Age is one factor that Medicare Supplement Insurance (Medigap) companies can use when determining the premiums for plans. Your Medigap premium is how much you pay per month to be a member of the plan.

Medicare Supplement Insurance premiums tend to increase with age. As you compare Medigap quotes, it may be helpful to consider how your age could affect your Medigap premium costs over time.

In this guide, we break down the average monthly premiums of Medigap Plan G and Plan F by age, from age 65 to age 85.

How Much Does the Average Medicare Supplement Plan Cost in 2020?

The table below displays the average cost of Medicare Supplement Insurance Plan G and Plan F by age.1

Based on our analysis, we noted several key takeaways:

  • Medicare Supplement Insurance Plan F premiums in 2020 are lowest for beneficiaries at age 65 ($184.93 per month) and highest for beneficiaries at age 85 ($299.29 per month).

  • Medigap Plan G premiums in 2020 are lowest for beneficiaries at age 65 ($143.46 per month) and highest for beneficiaries at age 85 ($235.87 per month).

$204.52 70 $159.29
$210.55 71 $164.16
$216.66 72 $169.05
$223.02 73 $174.19

Is Medigap Plan G Better Than Plan F?

While there can be a sizable difference in average premiums between Plan F vs. Plan G, there's only a small difference in benefits these two plans offer.

  • Plan F provides coverage each of the 9 possible benefits that the 10 standardized Medigap plans can offer, including the Medicare Part B deductible. 

  • Plan G does not cover the Medicare Part B deductible, but it offers coverage for all of the same out-of-pocket Medicare costs that Medigap Plan F covers.

Medigap Plan F and Plan G are the two most popular Medigap plans.2

In 2021, the Part B deductible is $203 per year.

The $203 annual deductible equates to around $17.00 per month.

This means that a Plan G with a premium of no more than $17.00 per month more than a Plan F option could actually serve as a better value, provided you meet the entire Part B deductible.

Important: Plan F is not available to new Medicare beneficiaries who become eligible for Medicare on or after January 1, 2020. If you already have Medicare, you can still enroll in Plan F if the plan is available in your area.

How Does Age Affect Medicare Supplement Insurance Premiums?

There are three different age-related pricing models that Medicare Supplement Insurance companies use to determine their Medigap plan rates in 2020.

Each type of cost model can affect the average price of a given Medigap plan.

  • Community-rated Medigap plans
    With community-rated Medigap plans, every member of the plan pays the same rate, regardless of age.

    For example, an 82-year-old who enrolls in a community-rated Plan G will pay the same Medigap premiums as a 68-year-old beneficiary who has the same Plan G in the same market.

  • Issue-age-rated Medigap plans
    With issue-age-rated Medigap plans, premiums are based on your age at the time you enrolled in the plan.

    You will typically pay less for an issue-age-rated plan if you enroll in the plan when you're younger. Your premiums also won't increase based on your age.

  • Attained-age-rate Medigap plans
    Attained-age-rated Medigap plans set their premiums based on your current age. As you age, your Medigap plan premiums will gradually increase each year.

Medigap premiums can increase over time due to inflation and other factors, regardless of the pricing model your insurance company uses.
