But is it still a raise if a chunk of it disappears before it hits the bank account? That’s what has been echoing in the minds of retirees since confirmation came from the government that Medicare Part B premiums will, in fact, rise in 2026, cutting into that increase many had been counting on.
The cost-of-living adjustment for Social Security will rise 2.8% next year, adding about $56 a month for retirees receiving the average benefit of $2,008. But the standard Medicare Part B premium will rise by $17.90, bringing the monthly cost to $202.90. Because most beneficiaries have their premiums automatically deducted from their Social Security checks, many will see that $56 boost falls closer to $38. This pattern has become familiar, and retirement advisers say many people underestimate how often health‑care costs eat into annual COLAs.
For those receiving smaller benefits, the erosion is even sharper: A retiree collecting $600 a month would see a COLA of only $16.80 — less than the Part B increase. That’s where the hold harmless rule comes in. “A Part B increase of this size would trigger the hold harmless provision for Social Security recipients with a Social Security benefit of $640 or less,” said Mary Johnson, a Social Security and Medicare policy analyst. She added that the provision prevents their checks from shrinking, even though their premium increase technically would be larger than their COLA. Shannon Benton of the Senior Citizens League says, “Under the hold harmless provision that applies to some beneficiaries, the increase in Medicare Part B premiums is limited to the dollar amount of a recipient’s COLA.”
Those protections do not reach everyone, however. New beneficiaries, as well as anyone who has Medicare Advantage or Part D premiums deducted automatically, are still exposed, as are higher‑income households. Since 2007, Medicare has based premiums on income, and about 8% of Part B enrollees pay higher premiums because of those adjustments. A joint filer whose income is between $274,000 and $342,000 could pay $405.80 a month in 2026. Reference materials indicate that income‑related adjustments are assessed on a sliding scale, with retirees who exceed certain key thresholds-often by only a small amount-finding themselves subject to surcharges due to IRMAA. As discussed in an analysis on Medicare planning, these surcharges are based on tax returns two years earlier and represent a “cliff”: even a one‑dollar rise in income can push someone into higher premiums. Understanding how COLAs are computed can help explain why these adjustments so often feel smaller than expected.
According to a federal explanation of COLA methodology, the COLA is based on the CPI-W, a measure that reflects the spending patterns of urban wage earners. Because retirees generally spend more on medical care area which tends to rise faster than general inflation, CPI-W often understates the price changes older adults face. The broader review noted that the CPI-W has tended to grow more slowly than indexes that are targeted specifically for older consumers, a factor that probably contributes to perceptions that annual benefit increases fail to keep pace with household costs. Practical steps can help retirees steady their budgets as these changes unfold. Financial counselors often recommend reviewing Medicare options during open enrollment, particularly because premiums for Medicare Advantage and Part D can vary so much. Beneficiaries who are unsure if high premiums reflect outdated income can ask for a reassessment if they have experienced a qualifying life‑changing event.
Similarly, budget specialists encourage reviewing other recurring health‑related expenses, using resources such as comparing prescription plans and annual reviews of medications to keep routine costs in check. Articles that give guidance on ways retirees can manage rising Medicare expenses underscore how this thoughtful planning often helps offset some of the pressure created by the premium increases themselves. These changes, even in small increments, show just how much modifications in Medicare pricing can affect monthly income in retirement and perhaps why so many track these policy updates closely as they head into the new year.
