How much does Medicare actually cost in 2026?
Last reviewed May 9, 20263 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
There is no single Medicare price tag. There is a base premium that almost everyone pays, a means-tested surcharge that one in five enrollees pays on top, and a stack of optional add-ons that determine what you actually owe. Here's the math, in the order the dollars arrive.
The base, Part A and Part B
Part A is $0/mo if you (or a spouse) worked at least 40 quarters paying Medicare taxes. That's roughly 99% of enrollees. The 1% who didn't can buy in at $311 or $565/mo depending on their work history.
Part B is $202.90/mo standard in 2026. There is also a $283 annual deductible. After the deductible, Part B pays 80% of approved charges; you owe the remaining 20%, with no annual cap, which is the structural reason most Original Medicare enrollees add Medigap.
The surcharge, IRMAA
If your modified adjusted gross income from 2024 was above $109,000 (individual) or $218,000 (joint), you'll pay more. The Income-Related Monthly Adjustment Amount adds to both Part B and Part D across six tiers.
If a qualifying life event has dropped your income since 2024, you can appeal with SSA-44. We cover the appeal in a separate article.

The add-ons
Beyond A + B, three optional pieces stack on top depending on which path you take:
- Part D (drugs), $0 to $60/mo depending on plan and formulary. Required if you don't have credible drug coverage from another source, or you'll pay a 1%/month late-enrollment penalty when you eventually enroll.
- Medigap supplement, $100 to $250/mo depending on letter plan, state, age, and (in most states) tobacco use. Pairs only with Original Medicare. Plan G is the most common new purchase today; Plan N runs about 15% cheaper.
- Medicare Advantage, often $0/mo on top of Part B, but you accept a network and prior-authorization rules. Many Advantage plans bundle Part D, so it replaces the D premium rather than stacking with it.
Whatever path you take, Part D drug spending has its own ceiling in 2026, worth knowing before you compare plans.
Two realistic scenarios
| Path | Monthly cost | Worst-case year |
|---|---|---|
| Original + Plan G + Part D | ~$395/mo | ~$4,700 |
| Medicare Advantage (HMO, $0 premium) | $202.90/mo | ~$10,700 |

The bottom row's premium is lower but its worst-case ceiling is much higher. The right answer depends on which kind of risk you'd rather hold: predictable monthly cost, or low monthly cost with a higher tail.
Common questions about Medicare cost
Quick answers, fast .

Why is Part B going up every year?
By law, Part B premiums cover roughly 25% of program costs; the federal government covers the rest. As healthcare spending rises, so does the premium. The 2026 standard premium of $202.90 reflects the typical year-over-year adjustment tied to program costs.
Is Part A really free?
Yes, the monthly premium is $0 if you or your spouse worked at least 40 quarters paying Medicare taxes. You still owe a $1,736 inpatient deductible per benefit period, and Part A doesn't cover long-term custodial care.
How does the Part D late-enrollment penalty work?
1% of the national base beneficiary premium for every month you went without credible drug coverage after becoming eligible, added to your Part D premium for as long as you have Part D. A 12-month gap is 12%; a 5-year gap is 60%.
Can I switch from Advantage back to Original?
Yes, during AEP (October 15 to December 7) or the Medicare Advantage Open Enrollment Period (January 1 to March 31). The catch: outside your initial Medigap Open Enrollment window, carriers can underwrite your Medigap policy or deny you, depending on your state.
Does the $202.90 figure include anything else?
No. $202.90 is just Part B. You'll still pay separately for Part D (if you carry it), Medigap (if you carry it), or out-of-pocket costs on a Medicare Advantage plan. The "all-in" monthly cost for a typical Original + Medigap + Part D combo runs $300 to $450.
