How Much Does Medicare Supplement Insurance Cost Per Month?
What You’re Actually Paying For With Medicare Supplement Insurance
Here’s the honest truth: Original Medicare doesn’t cover everything. You already knew that, or you wouldn’t be reading this. What surprises most people is just how much can fall through the cracks. Copays, coinsurance, deductibles — they add up fast. Medicare supplement insurance (also called Medigap) is designed to cover those gaps so you’re not hit with a huge bill after a hospital stay.
But how much does it actually cost? That’s what we’re going to walk through together. The short answer is: it depends on the plan you pick, where you live, and your age. Monthly premiums can range anywhere from about $50 to $300 or more per month. Let’s break that down into something that actually makes sense.
Real Monthly Costs by Plan Type
There are 10 standardized Medigap plans available in most states. Each one is labeled with a letter: Plan A, Plan B, Plan C, Plan D, Plan F, Plan G, Plan K, Plan L, Plan M, and Plan N. The most popular ones right now are Plan G and Plan N, especially for people new to Medicare.
Here’s a rough idea of what people typically pay per month in 2024:
- Plan A: Around $70 to $150 per month. It covers the basics but not much else.
- Plan G: Typically $100 to $200 per month. This is currently the most comprehensive plan available to new enrollees. It covers nearly everything except the Part B deductible, which is $240 in 2024.
- Plan N: Usually $80 to $160 per month. Lower premium than Plan G, but you’ll pay small copays at doctor visits (up to $20) and up to $50 for emergency room visits that don’t result in an admission.
- Plan F: Often $130 to $230 per month. It’s the most comprehensive plan ever offered, but it’s only available if you became eligible for Medicare before January 1, 2020.
- Plan K and Plan L: Generally cheaper, often $50 to $100 per month, but they only cover a percentage of costs rather than the full amount.
These numbers are averages. Your actual quote could be higher or lower depending on your zip code, the insurance company you go with, and how the company prices its plans.
One thing a lot of people don’t realize: all insurance companies selling Plan G must offer the exact same benefits. The only difference is price and customer service. That means it really does pay to shop around.
Why Your Price Might Be Different From Your Neighbor’s
Insurance companies use three different methods to set their prices, and this affects how much you’ll pay now and in the future.
- Community-rated: Everyone pays the same premium regardless of age. A 65-year-old and a 75-year-old pay the same rate. These plans can be a good deal if you’re older.
- Issue-age-rated: Your premium is based on how old you are when you first buy the policy. It won’t go up just because you get older, but it will still increase over time due to inflation.
- Attained-age-rated: Your premium starts low but goes up every year as you age. These are the most common, and they often look like a great deal at 65 but can become expensive by your 70s.
Location matters too. If you live in a high cost-of-living state like New York or California, you’ll generally pay more than someone in a rural Midwestern state. A 67-year-old woman in Florida might pay $145 per month for Plan G, while the same plan in Texas might cost her $118.
Tobacco use can also raise your rates. Some companies charge smokers 10% to 15% more. And in most states, if you don’t sign up during your open enrollment window (the 6 months after you turn 65 and enroll in Medicare Part B), companies can actually charge you more or deny coverage based on health conditions. That’s a big deal and worth paying attention to.
Is Medicare Supplement Insurance Actually Worth the Cost?
This is the question everyone really wants answered. And honestly, it depends on how much healthcare you use.
Think about it this way. If you’re hospitalized for a week, your Medicare Part A deductible alone is $1,632 in 2024. That’s just for days 1 through 60. If you need extended care, the daily costs pile on. A good Medigap plan would cover that entire deductible. One hospital stay could more than pay for a full year of premiums.
On the flip side, if you’re healthy and rarely see a doctor, you might pay $1,500 to $2,000 a year in premiums and use very little of it. Some people are okay with that trade-off for the peace of mind. Others would rather take the risk and keep the money.
The typical approach for someone who wants solid coverage without overpaying is to go with Plan G or Plan N. Plan G gives you comprehensive coverage for a predictable monthly cost. Plan N saves you money each month but adds some out-of-pocket costs when you actually use it. Neither is wrong. It just depends on your health history and how you feel about uncertainty.

Frequently Asked Questions
Does Medicare supplement insurance cost the same everywhere?
No, prices vary quite a bit by state and even by zip code. Insurance companies set their own premiums, so you could see a $50 to $80 difference per month for the exact same plan depending on where you live and which company you choose. Always compare at least 3 to 5 quotes before deciding.
Can my Medicare supplement premium go up over time?
Yes, it can. Most plans use attained-age pricing, which means your premium increases as you get older. Even community-rated and issue-age-rated plans can increase due to general medical inflation. When you’re shopping, ask each company how often they’ve raised rates in the past and by how much. That history tells you a lot.
What’s the difference between Medicare Advantage and Medicare supplement insurance?
They’re two completely different approaches. Medicare Advantage (Part C) replaces your Original Medicare and usually works like an HMO or PPO with a network of doctors. Medicare supplement insurance works alongside Original Medicare to fill in cost gaps. You can’t have both at the same time. Supplement plans tend to give you more flexibility to see any doctor who accepts Medicare, while Advantage plans often have lower premiums but more restrictions on where you can get care.
