Period Products Cost Calculator
Estimates the annual and lifetime cost of period products based on your usage and product costs.
Period Products Cost Calculator gives you a faster way to work through practical calculation scenarios without rebuilding the same calculation from scratch every time. Start with Average Period Length (days), Days of Heavy Flow per Period, Pads/Tampons Used per Day (Heavy Flow), and Pads/Tampons Used per Day (Light Flow) and use the live outputs to estimate Total Pads/Tampons Used per Period, Total Pads/Tampons Used per Year, and Boxes of Pads/Tampons Needed per Year in one pass. This page is built to help you compare scenarios quickly, validate rough assumptions, and move into a related calculator when you need a second angle on the same problem.
