What the SSDI inflation adjustment is and when it happens

Every January, Social Security Disability Insurance (SSDI) payments increase by a percentage set by the federal government. This increase is called a Cost-of-Living Adjustment (COLA), and it is meant to keep your monthly payment from losing value as prices rise. The amount of the increase changes each year depending on how much inflation happened in the previous months.

The Social Security Administration announces the COLA percentage in October for the following January. For example, in October 2023, the SSA announced a 3.2% increase that took effect in January 2024. You do not have to do anything to receive this increase — it happens automatically to your account.

The COLA applies to your full monthly SSDI payment amount. If you receive $1,200 per month and the COLA is 3.2%, your new payment becomes $1,238.40 starting in January.

Key Takeaways

  • SSDI payments increase automatically each January by a percentage called the Cost-of-Living Adjustment (COLA), which the Social Security Administration announces in October.
  • The COLA percentage varies year to year based on inflation data from the previous months and is the same for all SSDI recipients.
  • You will see the new payment amount on your Social Security statement in December or early January, and the increase deposits with your regular payment in January.
  • If you also receive Supplemental Security Income (SSI), that program has a separate COLA that may differ from SSDI.

How the COLA percentage is calculated

The Social Security Administration uses inflation data from the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to set the COLA. Specifically, they compare the average CPI-W for July, August, and September of the current year to the same three months from the previous year. If there is no increase, the COLA is 0% — payments do not decrease.

This means the COLA you receive in January 2025 is based on inflation that happened between mid-2023 and mid-2024. The lag between when inflation occurs and when your payment adjusts is built into the system.

Congress does not vote on the COLA each year. The increase is automatic and calculated by a formula written into Social Security law. The only exception is if Congress passes a law to change how the COLA is calculated, which happens rarely.

When you will see the increase in your payment

The Social Security Administration mails a notice to your address on file in December, before the January payment increase. This notice shows your new monthly payment amount and the COLA percentage. If you have a my Social Security account online, you can also view the new amount there starting in late December.

The increased payment deposits into your bank account or arrives by check on your regular payment date in January. Most SSDI recipients receive payments on the third of the month, though the exact date depends on your birth date. If January 3rd falls on a weekend or holiday, the payment arrives on the business day before.

If you do not receive a notice by mid-January, contact the Social Security Administration at 1-800-772-1213 to confirm the increase was applied to your account.

COLA history and what payments looked like in past years

The COLA has varied significantly over the past decade. From 2009 to 2020, many years had very small increases — some years were 0%. In 2021 and 2022, the COLA was 1.3% and 5.9%. In 2023, it jumped to 8.7%, the highest in 40 years. In 2024, it was 3.2%.

To see what your payment was in a previous year, you can request a Social Security earnings record or benefit statement from your my Social Security account. This shows your payment history month by month. You can also call 1-800-772-1213 and ask a representative to read your payment history over the phone.

The COLA does not make up for years when inflation was high but the COLA was low. It only adjusts your current payment forward from that point. If you received a 0% COLA in 2010 but inflation was 1.6%, that lost purchasing power does not get added back later.

How COLA affects your work incentives and other benefits

If you are using SSDI work incentives — programs that let you work and still receive some or all of your SSDI payment — the COLA increase applies to your payment just as it does for anyone else. Your work incentive rules do not change because of the COLA.

If you also receive Supplemental Security Income (SSI), that program has its own separate COLA. The SSI COLA is often the same percentage as SSDI, but not always. The SSA will notify you of both increases if you receive both programs.

If you are receiving SSDI and your family members receive benefits on your record (such as a spouse or child), they also receive the same COLA percentage increase on their payments.

What to do if you think the COLA was not applied correctly

Compare your December notice to your January payment. The new payment should match the amount shown in the notice. If it does not, or if you did not receive a notice, contact the Social Security Administration when ready.

Call 1-800-772-1213 (TTY 1-800-325-0778) Monday through Friday, 7 a.m. to 7 p.m. Eastern Time. Have your Social Security number ready. A representative can tell you what COLA percentage was applied and confirm the new payment amount in your account.

You can also visit a local Social Security office in person. Find the office nearest you at ssa.gov/locator. Bring your Social Security card and a photo ID.

Frequently Asked Questions

Can I get a COLA increase if I just started receiving SSDI?

Yes. If you start receiving SSDI before January, you will receive the COLA increase in your first January payment. The increase applies to all SSDI recipients, regardless of when they began receiving payments.

What if I disagree with the COLA percentage the SSA announced?

The COLA is set by law based on the Consumer Price Index. You cannot dispute the percentage itself. If you believe the SSA made an error in calculating your individual payment, you can contact them to review your account, but the COLA percentage is the same for all recipients.

Does the COLA increase affect my Medicare premiums?

SSDI recipients do not pay Medicare premiums directly from their SSDI payment. However, if you also receive Social Security retirement benefits, a COLA increase can affect your Medicare Part B premium. The SSA will notify you of any premium changes.

Will the COLA ever decrease my payment?

No. If inflation is negative (deflation), the COLA is 0% and your payment stays the same. Your payment will never go down because of a COLA calculation. Congress would have to pass a new law to reduce SSDI payments, which has not happened.

How do I know what next year's COLA will be?

The Social Security Administration announces the COLA for the following year in October. You can find the announcement on ssa.gov or call 1-800-772-1213 to ask. The COLA is based on inflation data from July, August, and September, so it cannot be predicted with certainty until October.
