The 2026 Medicare Cost Components

Medicare costs come from four main sources: Part B premiums (the main monthly charge), IRMAA surcharges for higher incomes, supplemental coverage (Medigap or Medicare Advantage), and Part D drug coverage. Understanding each component lets you accurately budget for healthcare in retirement.

Part B Premium: $185.00/Month Standard

The standard 2026 Part B premium is $185.00/month ($2,220/year) per person. This covers doctor visits, outpatient services, and preventive care. It's automatically deducted from your Social Security check if you receive benefits; otherwise paid directly to Medicare. This is the baseline everyone starts from — but higher incomes pay more through IRMAA.

IRMAA: When Income Raises Your Premium

Medicare uses your income from two years prior to determine if you owe IRMAA surcharges. In 2026, surcharges begin at $106,000 MAGI (single) or $212,000 (married filing jointly). The income brackets and monthly costs per person:

Single Income Married Income Part B/mo Annual / Person
≤$106,000≤$212,000$185.00$2,220
$106K–$133K$212K–$266K$259.00$3,108
$133K–$167K$266K–$334K$370.00$4,440
$167K–$200K$334K–$400K$481.10$5,773
>$500K>$750K$628.90$7,547

IRMAA also applies to Part D premiums, adding $13.70–$85.80/month depending on income tier. For a couple where both individuals are at the second IRMAA tier ($259/month Part B each), they pay $6,216/year in Part B alone — vs. $4,440 for the same couple without IRMAA.

Medigap: Filling the Gaps in Original Medicare

Original Medicare pays 80% of approved costs after deductibles. The 20% coinsurance has no annual cap — a $200,000 medical event could leave you with $40,000 in bills. Medigap closes most of these gaps. The two most popular plans in 2026:

  • Plan G: Covers everything except the Part B annual deductible ($257). Monthly premiums range from $130 (age 65) to $250+ (age 75+) depending on insurer and state. Total annual cost at 65: approximately $1,800–$2,500/year in premiums + $257 deductible = ~$2,000–$2,800/year for essentially unlimited coverage.
  • Plan N: Similar to Plan G but you pay $20 copay for doctor visits and $50 for ER visits. Lower premium — roughly $100–$180/month. Better value if you have few doctor visits; similar to Plan G if you use it frequently.

Medigap premiums increase with age. A Plan G that costs $160/month at 65 may cost $240/month at 75 with the same insurer. Shopping plans annually (after the guaranteed issue period) can save money.

Part D: Drug Coverage

Part D average premium is $55–$65/month in 2026. The annual deductible is $590. Since 2025, out-of-pocket drug costs are capped at $2,000/year under the Inflation Reduction Act — a major improvement. Higher-income beneficiaries pay IRMAA surcharges on Part D as well (adding $13.70–$85.80/month).

Total Annual Medicare Costs: Real Examples

2026 Annual Medicare Cost Estimates (per person)
Scenario Annual Premium Cost
Standard income, Medicare Advantage ($0 premium) + standard Part D$840–$1,860
Standard income, Original Medicare + Medigap Plan N + standard Part D$3,600–$5,000
Standard income, Original Medicare + Medigap Plan G + standard Part D$4,200–$6,000
IRMAA Tier 2 ($133K–$167K single), Plan G + standard Part D$6,700–$8,200
IRMAA Tier 4 ($200K–$500K single), Plan G + standard Part D$10,500–$12,000

Out-of-pocket costs add $1,000–$4,000/year on top of premiums for doctor visits, dental, vision, and prescriptions beyond the formulary. For a couple, multiply individual estimates by two.

IRMAA planning tip: IRMAA is based on income from 2 years prior. In the year you retire, your income drops — but Medicare uses your pre-retirement income. You can appeal IRMAA (Form SSA-44) if you had a "life-changing event" such as retirement. Get your appeal in quickly to reduce the first year's surcharge. Also, Roth IRA withdrawals don't count as MAGI — building Roth assets reduces future IRMAA exposure.

To fund these Medicare costs tax-efficiently, your HSA balance can cover all Medicare premiums tax-free after age 65. See using your HSA as a retirement account for the strategy. For a full Medicare primer, read what is Medicare.

How can I reduce my Medicare costs?

Strategies: (1) Keep 2-years-prior income below IRMAA thresholds — use Roth withdrawals (not counted as MAGI) in high-income years. (2) Appeal IRMAA if retired and income dropped (Form SSA-44). (3) Compare Medigap vs. Medicare Advantage based on your expected healthcare use. (4) Use HSA funds for Medicare premiums tax-free. (5) Shop Part D plans annually during open enrollment (Oct 15–Dec 7).

Can HSA funds pay for Medicare?

Yes. After age 65, HSA withdrawals are tax-free for Medicare Part B, Part D, and Medigap premiums. Medicare Advantage premiums also qualify. This makes HSA funds one of the most efficient ways to fund Medicare costs — they go in pre-tax and come out tax-free for healthcare in retirement.
