Medicare Part B Penalty Calculator for Chicago
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 is actively working. That surcharge lands on your monthly premium and, for most people, never goes away.
Run the numbers below for a fast estimate, then check the notes to see if 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

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 the penalty does and doesn't apply
You're covered while you have group health insurance tied to current employment, yours or your spouse's. Retiree coverage, COBRA and marketplace plans don't count for this. Once that active employment ends, you get an eight-month Special Enrollment Period to sign up for Part B without a penalty.
Part D carries its own separate penalty. If you're on the fence about delaying either one, read up on Part D drug plans and check the full list of mistakes to avoid.
