Social Security payments go up once a year based on inflation, a raise called the Cost of Living Adjustment or COLA

Every October, the Social Security Administration announces a percentage increase that applies to all benefit payments starting the following January. This raise is tied to the Consumer Price Index, which measures how much prices for everyday goods and services have risen over the past year. If inflation was high, the COLA is higher. If inflation was low or prices fell, the COLA can be very small or zero.

You do not have to do anything to receive the raise — it happens automatically. The new payment amount appears in your January benefit, and your Medicare premiums (if you pay them) are adjusted at the same time. The raise applies to retirement benefits, survivor benefits, and disability benefits equally.

Key Takeaways

  • The COLA is announced each October and takes effect in January, based on inflation data from the previous 12 months.
  • The percentage varies year to year and can be zero if prices did not rise; it has ranged from 0% to over 8% in recent decades.
  • You receive the raise automatically with no action required on your part.
  • Your Medicare Part B and Part D premiums may increase at the same time, which can offset part of your benefit raise.

How the COLA is calculated and announced

The Social Security Administration uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to set the COLA. This index tracks price changes for food, housing, transportation, medical care, and other expenses that working people spend money on. The agency compares the average CPI-W for July, August, and September of the current year to the same three months from the previous year. That percentage increase becomes the COLA for the following year.

The announcement happens in mid-October each year. You can find the exact percentage on the Social Security Administration website, or your Social Security statement will show your new payment amount when it updates in December. The raise takes effect with your January payment.

What the COLA has been in recent years

COLA amounts have varied significantly depending on inflation. In 2024, the COLA was 3.2%. In 2023, it was 8.7%, the largest increase in four decades. In 2022, it was 5.9%. In 2021, it was 1.3%. In 2020, it was 1.3%. In 2019, it was 2.8%. During the years 2010 through 2020, there were three years with 0% COLA because inflation was flat or negative.

The COLA protects your purchasing power over time, but it does not always keep pace with the actual costs retirees face. Medical expenses, for example, often rise faster than the general inflation rate that the CPI-W measures. This means your benefit may not stretch as far for healthcare as it did in previous years, even with the annual raise.

How the COLA affects your Medicare premiums

Your Medicare Part B premium (which covers doctor visits and outpatient care) and your Part D premium (which covers prescription drugs) are usually adjusted at the same time your Social Security benefit increases. In some years, the premium increase is small enough that your net benefit raise is substantial. In other years, especially when medical costs rise sharply, the premium increase can consume most or all of your COLA.

There is a rule called "hold harmless" that protects most people: your Medicare Part B premium cannot increase by more than the amount of your Social Security COLA. This means your net Social Security payment will not go down because of a premium increase. However, this protection does not apply to people who are newly enrolled in Medicare or who did not receive Social Security in the previous year.

When you might not receive the full COLA

If you are still working and earning above a certain threshold, part of your Social Security benefit may be withheld. The earnings limit and the withholding rate change each year, and they are separate from the COLA. The COLA still applies to your benefit amount, but you may not receive all of it if you are working.

If you owe money to the federal government — such as unpaid taxes or a defaulted federal student loan — your Social Security payment can be reduced to pay that debt. The COLA increases your benefit, but the offset may still apply to the new amount. Similarly, if you owe child support or alimony, those obligations can reduce your payment.

Planning around the COLA and inflation

The COLA is meant to help you keep up with inflation, but it is calculated on a national average. Your actual cost of living may be higher or lower depending on where you live and what you spend money on. If you live in an area with high housing costs or if your medical expenses are above average, the COLA may not fully cover your increased costs.

When you are planning your retirement budget, assume that the COLA will vary from year to year and may sometimes be zero. Do not count on a specific percentage increase. If you have savings or other income sources, they can help bridge the gap in years when inflation is high but the COLA has not yet taken effect, or when your actual expenses rise faster than the national average.

Frequently Asked Questions

Can I get a COLA raise if I just started receiving Social Security?

Yes. You receive your first COLA in the January after you have been on the rolls for a full calendar year. If you start receiving benefits in June, you will get your first COLA the following January, even though you have only been receiving for seven months.

What if I disagree with the COLA amount announced?

The COLA is set by law based on the Consumer Price Index. You cannot dispute the percentage itself. However, you can contact Social Security to verify that your benefit was calculated correctly and that the COLA was applied to your account.

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

SSI recipients receive a separate annual raise called the Federal Benefit Rate increase, which is also based on inflation and takes effect in January. The percentage may differ slightly from the Social Security COLA because SSI uses a different calculation method.

Will the COLA keep up with my actual expenses?

The COLA is based on average inflation across the country. If your costs rise faster than the national average — especially for healthcare or housing — the COLA may not fully cover your increased expenses. This is why having additional savings or income sources is important in retirement.
