Part B Late Enrollment Penalty Calculator for Tucson, AZ
Medicare adds a late enrollment penalty if you skip signing up for Part B when you're first eligible and you don't have coverage through a job you or your spouse actively works at. The extra amount gets tacked onto your monthly premium, and for most people it sticks around permanently.
Punch your numbers into the calculator below for a quick estimate, then read the notes underneath to figure out whether the penalty even applies to your situation.
- 10% added for each full 12 months delayed
- The surcharge usually lasts as long as you have Part B
- Employer coverage from active work protects you

Only count the months you had no active-employer coverage, whether that was through the University of Arizona, Raytheon on the south side, or anywhere else.
Use whatever standard Part B premium Medicare has published for the current year.

This is an estimate, not a bill. Medicare adds 10% of the standard premium for every full 12-month stretch you went without Part B when you could have had it, and that surcharge usually rides along for as long as you're enrolled in Part B.
Context
When this penalty does and doesn't apply
You're in the clear while you have group health coverage tied to current employment, yours or your spouse's. Retiree coverage, COBRA and marketplace plans don't count toward this. Once that active job ends, you get an eight-month Special Enrollment Period to sign up for Part B with no penalty.
Prescription drug coverage carries its own separate penalty. If you're weighing whether to hold off on Part B, read about Part D drug plans too, and see the full list of mistakes to avoid.
