Social Security's COLA Adds $50 a Month, But Medicare Premium Hikes Cut It Down

"The headline number sounds fine: a 2.8% cost-of-living adjustment (COLA) for 2026, the largest piece of inflation protection most retirees have. Weeks later, her Medicare Part B notice arrives, and the math starts to shrink. By January, the raise on paper is much smaller than the bump in her checking account."

"Start with the average retired worker. The Social Security Administration (SSA) announced on October 24, 2025 that benefits would rise 2.8% in 2026, lifting the typical retired-worker check from $2,015 to $2,071 a month. That's roughly a $56 gross raise. Now subtract Medicare. The standard Part B premium climbed to $202.90 in 2026, up $17.90 from $185.00 in 2025, a jump of nearly 10%."

"Because most retirees have Part B pulled directly out of their Social Security deposit, that increase comes off the top before the money hits the bank. The $56 gross raise becomes about a $38 net increase. Round it down a little for federal withholding on benefits and the headline framing of $50 turning into $32 is exactly the experience many will see at their bank."

"The single most important rule underneath all of this is the hold-harmless provision in Section 1839(f) of the Social Security Act. In any year the dollar increase in your Part B premium would exceed your dollar COLA, hold-harmless caps the premium so your"

Social Security benefits are scheduled to rise 2.8% for 2026, increasing a typical retired-worker check from $2,015 to $2,071 per month. Medicare Part B premiums also increase, with the standard premium rising to $202.90 in 2026 from $185.00 in 2025. Because Part B premiums are commonly deducted directly from Social Security payments, the premium increase reduces the amount retirees receive in their bank deposits. The $56 gross Social Security raise can shrink to about a $38 net increase after accounting for the higher Part B premium, with additional reductions from federal withholding. A hold-harmless rule in the Social Security Act limits premium increases when they exceed the COLA increase.
