How to Use the Makeup Calculator

A Makeup Calculator estimates how long your makeup products will last based on how often you use them and how much product you apply each time.

What It Does:

This tool allows users to select a makeup product (e.g., foundation, lipstick, or mascara), enter how often they use it weekly, and how much they use each time. It then calculates how many weeks the product will last before it runs out.
