Social Security benefits will rise in 2026 based on inflation measured through September 2025

Every January, Social Security raises the monthly benefit amount for people already receiving checks. The increase is called a Cost-of-Living Adjustment (COLA), and it is set by a formula: the Social Security Administration measures inflation using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from July, August, and September of the prior year, then applies that percentage to all benefit payments starting in January.

The 2026 COLA will be announced in October 2025. Until then, the exact percentage is unknown — it depends on inflation data that has not yet been collected. The Social Security Administration will publish the official figure on its website and send notices to current beneficiaries in December 2025, showing the new monthly amount effective January 2026.

If you receive Social Security retirement, survivor, or disability benefits, the raise applies automatically. You do not need to do anything. If you are still working and have not yet claimed benefits, the COLA does not affect you yet — it will apply to your benefit amount whenever you do claim.

Key Takeaways

  • The 2026 COLA is calculated from inflation data collected July through September 2025 and will be announced in October 2025.
  • Current beneficiaries receive the raise automatically in January 2026 with no action required on their part.
  • The COLA percentage applies equally to all benefit types: retirement, survivor benefits, and disability payments.
  • People who have not yet claimed Social Security are not affected by the 2026 COLA until they begin receiving benefits.
  • Medicare premiums may also change in 2026, which can offset part of the benefit increase for some beneficiaries.

How the COLA formula works and why it varies year to year

Social Security uses the CPI-W, a specific inflation measure that tracks price changes for urban workers' everyday expenses: food, housing, transportation, medical care, and other goods and services. The Social Security Administration averages the CPI-W for July, August, and September, compares it to the same three months from the prior year, and calculates the percentage change. That percentage becomes the COLA.

The COLA has ranged from zero (in years when inflation was flat or negative) to over 8 percent (in 2022, when inflation was high). In recent years, COLAs have been 8.7 percent (2023), 3.2 percent (2024), and 2.5 percent (2025). The 2026 COLA will depend entirely on whether prices rise or fall between mid-2024 and mid-2025.

This formula means the COLA is not a choice or a discretionary raise — it is a mechanical adjustment tied to inflation. Congress does not vote on it each year. The Social Security Administration simply applies the formula and announces the result.

When you will see the 2026 raise on your benefit check

If you receive Social Security benefits by direct deposit or check, your January 2026 payment will reflect the new, higher amount. The timing depends on your birth date. Social Security pays beneficiaries on a staggered schedule: people born on the 1st through the 10th of any month receive payments on the second Wednesday of each month, those born the 11th through the 20th receive payments on the third Wednesday, and those born the 21st through the 31st receive payments on the fourth Wednesday.

Your first payment with the 2026 COLA will arrive according to your regular payment schedule in January 2026. You will also receive a notice in December 2025 showing your new monthly benefit amount and explaining the COLA percentage.

If you receive benefits through a representative payee (someone who manages your benefits on your behalf), the payment goes to that person's account, but the amount will still increase by the COLA percentage.

How Medicare premiums interact with your Social Security raise

Many people who receive Social Security also pay Medicare Part B premiums (medical insurance) and Part D premiums (prescription drug coverage). These premiums can increase each year, sometimes offsetting part or all of the COLA raise.

Social Security has a hold-harmless provision that protects most beneficiaries: if your Medicare Part B premium increases, your net Social Security benefit cannot go down. In other words, if the COLA raises your benefit by $50 but your Medicare premium rises by $30, you keep the full $50 and pay the higher premium. However, people who are new to Medicare or who have other income sources may not be protected by hold-harmless and could see their net benefit reduced if premiums rise sharply.

The 2026 Medicare premiums will be announced in late 2025, around the same time as the COLA. If you are concerned about how the premium changes might affect your budget, you can review both figures once they are published.

What the 2026 COLA means for your long-term benefits

The COLA is permanent — once your benefit amount increases in January 2026, that new amount becomes your baseline for future years. Future COLAs will be calculated on top of the 2026 amount, not on your original benefit amount from when you first claimed.

This compounding effect means that over decades, COLAs significantly increase the total amount you receive. Someone who claimed at 62 in 2010 and received a $1,000 monthly benefit has received multiple COLAs since then, and their current benefit is substantially higher. The 2026 COLA will add to that history.

If you are still working and considering when to claim Social Security, remember that the COLA applies to whatever benefit amount you have at the time you claim. Delaying your claim increases your base benefit amount (by about 8 percent per year between your full retirement age and 70), and then future COLAs apply to that higher base. This is one reason financial advisors often discuss the trade-off between claiming early and claiming later.

Planning your 2026 budget with the COLA in mind

Once the 2026 COLA is announced in October 2025, you can estimate your new monthly benefit by multiplying your current benefit by the COLA percentage and adding it to your current amount. For example, if you receive $2,000 per month and the COLA is 2.5 percent, your new benefit would be approximately $2,050.

Use this estimate to review your 2026 budget. If you rely on Social Security as your primary income, the raise may help offset inflation in your own expenses. If you have other income sources or savings, the COLA may simply keep your purchasing power roughly stable rather than increase it.

If you receive Supplemental Security Income (SSI) in addition to Social Security, the COLA also applies to SSI payments, and SSI has its own separate hold-harmless rules. Check your SSI notice in December 2025 to see how both programs' increases affect your total monthly income.

Frequently Asked Questions

When will the 2026 COLA be announced?

The Social Security Administration announces the COLA in October of the year before it takes effect. The 2026 COLA will be announced in October 2025. You will receive a notice in December 2025 showing your new benefit amount starting in January 2026.

Can I estimate what the 2026 COLA will be right now?

No — the COLA is based on inflation data from July through September 2025, which has not yet occurred. Some financial websites publish COLA forecasts based on recent inflation trends, but these are educated guesses, not official figures. The actual COLA will be announced in October 2025.

Does the COLA apply if I haven't claimed Social Security yet?

The 2026 COLA does not affect your benefit amount until you claim. Once you do claim, your starting benefit will be based on your earnings record and your age at claim, and future COLAs will apply to that amount. Delaying your claim past your full retirement age increases your base benefit, and then COLAs compound on top of that higher amount.

Will my Medicare premium increase offset the COLA raise?

For most current beneficiaries, the hold-harmless provision protects you: your net Social Security benefit cannot decrease even if Medicare premiums rise. However, people new to Medicare or with other income sources may not have this protection. Both the COLA and Medicare premiums are announced in late 2025, so you can see the full picture then.

Is the COLA the same for everyone receiving Social Security?

Yes — the COLA percentage applies to all beneficiaries equally, whether you receive retirement benefits, survivor benefits, or disability benefits. The dollar amount of your raise depends on your current benefit amount, but the percentage increase is the same for everyone.
