IEP Calculator

Medicare Initial Enrollment Period Calculator (Turning 65)

Your Medicare Initial Enrollment Period is a 7-month window around your 65th birthday. Missing it can result in permanent late-enrollment penalties. Enter your date of birth to find your exact dates.

Perfect for individuals approaching their 65th birthday who want to confirm their enrollment window.

How the IEP works: The 7-month window starts 3 months before your 65th birthday month, includes your birthday month, and ends 3 months after. Signing up in the first 3 months means your coverage starts the month you enroll. Signing up in the last 3 months may delay your coverage start date.

Your IEP is based on the month you turn 65.
