The 2026 COLA will be announced in October 2025

The Cost of Living Adjustment (COLA) for 2026 Social Security benefits will be announced on the second Thursday of October 2025. The Social Security Administration calculates COLA each year based on inflation data from the third quarter — July, August, and September. That number becomes the percentage increase applied to all Social Security checks starting in January 2026.

You cannot know the exact 2026 COLA until October 2025, because it depends on inflation that hasn't happened yet. What you can do now is understand how COLA works, what it means for your monthly payment, and how to plan around the uncertainty.

Key Takeaways

  • The 2026 COLA percentage will be announced in October 2025 and takes effect on January 1, 2026 for all beneficiaries.
  • COLA is calculated from inflation data collected during July, August, and September of the current year.
  • Your new 2026 benefit amount will appear on your Social Security statement in December 2025.
  • COLA affects retirement, survivor, and disability benefits equally — everyone gets the same percentage increase.
  • If you are still working and earning above the earnings limit, COLA does not change how much of your benefit is withheld.

How the COLA calculation works

The Social Security Administration uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to measure inflation. This index tracks the cost of goods and services that working people buy — food, housing, transportation, medical care, and utilities. The SSA compares the average CPI-W for July, August, and September of the current year to the same three months of the previous year. The percentage change becomes that year's COLA.

If inflation was higher in those three months, COLA is higher. If inflation was lower, COLA is lower. If there was deflation — prices actually fell — COLA would be zero, and benefits would not decrease. This has happened only three times since COLA began in 1975: in 2010, 2011, and 2016.

The COLA formula is the same every year and does not change based on politics, the economy, or how much money Social Security has. It is a mechanical calculation tied directly to inflation.

What 2026 COLA means for your monthly check

Your January 2026 benefit will be your current benefit amount multiplied by (1 + the 2026 COLA percentage). If the COLA is 2.5%, a person receiving $1,800 per month would receive $1,845 starting in January 2026. The increase is applied to your primary insurance amount — the base benefit you earned — and any family benefits tied to your record are adjusted by the same percentage.

The increase appears automatically. You do not need to do anything, contact Social Security, or reapply. Your December 2025 Social Security statement will show your new 2026 amount. If you receive your benefit by direct deposit, the new amount will hit your bank account on the third of January 2026 (or the next business day if the third falls on a weekend or holiday).

COLA does not affect the earnings limit for people who are still working. If you are under full retirement age and earning above the limit, Social Security will still withhold $1 for every $2 you earn above the threshold, regardless of your COLA increase.

Why COLA matters for retirement planning

COLA protects your purchasing power over time. Without it, your Social Security check would buy less and less each year as prices rose. With COLA, your benefit keeps pace with inflation — though not perfectly, because CPI-W does not measure exactly what older adults spend money on. Retirees tend to spend more on medical care and housing than the average worker, so COLA sometimes lags behind their actual cost increases.

If you are planning to claim Social Security in the future, you cannot predict your exact benefit amount because COLA will change your primary insurance amount between now and when you claim. Estimates from the Social Security Administration account for assumed future COLA increases, but those are projections, not guarantees. The actual COLA will depend on inflation in the years ahead.

How COLA affects survivor and disability benefits

Everyone receiving benefits on a Social Security record — the worker, their spouse, their children, and their survivors — receives the same COLA percentage increase. If you are receiving a widow's benefit or a child's benefit based on a parent's or grandparent's record, your 2026 benefit will increase by the same percentage as the primary beneficiary's benefit.

Supplemental Security Income (SSI), which is a separate program for low-income individuals, also receives a COLA adjustment, but it is calculated slightly differently and announced at the same time. The 2026 SSI federal benefit rate will increase by the same percentage as Social Security, though some states add their own supplement and may adjust it differently.

What to do before October 2025

Create or update your my Social Security account at ssa.gov if you do not already have one. This account shows your current benefit amount, your earnings record, and your projected benefits at different claiming ages. You can check it anytime to see your current information and will receive your 2026 benefit amount there in December 2025.

If you are still working and close to the earnings limit, track your income carefully. COLA will not change the earnings limit for 2026 — that is set separately by law — but your higher benefit amount might change how much you owe back if you earn above the threshold. If you are self-employed, keep records of your net earnings so you can report them accurately to Social Security.

If you are receiving benefits and have experienced a major life change — marriage, divorce, a child turning 19, or a death in the family — contact Social Security before the new year to make sure your record is correct. COLA is applied to your current benefit, so errors now will carry forward into 2026.

Frequently Asked Questions

When will I know the exact 2026 COLA percentage?

The Social Security Administration announces COLA on the second Thursday of October each year. For 2026, that is October 8, 2025. You will see the percentage announced in news reports and on the SSA website that day.

Can I claim Social Security before 2026 to lock in my current benefit?

No. Your benefit amount is determined by your age and earnings record when you claim, not by when you claim relative to a COLA announcement. Claiming earlier means a permanently lower monthly benefit, regardless of COLA. The COLA increase applies to whatever benefit amount you are receiving.

Does COLA apply if I have not started claiming yet?

Yes. COLA increases your primary insurance amount — the base benefit you earned — every year, whether you are claiming or not. When you do claim, your benefit will be based on your updated primary insurance amount, which includes all the COLA increases since you became may be able to access.

What if I am still working and earning above the limit?

COLA increases your benefit amount, but it does not change the earnings limit or how much Social Security withholds. If you earn above the limit, you will owe back $1 for every $2 over the threshold, applied to your new, higher benefit amount. Once you reach full retirement age, the earnings limit no longer applies.

How does COLA affect my taxes on Social Security benefits?

COLA increases your benefit amount, which could push more of your benefits into the taxable range if your combined income crosses the threshold. Combined income includes your adjusted gross income, nontaxable interest, and half your Social Security benefits. A higher benefit might mean more of it is subject to federal income tax, depending on your other income sources.
