Early Refill Calculator
Fully functional
Enter up to 2 prior fills, oldest to newest. "Date Filled / Days Supply" above is treated as the current (most recent) fill. Only fills within 4 months of the current fill count toward Cumulative Days Early — older fills are excluded automatically.
Outside the 4-month lookback window — excluded from Cumulative Days Early.
Outside the 4-month lookback window — excluded from Cumulative Days Early.
