Prescription Refill Calculator

Never run out of meds again — see exactly when your supply runs out, when to call the pharmacy, and what it costs per month.

Pills / units on hand

Count what you actually have left today.

Units per day

e.g. 2 pills once daily = 2.

Price per unit (optional, $)

Your copay per pill / unit.

Refill lead time (days)

Pharmacy + insurance usually takes 1–3 days.

📞 Refill reminder
