Deodorant Stick Lifespan Calculator: Never Get Caught Without It

Deodorant sticks run out at a predictable rate based on how much product you apply and how often. This calculator estimates the number of days a stick will last so you can restock ahead of time.

The Formula

Days Lasting = Stick Weight / (Grams per Application × Applications per Day)

Worked Example

A 75-gram stick, using 0.5 grams per application, applying once a day.

Days Lasting = 75 / (0.5 × 1) = 150 days

How to Use This Calculator

1. Enter the deodorant stick's net weight in grams.
2. Enter roughly how many grams you use per application.
3. Enter your applications per day.
4. Click Calculate to see how many days the stick will last.
