For three years running, Medicare Part B premium increases have consumed a meaningful portion, and sometimes all of, Social Security’s annual raise. Current projections show the Social Security COLA outpacing the Part B premium increase for the first time since 2023. This is good news, as traditional Medicare enrollees could actually keep more cash in their pocket.
Here’s what’s driving the change and what it means for your monthly check.
Editor’s note: All 2027 COLA projections are from The Senior Citizens League and independent analyst Mary Johnson, current as of mid-July 2026. The projected 2027 Part B premium is from the 2026 Medicare Trustees Report.

Why this could be the first meaningful win since 2023
Current forecasts put the 2027 COLA at roughly 3.7% to 3.8%, while the 2026 Medicare Trustees Report estimates the standard Part B premium rising to about $209.50 a month, an increase of $6.60, or roughly 3.25%.
If those projections hold, the COLA would outpace the premium increase for the first time since 2023, allowing retirees to keep more of their annual benefit adjustment.

Recent years have told a very different story
Between 2024 and 2026, Medicare Part B premiums increased by 6.0%, 5.8%, and 9.7%, respectively. During the same period, Social Security COLAs came in at just 3.2%, 2.5%, and 2.8%.
Since Part B premiums are typically deducted directly from Social Security benefits, many retirees saw little of their annual increase reflected in their monthly deposits.
Why the 9.7% premium hike in 2026 stung so much
The 2026 Part B premium jumped from $185 to $202.90, a $17.90 monthly increase. Against the 2026 COLA of 2.8%, a retiree with a $2,000 benefit received a $56 monthly raise. After the $17.90 premium increase was deducted, their net gain was just $38.10.
Aside from the 8.7% COLA in 2023, premium hikes have largely outpaced benefit increases in recent years.

The projected dollar increase looks more encouraging
Current forecasts point to a stronger outcome than retirees have experienced in recent years. Inflation has remained elevated enough to support another above-average COLA, while projected Medicare premium growth has slowed considerably.
The Senior Citizens League and analyst Mary Johnson currently estimate the 2027 COLA at 3.7% to 3.8%. If those projections hold, Social Security benefits would outpace Part B premium growth for the first time since 2023.
What it could mean for the average retiree’s check
The average monthly Social Security benefit for retired workers was $2,084.40 in June 2026. A 3.8% COLA would increase that to about $2,163.61, adding roughly $79.21 per month.
After subtracting the projected $6.60 increase in the standard Part B premium, the net gain would be about $72.61 monthly. While not dramatic, it’s a noticeable improvement over recent years.
Nothing is official yet
Despite the encouraging projections, nothing has been finalized yet. The Social Security Administration calculates each year’s COLA by comparing the average CPI-W (Consumer Price Index for Urban Wage Earners and Clerical Workers) data for July, August, and September with the same three-month period a year earlier.
The official 2027 COLA arrives in mid-October 2026, while Medicare announces the 2027 Part B premium in November 2026, leaving both figures subject to change.

Inflation determines the final COLA
The COLA depends entirely on inflation, not market performance or congressional decisions. The CPI-W was up 3.5% over the 12 months ending June 2026, helping push current COLA estimates to 3.7%–3.8%.
However, only July, August, and September inflation counts toward the official calculation. If prices continue cooling, the final adjustment could shrink. If inflation rebounds, retirees could see a larger increase than currently projected.
Health care costs still deserve close attention
According to Fidelity’s latest estimate, someone retiring at age 65 in 2026 could spend about $185,500 on healthcare and medical expenses over the course of retirement. That figure extends well beyond the standard Medicare Part B premium, covering many of the costs retirees pay themselves.
Prescription drugs, Medigap coverage, dental care, and other out-of-pocket expenses could still rise much faster than inflation.
A stronger net benefit could improve monthly cash flow
Keeping more of each COLA may not dramatically change retirement finances, but it may improve monthly cash flow. Based on the current projections, the average retired worker could keep roughly $72.60 more per month after the estimated Part B premium increase.
That’s about $871 annually, enough to offset part of a year’s utility bills, prescription costs, or groceries without tapping retirement savings prematurely.

Other retirement income still matters
A favorable COLA shouldn’t replace broader retirement planning. Inflation adjustments protect purchasing power, but they’re only one source of financial security. Maintaining emergency savings, adopting the 4% withdrawal strategy from retirement accounts, and reviewing investment allocations remain just as important.
Diversified income sources help retirees absorb unexpected expenses even when future COLAs are smaller than anticipated.
Bottom line
A projected 3.7% to 3.8% COLA currently exceeds the estimated 3.25% increase in Medicare Part B premium, meaning more of 2027’s raise may remain in retirees’ monthly checks. That’s an encouraging sign, but it’s still wise to prepare yourself financially without relying on projected figures.
Wait for the official COLA announcement in October and the Part B premium announcement in November 2026 before adjusting your retirement budget.
