Healthcare is consistently one of the largest expenses retirees face. Even with Medicare covering a significant share of medical costs, the premiums, deductibles, coinsurance, and services that fall outside Medicare's scope can add up to thousands of dollars each year. Planning ahead and understanding what you are likely to spend can help you avoid financial surprises and make confident decisions about your coverage.
This guide walks through the major Medicare cost categories for 2026, shows what different retirees may expect to pay annually, and offers practical strategies to keep spending manageable.
The Baseline: What Original Medicare Costs in 2026
Original Medicare consists of Part A (hospital insurance) and Part B (medical insurance). Together, they form the foundation of coverage for most retirees. Here is what each part costs in 2026.
Part A (Hospital Insurance)
- Premium: Most people pay $0 per month for Part A because they (or a spouse) earned at least 40 work credits through Medicare-taxed employment. If you have 30 to 39 credits, you pay $311 per month. With fewer than 30 credits, the full premium is $565 per month.
- Inpatient hospital deductible: $1,736 per benefit period — this resets each time you start a new benefit period, not on a calendar-year basis.
- Hospital coinsurance: $0 per day for days 1 through 60. $434 per day for days 61 through 90. $868 per day for lifetime reserve days (you have 60 of these over your lifetime).
- Skilled nursing facility coinsurance: $0 for days 1 through 20 (after a qualifying hospital stay), then $217 per day for days 21 through 100.
Part B (Medical Insurance)
- Premium: $203.90 per month ($2,446.80 per year) for most beneficiaries, deducted from your Social Security check.
- Annual deductible: $257 before Medicare starts paying its share.
- Coinsurance: You pay 20% of the Medicare-approved amount for most Part B services. There is no annual cap on this 20%, which is one reason many retirees add supplemental coverage.
Part D (Prescription Drug Coverage)
- Premium: Varies by plan. The national base beneficiary premium is approximately $36.78 per month in 2026, though actual premiums depend on the plan you choose.
- Deductible: Up to $615 per year, depending on the plan.
- Out-of-pocket cap: $2,100 — once your true out-of-pocket drug spending reaches this amount, you pay nothing further for covered prescriptions for the rest of the year.

Adding Supplemental Coverage: Medigap vs. Medicare Advantage
Original Medicare leaves gaps — most notably the uncapped 20% Part B coinsurance and the per-benefit-period hospital deductible. Retirees generally choose one of two paths to manage that exposure.
Medigap (Medicare Supplement Insurance)
Medigap policies are sold by private insurers and cover some or all of the cost-sharing that Original Medicare does not. Plan G is one of the most commonly selected options. It generally covers the Part A deductible, Part B coinsurance, skilled nursing coinsurance, and other gaps — leaving you responsible only for the $257 annual Part B deductible.
- Monthly premiums typically range from $100 to $300 or more, depending on your age, location, gender, and the insurer.
- You keep Original Medicare and can see any provider nationwide that accepts Medicare.
- You still need a separate Part D plan for prescription drug coverage.
Medicare Advantage (Part C)
Medicare Advantage plans are offered by private insurers as an alternative to Original Medicare. Many plans are available with $0 additional premiums beyond your Part B premium and may include prescription drug coverage, dental, vision, and hearing benefits.
- Instead of coinsurance-free coverage after meeting a deductible, you typically pay copays or coinsurance per service (for example, a copay for each doctor visit or a percentage for outpatient surgery).
- In 2026, the maximum out-of-pocket (MOOP) limit for in-network services is $9,250. Your plan's actual MOOP may be lower.
- You generally must use providers within the plan's network (HMO) or pay more for out-of-network care (PPO).

The IRMAA Factor: Higher Earners Pay More
If your modified adjusted gross income (MAGI) exceeds certain thresholds, you will pay an Income-Related Monthly Adjustment Amount (IRMAA) surcharge on top of the standard Part B and Part D premiums. IRMAA is based on the tax return from two years prior.
Here is how it can affect costs:
- Standard income (at or below the threshold): You pay the standard $203.90 per month for Part B.
- Single filer with $150,000 MAGI: You may pay approximately $405.80 per month for Part B, plus a Part D surcharge of roughly $37.50 per month — adding over $2,800 per year in extra premiums.
IRMAA brackets rise with income, and the highest earners may pay significantly more. Even a one-time income spike — such as a Roth conversion, sale of property, or large capital gain — can trigger a higher bracket for a year.
For the complete bracket table and strategies to manage IRMAA, see our guide to Medicare income-based surcharges.
Typical Annual Cost Scenarios
Every retiree's situation is different, but the following rough estimates can help you frame your budget. All figures assume standard income (no IRMAA) and include Part B premiums.
| Scenario | Coverage Path | Estimated Annual Cost | |---|---|---| | Healthy retiree, minimal care | Original Medicare + Medigap Plan G + standalone Part D | $5,000 – $7,000 | | Moderate healthcare user | Medicare Advantage (with drug coverage) | $3,000 – $5,000 | | High-use retiree, frequent services | Medicare Advantage (approaching MOOP) | $5,000 – $12,000 |
How these estimates break down:
- Healthy retiree on Original Medicare + Medigap G: Part B premium (~$2,447) + Medigap premium (~$1,500–$3,000) + Part D premium (~$440) + Part B deductible ($257) = roughly $5,000 to $7,000 per year. Actual medical out-of-pocket costs may be very low because Medigap covers most cost-sharing.
- Moderate user on Medicare Advantage: Part B premium (~$2,447) + $0 plan premium + copays for several doctor visits, a few specialist appointments, and prescriptions = roughly $3,000 to $5,000 per year.
- High-use retiree on Medicare Advantage: Part B premium (~$2,447) + copays and coinsurance that approach the plan's MOOP limit = roughly $5,000 to $12,000 per year, depending on the plan's out-of-pocket maximum and services used.
These are general estimates. Your actual costs will depend on the specific plans available in your area, your health conditions, and the prescriptions you take.
Costs Medicare Does Not Cover
When budgeting for retirement healthcare, it is important to account for services that Medicare generally does not cover, including:
- Dental care — routine cleanings, fillings, extractions, and dentures
- Vision care — routine eye exams, eyeglasses, and contact lenses
- Hearing aids and routine hearing exams
- Long-term care — custodial or personal care in a nursing home or at home
- Most care received outside the United States
- Cosmetic surgery
Some Medicare Advantage plans include dental, vision, and hearing benefits as part of their coverage package. If these services are important to you, that may be a factor in choosing your coverage path. However, even with those added benefits, long-term care remains a major gap that Medicare does not address.
Strategies to Manage Medicare Costs
There are several practical steps you can take to keep your Medicare spending as low as possible.
- Review your plans every year during the Annual Enrollment Period (AEP). Plan premiums, formularies, networks, and benefits change annually. A plan that was the best fit last year may not be the best fit this year. AEP runs from October 15 through December 7 each year.
- Check whether you qualify for Extra Help (Low-Income Subsidy). This federal program can significantly reduce your Part D premiums, deductibles, and copayments if your income and resources fall below certain limits. Learn more in our guide to Extra Help and the Low-Income Subsidy.
- Look into Medicare Savings Programs. If you have limited income, your state may help pay your Part B premium, deductibles, and coinsurance. See our Medicare Savings Programs overview.
- Consider contributing to a Health Savings Account (HSA) before enrolling in Medicare. HSA funds can be used tax-free for qualified medical expenses in retirement, including Medicare premiums. However, you can no longer contribute to an HSA once you are enrolled in any part of Medicare. Read our guide to HSA rules and Medicare for details on planning ahead.
- Use the Medicare Prescription Payment Plan. If you face high upfront drug costs, this option lets you spread your Part D out-of-pocket expenses into predictable monthly payments throughout the year. Learn how it works in our Medicare Prescription Payment Plan guide.
- Contact your State Health Insurance Assistance Program (SHIP). SHIP counselors provide free, unbiased help with Medicare questions — including comparing plans, understanding bills, and identifying programs you may qualify for. You can find your local SHIP by visiting Medicare.gov or calling 1-800-MEDICARE (1-800-633-4227).
Planning Over a Retirement Lifetime
Medicare costs are not a one-time calculation. Premiums and cost-sharing amounts generally increase each year, and your healthcare needs are likely to grow as you age. According to Fidelity Investments, according to a 2024 Fidelity Investments estimate, a 65-year-old may need approximately $165,000 to cover healthcare expenses throughout retirement (for a single person). Couples may need roughly double that amount.
Several factors influence your lifetime healthcare costs:
- Age and health status — healthcare utilization tends to increase over time
- Inflation in premiums and cost-sharing — Medicare costs have historically risen faster than general inflation
- Prescription drug needs — medication costs can change significantly as health conditions evolve
- Supplemental coverage choices — Medigap premiums generally increase with age, while Medicare Advantage plan structures may shift from year to year
- Long-term care — if needed, this can represent the single largest healthcare expense in retirement and is not covered by Medicare
Building healthcare costs into your broader retirement plan — alongside housing, food, taxes, and other essentials — helps ensure you are prepared for what may be one of your largest ongoing expenses.
The Bottom Line
Medicare provides valuable coverage, but it is not free. Between Part B premiums, supplemental coverage, prescription drugs, and services Medicare does not cover, retirees may spend anywhere from a few thousand dollars to well over ten thousand dollars per year on healthcare — and those costs generally rise over time.
The most effective approach is to understand the cost structure, choose a coverage path that fits your health needs and budget, and revisit your plan annually. Programs like Extra Help, Medicare Savings Programs, and SHIP counseling are available at no cost to help you navigate your options.
