How to Use Toilet Paper Calculator
The Toilet Paper Calculator keeps your bathroom stocked without panic-buying.
- Pick a household preset — Solo, couple, family of 3 or 5.
- Adjust people, sheets per roll and sheets per person per day.
- Enter rolls in stock — Count what’s already at home.
- Set a target coverage in days — Such as 30 or 90.
- Set price per roll.
- Read days available, daily consumption, rolls needed and restock cost.
Formula & Theory — Toilet Paper Calculator
dailyConsumption = people × sheetsPerPersonPerDay
sheetsAvailable = rolls × sheetsPerRoll
daysAvailable = sheetsAvailable / dailyConsumption
requiredRolls = ceil(targetDays × dailyConsumption / sheetsPerRoll)
extraRolls = max(0, requiredRolls − rolls)
restockCost = extraRolls × pricePerRoll| Symbol | Meaning |
|---|---|
| sheetsPerPersonPerDay | Average household usage per person |
| sheetsPerRoll | Sheets in a single roll |
| rolls | Rolls currently at home |
| targetDays | Coverage period to plan |
The Toilet Paper Calculator uses ceiling rounding so a 1.1-roll need still gives you 2 rolls, never short.
