The 2026 Social Security benefit increase will be announced in October 2025

Social Security benefits increase once per year, based on a formula tied to inflation. The increase for 2026 will be announced in mid-October 2025, when the Social Security Administration releases the Cost of Living Adjustment (COLA) for that year. The actual increase takes effect on January 1, 2026, and your first payment at the new rate will arrive in February 2026 (since Social Security pays in arrears).

The size of the increase depends entirely on inflation data from the previous year. If inflation was high, the COLA will be high. If inflation was low, the COLA will be low. There is no minimum or maximum — the formula is automatic and does not require Congress to vote or approve anything.

You do not need to do anything to receive the increase. If you are already collecting Social Security, the higher payment will arrive automatically. If you have not yet started collecting, the increase will apply to whatever benefit amount you are may have access to to when you do start.

Key Takeaways

  • The 2026 COLA will be announced in October 2025 and takes effect January 1, 2026, with the first payment arriving in February 2026.
  • The increase is calculated by the Social Security Administration using a formula based on inflation data; Congress does not vote on it.
  • Current beneficiaries receive the increase automatically with no action required on their part.
  • The exact percentage increase will not be known until October 2025, because it depends on inflation figures released by the Bureau of Labor Statistics.

How the COLA formula works

The COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures inflation across goods and services. The Social Security Administration compares the average CPI-W for July, August, and September of one year to the average for the same three months of the previous year. That percentage change becomes the COLA for the following year.

For example, if the average CPI-W for July–September 2025 is 3 percent higher than the average for July–September 2024, then the 2026 COLA will be 3 percent. Every beneficiary's payment increases by that same percentage, regardless of how much they receive or when they started collecting.

The formula has been in place since 1975. Before that, Congress voted on benefit increases case by case. The automatic formula was created to remove politics from the process and ensure that benefits keep pace with the cost of living.

What the increase means for your monthly payment

If you receive $1,500 per month in 2025 and the 2026 COLA is 2.5 percent, your 2026 payment will be $1,537.50 per month — an increase of $37.50. The exact dollar amount you receive depends on your current benefit amount, which is based on your earnings history and the age at which you started collecting.

The increase applies to all types of Social Security payments: retirement benefits, survivor benefits, and disability benefits. If you receive benefits as a spouse or child of a worker, your payment increases by the same percentage as the worker's primary benefit.

If you have not yet started collecting Social Security, the increase affects the benefit amount you will receive when you do start. Starting later means a higher monthly payment, because your benefit grows by the COLA each year you wait (up to age 70).

When you will see the increase in your account

The COLA is announced in October 2025. Social Security then recalculates all benefit amounts and updates its payment schedule. Your first payment at the new rate will arrive in February 2026, which covers benefits for January 2026.

If you receive your payment by direct deposit, the money will appear in your bank account on your regular payment date in February. If you receive a paper check, it will arrive by mail on your regular payment date. Social Security does not send a separate notice about the increase — it simply appears in your payment.

You can check your current benefit amount anytime by logging into your my Social Security account at ssa.gov. After October 2025, that account will show your updated 2026 benefit amount.

How the increase affects Medicare premiums

Medicare Part B premiums (for doctor and outpatient services) are deducted from Social Security payments for most beneficiaries. When Social Security benefits increase, Medicare premiums may also increase, which means some of your COLA increase goes toward higher premiums.

However, there is a hold harmless provision that protects most beneficiaries. If your Medicare Part B premium increases, your Social Security payment cannot decrease — it can only stay the same or go up. This means you will not lose money if premiums rise. The hold harmless rule does not apply if you are new to Medicare or if you did not pay Medicare premiums from your Social Security check in the previous year.

The Medicare Part B premium for 2026 will be announced in November 2025, after the COLA is known. You will receive a notice in December 2025 showing your new Medicare premium and your new Social Security payment amount.

Past COLA increases and what they tell you

The COLA has varied widely over the past decade. In 2022, it was 8.7 percent — the highest in 40 years, because inflation spiked after the pandemic. In 2023, it was 8.8 percent. In 2024, it dropped to 3.2 percent. In 2025, it is 3.2 percent again. These swings show that the COLA is unpredictable and depends entirely on what happens in the broader economy.

You cannot predict the 2026 COLA based on past years. The only way to know is to wait for the October 2025 announcement. Some financial news outlets publish forecasts in the months before the announcement, but these are educated guesses, not official figures.

What to do if you are not yet collecting Social Security

If you have not started Social Security, the 2026 COLA will affect your future benefit amount. The longer you wait to start, the higher your monthly payment will be — both because of annual COLAs and because of the delayed retirement credits you earn for each month you wait past your full retirement age.

Full retirement age depends on your birth year and ranges from 66 to 67. If you start at full retirement age, you receive 100 percent of your primary insurance amount. If you start at 62, you receive a reduced amount. If you start at 70, you receive a larger amount. The COLA applies to all of these scenarios — your benefit grows by the COLA percentage each year, regardless of when you start.

You can view your estimated benefit amounts at different ages by logging into your my Social Security account. Those estimates are updated each year to reflect the current COLA.

Frequently Asked Questions

Will the 2026 COLA be higher or lower than 2025?

No one knows until October 2025. The COLA depends on inflation data from July through September 2025. If inflation is higher than it was in the same months of 2024, the COLA will be higher. If inflation is lower, the COLA will be lower. Financial forecasters publish predictions, but these are not official.

Do I need to do anything to receive the increase?

No. If you are already collecting Social Security, the increase is automatic and will appear in your February 2026 payment. You do not need to contact Social Security or take any action.

Will my Medicare premium go up by the same amount as my Social Security increase?

Not necessarily. The COLA and the Medicare Part B premium increase are calculated separately. Your Social Security payment will increase by the COLA percentage, but your Medicare premium may increase by a different percentage. The hold harmless rule ensures your payment does not decrease if premiums rise.

What if I am on Supplemental Security Income (SSI) instead of regular Social Security?

SSI also receives a COLA increase on the same schedule as Social Security. The increase takes effect January 1, 2026, and your first payment at the new rate arrives in February 2026. The percentage increase is the same for both programs.

Can I find out my exact 2026 benefit amount before October 2025?

No. Your exact benefit amount cannot be calculated until the COLA is announced. You can see an estimate in your my Social Security account, but that estimate will change once the official COLA is released in October 2025.
