The 2026 COLA will increase SSDI payments, but the exact amount won't be announced until October 2025

Social Security announces the annual cost of living adjustment (COLA) in October of each year, and that announcement sets the percentage increase for all SSDI payments the following January. For 2026, the adjustment has not yet been calculated because it depends on inflation data collected through September 2025. When October arrives, the Social Security Administration will publish the 2026 COLA percentage, and your benefit amount will rise by that same percentage on your January 2026 payment.

The COLA is not a choice or something you explore for—it happens automatically. If you receive SSDI in December 2025, your January 2026 payment will be larger by the COLA percentage. The only exception is if you have not yet reached your full retirement age and you are working; in that case, your benefit may be reduced by the earnings test, which operates separately from COLA.

Because the 2026 COLA has not been calculated, any specific dollar figure you see online is a projection or estimate, not the real number. Projections exist, but they change as new inflation data arrives. The actual figure will be official only after October 2025.

Key Takeaways

  • The 2026 COLA percentage will be announced in October 2025 and will take effect on January 2026 payments.
  • COLA is automatic—you do not need to do anything to receive the increase, and it applies to all SSDI beneficiaries at the same rate.
  • The adjustment is based on inflation measured through September 2025, so the exact percentage depends on economic data not yet collected.
  • If you are working and under full retirement age, the earnings test may still reduce your benefit even after the COLA increase.

How the COLA is calculated and why it changes year to year

The COLA is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a measure of inflation published by the Bureau of Labor Statistics. Social Security compares the average CPI-W for July, August, and September of the current year to the same three months of the previous year. If inflation has occurred, the percentage increase becomes the COLA. If there is no inflation or prices have fallen, the COLA is zero (benefits do not decrease).

This means the COLA reflects what actually happened to prices in the months leading up to the announcement. A year with high inflation produces a higher COLA; a year with low inflation produces a lower one. The 2025 COLA, announced in October 2024, was 3.2 percent because inflation during summer 2024 was 3.2 percent higher than summer 2023. The 2026 COLA will depend entirely on what inflation looks like in summer 2025.

Because inflation is unpredictable, projections of the 2026 COLA vary. Some economists and policy organizations publish estimates based on current economic conditions, but these are guesses, not guarantees. The only official number comes from Social Security in October 2025.

What happens to your benefit amount in January 2026

On your first payment in January 2026, your monthly SSDI amount will increase by the 2026 COLA percentage. If your current benefit is $1,200 per month and the COLA is 2.5 percent, your new benefit will be $1,230 per month. The increase is permanent unless Congress changes the law or your work earnings trigger a reduction under the earnings test.

The increase applies to your primary insurance amount, which is the base benefit calculated from your work history. If you receive a family benefit (as a spouse or child of a worker), your family benefit also increases by the same percentage. If you are on the Supplemental Security Income (SSI) program instead of SSDI, you receive a separate COLA that is also announced in October but may differ slightly from the SSDI COLA.

You will see the new amount on your Social Security statement or in your online account at ssa.gov. If you receive your payment by direct deposit, the larger amount will appear in your bank account on your regular payment date in January. If you have questions about the amount, you can contact Social Security at 1-800-772-1213.

How COLA affects Medicare premiums and other deductions

When your SSDI benefit increases due to COLA, your Medicare Part B premium may also change. Social Security uses a hold-harmless provision that protects most beneficiaries: if your Medicare Part B premium increases, the increase cannot be larger than your COLA increase. This means your net benefit (what you actually receive after Medicare is deducted) will not go down.

However, if you are a higher-income beneficiary or you enrolled in Medicare Part B after age 65, you may pay an income-related premium adjustment that is not protected by hold-harmless. These beneficiaries may see their Medicare costs rise faster than their COLA increase. If you are unsure whether hold-harmless applies to you, you can ask Social Security or Medicare directly.

Other deductions—such as overpayment repayment, child support, or taxes withheld—are not affected by COLA. If Social Security is withholding money from your benefit for any reason, that withholding continues at the same rate, and your net payment increases by less than the full COLA percentage.

COLA and the earnings test for people who work

If you are under full retirement age and you work, the earnings test may reduce your SSDI benefit regardless of COLA. The earnings test does not change with COLA; it is a separate rule. In 2025, Social Security reduces your benefit by $1 for every $2 you earn above $23,400 per year. This limit may increase in 2026, but the increase is based on wage growth, not the SSDI COLA.

The COLA increases your benefit amount, but the earnings test is applied to that new amount. If your earnings are high enough to trigger a reduction, the reduction is calculated on your new, higher benefit. For example, if your new 2026 benefit is $1,230 and you earn $30,000, the earnings test reduces your benefit by a portion of that $1,230, not your old amount.

Once you reach full retirement age, the earnings test no longer applies, and you receive your full benefit plus any COLA increases, with no reduction for work.

Planning ahead: what to expect and what to do now

You do not need to do anything to receive the 2026 COLA. The increase is automatic and will appear in your January payment. However, you can prepare by understanding how the increase might affect your budget, your taxes, or your other benefits.

If you are working and close to the earnings limit, the COLA increase means your benefit will be higher, which may affect how much you can earn before the earnings test applies. If you are receiving Medicaid or other means-tested benefits, the COLA increase might affect your income level for those programs. Some states count SSDI income differently, so contact your state Medicaid office if you are unsure.

If you want to see a projection of the 2026 COLA before October, you can check the Social Security Office of the Chief Actuary website or news articles from policy organizations, but remember these are estimates. The official announcement will come in October 2025, and your actual new benefit will be clear when you receive your January 2026 payment.

Frequently Asked Questions

When will I know the exact 2026 COLA percentage?

Social Security will announce the 2026 COLA in October 2025. The announcement is made public on the Social Security website and through news outlets. You do not need to check—Social Security will automatically explore the increase to your January 2026 payment.

Will the COLA increase affect my Medicaid or SSI benefits?

SSDI and SSI are separate programs with separate COLAs. If you receive SSI, you will receive a separate SSI COLA announcement in October. If you receive Medicaid, the COLA increase to your SSDI may affect your income level for Medicaid purposes, depending on your state's rules. Contact your state Medicaid office to confirm.

What if I disagree with the COLA amount or think there's an error?

The COLA is set by law and applies to all beneficiaries equally—there is no individual disagreement process. If you believe your specific benefit amount is wrong, you can contact Social Security at 1-800-772-1213 to review your payment history and work record.

Does COLA explore if I'm receiving benefits as a family member of a worker?

Yes. If you receive a benefit as a spouse, ex-spouse, or child of an SSDI worker, your benefit also increases by the 2026 COLA percentage. The increase applies to all family members on the same worker's record.

Can I opt out of the COLA increase?

No. COLA is automatic and applies to all SSDI beneficiaries. You cannot choose to keep your old benefit amount or defer the increase.
