Most people pay no monthly premium for Medicare Part A because they have enough Medicare-covered work history. For people who need to buy Part A, the 2026 monthly premium is $311 for the reduced-premium category or $565 for the full-premium category.
Social Security determines your official Medicare-covered work quarters and whether you qualify for premium-free Part A.
The calculator uses your selected work-quarter category and the 2026 Part A premium amounts to estimate your monthly cost. If you select the late enrollment option, it also estimates the possible Part A penalty.
Choose 40 or more quarters, 30–39 quarters, fewer than 30 quarters, or Not sure.
If you need to pay for Part A and delayed enrollment, select Yes and enter the number of years delayed.
Review the estimated premium, the category used, and any applicable late enrollment estimate.
The formula and the actual numbers used are displayed inside the calculator so the result is not a black box.
The Part A late enrollment penalty applies to people who have to buy Part A and do not enroll when first eligible. The monthly premium may increase by 10%.
The higher premium is generally paid for twice the number of years enrollment was delayed. The calculator applies that rule only when you select a premium-paying Part A category and choose to estimate the penalty.
Medicare states that people who qualify for certain Special Enrollment Period conditions generally do not have to pay the Part A late enrollment penalty.
Eligibility for a Special Enrollment Period depends on your circumstances. Confirm your enrollment rights with Medicare or Social Security before relying on an estimate.
