The 2026 COLA will be announced in October 2025, and it will increase most retirement checks starting in January 2026

The Cost of Living Adjustment (COLA) is an annual percentage increase to Social Security payments meant to keep up with inflation. The Social Security Administration calculates it each year using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), measured from July through September. In October, they announce the percentage, and the raise takes effect the following January for people already receiving benefits.

For 2026, the exact COLA percentage will not be known until October 2025, when the SSA releases the official figure. The adjustment applies to retirement benefits, survivor benefits, and disability benefits. If you receive Social Security, your January 2026 payment will reflect this increase — you do not need to do anything to receive it.

The COLA has varied significantly year to year. In 2024 it was 3.2 percent. In 2025 it is 3.2 percent. These numbers depend entirely on inflation data from the summer months, which the government cannot predict in advance.

Key Takeaways

  • The 2026 COLA percentage will be announced in October 2025 and will take effect on January 1, 2026.
  • COLA is calculated using inflation data from July through September and is the same percentage for all beneficiaries.
  • Your January 2026 payment will automatically include the COLA increase; you do not need to report anything or take action.
  • The exact amount your check increases depends on your current benefit amount — a higher current payment means a larger dollar increase.
  • People who have not yet claimed Social Security will receive the COLA automatically when they start benefits after January 2026.

How the COLA is calculated and why it changes each year

The Social Security Administration uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to measure inflation. 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 prices have risen, the percentage increase becomes the COLA.

The COLA changes year to year because inflation itself changes. When inflation is high, the COLA is higher. When inflation is low or prices are stable, the COLA is lower. There is no minimum COLA — in years when inflation is negative (deflation), the COLA can be zero, meaning no increase. This has happened only three times since 1975: in 2010, 2011, and 2016.

The CPI-W measures prices for food, housing, transportation, medical care, and other goods and services that urban workers typically buy. It does not measure prices that affect only rural workers or only retirees, so some people argue it does not perfectly reflect the actual cost increases that Social Security beneficiaries face. However, Congress has not changed the formula.

What the 2026 COLA means for your monthly check

If you receive Social Security retirement benefits in 2025, your January 2026 payment will be higher by the 2026 COLA percentage. The actual dollar amount depends on your current benefit. Someone receiving $1,500 per month will see a smaller dollar increase than someone receiving $3,500 per month, even though the percentage is the same.

For example, if the 2026 COLA is 2.5 percent, a person receiving $1,500 would see their check increase by about $37.50 per month. A person receiving $3,500 would see an increase of about $87.50 per month. These are illustrations only — your actual increase will depend on the real COLA announced in October 2025.

The COLA also affects your Medicare Part B premium if you pay one. Some beneficiaries are protected by a "hold harmless" rule, which means their Social Security check cannot go down even if Medicare premiums rise. Others may see their net increase reduced if Medicare premiums increase faster than the COLA.

When you will see the 2026 COLA on your payment

If you receive Social Security by direct deposit, the increased payment will arrive in your bank account on your regular payment date in January 2026. If you receive a paper check, it will arrive by mail. You do not need to contact Social Security or take any action — the increase is automatic.

People who claim Social Security for the first time after January 1, 2026, will receive the 2026 COLA built into their initial benefit amount. They will not receive a separate notice about it.

The Social Security Administration sends a notice called the Social Security Statement to beneficiaries each year, usually in December. This notice will show your new benefit amount for January 2026 and explain the COLA increase.

How COLA affects your lifetime benefits and future increases

The COLA is compounding — each year's increase becomes the base for the next year's calculation. If you receive Social Security for 20 years, you will receive 20 separate COLA increases (or zero increases in years when there is no COLA). Over a long retirement, these add up significantly.

The COLA also affects your spouse's or survivor's benefits if you are receiving them. A spouse receiving 50 percent of your benefit will receive 50 percent of the COLA increase you receive. A child or widow receiving survivor benefits will receive the same COLA percentage as you would have.

If you delay claiming Social Security past your full retirement age, your benefit grows by 8 percent per year until age 70. This growth is separate from the COLA. Once you claim, both the delayed retirement credits and the COLA apply to your benefit going forward.

Planning for the 2026 COLA when you have not yet claimed

If you have not yet claimed Social Security, the 2026 COLA will affect the benefit amount you receive when you do claim. The SSA recalculates your Primary Insurance Amount (PIA) — the base benefit used to determine what you receive — each year to account for wage growth and COLA. The exact benefit you receive depends on when you claim and what your earnings record shows.

Claiming at 62 gives you a smaller monthly payment than claiming at 67 or 70, but the COLA applies to whatever amount you receive. Someone who claims at 62 in 2026 will receive a lower monthly payment than someone who claims at 67 in 2026, but both will have the 2026 COLA built into their initial benefit.

If you are deciding when to claim, the COLA is one factor among several. A financial advisor or the Social Security Administration's website can help you model different claiming ages and see how COLA affects your lifetime benefits under different scenarios.

Frequently Asked Questions

Will the 2026 COLA be higher or lower than 2025?

No one knows until October 2025, when the SSA announces it. The COLA depends on inflation data from July through September 2025. If inflation is higher than it was in the same months in 2024, the COLA will be higher. If inflation is lower, the COLA will be lower.

Do I have to do anything to receive the 2026 COLA increase?

No. If you receive Social Security, the increase is automatic and will appear in your January 2026 payment. You do not need to contact Social Security, file a form, or take any action.

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

SSI recipients receive a separate COLA that is announced at the same time as the Social Security COLA, but it is calculated differently and may be a different percentage. Check your SSI notice in December 2025 for your specific increase.

What if I am still working and receiving Social Security in 2026?

The COLA applies to your benefit regardless of whether you are working. However, if you are under full retirement age and earn above the earnings limit, Social Security will withhold $1 for every $2 you earn above the limit. The COLA increases your benefit amount, but the earnings test still applies.

Can the COLA ever be zero or negative?

Yes. If inflation is zero or negative, there is no COLA increase that year. This happened in 2010, 2011, and 2016. It is rare but possible.
