Average Cost of Medicare Supplements in 2026
Key Factors Affecting Medigap Costs in 2026
The cost of Medicare Supplement (Medigap) plans in 2026 hinges on multiple variables, which all prospective policyholders should understand before committing to a plan. Premiums can range significantly, with averages between $100 and $300 a month, but the actual amount each person pays will depend on several personal and plan-specific factors:
- Policy Type: The more comprehensive the coverage, the higher your monthly premiums. For example, Plan F historically carried some of the highest premiums due to its full coverage, though it’s now unavailable to new enrollees. Plan G offers similar coverage at slightly lower costs, while Plan K provides partial benefits for the lowest premiums, making it an option for those seeking basic coverage and lower fixed costs.
- Location: Premiums are heavily determined by where you live. Areas with higher medical costs, such as Florida, see steeper rates than states like Texas or California. For localized insights, check out the Colorado Medicare Supplement Plans: 2026 Rates & Comparison for detailed regional pricing examples.
- Age and Gender: Rates increase with age-those at 75 typically pay 30% more than those at 65, reflecting the rising risk factors associated with age. Additionally, some insurers offer slightly reduced premiums for females.
- Enrollment Timing: The most cost-effective time to enroll is during your initial open enrollment period (six months from when your Part B coverage begins). You won’t be subject to medical underwriting or denial for pre-existing conditions, and you’ll lock in the best rates.

- Household Discounts: Insurers may offer up to 15% discount if two eligible adults reside in the same household-for example, Mutual of Omaha provides a 12% spousal discount.
- Pricing Method: Companies use various pricing methods-attained-age (rises with age), community-rated (same rate regardless of age), or issue-age-rated (premium locked in at purchase age). The chosen method impacts how your premium changes over time.
Understanding these factors helps in anticipating annual premium increases and making an informed decision when evaluating Medicare Supplement cost in 2026.
Estimated Premiums by Plan Type and Location
Private insurers set different premiums for standardized Medigap plans, resulting in a broad cost spectrum. The most popular options include Plan F (for those eligible), Plan G, Plan N, and high-deductible variants. The table below illustrates typical 2026 rates across several states and ages:
| Plan Type | Average Monthly Premium | Examples by Location/Age (2026) |
|---|---|---|
| Plan F (most comprehensive, closed to new enrollees post-2019) | ~$230 | Male 65 FL: $248; CA: $212; TX: $221 Female 65 FL: $241; CA: $212; TX: $218 Male 75 FL: $317; CA: $265; TX: $256 |
| Plan G (most popular after F) | Varies, lower than F | Male 65 FL: $191; CA: $141; TX: $151 Female 65 FL: $183; CA: $141; TX: $134 Male 75 FL: $263; CA: $208; TX: $196 |
| Plan K (cheapest, basic coverage) | ~$77 | Out-of-pocket max: $8,000/year |
| Plan L | Higher than K | Out-of-pocket max: $4,000/year |
| Overall Range | $61-$354 | $100-$300 typical, by demographics |
These averages are based on current insurer filings and may change as inflation and medical costs rise. For the most accurate quote, consider collecting offers from several providers and factoring in local trends-rates in urban centers or high-cost states tend to be higher.

High-Deductible Medigap Options
High-deductible options for Plans F and G require you to pay a $2,950 deductible (2026 estimate) before coverage begins, but premiums are substantially lower-typically $40-$80/month depending on location and age. These are a cost-effective alternative for healthy seniors or those comfortable with higher upfront expenses in exchange for lower premiums.
Plan N Premiums and Features
Plan N offers mid-range premiums, slightly lower than Plan G, but you’ll incur modest copays for doctor and emergency room visits. It’s an excellent value for people who don’t expect frequent specialist care. Expect monthly premiums between $120 and $220, depending on state and age.
Premium Variation Examples
- 65-year-old male in Florida: Plan G = $191/month; Plan N = ~$145/month
- 75-year-old female in Texas: Plan G = $196/month; Plan F = $256/month
- 65-year-old female in California: Plan N = ~$126/month; High-Deductible G = ~$60/month
Comparing plans is crucial, as identical Medigap plans can have very different premiums across insurers in the same area.
Total Out-of-Pocket Costs (Including Part B and D)
Medigap plans are designed to minimize out-of-pocket costs by filling most of the gaps left by Original Medicare:
- Part B Premium: $202.90/month in 2026 (standard; some pay more based on income). For enrollment details, refer to How to Get Medicare Part B Coverage in 2026.
- Medigap Premium: Add your chosen plan’s monthly premium for your demographics.
- Part B Deductible: $283/year (2026 rates). Plans like G require you to pay this; some legacy plans (like some F contracts) may cover it.
- Part D Drug Plan: Medigap does not cover prescription drugs. Average Part D premiums range from $30 to $100/month, plus prescription copays. Shop plans annually for best value; see Medicare Part D Plans California 2026 Overview for more info.
- Other Out-of-Pocket Costs: Under Plan G/N, after the Part B deductible is satisfied, most hospital and medical expenses are fully covered. With Plan K or L, you’ll pay a percentage of costs until reaching the annual cap ($8,000 for K, $4,000 for L).
- High-Deductible Plans: Must pay $2,950 out-of-pocket before coverage starts (applies to eligible G/F).
| Plan | Expected Out-of-Pocket Costs |
|---|---|
| Plan G (most popular) | Part B premium + deductible ($283) + Plan G premium; $0 for most remaining services after deductible |
| Plan N | Similar to Plan G, but $20 copay per office visit and $50 ER copay (if not admitted) |
| Plan K/L | Pays a portion up to OOP max ($8,000/$4,000 respectively), then 100% coverage for rest of the year |
| High-deductible G/F | $2,950 deductible; lower monthly premium |
Original Medicare has no annual cap on out-of-pocket expenses, whereas Medigap plans protect against catastrophic costs. To understand how these costs stack up over the year and what counts toward your true out-of-pocket, read What Does TrOOP Mean in Medicare? True Out-of-Pocket Costs.
Medigap vs. Medicare Advantage: Cost Comparison
One of the most common questions is: Which is more cost-effective-Medigap or Medicare Advantage? Both options cover the basics, but their cost structures and out-of-pocket risks are very different. Here is a comparative breakdown for 2026:
| Aspect | Medigap + Original Medicare | Medicare Advantage |
|---|---|---|
| Monthly Premium | $100-$300+ (plus $202.90 Part B) | Avg. $14 (often $0) + Part B |
| Out-of-Pocket Exposure | Minimal-mainly the Part B deductible ($283); after that, 100% coverage for many services (Plan G, N) | Variable copays ($0-$65 per visit, hospital $200-$450/day); annual out-of-pocket max $5,900-$9,250 in-network |
| Deductibles | Part B deductible; some plans cover this | Plan-specific (often includes Part B deductible) |
| Total Potential Cost (OOP + premiums) | Predictable, rarely exceeds combined annual premiums/deductible | Potentially low for healthy users, but high for frequent care (chronic conditions) |
| Provider Access | Any provider nationwide that takes Medicare | Network restrictions; referrals may be required |
| Extras (Dental, Vision, Fitness) | Not included; separate plans needed | Often included-dental, vision, hearing, fitness and possibly Part D drugs |
Medigap’s higher upfront premiums pay for the peace of mind of predictable costs and broad provider access, making it ideal for people with chronic conditions or who expect many doctor visits. In contrast, Medicare Advantage is attractive for healthy, low-utilization seniors seeking minimal premiums and integrated benefits, but the risk of high unexpected bills is greater for those who develop serious health needs.

How to Get the Best Medigap Rate in 2026
The key to maximizing Medicare Supplement value in 2026 is a combination of timing, active comparison shopping, and a deep understanding of your health needs and budget. Here’s how to ensure you pay the lowest possible premium for the coverage you need:
- Enroll During Your Medigap Open Enrollment Period: This 6-month window begins the month your Medicare Part B becomes effective and you are age 65 or older. During this period, insurers cannot deny coverage or charge higher premiums due to pre-existing conditions.
- Compare Quotes: Premiums for identical Medigap plans often vary significantly between insurers-it pays to shop around for the best combination of price and service quality. Tools and databases at Medicare.gov and trusted independent brokers streamline this process. For state-specific insights, see Colorado Medicare Supplement Plans: 2026 Rates & Comparison.
- Ask About Household and Spousal Discounts: Many companies offer discounts of up to 15% when multiple eligible adults in one household have Medigap coverage.
- Consider High-Deductible or Lesser-Known Plans: If healthy and able to handle more upfront costs, high-deductible plans (F/G) or plans with cost-sharing (K/L) can yield substantial savings on monthly premiums.
- Review Annual Changes: Rates and rules change each year as medical costs and inflation rise. Even if you are already enrolled, check rates on your anniversary or open enrollment to ensure your plan remains the best value.
- Evaluate Tobacco or Healthy Lifestyle Discounts: Some insurers reward non-smokers or those with healthy habits-always ask about these credits.
Given the pace of cost changes, it’s highly recommended to obtain personalized quotes annually and review benefits each year. For more detailed guidance or to compare Medigap with other options, refer to What Medicare Supplemental Insurance Do I Need in 2026?.
