About This Calculator
Plan G is the most popular Medigap plan in 2024, covering all Medicare cost-sharing except the Part B deductible ($240 in 2024). Monthly premiums range from roughly $100–$300 depending on age, location, and insurer. Plan N costs 20–30% less than Plan G but has copays and excludes Part B excess charges — ideal for healthy retirees who rarely see specialists.
