How it works

We total Advantage premiums plus expected out-of-pocket, then compare to Medigap premiums plus a Part D plan plus its small out-of-pocket, and show which is cheaper for your assumptions.

Model a sick year too: Medigap's value shows up when out-of-pocket costs spike.

Two very different ways to cover Medicare

Medicare Advantage usually has a low or $0 premium but you pay as you go — copays for each visit, up to a yearly cap. Medigap (Medicare Supplement) flips that: a higher monthly premium buys near-zero costs when you actually need care, and you add a standalone Part D drug plan. Advantage often wins in healthy years; Medigap protects you in expensive ones.

The trade-off nobody mentions

Beyond cost, Advantage plans use networks and require referrals and prior authorizations; Medigap lets you see any doctor that takes Medicare, anywhere. And switching from Advantage back to Medigap later can require medical underwriting — so the first choice matters more than the price gap alone suggests.
