"$0 premium" is the headline you'll see on almost every Medicare Advantage ad. It's also the line that confuses the most people — because $0 isn't actually what you pay.
Here's the honest 2026 breakdown of what Medicare Advantage really costs, including the line items most ads leave out.
The Average Medicare Advantage Premium in 2026
The average monthly premium for a Medicare Advantage plan in 2026 is about $14 per month, and roughly three out of four people live in an area with at least one $0-premium plan available. That's the number most ads lean on.
The catch: the $14 figure is only the plan's premium. You still owe your Part B premium to Medicare every month — and that's where most of your monthly cost actually lives.
You Still Pay Your Part B Premium
To enroll in any Medicare Advantage plan, you must already be enrolled in Original Medicare Parts A and B. That means you keep paying your Part B premium — $202.90/month at the standard rate in 2026, more if you fall into an IRMAA income bracket.
So a "$0 premium" Medicare Advantage plan really means: $0 to the plan, plus $202.90+ to Medicare for Part B. That's your true monthly floor.
The Real 2026 Cost Stack
| Cost Line | What You Pay in 2026 |
|---|---|
| Part B Premium (always owed) | $202.90/mo standard — up to $689.90/mo at top IRMAA bracket |
| Plan Premium | Avg $14/mo; many $0 plans available |
| Plan Deductible | $0–$500 depending on plan |
| Primary Care Copay | Typically $0–$15 per visit |
| Specialist Copay | Typically $35–$55 per visit |
| Drug Coverage (if included) | Usually bundled; deductible up to $615 |
| In-Network OOP Max | Up to $9,250 in 2026 |
| Combined In + Out-of-Network OOP Max (PPO) | Up to $13,900 in 2026 |
The Out-of-Pocket Maximum: The Number That Actually Matters
Medicare Advantage's most underrated feature is the annual out-of-pocket maximum. Once you hit it, the plan covers 100% of your in-network Part A and Part B care for the rest of the year. Original Medicare has no such cap.
For 2026, the federal limit is $9,250 in-network for HMO and PPO plans, though most plans set theirs lower (the industry average sits closer to $5,300). PPO plans have a separate combined in-and-out-of-network max — up to $13,900.
Where the "Cheap" Plans Can Get Expensive
A $0-premium plan is genuinely cheap if you stay healthy and in-network. It can get expensive fast if any of these happen:
- A specialist isn't in your network. An out-of-network visit on an HMO can be 100% your cost.
- You need a hospital stay. Daily copays of $295–$400 for the first 5–7 days are common.
- You travel. Most plans only cover routine care in your home service area.
- A new drug gets moved to a higher tier. Formularies change every January.
Meet Raymond — Why $0 Wasn't Free
Raymond, 71, picked the $0-premium plan a neighbor recommended. The first year was easy — he stayed in-network and barely used the plan.
The second year he needed knee surgery. With hospital copays, specialist visits, and rehab, he hit nearly $5,800 in out-of-pocket costs before the plan's max kicked in — plus $202.90 every month for Part B.
The lesson isn't that the plan was bad. It's that "premium" is only one number. You have to look at copays, hospital stays, and the OOP max together.
Medicare Advantage vs. Original Medicare: True Monthly Cost
| Scenario | Original Medicare + Medigap G + Part D | Medicare Advantage (avg) |
|---|---|---|
| Monthly cost (healthy year) | ~$420/mo ($202.90 B + ~$150 Medigap + ~$65 Part D) | ~$217/mo ($202.90 B + $14 plan) |
| Cost in a high-use year | Same as above — Medigap pays the gaps | Up to OOP max (~$5,300 avg) |
| Provider freedom | Any provider that accepts Medicare | In-network only (HMO) or in/out (PPO) |
| Annual review needed? | Rarely | Yes — every fall during AEP |

How to Estimate Your True 2026 Cost
- Start with $202.90/month for Part B (or more if you're in an IRMAA bracket).
- Add the plan's monthly premium.
- Add the expected copays for the doctors and specialists you see in a typical year.
- Confirm your medications are on the formulary at a reasonable tier.
- Check the plan's out-of-pocket max — that's your worst-case ceiling.
