What the cost of living adjustment means for your Social Security check

Once a year, Social Security raises the monthly payment amount for most people who receive benefits. This raise is called a cost of living adjustment, or COLA. It is meant to help your benefits keep pace with inflation — the rising cost of food, housing, medicine, and other things you buy.

The adjustment is automatic. You do not have to do anything to receive it. Social Security calculates the COLA each year using a specific measure of inflation called the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The new payment amount takes effect in January, and Social Security sends a notice in December showing what your new benefit will be.

Not everyone gets a COLA every year. If inflation is flat or negative, there is no adjustment. This has happened only three times since 1975: in 2010, 2011, and 2016. Most years, however, the adjustment is positive and ranges from less than 1 percent to more than 8 percent, depending on how much prices have risen.

Key Takeaways

  • Social Security raises most benefits once per year in January based on how much inflation occurred in the previous year.
  • The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, a government measure of price changes.
  • You receive the adjustment automatically — you do not need to request it or take any action.
  • Some people, including federal employees hired after 1983 and people still working and earning above a certain threshold, may not receive the full COLA or any adjustment.
  • The December notice from Social Security shows your new payment amount before it takes effect in January.

How the COLA is calculated each year

Social Security uses the average Consumer Price Index for the third quarter of each year — July, August, and September — and compares it to the average for the same three months in the previous year. If prices have gone up, the percentage increase becomes that year's COLA. Social Security then applies this percentage to the benefit amount you received in December of the previous year.

For example, if your December benefit was $1,500 and the COLA is 3 percent, your January benefit becomes $1,545. The calculation is straightforward, but the timing matters: the COLA is based on inflation that has already happened, not inflation expected in the future. This means your raise in January reflects the cost increases you faced during the previous year.

The announcement of the COLA happens in October, when the Social Security Administration publishes the exact percentage. This gives people time to plan and allows news outlets to report the change before the new year begins. You can find the current and historical COLA percentages on the Social Security Administration website.

Who receives the COLA and who does not

Most people who receive Social Security benefits get the COLA. This includes retired workers, spouses and children of retired workers, disabled workers, and survivors of workers who have died. The adjustment applies to your entire benefit amount, not just part of it.

However, some groups receive no COLA or a reduced COLA. Federal employees who were hired before 1984 and did not pay into Social Security may not receive an adjustment. Some people who receive both a government pension and Social Security benefits may see their Social Security payment reduced by a rule called the Government Pension Offset or the Windfall Elimination Provision, which can affect how much the COLA increases their payment.

If you are still working and your earnings are above a certain threshold, Social Security may temporarily withhold part of your benefit. The COLA still applies to your full benefit amount, but the withholding amount may also increase. Once you reach full retirement age, the withholding stops and you receive your full benefit plus all future COLAs.

When the COLA takes effect and how you find out

The new COLA payment amount begins in January. Social Security sends a notice in December to everyone who receives benefits, showing the new monthly amount and explaining the change. If you have set up a my Social Security account online, you can also log in to see your updated payment information.

If you receive benefits by direct deposit, the new amount appears in your bank account on the same day each month that you normally receive your payment — usually the third, fourth, or fifth of the month, depending on your birth date. If you receive a check by mail, the timing may vary slightly.

The notice you receive in December also explains how the COLA was calculated and provides the percentage increase. Keep this notice for your records, as it documents your benefit amount for the year and can be useful if you need to verify your income for other programs or applications.

How inflation affects what your benefits can buy

The COLA is designed to maintain your purchasing power — the amount of goods and services your monthly benefit can buy. However, the COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, which may not perfectly match the inflation you actually experience.

If you spend more on healthcare, prescription drugs, or housing than the average urban wage earner, your actual cost of living may have risen faster than the COLA. Conversely, if you spend less on these items, your costs may have risen more slowly. Over time, these differences can add up, meaning the COLA may not fully protect your purchasing power in your specific situation.

Some researchers and policy advocates have proposed using a different inflation measure for Social Security beneficiaries, such as the Consumer Price Index for the Elderly (CPI-E), which tracks price changes for people aged 62 and older. This measure sometimes shows higher inflation in healthcare and housing, which are larger expenses for older adults. However, as of now, Social Security continues to use the CPI-W.

COLA and taxes on your Social Security benefits

When your benefit amount increases due to the COLA, it may affect how much of your Social Security is subject to federal income tax. Social Security benefits become taxable if your combined income — which includes your benefit, half of your Social Security, and other income like wages or investment earnings — exceeds certain thresholds.

For 2024, if you file as single and your combined income is between $25,000 and $34,000, up to 50 percent of your benefits may be taxable. If your combined income is above $34,000, up to 85 percent may be taxable. For married couples filing jointly, the thresholds are $32,000 and $44,000. These thresholds do not adjust for inflation, so as your benefit increases with the COLA, you may cross into a higher tax bracket.

This means a COLA increase can result in more of your benefit being taxed, even though the increase is meant to offset inflation. If you expect this to happen, you can adjust your federal income tax withholding by completing a new Form W-4V and submitting it to Social Security, or you can make estimated tax payments to the IRS.

Historical COLA amounts and what they tell you

The COLA has varied significantly over the decades. In the 1980s, when inflation was high, COLAs sometimes exceeded 7 percent. In the 2010s, after the financial crisis, COLAs were often below 2 percent. In 2022, the COLA was 8.7 percent, the highest in four decades, reflecting rapid inflation that year. In 2023, it was 8.7 percent again. In 2024, it was 3.2 percent.

These historical amounts show that the COLA is not fixed — it changes based on actual inflation. During periods of low inflation, your benefit may increase by less than 1 percent or not at all. During periods of high inflation, the increase can be substantial. Understanding this history can help you plan your budget and understand why your benefit amount varies from year to year.

Frequently Asked Questions

Will I get a COLA if I just started receiving benefits?

Yes, but the timing depends on when you started. If you began receiving benefits before December, you will receive the COLA in January. If you started in December, you will receive your first COLA the following January. The COLA applies to all beneficiaries regardless of when they began receiving payments.

Can I find out what my new benefit amount will be before December?

Social Security announces the COLA percentage in October, so you can calculate your new amount by multiplying your current benefit by the percentage increase. For example, if your benefit is $1,500 and the COLA is 3 percent, your new benefit will be $1,545. The official notice arrives in December, but the calculation is straightforward once the percentage is announced.

What happens to my COLA if I delay claiming Social Security?

If you have not yet claimed benefits, you do not receive a COLA because you are not receiving a payment. However, your benefit amount increases by a percentage called delayed retirement credits for each month you wait past your full retirement age, up to age 70. This is separate from the COLA and is larger than the annual adjustment.

Does the COLA apply to Supplemental Security Income (SSI)?

SSI is a different program from Social Security retirement and disability benefits. SSI does receive an annual adjustment, but it is not called a COLA. The SSI federal benefit amount increases each year based on the same inflation measure used for Social Security, so the effect is similar, but the programs are separate.

If I receive both Social Security and a pension, how does the COLA work?

The COLA applies to your Social Security benefit amount only, not to your pension. However, if you are subject to the Government Pension Offset or Windfall Elimination Provision, the way the COLA is calculated on your Social Security may be affected. You should review your December notice carefully or contact Social Security directly to understand how these rules apply to your specific situation.
