What Medicare Really Costs at 65 (Real Numbers)

If you’re turning 65 and trying to figure out what Medicare will actually cost you, you’ve come to the right place. I’m going to break down the real numbers for 2026 – not the marketing fluff, but the actual dollars and cents you’ll be paying for each Medicare option.

The Base Costs Everyone Pays

Let’s start with what everyone on Medicare pays, regardless of which path you choose.

Medicare Part B Premium

You’ll pay $202.90 per month in 2026 for Medicare Part B. This gets deducted directly from your Social Security check, or if you’re not collecting Social Security yet, you’ll pay it quarterly.

Here’s where it gets tricky: if your income is above certain thresholds, you’ll pay IRMAA (Income-Related Monthly Adjustment Amount) surcharges on top of the base premium. The government looks back two years at your tax returns to determine this. So for 2026, they’re looking at your 2024 income.

Medicare Part A Premium

Most people pay $0 per month for Medicare Part A because they’ve worked and paid Medicare taxes for at least 10 years (40 quarters). If you haven’t worked long enough, you’ll pay premiums for Part A, but this affects very few people.

Medicare Part B Deductible

You’ll pay a $283 deductible each year before Medicare kicks in. After you meet this deductible, Medicare pays 80% of outpatient services, and you pay the remaining 20%. Important note: Medicare Supplement Plan G and Plan N do not cover this deductible.

Agent Tip

I see people get confused about IRMAA all the time. If you had a high-income year two years ago but expect lower income in retirement, you can appeal the IRMAA determination. I help clients with this process regularly.

Your Medicare Plan Options and Costs

Now let’s look at your three main options and what each will actually cost you.

Option 1: Original Medicare A & B Only

This is rarely a good choice. With Original Medicare alone, you’d pay:

• The Part A deductible: $1,736 per benefit period
• The Part B deductible: $283 annually
• 20% of all outpatient services with no limit

The big problem? There’s no out-of-pocket maximum. Your costs could be unlimited, which is why almost everyone chooses additional coverage.

Option 2: Medicare Supplement (Medigap) Plans

These plans work alongside Original Medicare to cover your gaps. Here are the most popular options:

Plan G (Most Popular)

With Plan G, you pay the $283 Part B deductible each year, then Plan G covers all other Medicare-approved costs. Monthly premiums typically range from $100-$200 depending on your state, age, and insurance company.

The major advantage? No networks. You can see any doctor nationwide who accepts Medicare, which is about 95% of all doctors.

Plan N

Plan N offers lower premiums than Plan G – typically $80-$150 per month – but includes some cost-sharing:

• $0-$20 co-pays for office visits
• $50 emergency room co-pay (waived if you’re admitted)
• You might pay excess charges if you see doctors who don’t accept Medicare assignment

High Deductible Plan G

This option has much lower monthly premiums (typically under $100/month) but requires you to pay $2,950 out-of-pocket before the plan kicks in. Once you meet the deductible, it works exactly like regular Plan G.

Option 3: Medicare Advantage (Part C)

Medicare Advantage plans often have $0 or very low monthly premiums and typically include prescription drug coverage, plus extras like dental, vision, hearing aids, and gym memberships.

However, you’ll pay as you go with co-pays and co-insurance for services. Medicare Advantage plans also have out-of-pocket limits ranging from $7,000-$9,000 per year.

The trade-off? You’re restricted to the plan’s network of doctors and hospitals.

Medicare Part D Prescription Drug Coverage

If you choose Original Medicare with a supplement plan, you’ll need separate Part D prescription drug coverage. Medicare Advantage plans typically include drug coverage.

Part D plan premiums range from $0 to about $170 per month. In 2026, the maximum out-of-pocket limit for Part D is $2,100 for co-pays and co-insurance on covered drugs.

Important: Your monthly premiums don’t count toward this limit – only what you pay at the pharmacy counter counts.

Agent Tip

Many people think they don’t need Part D if they don’t take medications. Big mistake. If you don’t enroll when first eligible and need coverage later, you’ll pay late enrollment penalties for life. The penalty is 1% of the national base premium for each month you were without coverage.

Real Cost Breakdown for Age 65 in 2026

Here’s what you can expect to pay monthly when you turn 65:

Plan Type	Monthly Premium	Annual Out-of-Pocket Risk
Part B + Plan G + Part D	$250-$400	$283 + Part D costs
Part B + Plan N + Part D	$200-$320	$283 + co-pays + Part D costs
Part B + High Deductible Plan G + Part D	$150-$250	$2,950 + Part D costs
Medicare Advantage (includes drugs)	$22.90-$100	$7,000-$9,000

The Supplement Route vs. Advantage Route

Here’s how the two main paths compare:

Supplement Route (Plan G + Drug Plan)

• Part B: $202.90/month
• Plan G: $100-$200/month
• Drug plan: $100-$150/month
• Higher monthly premiums, lower out-of-pocket costs, full doctor choice nationwide

Advantage Route (Part C)

• Part B: $202.90/month
• Part C plan: Often $0/month
• Pay-as-you-go with co-pays and co-insurance
• Lower monthly premiums, higher potential out-of-pocket costs, network restrictions

The choice often comes down to your budget preference: predictable higher monthly costs versus lower monthly costs but potentially higher medical bills.

Important Considerations

Remember that the $202.90 Part B premium applies regardless of whether you choose a supplement or Advantage plan. If you’re subject to IRMAA, those surcharges apply to both your Part B premium and your Part D premium.

Also, timing matters significantly when you first become eligible for Medicare. You have guaranteed issue rights for supplement plans during your first six months on Medicare Part B, regardless of your health.

Frequently Asked Questions

Do I have to pay the Part B premium even with Medicare Advantage?

Yes, you must pay the Medicare Part B premium regardless of which plan type you choose. Medicare Advantage plans don’t replace this requirement – they work alongside Original Medicare.

Can I switch from Medicare Advantage to a supplement plan later?

You can switch during Medicare’s Annual Open Enrollment (October 15 – December 7), but switching to a supplement plan after your initial enrollment period requires medical underwriting in most states.

What happens if I don’t sign up for Part D when I’m first eligible?

You’ll pay a late enrollment penalty of 1% of the national base premium for each month you were without creditable drug coverage. This penalty continues for as long as you have Part D coverage.

Are the premium costs the same in every state?

Part B premiums are the same nationwide, but supplement plan premiums vary significantly by state, insurance company, age, and sometimes gender. Some states like California have additional consumer protections like the Birthday Rule that can help you switch plans.

What’s the difference between Plan G and Plan N costs over time?

Plan N typically has lower monthly premiums but includes co-pays for office visits and emergency rooms. Whether Plan G or Plan N costs less depends on how often you visit doctors and your risk tolerance for co-pays.
