Compare the same service and billing unit
Use quotes for the same prescription, supply and included services. This tool compares calendar-month payments with a fixed prepaid term. If an offer bills every four weeks, normalize it with the billing-period tool first. A smaller monthly equivalent does not change the amount due upfront.
Read the early-exit table
The prepaid column keeps the full term amount at every row. It assumes no refund when you leave early and no additional fees. The monthly column assumes you can end future payments after each completed month. Both assumptions must match the actual contract. A cancellation notice period, medical-disqualification refund or financing agreement can change your result.
Keep clinical changes outside the estimate
The calculator does not predict how long you will need treatment, prescription changes or refund eligibility. It shows the financial commitment under the assumptions above. Entries stay in this tab and are not sent to Analytics.
