The Social Security Administration's 2026 cost-of-living adjustment delivers a 3.4 percent raise to the average retired worker, or about $56 per month, beginning with January 2026 checks already in the mail. [1] The Centers for Medicare and Medicaid Services separately announced a Medicare Part B standard premium increase of $45, from $185 in 2025 to $230 in 2026. [2] The arithmetic is in the headline of this article. After the premium increase, the average retiree who also carries standard Part B sees a net monthly raise of roughly $11.

Two numbers, one account. The COLA and the Part B premium are deducted and credited against the same check for roughly 85 percent of Medicare beneficiaries, because most enrollees pay their premium through automatic deduction from their Social Security payment. [2] A raise of $56 minus a premium increase of $45 is the arithmetic of a raise of $11. AARP's analysis, published this week alongside Kiplinger's and the National Committee to Preserve Social Security and Medicare's, arrives at the same number. [1] [3]

Eleven dollars is real money in some household budgets and less than a week of groceries in most. The more useful frame is the pace. Shelter inflation, per the Bureau of Labor Statistics' March Consumer Price Index release, rose 3.9 percent year-over-year. Food-at-home rose 3.1 percent. Medical care services, which includes the physician visits and prescription drugs Medicare enrollees disproportionately consume, rose 4.4 percent. [3] The COLA formula uses a different index — CPI-W, the index for urban wage earners and clerical workers, which weighs goods retirees do not buy in the same proportion as the goods they do. CPI-W came in lower than the general CPI for the third consecutive year. The raise is calibrated to a basket that is not quite the basket retirees shop from.

There is a second arithmetic underneath this one, harder to see and worth naming. Part B premiums are indexed, by statute, to projected Medicare physician spending. Physician spending is up because medical inflation is up. Medical inflation is up partly because of generalized price pressure and partly because of specific categories — biologics, surgical supplies, the portion of the medical-device supply chain routed through the Strait of Hormuz — that the war has made more expensive. The $45 premium increase is, in modest part, a line item the war added. [2] The SSA's COLA announcement does not mention the war. The CMS Part B announcement does not mention the war. The retiree whose check is $11 larger does not have to, either; she only has to buy groceries.

What a beneficiary can do about it, practically, divides into three decisions. The first is whether to switch from traditional Medicare to Medicare Advantage. MA plans typically bundle Part B and a supplemental benefit at a single premium, and some zero-premium MA plans will fully absorb the Part B increase. The trade-off is a narrower provider network and utilization-management requirements that make MA a worse fit for beneficiaries with complex conditions. The second decision is whether to qualify for the Medicare Savings Programs, which cover Part B premiums entirely for beneficiaries under specific income thresholds. The 2026 thresholds are $1,695 per month for a single beneficiary and $2,300 for a couple, and CMS estimates that roughly three million eligible beneficiaries do not enroll. [2] The third decision — the one nobody wants to talk about — is whether to delay filling prescriptions and delay doctor visits because the check covers less. Pharmacies report that Part D adherence drops measurably in the first quarter after a premium increase. The drop has health consequences that show up later, in different line items.

The service journalism version of this story is that the SSA and CMS publish their numbers separately because they are separate agencies, that AARP does the subtraction because it is a membership organization whose members do the subtraction themselves, and that the net raise this year is $11. The policy version is that the COLA formula, written in 1972 and amended in 1983, produces an adjustment that reliably fails to keep pace with the expenses of the population the program was designed to serve. A $56 raise that yields $11 in the pocket is not a system failure. It is the system working as designed.

The check will arrive next month. The premium has already been deducted. The raise is what is left.
