What COLA is and why Social Security payments change each year

COLA stands for Cost-of-Living Adjustment. It is an annual increase to Social Security payments meant to keep up with inflation — the rising cost of food, housing, medicine, and other necessities. Without COLA, the same monthly check would buy less each year as prices climb.

The Social Security Administration calculates COLA once per year using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a measure of inflation published by the Bureau of Labor Statistics. The percentage increase in the CPI-W from the third quarter of one year to the third quarter of the next becomes that year's COLA percentage. If inflation was flat or negative, COLA can be zero or does not happen.

COLA applies to all Social Security benefits — retirement, survivor, and disability payments — and also to Supplemental Security Income (SSI). It takes effect in January of each year. The Social Security Administration announces the COLA percentage in October, so you know the new amount before your January payment arrives.

Key Takeaways

  • COLA is calculated from inflation data released by the Bureau of Labor Statistics and announced by Social Security each October for the following January.
  • The COLA percentage applies to all types of Social Security benefits and to SSI payments equally.
  • COLA can be zero in years when inflation is flat or negative, meaning no increase that year.
  • You do not need to do anything to receive your COLA increase — it happens automatically to your account.
  • Your new payment amount appears in your January benefit statement or online account, and the first adjusted payment arrives in January.

How the COLA percentage is calculated each year

The Social Security Administration does not choose the COLA percentage. Instead, it is set by law to match the change in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from July, August, and September of one year compared to the same three months of the previous year.

The Bureau of Labor Statistics publishes the CPI-W monthly. Social Security uses the average of the three summer months to smooth out any single month that was unusually high or low. If that average is higher than the previous year's average, the difference becomes the COLA percentage. If the average is the same or lower, COLA is zero — there is no negative COLA that reduces payments.

This means COLA reflects what actually happened to prices in the recent past, not a prediction of future inflation. A year with high inflation in the summer months will produce a high COLA announced in October. A year with low inflation will produce a low COLA or zero COLA.

When you receive your COLA increase and how to verify the amount

Your COLA increase takes effect on January 1 each year. If you receive Social Security by direct deposit, the new amount appears in your bank account with your January payment. If you receive a check by mail, the January check reflects the new amount.

You can see your new payment amount before January arrives. The Social Security Administration mails a notice called the "Social Security Benefit Statement" to all beneficiaries in December, showing the new monthly amount starting in January. You can also view your payment amount online through your my Social Security account at ssa.gov. Log in, select "Benefit Verification Letter" or "Payment History," and the current and upcoming amounts are listed there.

If you notice the January amount is not what the December statement said, contact Social Security at 1-800-772-1213 to report the discrepancy. Keep your December statement for reference.

COLA in years with high inflation versus low inflation

COLA varies significantly from year to year depending on inflation. In recent history, COLA has ranged from zero (in 2010 and 2011, when inflation was very low) to 8.7 percent (in 2023, when inflation was high). The amount you receive depends entirely on what the CPI-W showed during the measurement period.

In years with high inflation, COLA is larger and your payment increases noticeably. In years with low inflation, COLA is small or zero. This means your purchasing power — what your check can actually buy — stays roughly the same over time, though it will not keep pace perfectly if inflation is uneven across different types of goods and services.

COLA does not make up for past years when inflation outpaced the increase. If inflation was high one year and low the next, your payment reflects only the current year's adjustment, not a catch-up for the previous year's shortfall.

How COLA affects different types of Social Security recipients

COLA applies the same percentage increase to all Social Security beneficiaries — whether you receive retirement benefits, survivor benefits, or disability benefits (SSDI). A 3 percent COLA means a 3 percent increase for everyone, regardless of the type of benefit or the amount you currently receive.

Family members receiving benefits on your record also receive the same COLA percentage. If your spouse or children receive benefits based on your work history, their payments increase by the same percentage as yours in January.

Supplemental Security Income (SSI) recipients also receive COLA, though SSI is a separate program from Social Security. The COLA percentage is the same, but SSI has different rules about how much you can earn and own before benefits are reduced.

What happens if you have not started Social Security yet

If you have not begun receiving Social Security, COLA does not affect you directly yet. However, the benefit amount you will receive when you do start is calculated using your lifetime earnings record, adjusted for inflation through the year you turn 60. This adjustment is separate from COLA and uses a different inflation measure (the National Average Wage Index).

Once you start receiving benefits, COLA applies to your payment from that point forward. Starting benefits later (after your full retirement age, up to age 70) increases your monthly amount permanently, and that higher amount then receives COLA each year.

Common questions about COLA and your payment

Some people wonder whether COLA is taxable income. The answer depends on your total income. If Social Security is your only income, the COLA increase is not taxable. If you have other income (wages, pensions, investment income), part of your Social Security benefits, including the COLA increase, may be subject to federal income tax. Your Social Security statement shows the amount subject to tax.

Others ask whether COLA is the same for everyone. It is — the percentage is uniform across all beneficiaries. However, the dollar amount of the increase varies because it is a percentage of your current payment. Someone receiving $2,000 per month gets a larger dollar increase from a 3 percent COLA than someone receiving $1,000 per month, even though the percentage is identical.

Frequently Asked Questions

When is COLA announced and when does it take effect?

Social Security announces the COLA percentage in October each year. The increase takes effect on January 1 of the following year. Your first payment at the new amount arrives in January, and you receive a notice in December showing the new monthly amount.

Can COLA be negative or reduce my payment?

No. COLA is never negative. If inflation is flat or negative, COLA is zero and your payment stays the same. Your payment will not decrease due to COLA.

Do I need to do anything to receive my COLA increase?

No. COLA is applied automatically to your account. You do not need to contact Social Security, file any form, or take any action. The increase appears in your January payment.

How do I find out what my new payment will be?

Check your December Social Security Benefit Statement, which shows your new monthly amount starting in January. You can also log into your my Social Security account at ssa.gov and view your payment history and current benefit amount.

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

Yes. COLA applies to all beneficiaries regardless of whether you are working. However, if you are under full retirement age and earn above a certain amount, part of your benefit may be withheld. COLA increases your benefit amount, but the earnings limit and withholding rules remain the same.
