Here's the honest answer: there's no single national Medigap price. Premiums shift based on the plan letter you choose, the insurer you pick, your state and ZIP code, your age, whether you use tobacco, when you enroll, and how the insurer calculates rates.
This guide breaks down realistic 2026 pricing ranges, what your premium actually covers, the variables that move your quote up or down, and how to build a Medicare budget that won't surprise you later.
Key Takeaways
- Medigap premiums range from about $50/month for high-deductible options to $270+/month for comprehensive plans
- Same lettered plans share identical core benefits, but premiums differ widely by insurer and location
- Plan G, Plan N, and high-deductible plans each balance monthly premium against out-of-pocket risk
- Part B, Part D, and uncovered services add to total Medicare costs beyond your Medigap premium
How Much Does Medigap Insurance Cost? (Pricing Overview)
Ask ten people what Medigap costs and you'll get ten different answers, because published averages blend different ages, plan types, states, and tobacco categories into one number. A personalized quote based on your ZIP code and birthdate tells you far more than any national figure.
That said, a benchmark helps set expectations. KFF's most recent nationwide data puts the average Medigap premium at $217 per month across existing policyholders in 2023 — not a fresh 2026 quote for a new applicant.
That same analysis found Plan G averaging $164/month, with state averages ranging from $191 in Alaska to $267 in New York.
Illustrative 2026 Cost Tiers
State insurance department guides from 2026 show how premiums stack up by plan type. These are real filed examples, not universal prices:
| Plan Type | Example 2026 Monthly Premium | What You're Trading Off |
|---|---|---|
| High-deductible G or F | $50–$100 | Lower premium, but you pay costs upfront until a set threshold |
| Plan K | $111–$313 | Partial cost-sharing on many services |
| Plan L | $212–$244 | Less cost-sharing than K, still not full coverage |
| Plan N | $167–$189 | Small office/ER copays, no excess-charge coverage |
| Standard Plan G | $212–$277 | Comprehensive coverage except the Part B deductible |
What your Medigap premium doesn't include:
- Medicare Part B premium
- Prescription drugs
- Routine dental or vision care
- Hearing aids
- Long-term care
Those are separate line items in your overall Medicare budget, which we'll break down later in this article.
Factors That Affect Medigap Premiums and Total Costs
Medigap benefits are standardized by the federal government, but pricing is not. A Plan G sold by one insurer covers the same things as a Plan G sold by another — the difference is entirely in premium and service.
Plan Type and Coverage Level
More comprehensive plans mean higher premiums but fewer surprises. Plans with built-in cost-sharing (K, L) or a high deductible (high-deductible G or F) lower your monthly bill in exchange for more potential out-of-pocket spending.
Plans C and F are generally unavailable to anyone who became eligible for Medicare on or after January 1, 2020. If you were eligible before that date and never enrolled, you may still qualify — but new beneficiaries won't have access to these two plans.
Age, Health, Tobacco Use, and Enrollment Timing
Several personal factors shape your quote:
- Age: Often the biggest variable, especially under attained-age pricing
- Tobacco use: Many insurers charge higher premiums for smokers
- Enrollment timing: Applying in your protected window avoids medical underwriting
- Health history: Matters only outside a guaranteed-issue period
If you're under 65 and qualify for Medicare through disability or end-stage renal disease (ESRD), Medigap protections vary by state. The federal guaranteed-issue right generally applies at 65. As of 2022:
- 36 states required at least one Medigap plan for under-65 beneficiaries during an initial window
- 26 of those extended that requirement to people with ESRD
Check your state's current rules—this landscape still shifts.
Location and Insurer
Premiums vary by state, county, and even ZIP code because local healthcare costs and state regulations differ. Comparing multiple insurers for the same plan letter can save over $50 a month for identical coverage—but only quotes for your ZIP code apply.
Rating Method and Future Increases
Insurers price Medigap policies using one of three methods:
- Community-rated — everyone pays the same regardless of age
- Issue-age-rated — your starting price locks in based on your age when you buy, and doesn't increase just because you get older
- Attained-age-rated — premiums rise as you age, typically the lowest starting price but the highest long-term cost
Even community-rated and issue-age-rated policies can still see annual increases tied to inflation or claims experience. As one real example, Mississippi's insurance regulator approved a 15% rate increase for a specific State Farm Medigap policy series effective June 1, 2026—so "not age-based" still does not mean rates never rise.
Cost Breakdown of Medigap Insurance
Your true annual Medicare budget includes far more than the number on your Medigap bill. Here's how the pieces fit together.
Monthly Medigap Premium
Take your quoted monthly rate and multiply by 12 to see the annual commitment. A $220/month Plan G premium, for example, totals $2,640 per year before any care costs. If you're quoted a high-deductible plan, confirm that upfront so you're not comparing apples to oranges.
Medicare Premiums and Prescription Coverage
Medigap doesn't replace Part B — it works alongside it. The standard 2026 Part B premium is $202.90 per month, with higher-income beneficiaries paying surcharges on top. That's a separate bill from your Medigap premium, and it's mandatory for anyone enrolled in Part B.
Medigap also doesn't include prescription drug coverage. Most beneficiaries pair it with a standalone Part D plan, which has its own monthly premium and drug costs.
Medigap plus Part D is a common setup for people who want broad doctor access and drug coverage without Medicare Advantage.
Deductibles, Copayments, and Coinsurance
Even with Medigap, some costs remain your responsibility:
- Plan G: You still pay the annual Part B deductible ($283 in 2026)
- Plan N: Up to $20 for some office visits and up to $50 for ER visits (waived if admitted)
- Plans K and L: Cover about 50% and 75% of costs until you reach the annual out-of-pocket limit ($8,000 for K and $4,000 for L in 2026)
- High-deductible G or F: You pay up to $2,950 in covered costs before the plan pays
Uncovered Services and Optional Coverage
Medigap generally won't touch these expenses:
- Routine dental, vision, and hearing aids
- Long-term care
- Private-duty nursing
- Most prescription drugs (covered separately through Part D)
Some carriers add discounts or perks (sometimes called "innovative benefits"), such as a gym membership deal. Those are extras, not insurance coverage or financial protection.
Low-Cost vs. Higher-Cost Medigap Options — What's the Difference?
Comparing plans by premium alone misses the point. The real comparison is total expected cost: premium plus likely out-of-pocket spending, weighed against your healthcare usage and risk tolerance.
Lower-Premium Options
Plans like Plan N, Plan K, Plan L, or high-deductible Plan G might fit you if:
- Generally healthy with few expected doctor visits
- Emergency savings ready for unexpected copayments
- Willing to accept some cost uncertainty for a lower monthly bill
Before committing, estimate your realistic healthcare use and read the plan's annual cost-sharing rules closely. A cheap premium that leads to a $4,000 surprise bill isn't actually a bargain.
Higher-Premium Options
Comprehensive plans like standard Plan G appeal to people who want predictable costs and near-complete coverage after Medicare pays. You'll still owe the Part B deductible, but almost everything else is covered.
A higher premium doesn't automatically mean better value. Compare the dollar difference in premium against the coverage gap it fills. If the premium difference is $600 a year but you'd rarely hit that much in out-of-pocket costs under a cheaper plan, the math might favor the lower-cost option.
Long-Term Value
Build a simple comparison covering:
- Annual premium cost
- Expected copayments and deductible exposure
- Likely rate increases over time
- Prescription drug costs
- Financial impact if you face a major illness
One more note: Medigap works with Original Medicare, not Medicare Advantage. These are structurally different products with different cost patterns, so compare them carefully before switching from one to the other.
How to Estimate the Right Medigap Budget
Before requesting quotes, gather these details:
- Age and ZIP code
- State and tobacco status
- Part A and Part B enrollment status
- Preferred doctors and current prescriptions
- Expected healthcare needs
Build a simple worksheet separating fixed costs from variable ones:
Fixed monthly costs:
- Medigap premium
- Part B premium
- Part D premium (if separate)
Variable/potential costs:
- Expected copayments
- Deductibles
- Uncovered services
- Emergency reserve fund
Compare quotes from several insurers for the same plan letter — this is where real savings often hide. Ask each company about their rating method, household discounts, payment options, rate-increase history, and renewal rules.
Timing matters. The six-month Medigap Open Enrollment Period begins when you turn 65 and enroll in Part B, and it offers strong protections against medical underwriting. Missing this window can mean facing underwriting later, so confirm your eligibility timeline early.

What Many People Miss When It Comes to Medigap Costs
A few mistakes come up again and again when beneficiaries shop for Medigap:
- Chasing the lowest premium without checking the fine print. Deductibles, copays, Part D costs, and future rate increases all shape your real annual cost.
- Assuming same-letter plans cost the same everywhere. Plan G benefits are identical by law, but premiums, rating methods, and financial stability still differ by insurer.
- Waiting too long to enroll. Miss your protected window without guaranteed-issue or state protections, and you may face medical underwriting later.
Confirm eligibility on Medicare.gov, with your state insurance department, or with a licensed advisor before that window closes.
Conclusion
Medigap cost isn't a fixed number. It depends on your plan choice, insurer, location, age, tobacco use, the insurer's rating method, and when you enroll. There's no single national price that applies to everyone.
The right budget balances your monthly premium against likely out-of-pocket expenses, prescription drug costs, uncovered care, and how much financial uncertainty you're willing to carry. Someone who rarely visits the doctor might prioritize a lower premium; someone managing chronic conditions might value predictability more.
Before you enroll or switch:
- Verify current rates on Medicare.gov, through your state insurance department, or with a carrier
- Compare multiple quotes for the same plan letter
- Get individualized guidance if you're unsure which trade-off fits

Frequently Asked Questions
How much should I expect to pay for a Medicare Supplement?
Premiums vary substantially based on your plan choice, insurer, state, age, tobacco use, and the insurer's rating method. Rather than relying on a national average, request quotes specific to your ZIP code and age.
How much will Medicare supplement plans cost per month in 2026?
2026 examples range from roughly $50/month for high-deductible plans to $270+/month for comprehensive Plan G, depending on insurer and state. These figures are illustrative, not guaranteed, and exclude separate Part B or Part D premiums.
Is a Medicare Supplement worth the cost?
It depends on your health needs and risk tolerance. Medigap offers predictable costs and reduced cost-sharing, but you may pay more in premiums than you'd spend out-of-pocket during a low-usage year.
What is the most cost-effective Medicare Supplement plan?
It depends on how often you use care and your budget priorities. Plan G fits people who want comprehensive coverage. Plan N or high-deductible options usually cost less if you can handle more out-of-pocket exposure.
What is the most popular supplement plan for Medicare?
Plan G is currently the most popular, accounting for about 39% of standardized-plan enrollment according to a 2025 industry report using 2023 data. Popularity doesn't guarantee it's the right fit for your individual health needs and budget.
What is the best secondary insurance if you have Medicare?
The right choice depends on your eligibility, budget, providers, and prescriptions. Medigap pairs with Original Medicare for broad doctor access. Medicare Advantage, employer coverage, Medicaid, or standalone Part D each fit different situations.
