Formula Used in Adderall Refill Calculation
The calculator uses a simple time-based formula to estimate refill timelines.
1. Remaining Days Formula
Remaining Days = Days Supply − Days Used
If result is negative, it is adjusted to zero.
2. Refill Date Formula
Next Refill Date = Last Refill Date + Remaining Days
This calculates when the medication supply will run out.
3. Days Remaining from Today
Days Left = Refill Date − Current Date
This determines whether the refill is:
- Upcoming
- Due today
- Overdue
Refill Status Explanation
The tool provides a clear status based on time remaining.
1. Not Ready
If the refill date is in the future, your medication is still available.
2. Ready Today
If today matches the refill date, your prescription is due for refill.
3. Refill Overdue
If the refill date has passed, you are late in refilling your medication.
Example Calculation
Let’s understand how the calculator works with a real example.
Scenario:
- Last Refill Date: 2026-06-01
- Days Supply: 30 days
- Days Used: 5 days
Step 1: Remaining Days
30 − 5 = 25 days remaining
Step 2: Next Refill Date
June 1 + 25 days = June 26, 2026
Step 3: Days Left from Today
If today is June 29, 2026:
June 26 − June 29 = -3 days
Final Output:
| Field | Result |
|---|---|
| Next Refill Date | 2026-06-26 |
| Days Remaining | -3 days |
| Status | Refill Overdue |
