How Much Does Medicare Cost in 2025? The Real Numbers

Medicare is not free. Most people understand that at a high level, but few know the specific numbers until a bill shows up. Understanding what Medicare actually costs — and where the exposure is — helps you plan your retirement finances far more accurately.

Here are the real 2025 numbers, explained clearly.

Part A (Hospital Insurance) Costs

Most people — those who worked and paid Medicare taxes for at least 10 years — pay no monthly premium for Part A. That's roughly 99% of beneficiaries.

But Part A still has cost-sharing:

• Inpatient hospital deductible: $1,676 per benefit period in 2025. Note: this is per benefit period, not per year. If you're hospitalized, discharged, and then readmitted after 60 days, you could owe this deductible again.
• Hospital coinsurance:
  • Days 1–60: $0 (deductible already covers this)
  • Days 61–90: $419/day
  • Days 91+: $838/day ("lifetime reserve days" — you have 60 of these total)
• Skilled nursing facility coinsurance:
  • Days 1–20: $0
  • Days 21–100: $209.50/day
  • Beyond 100 days: 100% of costs

This is one area where Original Medicare's lack of an out-of-pocket cap becomes very tangible for people with extended hospital stays.

Part B (Medical Insurance) Costs

• Standard monthly premium: $185.00 in 2025
• Annual deductible: $257 in 2025
• Coinsurance: After the deductible, Medicare typically pays 80% of approved amounts; you pay the remaining 20% with no annual cap under Original Medicare alone

The 20% coinsurance is often the biggest financial surprise for new Medicare beneficiaries. A $100,000 surgery leaves you with a $20,000 bill under Original Medicare alone — unless you have supplemental coverage.

IRMAA: Income-Related Monthly Adjustment Amount

If your income is above certain thresholds, you'll pay more than the standard Part B premium. This is called IRMAA (Income-Related Monthly Adjustment Amount), and it also applies to Part D.

Medicare uses your tax return from two years ago to determine IRMAA. In 2025, the income thresholds and surcharges are:

If you recently retired and your income has dropped significantly, you can appeal your IRMAA using form SSA-44, which allows Medicare to use more recent income data.

Part D (Prescription Drug) Costs

Part D premiums vary by plan and location — there's no single standard premium. The national base beneficiary premium in 2025 is approximately $36.78/month, but individual plan premiums range widely.

Key 2025 changes to Part D:

• Annual out-of-pocket cap: In 2025, once your total drug costs (what you and the plan together pay) reach $2,000, you pay nothing more for covered drugs for the rest of the year. This is a major change from prior years.
• Monthly payment option: Under the Medicare Prescription Payment Plan, you can spread Part D cost-sharing across monthly payments throughout the year.

Medigap: Filling the Gaps

Medigap (Medicare Supplement Insurance) policies are sold by private insurers to cover the costs that Original Medicare leaves behind — deductibles, coinsurance, and copays.

Standardized Medigap plans are labeled by letter (Plan G and Plan N are the most popular today for new enrollees). Monthly premiums vary based on the plan, your age, your location, and the insurer — typically ranging from around $100 to $300+ per month.

Plan G covers nearly everything Original Medicare doesn't, including the Part A deductible, hospital coinsurance, and foreign travel emergency (up to plan limits). You pay only the Part B deductible ($257 in 2025) out of pocket.

Plan N costs less than Plan G but has some copays — up to $20 for doctor visits, up to $50 for emergency room visits that don't result in admission.

Texas Medicaid and Dual Eligibility

For Texans with limited income and resources, Medicaid can work alongside Medicare to reduce or eliminate out-of-pocket costs. People who qualify for both Medicare and Medicaid are called "dual eligible" beneficiaries.

Texas has several Medicaid programs that may help pay Medicare premiums, deductibles, and coinsurance:

• QMB (Qualified Medicare Beneficiary): Covers Part A and B premiums, deductibles, and coinsurance
• SLMB (Specified Low-Income Medicare Beneficiary): Covers Part B premium only
• QI (Qualifying Individual): Covers Part B premium only (limited slots, first-come basis)

Eligibility is based on income and asset limits. Contact Texas Health and Human Services at 2-1-1 or your local SHIP counselor to see if you qualify.

The Bottom Line on Medicare Costs

For most people on Original Medicare without supplemental coverage, the main cost exposure areas are:

• The Part B 20% coinsurance (no cap)
• The per-benefit-period hospital deductible
• Prescription drug costs under Part D

For people with Medicare Advantage, costs are more structured — with copays for services and an annual out-of-pocket maximum — but your exposure depends entirely on the specific plan you choose.

Knowing these numbers upfront lets you make smarter decisions about supplemental coverage and budget appropriately for healthcare in retirement.
