The 2026 COLA will depend on inflation data released in September 2025

The Social Security cost-of-living adjustment (COLA) for 2026 has not been announced yet because it is based on inflation numbers that won't be final until September 2025. The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures how prices change across the economy. The Social Security Administration compares the average CPI-W for July, August, and September of one year to the same three months of the previous year. If prices went up, beneficiaries get a raise. If prices stayed flat or fell, there is no COLA that year.

The 2025 COLA was 3.2 percent, which means someone receiving $1,000 per month in December 2024 received about $1,032 per month starting in January 2025. The 2026 COLA will be different because it depends entirely on what happens to prices between now and September 2025. No one can predict it with certainty, though economists and news outlets sometimes publish estimates based on inflation trends.

Key Takeaways

  • The 2026 COLA will be announced in October 2025 and takes effect in January 2026, based on inflation data from July through September 2025.
  • COLA is calculated by comparing average prices in the third quarter of 2025 to the same period in 2024, using the Consumer Price Index for Urban Wage Earners and Clerical Workers.
  • If inflation is higher than it was in mid-2024, the COLA will be higher; if inflation is lower, the COLA will be lower.
  • The Social Security Administration does not estimate or predict the COLA in advance — only actual inflation data determines the final number.
  • You will receive notice of your 2026 COLA amount in a letter from Social Security, usually arriving in December 2025.

How the COLA calculation actually works

The Social Security Administration uses a specific three-month window to measure inflation: July, August, and September. They calculate the average CPI-W for those three months in 2025 and compare it to the average for July, August, and September 2024. The percentage increase (or decrease) becomes the COLA.

For example, if the average CPI-W for July-September 2024 was 320 and the average for July-September 2025 is 329.6, the increase is 3 percent. Every Social Security beneficiary would receive a 3 percent raise on their January 2026 payment. This same calculation method has been used since 1975, so it is consistent from year to year.

The CPI-W is published monthly by the Bureau of Labor Statistics, a division of the U.S. Department of Labor. You can see the actual numbers on the Bureau of Labor Statistics website if you want to track inflation yourself. The Social Security Administration does not adjust or round the COLA — they use the exact percentage that the data produces.

Why inflation in mid-2024 matters for the 2026 COLA

The 2026 COLA compares prices in summer and fall 2025 to prices in summer and fall 2024. This means inflation that happened in early 2024 or late 2024 does not directly affect the 2026 number. The comparison period is fixed and narrow by design, so the COLA reflects recent price changes rather than the entire year.

In mid-2024, inflation was running lower than it had been in 2023. If inflation stays at similar levels through September 2025, the 2026 COLA will be modest. If prices rise sharply between now and September 2025, the COLA will be higher. If prices fall or stay completely flat, there could be no COLA at all, though this is rare.

When you will find out the 2026 COLA amount

The Social Security Administration announces the COLA in October of the year before it takes effect. For 2026, the announcement will happen in October 2025. You will receive an official notice in the mail, usually in December 2025, showing your new benefit amount starting in January 2026.

If you receive your benefits by direct deposit, the new amount will appear in your bank account on the third day of January 2026 (or the next business day if January 3 falls on a weekend). If you receive a check, it will be mailed according to your payment schedule, which depends on your birth date.

What you cannot do about the COLA

You cannot request a higher COLA or negotiate your raise. The COLA is determined by inflation data, not by individual circumstances. Social Security does not consider your expenses, your health costs, or how much money you have saved. The same percentage applies to every beneficiary, whether you receive $500 per month or $3,000 per month.

You also cannot delay or accelerate your COLA. It takes effect automatically in January of the year it applies to. If you are still working and your earnings affect your benefit (because you have not yet reached full retirement age), the COLA still applies, but your benefit may be reduced by your work earnings that year.

How COLA affects different types of Social Security payments

The COLA applies to retirement benefits, survivor benefits (paid to family members of a deceased worker), and disability benefits. If you receive Supplemental Security Income (SSI), a separate needs-based program, you receive a different COLA calculation that is announced at the same time but may be a different percentage.

Spouse and child benefits are tied to the worker's benefit amount, so they receive the same COLA percentage as the primary beneficiary. If you are receiving a reduced benefit because you claimed before full retirement age, your COLA is calculated on your reduced amount, not on what you would have received at full retirement age.

Frequently Asked Questions

Can I find an estimate of the 2026 COLA before October 2025?

News outlets and some financial websites publish estimates based on recent inflation trends, but these are not official predictions from Social Security. The actual COLA depends on inflation data from July through September 2025, which will not be final until October 2025. Estimates can be useful for planning, but they may not match the final number.

What if I disagree with the COLA amount Social Security tells me?

The COLA is calculated using a formula set by law and applied uniformly to all beneficiaries. You cannot dispute the percentage itself. If you believe there is an error in your benefit amount, you can contact Social Security to review your earnings record and payment history, but you cannot challenge the COLA calculation.

Does the COLA affect Medicare premiums?

Social Security has a "hold harmless" rule that protects most beneficiaries: your Medicare Part B premium cannot increase more than your COLA increase. However, new beneficiaries and higher-income beneficiaries may not receive this protection. Your Social Security notice will show whether hold harmless applies to you.

If there is no COLA in 2026, do I get no raise at all?

A zero COLA is rare but possible if inflation is flat or negative. It has happened only three times since 1975 (2009, 2010, and 2016). If it occurs in 2026, your benefit amount would stay the same as 2025. You would still receive your regular payment; it would just not increase.

How does the COLA affect my taxes on Social Security benefits?

The COLA increases your benefit amount, which may push you into a higher tax bracket if you have other income. Social Security benefits are taxable to the extent that your combined income (benefits plus other income) exceeds certain thresholds. A higher COLA could mean more of your benefits are subject to income tax, depending on your total income.
