Social Security payments rise each September based on inflation

Social Security payments increase once a year, and the announcement always comes in October for a September raise. The increase is called a Cost-of-Living Adjustment (COLA), and it is tied to inflation measured by the Consumer Price Index. If inflation has been higher over the past year, your payment goes up. If inflation has been lower or flat, the increase is smaller or zero.

The Social Security Administration calculates COLA using inflation data from July, August, and September of each year. They announce the new percentage in mid-October, and the raise takes effect the following month — in September of the next year. This means the September 2024 increase was based on inflation data from mid-2023, and the September 2025 increase will be based on inflation from mid-2024.

Not every beneficiary receives the same dollar amount increase, because COLA is a percentage. If you receive $1,500 per month and COLA is 3%, your new payment is $1,545. If you receive $3,000 per month at the same 3% COLA, your new payment is $3,090. The percentage is the same; the dollar amount depends on what you were already receiving.

Key Takeaways

  • Social Security payments increase once yearly in September by a percentage based on inflation from the previous summer.
  • The Social Security Administration announces the COLA percentage in October, roughly one month before the raise takes effect.
  • Your new payment amount depends on the COLA percentage multiplied by what you were already receiving, so higher earners see larger dollar increases.
  • You do not need to do anything to receive the increase — it is automatic for all beneficiaries, including retirees, disabled workers, and survivors.
  • Medicare premiums may increase at the same time, which can offset part or all of your Social Security raise depending on your coverage.

How the COLA percentage is calculated

The Social Security Administration uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to measure inflation. This index tracks the cost of goods and services that working people buy — food, housing, transportation, medical care, and other everyday expenses. The agency compares the average CPI-W for July, August, and September of the current year to the same three months of the previous year.

If the average is higher, there is a COLA. The percentage increase in the index becomes the percentage increase in Social Security payments. For example, if the three-month average CPI-W rises 2.5% year-over-year, all Social Security payments increase by 2.5% starting in September.

If the three-month average is the same or lower than the previous year, COLA is zero and payments do not increase. This has happened only three times since COLA began in 1975: in 2010, 2011, and 2016. In those years, beneficiaries received the same payment as the year before.

When you will see the increase in your bank account

Social Security payments are deposited on a schedule based on your birth date. Most beneficiaries receive payments on the second, third, or fourth Wednesday of each month. The September increase appears in the payment you receive in September, not in October.

If you receive your payment on the second Wednesday of September, you will see the new amount then. If your payment date is later in the month, the increase appears in that month's deposit. The Social Security Administration does not hold back the raise or phase it in — the full COLA amount is in your first September payment after the announcement.

If you have not yet started Social Security, the increase does not affect you until you begin receiving payments. Your first payment will include whatever COLA adjustments have occurred since you turned 62 (the earliest age to claim), but you will not receive back payments for years you did not collect.

Medicare premiums and how they affect your net increase

Medicare Part B premiums (which cover doctor visits and outpatient care) and Part D premiums (which cover prescription drugs) can increase at the same time Social Security does. If you are enrolled in Medicare and your premiums are deducted from your Social Security check, the net increase you see may be smaller than the COLA percentage.

For example, if your Social Security payment increases by $50 per month but your Medicare Part B premium increases by $15 per month, your actual take-home increase is $35. In some years, premium increases have been large enough to offset most or all of the COLA raise, leaving beneficiaries with little or no net gain.

The Social Security Administration has a rule called the hold-harmless provision that protects most beneficiaries: if your Medicare Part B premium increase would reduce your net Social Security payment, the government limits the premium increase so your payment does not go down. However, this protection does not apply to people who are new to Medicare or who have other income sources. Check your Social Security statement in September to see what your new payment and any premium deductions will be.

How COLA affects your lifetime benefits

The September increase compounds over time. If you receive a 3% raise one year and a 2% raise the next year, your third year's payment is 3% and 2% higher than it would have been without those increases. This means beneficiaries who live longer receive significantly more total money over their lifetime than those who claim earlier.

This is one reason financial advisors sometimes recommend delaying Social Security past age 62. If you wait until age 70 to claim, you receive a higher monthly payment (8% more per year you delay), and that higher payment is then adjusted upward by COLA each September. Over a 20-year retirement, the compounding effect of COLA on a larger base payment can add up to tens of thousands of dollars.

Conversely, if you claim at 62 and live a long time, you will receive many COLA increases on a smaller base payment. The total amount you receive over your lifetime may still be less than if you had waited, depending on how long you live and what inflation does.

What happens if you disagree with the COLA amount

You cannot dispute the COLA percentage itself — it is set by law based on the CPI-W index. However, you can verify that the increase was applied correctly to your specific payment. Check your Social Security statement online at ssa.gov or call 1-800-772-1213 to confirm your new payment amount.

If you believe there is an error in how the increase was calculated or applied to your account, you can file a request for reconsideration with your local Social Security office. Bring documentation of your current payment and the new payment amount, and explain why you believe it is incorrect. The Social Security Administration will review your account and respond in writing.

If you disagree with the COLA policy itself or believe the index used to calculate it is unfair, you can contact your elected representatives in Congress. Some advocacy groups argue that a different inflation index would better reflect the actual costs seniors face, particularly for healthcare and housing. However, changing the index would require a change to federal law.

How COLA affects other benefits tied to Social Security

Supplemental Security Income (SSI), which provides cash to low-income seniors and disabled people, also receives a COLA increase in September. The federal benefit rate for SSI increases by the same percentage as Social Security. Some states add their own money to SSI payments, and those state supplements may or may not increase at the same time.

Veterans benefits, railroad retirement benefits, and some government pensions are also adjusted for inflation, though not always on the same schedule or using the same index as Social Security. If you receive multiple benefits, check each one to see when and how it increases.

Frequently Asked Questions

When is the COLA announcement made public?

The Social Security Administration announces the COLA percentage in mid-October each year. You can find the announcement on ssa.gov, and major news outlets report it. The percentage applies to all payments beginning in September of the following year.

Do I have to do anything to get the increase?

No. The increase is automatic. You do not need to contact Social Security, file any paperwork, or take any action. The new payment amount appears in your September deposit.

Can I get the increase retroactively if I delayed claiming Social Security?

No. COLA adjustments apply only to payments you are actually receiving. If you have not claimed Social Security yet, you will not receive back payments for COLA increases from previous years. Your first payment will reflect your age and earnings record, and future payments will include COLA increases from that point forward.

What if my Medicare premium increases more than my Social Security raise?

The hold-harmless provision protects most beneficiaries from a net decrease in their Social Security payment due to Part B premium increases. However, this does not apply if you are newly enrolled in Medicare or if you have other income. Review your September statement to see your exact new payment after any deductions.

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

Yes. If you are under full retirement age and earning above the annual limit, Social Security reduces your payment, but COLA still applies to the reduced amount. Once you reach full retirement age, the earnings limit no longer applies and you receive your full payment plus the COLA increase.
