The 2026 COLA will be announced in October 2025

The Cost of Living Adjustment (COLA) for Social Security in 2026 will be announced on October 10, 2025. This is the percentage increase Social Security applies to all benefit payments each January to account for inflation over the past year. The exact amount depends on inflation data collected through September 2025, so no one knows the final number until that announcement date.

COLA increases are calculated by the Social Security Administration using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This index measures price changes for food, housing, transportation, medical care, and other goods and services. If prices rose significantly from October 2024 through September 2025, the COLA will be larger. If inflation was lower, the COLA will be smaller.

Every person receiving Social Security — whether retirement, disability, or survivor benefits — gets the same COLA percentage applied to their monthly payment. A spouse or child receiving benefits on your record also receives the same increase.

Key Takeaways

  • The 2026 COLA percentage will be announced on October 10, 2025, and takes effect in January 2026 benefit payments.
  • COLA is based on inflation measured by the Consumer Price Index and cannot be predicted with certainty until the official announcement.
  • The 2025 COLA was 3.2 percent, meaning a retiree receiving $1,800 per month saw their payment increase by about $58.
  • You do not need to do anything to receive the COLA increase — it is applied automatically to your benefit payment.
  • COLA increases affect Medicare premiums, so your net benefit increase may be smaller than the COLA percentage suggests.

How COLA is calculated and why it varies year to year

The Social Security Administration calculates COLA by comparing the average CPI-W for the third quarter of the current year (July, August, September) to the average for the third quarter of the previous year. If the 2025 average is higher than the 2024 average, the difference becomes the COLA percentage. If inflation was flat or negative, COLA is zero — benefits do not decrease.

COLA varies because inflation itself varies. When gas prices, grocery costs, and rent rise sharply, inflation is high and COLA is high. When prices are stable or falling, COLA is low or zero. The 2025 COLA was 3.2 percent because inflation from mid-2023 to mid-2024 averaged 3.2 percent. The 2024 COLA was 8.7 percent because inflation in 2023 was much higher. In 2022, COLA was 5.9 percent.

The CPI-W measures prices paid by urban wage earners and clerical workers, not all Americans. Rural workers, retirees, and self-employed people may experience different inflation rates for the goods they actually buy. However, Social Security uses this single index for all beneficiaries because it is published monthly by the Bureau of Labor Statistics and covers a consistent basket of goods over time.

What the 2026 COLA might be based on recent inflation trends

Predicting the exact 2026 COLA is impossible before October 2025, but you can watch inflation reports to get a sense of the direction. The Bureau of Labor Statistics publishes the Consumer Price Index monthly, usually in the middle of the month. These reports show whether prices are rising faster or slower than they were the previous month and year.

If you want to track this yourself, search for "CPI-W" on the Bureau of Labor Statistics website (bls.gov). The monthly reports show the index level for the current month and the same month one year ago. Divide the current month by the previous year's month, subtract 1, and multiply by 100 to see the year-over-year inflation rate. The COLA will roughly match the average of these monthly rates for July, August, and September 2025.

Historical COLA amounts show the range of increases you might see: the lowest COLA in recent decades was zero in 2010 and 2011 (when inflation was negative). The highest was 14.3 percent in 1980 (during a period of very high inflation). Most years fall between 1 and 4 percent. The 2026 COLA will likely fall somewhere in this typical range, but inflation can surprise in either direction.

How the COLA increase affects your actual benefit payment

When COLA is announced, the Social Security Administration applies it to your Primary Insurance Amount (PIA) — the benefit amount you earned based on your work history. If your PIA is $2,000 and COLA is 3 percent, your new benefit is $2,060. This increase appears in your January 2026 payment.

However, your net increase may be smaller because Medicare Part B and Part D premiums often rise at the same time. If you are enrolled in Medicare and your premiums are deducted from your Social Security check, the COLA increase is partially or fully offset by higher premiums. For example, if your benefit increases by $60 but your Medicare Part B premium increases by $40, your actual take-home increase is only $20.

If you are not yet receiving Social Security, the COLA increase does not affect your future benefit amount. Your benefit is calculated based on your actual earnings record at the time you claim, not on past COLA adjustments. However, COLA does increase the maximum benefit amount that Social Security can pay, which indirectly affects high earners.

When you will see the 2026 COLA in your payment

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

Social Security typically sends a notice in December 2025 showing your new benefit amount and explaining the COLA increase. This notice also shows any changes to Medicare premiums if you are enrolled. Keep this notice for your records, as it documents your new benefit amount for tax purposes and for any other programs that use your Social Security income to determine your may be able to access.

If you are receiving benefits on someone else's record (as a spouse, child, or survivor), you will receive the same COLA percentage increase. For example, if you receive a spousal benefit of $800 and COLA is 3 percent, your new benefit is $824.

COLA and taxes on Social Security benefits

A COLA increase may push some beneficiaries into a tax bracket where part of their Social Security becomes taxable. This happens because the income thresholds that determine whether benefits are taxed are not adjusted for inflation — they have been the same since 1984.

If you are single and your combined income (adjusted gross income plus nontaxable interest plus half your Social Security benefits) exceeds $25,000, up to 50 percent of your benefits may be taxable. If it exceeds $34,000, up to 85 percent may be taxable. If you are married filing jointly, the thresholds are $32,000 and $44,000. A COLA increase that pushes you over one of these thresholds means you will owe federal income tax on a portion of your benefits that was previously tax-free.

This is sometimes called "bracket creep," and it affects more beneficiaries each year as COLA increases accumulate. If you think this might explore to you, consider consulting a tax professional or using the Social Security Administration's online tax calculator to estimate your tax liability.

Frequently Asked Questions

Can I find out the 2026 COLA before October 2025?

No. The official COLA is announced on October 10, 2025, and cannot be known earlier. Some financial websites publish estimates based on inflation data through August or September, but these are guesses and often change. The only reliable number is the one Social Security announces in October.

What if inflation is negative in 2025 — will my benefit decrease?

No. Social Security has a "no-reduction" rule: COLA cannot be negative. If inflation is flat or negative, COLA is zero and your benefit stays the same. Your payment will not decrease due to COLA, though it could decrease if you have an overpayment that Social Security is recovering.

Does COLA explore if I am still working and haven't claimed Social Security yet?

COLA does not affect your future benefit amount. Your benefit is calculated based on your actual earnings record when you claim. However, COLA does increase the maximum benefit amount Social Security can pay, which indirectly affects the highest earners.

Will the 2026 COLA be higher or lower than 2025's 3.2 percent?

That depends on inflation between October 2024 and September 2025. If inflation is higher than it was in that period last year, COLA will be higher. If inflation is lower, COLA will be lower. Watch monthly CPI-W reports from the Bureau of Labor Statistics to track the trend, but the exact number will not be known until October 10, 2025.

How does COLA affect my Medicare premiums?

Medicare Part B and Part D premiums are set separately from COLA and often increase at different rates. In some years, premiums rise more than COLA, reducing your net benefit increase. In other years, premiums rise less. Social Security's notice in December 2025 will show both your new benefit amount and any premium changes so you can see your actual increase.
