Medigap Plan G Calculator

Compare Medigap Plan G total cost against an alternative coverage approach.

About Medigap Plan G Calculator

Plan G converts variable medical costs into a fixed premium, so its cost barely changes between a healthy year and a serious illness. Alternatives are cheaper in low claim years and far more expensive in high ones. The comparison is really about risk tolerance rather than expected cost, which is why the worst case figures matter more than the expected ones.

Formula

Medigap Plan G
