For most beneficiaries, the core Medicare costs in 2026 are:
If your income is above $109,000 (single) or $218,000 (married), you pay an IRMAA surcharge on top of the standard rates. Use our IRMAA calculator to find your exact amount.
IRMAA (Income-Related Monthly Adjustment Amount) is an additional charge on your Medicare Part B and Part D premiums if your income exceeds certain thresholds. In 2026, it applies to:
IRMAA is calculated based on your tax return from 2 years prior — so your 2026 premiums are based on your 2024 income. If your income has dropped significantly, you may appeal the determination using SSA Form SSA-44.
In 2026, the Medicare Part D out-of-pocket cap is $2,100. Once you've spent $2,100 on covered prescription drugs in a year, your plan pays 100% for the rest of the year — no more cost-sharing for covered drugs.
This is an increase from the 2025 cap of $2,000 and is part of the Inflation Reduction Act's drug pricing reforms. Learn more about how the cap works →
Medicare eligibility begins at age 65. Your Initial Enrollment Period (IEP) is a 7-month window: 3 months before your 65th birthday month, your birthday month, and 3 months after. Enrolling during the first 3 months ensures coverage starts on your birthday month.
If you're still covered by employer insurance at 65, you may delay enrollment without penalty — you'll have a Special Enrollment Period when that coverage ends. Full enrollment guide →
Medigap (Medicare Supplement Insurance) is private insurance that covers the "gaps" in Original Medicare — primarily the 20% coinsurance, deductibles, and hospital costs. Plan G is the most comprehensive plan available to new enrollees in 2026, typically costing $100–$200/month.
Whether Medigap makes financial sense depends on your expected healthcare usage. Use our Medigap cost calculator to estimate your break-even point.
