The first 2027 COLA (cost-of-living adjustment) estimates pointed to 3.5%, but the final increase is 3.6%. For the average retired worker, that lifts the monthly check by $76 before deductions.
Policy analyst Mary Johnson and The Senior Citizens League projected 3.5% after the August inflation report, about $72-$73 on a $2,087 average benefit, according to early COLA analysis. The inspector general for the Social Security Administration confirmed the official 3.6% COLA on Oct. 14, 2026, topping the 2.8% paid for 2026, according to the SSA watchdog announcement.

Why did the estimate move to 3.6%?
The Bureau of Labor Statistics reported stronger September inflation for wage earners. Its CPI-W rose 3.9% from a year earlier, above 3.7% for headline CPI-U. Gasoline jumped 9.1% in September and drove over half the monthly gain, lifting the July-September average to 3.6%.
The Social Security Administration says the law sets the COLA from that quarter. It uses the average CPI-W for July through September versus the same quarter in the last COLA year. The Bureau of Labor Statistics calculates CPI-W each month.
How much more will you receive?
The chief actuary for the Social Security Administration estimates the average retired-worker check rises from $2,094 to $2,170, according to the SSA benefit effect table. That equals $76 a month and about $912 a year before deductions.

The Social Security Administration reports the increase covers about 76 million Americans. It pays nearly 72 million Social Security beneficiaries in January 2027 and about 7.3 million SSI recipients on Dec. 31, 2026.
How much will Medicare take back?
Medicare premiums come straight from your Social Security check. The 2026 Medicare Trustees Report projects the standard Part B premium at $209.50 for 2027, up $6.60 from $202.90, according to Trustees report coverage.
That deduction cuts a raise near $75 to roughly $68 for someone paying the standard premium. People with tax withholding, Part D premiums, or late-enrollment surcharges can keep less. Compare your December notice with your January deposit to see your exact net amount.
Do you need to do anything?
You do not need to apply for the COLA. Social Security makes the adjustment automatically and mails notices in December. Keep the December letter until your January deposit matches it.
- Check your mailed December notice for your new payment amount.
- Expect the higher Social Security payment in January 2027; SSI arrives Dec. 31, 2026.
- If you still work, note the taxable maximum rises to $192,300 in 2027 from $184,500.
