Jacksonville Part B Penalty Calculator
Medicare adds a late enrollment penalty when you skip signing up for Part B at your first eligibility and you're not covered by a job you or your spouse currently works at. It gets folded into your monthly premium and, for most people, it stays there permanently.
Run the calculator below for a fast estimate, then check the notes underneath so you know whether this even applies to your situation.

Estimate only. Medicare calculates the penalty as 10% of the standard premium for each full 12-month period you could have had Part B but didn't, and it generally applies for as long as you have Part B.
Context
When this penalty applies, and when it doesn't
You stay protected as long as you're on group health coverage tied to current employment, yours or a spouse's. Retiree coverage, COBRA and marketplace plans don't count toward that protection. Once active employment ends, you get an eight-month Special Enrollment Period to sign up for Part B penalty-free.
This is common territory for the military retiree community around NAS Jacksonville and Naval Station Mayport, since TRICARE for Life works alongside Medicare rather than replacing it, and timing still matters. Part D carries its own separate penalty too. If you're weighing a delay, read about Part D drug plans and review the full list of mistakes to avoid.
