What Plan G Costs Look Like in 2024
Medicare Supplement Plan G represents one of the more frequently chosen supplemental coverage options, and understanding its cost structure matters because premiums can vary significantly based on where you live and which insurance company you select. Monthly costs for Plan G in 2024 typically range from $130 to $280 per month, though you may encounter prices both lower and higher depending on your specific circumstances and location.

The price you see is just one piece of the cost puzzle. Plan G has what Medicare calls a "deductible"—a set dollar amount you pay out-of-pocket before your plan starts covering costs. For 2024, this deductible sits at $240. This means that before Plan G begins paying its portion of covered services, you'll need to pay this amount yourself each year. After you meet that deductible, Plan G covers a significant portion of expenses that Original Medicare doesn't pay for, including copayments, coinsurance, and other out-of-pocket costs.
Insurance companies use different pricing methods. Some companies price based on your age when you enroll—locking in a rate that may increase more slowly over time. Others use "community rating," meaning everyone in your geographic area pays the same premium regardless of age. A third approach, "issue-age rating," charges based on your age at the time you purchase the plan. These different approaches mean that two people in the same state might pay very different premiums for identical coverage.
One practical reality: Plan G premiums tend to increase annually. The increases reflect rising healthcare costs and sometimes reflect the insurance company's actual claims experience. Increases typically range from 3% to 8% per year, though some years see higher jumps depending on the insurer and region.
Takeaway: Before comparing Plan G to other options, research pricing from at least three different insurance companies in your state. Premium prices vary widely, and spending time comparing can save you hundreds of dollars annually.
How Plan G's Deductible Affects Your Real Costs
The $240 annual deductible for Plan G works differently than many people initially assume. This deductible applies only to the services that Plan G covers—it doesn't affect your Original Medicare Part B deductible or your prescription drug costs. Understanding this distinction matters because it changes how much money actually comes out of your pocket.

Here's a concrete example: Suppose you visit your doctor in January and receive a bill for $200 in copayments that Plan G normally covers. Since you haven't met your $240 deductible yet, you pay the full $200 out-of-pocket. The deductible is now reduced to $40. Later that month, you have additional medical costs totaling $75 in copayments. You pay $40 (to complete your deductible) and Plan G pays $35. From February onward through December, Plan G covers these copayments at 100%—no additional deductible applies until the next calendar year.
The deductible resets every January 1st. This timing matters for people who have clustered medical expenses. Someone with significant healthcare needs in November and December might meet their deductible easily, then start fresh in January with the clock reset. Conversely, someone with minimal medical needs might pay the monthly premium all year and never reach the deductible threshold, meaning they receive less value from the supplemental coverage.
When calculating true Plan G costs, you need to factor in both the monthly premium and the likelihood that you'll meet the deductible. If your annual healthcare expenses are high, you'll reach $240 relatively quickly, and then Plan G covers additional qualifying costs. If your healthcare expenses are minimal, you'll pay premiums throughout the year without maximizing the plan's benefits. The math changes based on your individual health situation.
Takeaway: Calculate your potential Plan G costs by adding (monthly premium × 12) plus $240 deductible. This gives you a reasonable estimate of maximum out-of-pocket costs in a year when you have medical expenses. Compare this total to other Plan options before enrolling.
Regional Variations and What They Tell You
Plan G premiums vary dramatically by state and even by county. A person in Kansas might pay $145 per month for Plan G, while someone in Massachusetts might pay $290 for the identical coverage. These variations stem from multiple factors: state insurance regulations, healthcare costs in that region, competition among insurance providers, and historical claims data for that geographic area.

Some states regulate supplemental insurance premiums tightly, which can limit how much insurers can charge or how often they can increase rates. Other states have more relaxed regulations. New York, Florida, and Massachusetts—states with significant retiree populations—often have higher Plan G premiums than rural states with smaller senior populations. Higher premiums don't necessarily mean better coverage; they reflect local healthcare economics.
Within states, county-level variation also occurs. Urban areas typically have higher premiums than rural areas because healthcare providers in cities charge more for services. A retired person in New York City might pay 40-50% more for Plan G than someone living in rural upstate New York, despite having access to identical coverage.
Insurance company availability differs by region too. Some states have 15+ companies offering Plan G, creating price competition that keeps premiums lower. Other states have only 3-5 companies offering Plan G, reducing competitive pressure on pricing. If you live in an area with limited options, you may have less negotiating power in terms of finding lower premiums. This is why people sometimes relocate in retirement and notice their supplemental insurance costs change substantially.
Demographic patterns within regions also influence pricing. Areas with healthier senior populations might see lower premiums than areas with older, sicker populations, because insurance companies price based on anticipated claims.
Takeaway: Don't assume Plan G costs the same everywhere. Request quotes from multiple companies operating in your specific county or zip code. Geographic variation is real and significant—sometimes a difference of $1,500 to $2,000 annually depending on where you live.
When Plan G Costs Less Than Other Plans (And When It Doesn't)
Plan G isn't automatically the cheapest or most expensive supplemental option. The cost comparison depends on several factors specific to your situation. Plan F, which was once the most popular supplement, now may cost more monthly than Plan G despite covering the Part B deductible that Plan G doesn't cover. Since Plan F is no longer sold to new enrollees who became Medicare-eligible after January 1, 2020, most people shopping for supplements today are choosing between Plan G and Plans like N, D, or high-deductible G.

High-deductible Plan G offers significantly lower monthly premiums—sometimes $50-100 less per month—compared to standard Plan G. The tradeoff: you must pay up to $2,700 out-of-pocket (the 2024 deductible) before the plan covers anything. This structure works well for people who don't anticipate major medical expenses and want to minimize monthly costs. For someone with chronic conditions requiring ongoing specialist visits and hospitalizations, high-deductible Plan G might result in higher total costs than standard Plan G.
Plan N typically costs $20-40 less per month than Plan G but requires you to pay copayments for certain doctor visits and emergency room visits. If you visit doctors frequently, Plan N's copayments add up, potentially making Plan N costlier overall than Plan G. If you see doctors infrequently, Plan N might deliver genuine savings.
The decision between plans requires running numbers specific to your healthcare patterns. Someone who had five specialist visits last year and expects to have similar usage should calculate: (Plan G monthly premium × 12) versus (Plan N monthly premium × 12) + (expected copayments). Real costs emerge only when you account for your actual usage patterns, not theoretical benefits.
Regional factors compound these comparisons. In some states, the premium difference between Plan G and Plan N might be $15 monthly. In other states, it might be $50 monthly. The larger the premium gap, the more copayments you'd need to pay on Plan N before Plan G becomes the better deal.
Takeaway: Compare at least three plan options (Plan G, Plan N, and high-deductible Plan G) by calculating total expected costs based on your anticipated healthcare usage. The cheapest monthly premium isn't always the cheapest annual cost.
