How much is a medicare supplement plan G per month?

Medigap Plan G premiums typically range from about $32 to $628 per month, depending on your insurance company, your age, and where you live. That's a wide spread, and it comes down to how each carrier sets its prices. Here's the important part: every Plan G sold in your area covers the exact same benefits, no matter which company you buy from. The only real difference is the price. So a $120 plan and a $180 plan from two different carriers pay claims identically. That means shopping around matters. Plan G leaves you responsible only for the 2026 Part B deductible of $283, then covers the rest. CSG's county-level filings back that up nationally: the cheapest flagship-county Plan G rate at 65 we track is $109.75/mo, filed by Bankers Fidelity Assurance in Virginia as of September 10, 2026. The priciest flagship-county floor we track is $295.75/mo in Connecticut, filed by HealthSpring National Health (HCSC) — 2.7x the cheapest floor for the same federally standardized Plan G benefit.
