Medicare is the best health insurance for most retirees once they turn 65. The standard Part B premium is $202.90 a month in 2026, and most people pay no Part A premium. Enrollment opens three months before your 65th birthday month. Delaying Part B without other qualifying coverage adds 10% of the standard premium, $20.29 a month in 2026, for each full year you went without it, usually for as long as you have Part B.
Original Medicare has no yearly out-of-pocket limit, unlike Marketplace plans, which cap in-network costs at $10,600 for an individual in 2026. A Medicare Supplement (Medigap) plan helps pay your share of costs in Original Medicare.
Before 65, the ACA Marketplace is the main option for early retirees. Silver plans are the starting point if your household income is at or below 250% of the federal poverty level, because Silver is the only tier where cost-sharing reductions lower your deductible and copays.
