October’s COLA Announcement Could Hand the Average Retiree a Bigger Monthly Check in 2027

In August, a retired worker collecting the average Social Security check got $2,088, according to the Social Security Administration’s latest monthly snapshot. On Oct. 14, that retiree finds out how much the check grows in January. Plenty of retirees will spend next week refreshing the news, and they have good reason to, since this raise is the only one most of them will get all year.

The raise is the cost-of-living adjustment, or COLA, the annual increase applied to every Social Security benefit. Federal law ties it to the Consumer Price Index for Urban Wage Earners and Clerical Workers. That is an inflation gauge known as CPI-W.

2 of 3 Inflation Readings Are Already Locked In

Take the average CPI-W reading for July, August and September. Compare it with the same three months a year earlier. The percentage gap becomes your raise.

July came in at 327.104 and August at 328.481. Last year’s third-quarter average, the bar this year is measured against, was 317.265. The September report, due Oct. 14, completes the calculation, and the official figure follows once it’s out.

Until then, everything is an estimate. As of September 17, The Senior Citizens League estimated 3.5%, down from 3.6% a month earlier.

On the same date, AARP estimated 3.6%, and the Committee for a Responsible Federal Budget had the lowest estimate at 3.2%. Kiplinger reported on September 30 that the final estimate had slid again even with prices still high.

Here is what that means in dollars: A 3.5% raise on the average retired worker’s check adds about $73 a month. Across the full range of estimates, the gross raise works out to roughly $67 to $75. Any result in that range beats the 2.8% raise for 2026, and a 3.6% raise would be the largest since 2023.

Medicare Takes Its Cut Before the Raise Reaches Your Bank

For most retirees on both programs, the Medicare Part B premium comes straight out of the Social Security check. The raise announced in October and the January deposit increase are two different numbers. Last year, the standard Part B premium rose to $203 for 2026, up $18. That jump took nearly a third of the 2026 raise.

The 2027 outlook is softer. The 2026 Medicare Trustees Report projects a standard premium of about $210, an increase of $7. The Centers for Medicare & Medicaid Services usually sets the official premium in November. With a 3.5% raise, the average retiree’s deposit grows by about $66 a month, or nearly $800 over the year. That is still a real raise, just smaller than the reported number.

Higher-Income Retirees Can See Most of the Raise Disappear

Medicare charges extra premiums, called income-related monthly adjustment amounts, to beneficiaries with higher incomes. In 2026, those surcharges start above $109,000 of modified adjusted gross income for single filers and $218,000 for joint filers. Roughly 8% of people on Part B pay them. In the first surcharge tier, the monthly Part B premium is $284.

The surcharge looks back two years, so your 2025 tax return sets your 2027 premium. A Roth conversion or home sale in 2025 can push you into a surcharge bracket, reducing a $73 raise to very little.

How to Budget Before and After the October 14 Announcement

First, plan around the net figure. When your benefit notice arrives later this year, find two lines: (1) the new gross benefit and the Medicare deduction, and (2) the difference between those lines is your real spending money. If you pay Part D drug premiums through your check, include those too, since 2027 Part D costs are already drawing attention.

Second, if your income dropped after 2025 because you retired, lost a spouse, or stopped working, you can ask Social Security to lower your Medicare surcharge. A surcharge pegged to an income you no longer have is one of the easiest costly mistakes to fix, and the fix only happens if you file the request (we mapped the full set of Medicare traps retirees run into, surcharges included, in a free guide here).

The official figure will likely land within the 3.2% to 3.6% range. For the typical retiree, that means about $60 to $69 more per month after Medicare takes its share. That beats last year. Your number depends on your benefit, income history, and drug plan, so check your notice instead of the reported.
