🧻 Toilet Paper Calculator
Estimate how long your toilet paper stock will last based on household size and usage habits.
What this calculator does
The Toilet Paper Calculator estimates how many days your current supply will last, and how many rolls you’ll need to buy over time, based on your household size and typical usage.
How it works
Enter how many people live in your household, how many rolls you currently have, how many sheets are on each roll, and typical bathroom habits (visits per person per day and sheets used per visit). The calculator multiplies these together to find your household’s daily sheet usage, then divides your total sheets on hand by that daily rate to estimate how many days your supply lasts.
Actual usage varies by household, roll size, and habits, so treat this as a general planning estimate rather than an exact figure.
