Prescription Cost Calculator
Estimate the total cost of a prescription based on unit price, quantity, refills, insurance coverage and copay.
Overview
Use this Prescription Cost Calculator to estimate what a medication may cost per fill and in total. Enter the retail price per unit, quantity dispensed, number of fills, insurance coverage percentage, copay and any discount to get a quick cost estimate.
How it works
The calculator first multiplies the unit price by the quantity to estimate the retail cost per fill. It then applies the insurance coverage percentage to estimate the insurer's share, compares the remaining amount with the fixed copay using a simplified approach, and subtracts any discount. The result is an estimated out-of-pocket cost per fill and across all fills.
