Understanding what you will actually pay for Medigap coverage is one of the most important steps in Medicare planning. The honest answer to how much Medicare Supplement plans cost is that it varies widely, from relatively modest monthly premiums to several hundred dollars a month, depending on the plan letter you choose, your age, where you live, your tobacco status, and which insurer you buy from. Because premiums are set individually by each carrier and change over time, no article can quote a single accurate price for your situation. What we can do is explain exactly what drives the cost, how to compare fairly, and which pieces of the Medicare bill are set by the federal government for 2026, so you can budget realistically and shop with confidence.
Why There Is No Single “Typical” Price
Medigap benefits are standardized by plan letter, meaning a Plan G from one insurer covers the same Medicare gaps as a Plan G from any other insurer. What is not standardized is the price. Two carriers can sell the identical Plan G in the same ZIP code and charge substantially different premiums, and the gap between the least and most expensive carrier for the same plan can be large. This is the single most important thing to understand about Medicare Supplement plans cost: because coverage is the same, price shopping across carriers is one of the few ways to save money without giving up any benefits. For a side-by-side look at what each plan letter actually covers, see our Compare Medicare Supplement Plans guide.
Rather than quoting prices that would be out of date the moment they are published, treat any premium you see online as an estimate only, and get real quotes for your ZIP code, age, and tobacco status before deciding.
The Main Factors That Drive Your Premium
Plan Letter
The plan letter is the biggest single driver of cost, because more comprehensive plans that leave you with fewer out-of-pocket gaps generally carry higher premiums. Plan G and Plan N are the most popular choices for people newly eligible for Medicare. Plan F and Plan C offer the most complete coverage but are closed to anyone who became eligible for Medicare on or after January 1, 2020; only people eligible before that date can still buy them. Lower-premium options such as Plans K and L cap their benefits and leave you with more cost-sharing in exchange for a smaller monthly bill.
Rating (Pricing) Method
How an insurer sets and raises your premium over time depends on its rating method, and there are three:
- Community-rated: everyone with the plan pays the same base premium regardless of age. Starting premiums are often the highest of the three, but they tend to grow the slowest with age.
- Issue-age-rated: your premium is based on your age when you buy the policy and does not rise simply because you get older, though it can still rise with inflation.
- Attained-age-rated: your premium is based on your current age and increases as you get older, on top of inflation. These plans often look cheapest at 65 but can become the most expensive over a long retirement.
Understanding the rating method is essential for projecting Medicare Supplement plans cost over your lifetime, not just in your first year. For a long retirement, a community-rated or issue-age-rated policy can end up cheaper in total even when it costs more at the start, so it is worth comparing the same plan under different rating methods.
Age, Gender, and Tobacco Use
Under attained-age and issue-age pricing, the age at which you enroll affects your premium. Many states also allow insurers to charge different rates based on gender and on tobacco use, so a smoker typically pays more than a non-smoker for the same plan. Some carriers offer discounts (discussed below) that can offset part of these differences.
Location
Where you live has a significant effect on premiums. States and regions with higher healthcare costs, older populations, or fewer competing insurers tend to have higher Medigap premiums, and prices can differ meaningfully between urban and rural areas within the same state. A handful of states use different rules entirely; for example, some require community rating for all Medigap policies. For state-specific guidance, see our pages on Medicare Supplement Plans in PA, Plans in Maryland, and Plans in California.
Carrier
Finally, the insurer itself matters. Because benefits are standardized, differences in premium between carriers come down to their pricing strategy, expenses, and rate-increase history rather than better coverage. Checking a carrier’s history of rate increases through your state insurance department can help you avoid companies with a pattern of aggressive hikes.
What the Federal Government Sets for 2026
While Medigap premiums are set by private insurers, several pieces of your total Medicare cost are set federally and are the same nationwide. For 2026, according to Medicare.gov and CMS:
- Part B standard premium: $202.90 per month (higher for beneficiaries subject to income-related adjustments).
- Part B annual deductible: $283.
- Part A hospital deductible: $1,736 for each inpatient benefit period.
- Part D out-of-pocket cap: once your out-of-pocket spending on covered Part D drugs reaches $2,100 in 2026, you pay nothing more for covered drugs for the rest of the year.
These figures matter for Medigap shoppers because your plan letter determines which of them you still have to pay. Notably, Plan G covers most gaps but not the Part B deductible, so a Plan G enrollee pays that $283 out of pocket in 2026 before the plan’s coverage of the remaining Part B costs kicks in. Plan F, which is closed to newly eligible beneficiaries, does cover the Part B deductible, which is one reason its premiums often run higher.
Total Cost of Coverage Beyond the Medigap Premium
Monthly Medigap premiums are only part of your total Medicare Supplement plans cost. Your complete annual outlay generally includes the Part B premium ($202.90 per month in 2026 for most people), your Medigap premium, a standalone Part D prescription drug premium (which varies by plan), any Part B deductible your plan does not cover, and your out-of-pocket drug costs up to the 2026 Part D cap of $2,100. Because so many of these numbers depend on your specific plan and location, the most reliable way to estimate your total is to add your quoted Medigap and Part D premiums to the fixed federal figures above.
It is also worth comparing this predictable structure to Medicare Advantage. A $0-premium Advantage plan still requires you to pay the Part B premium, and it exposes you to cost-sharing up to a federally set annual maximum out-of-pocket limit during a high-use year, whereas a comprehensive Medigap plan trades a higher, steadier premium for far more predictable out-of-pocket costs. Our Medicare Advantage vs Supplement guide walks through the tradeoffs in detail.
The High-Deductible Plan G Option
If a lower monthly premium is your priority, High-Deductible Plan G is worth understanding. It provides the same benefits as standard Plan G, but you pay a high annual deductible (an amount set by federal rules and adjusted each year) before the plan begins to pay. In exchange, the monthly premium is typically much lower than standard Plan G. This can appeal to healthier beneficiaries who do not expect heavy medical use and want to minimize their fixed monthly cost, while accepting more risk in a bad year. Check the current year’s high-deductible amount before choosing, since it changes annually.
How to Reduce Your Medigap Costs
Enroll During Your Medigap Open Enrollment Period
Your Medigap Open Enrollment Period is a one-time, six-month window that begins the month you are both 65 or older and enrolled in Medicare Part B. During this window you generally have guaranteed-issue rights, meaning insurers cannot deny you coverage or charge you more based on your health. Waiting beyond this window can expose you to medical underwriting, which may raise your premium or result in a denial, so timing your enrollment well is one of the most valuable cost-control moves you can make.
Take Advantage of Discounts
Many insurers offer discounts that can lower your premium, such as non-smoker discounts, household discounts when two people in the same home hold policies, discounts for paying annually instead of monthly, and discounts for automatic electronic payment. The exact discounts and amounts vary by carrier and state, so ask each insurer what it offers and whether discounts can be combined.
Consider Plan N Instead of Plan G
Plan N usually carries a lower premium than Plan G. The tradeoff is that Plan N involves modest copays for some office and emergency-room visits and does not cover Part B excess charges. For many beneficiaries, especially those in states that prohibit excess charges, Plan N can deliver strong overall value. See our Medicare Plan N vs Plan G comparison to weigh the difference.
Shop Multiple Carriers
Because benefits are standardized, comparing premiums from several insurers for the same plan letter is one of the most effective ways to save. The least and most expensive carriers for the identical plan in the same ZIP code can differ substantially. Use the official Medicare.gov Medigap plan finder or our best supplemental insurance companies guide as a starting point, then request direct quotes.
Match the Rating Method to Your Time Horizon
If you are enrolling at 65 and expect a long retirement, an issue-age-rated or community-rated plan may cost less over time even when its starting premium is higher than an attained-age plan. Ask each carrier which method it uses, and think about cumulative cost over 15 to 20 years, not just year one.
Rate Increase Trends
Medigap premiums generally rise over time due to medical inflation and, for attained-age plans, aging. The size of increases varies by insurer, plan, and market; some carriers in competitive markets hold rates relatively steady, while others raise them more sharply. Plans with aging, shrinking risk pools, particularly the closed Plan F, tend to face faster premium growth over time because fewer new, healthier enrollees are joining to balance claims. Plan G and Plan N, which continue to attract new enrollees, generally have more stable pools. Reviewing an insurer’s rate-increase history through your state insurance department is a practical way to avoid carriers with a pattern of large hikes.
Frequently Asked Questions
Why does my neighbor pay less for the same Medigap plan?
Even for the identical plan letter, premiums differ from person to person based on the age at enrollment (under age-based rating), gender where allowed, tobacco use, ZIP code, the specific insurer, and any discounts each person qualifies for. Two neighbors with the same plan letter can pay different amounts because they bought from different carriers or enrolled at different ages.
Do Medigap costs go down after a certain age?
No. Medigap premiums do not decrease with age. Under attained-age rating they rise as you get older; under issue-age and community rating they do not rise because of age but can still increase with inflation. There is no age at which premiums begin to fall.
Can I deduct Medigap premiums on my taxes?
Medigap premiums generally count as qualified medical expenses for federal income tax purposes. If you itemize, you can deduct the portion of your total unreimbursed medical expenses that exceeds 7.5 percent of your adjusted gross income. Some self-employed individuals may be able to deduct premiums differently. Tax rules are individual, so consult a qualified tax professional or the IRS for your situation.
How do I find the exact cost for my situation?
The most accurate way is to request quotes directly from insurers or use the official Medicare.gov Medigap plan finder, entering your ZIP code, age, gender, and tobacco status to see real rates. Any figure you see in an article is only a rough estimate and should not be used for budgeting without a current quote.
Planning Your Medigap Budget
When budgeting for Medigap, plan for premiums to rise over time rather than staying flat, and build in your Part B premium, Part D costs, the Part B deductible your plan does not cover, and expenses Medicare does not touch such as most dental, vision, and hearing care. The total cost of Medicare coverage with a Medigap policy is meaningful, but it buys some of the most predictable and comprehensive protection available to Medicare beneficiaries. Rather than anchoring to any single advertised price, focus on the drivers of cost, get several real quotes, and choose the plan letter and rating method that fit your health and your time horizon.

TL;DR
Medigap prices vary too much to quote a single number: cost depends on the plan letter, the insurer’s rating method (community, issue-age, or attained-age), your age, location, tobacco status, gender where allowed, and the carrier. Because each lettered plan’s benefits are standardized, shopping several insurers for the same plan is a rare way to save with no loss of coverage. For 2026 the federally set figures are a $202.90 Part B monthly premium, a $283 Part B deductible (which Plan G leaves you to pay), a $1,736 Part A deductible, and a $2,100 Part D out-of-pocket cap. Enroll during your six-month Medigap Open Enrollment Period for the best access, and always get current quotes for your ZIP code rather than relying on any estimate.
