Routine cost calculator

How long a bottle lasts and what the routine costs per day, from dose and container size.

Formula

days per container = container size (ml) / (dose in ml x applications per day); cost per day = price / days per container

A pump or dropper dose is assumed constant. Real doses vary, and a pea-sized amount is roughly 0.25 ml.
Product left in the container at the end, and product discarded after its period-after-opening date, are not counted.

Dose is the biggest variable and the one the label rarely states in millilitres.
