The 2026 COLA Sounds Great — Until You Do the Math
In October 2025, the Social Security Administration announced a 2.8% cost-of-living adjustment (COLA) for 2026. That translates to an average increase of about $56 per month for retirees, bringing the average benefit from $2,015 to $2,071.
That’s the headline. Here’s the reality.
Medicare Part B Ate Most of It
The standard monthly premium for Medicare Part B rose by approximately $17.90 per month in 2026, reaching $202.90. That increase — roughly 10% — is automatically deducted from most Social Security checks.
So the net increase for a typical retiree enrolled in Medicare is closer to $38 per month. Not $56.
For married couples where both spouses are on Medicare, that’s $35.80 per month going straight to healthcare premiums — before they’ve bought a single prescription.
Does the COLA Keep Up With Real Costs?
The COLA is calculated using the Consumer Price Index for Urban Wage Earners (CPI-W). But seniors don’t spend money the same way working-age adults do. Retirees spend a much larger share of their income on healthcare, housing, and food — all of which have risen faster than the general CPI.
According to advocacy groups like The Senior Citizens League, the current COLA calculation consistently underestimates the real cost increases that retirees face.
What You Can Do
Check your Medicare costs. If your income changed, you may be paying more (or less) than the standard premium. High-income surcharges (IRMAA) can significantly increase Part B and Part D premiums.
Review your Medicare Advantage plan. Plans change every year. A plan that was a good deal in 2025 may cost more or cover less in 2026. Open Enrollment runs October 15 through December 7 each year.
Claim the new $6,000 senior tax deduction if you’re 65 or older. It won’t increase your Social Security check, but it can reduce your overall tax burden.
Check your benefit statement. Log into my Social Security to see your exact 2026 benefit amount after the COLA and Medicare deduction.
