COLA applies to all Social Security beneficiaries regardless of where they live or worked, as long as they are receiving benefits. If you worked in another country and earned credits toward Social Security, those credits count toward your benefit calculation, and the COLA increase applies to your monthly payment.

How far in advance does Social Security announce the next year's COLA?

The announcement happens in October for the COLA that takes effect the following January. This gives you about three months' notice before the increase appears in your payment. The Social Security Administration publishes the announcement on its website and sends notices to all beneficiaries in December.
