💰 What If You Invested the Premium Savings vs MA?
If a Medigap plan costs more upfront but you invest the difference in years when Medigap is cheaper, here's the potential growth.
Calculated using your MA net cost (after benefits credit) vs each Medigap plan. In years where Medigap costs MORE than MA, no contribution is made — the comparison is honest in both directions.

Note: In years where MA costs more than a Medigap plan (common in moderate/high utilization years), no investment contribution is made for that year. The model accurately reflects both directions. A negative 20-year invested value means Medigap was cheaper overall — the "savings" favored Medigap, not MA. This is a simplified illustration assuming consistent monthly contributions of the growing savings amount. It does not account for taxes, inflation, or investment fees. Past investment returns do not guarantee future results. The investment projections shown are for illustrative purposes only and do not constitute investment advice. Returns are not guaranteed.
