28 Day Prescription Refill Calculator

How to Use This Calculator

1. Enter your Total Medication Supply in days (e.g., 60 days for a 60-day supply)
2. Enter your Daily Dosage in units (e.g., 2 tablets per day)
3. Enter the number of Days Passed Since Last Refill
4. Click the Calculate button to see how many days are left before you need to refill your prescription

Example Calculation

If you have a 90-day supply of medication (90 days) and take 2 tablets per day, and 30 days have passed since your last refill:

Days Left = (90 × 2) - (30 × 2) = 180 - 60 = 120 days

This means you have 120 days of medication left before you need to refill your prescription.
