# Toilet Paper Calculator

Calculate how long your toilet paper will last. Enter rolls, household size, and usage to see days of supply, weekly consumption, and estimated run-out date.

## What this calculates

How long will your stash last? Enter the number of rolls you have, your household size, and average usage to find out exactly when you will need to restock. No more guessing at the store about whether 24 rolls is enough.

## Inputs

- **Rolls on Hand** — min 1, max 500 — Standard single rolls (not mega or double)
- **Roll Type** — options: Standard (200 sheets), Double (400 sheets), Mega (1000 sheets)
- **People in Household** — min 1, max 20
- **Sheets Per Use (average)** — min 5, max 50 — Average sheets per bathroom visit (typical: 15-25)
- **Uses Per Person Per Day** — min 1, max 15 — Average bathroom visits per person per day

## Outputs

- **Days of Supply**
- **Weeks of Supply**
- **Estimated Run-Out** — formatted as text — Approximate date your supply runs out
- **Household Sheets/Day**
- **Rolls Per Week**

## Details

The average American uses about 100 rolls of toilet paper per year, which comes out to roughly 2 rolls per week. A household of 4 goes through about 8 rolls per week with standard rolls.

Roll size comparison:

  - Standard roll: About 200 sheets, 150-200 uses

  - Double roll: About 400 sheets, equal to 2 standard rolls

  - Mega roll: About 1,000 sheets, equal to 5 standard rolls

To save money, compare the price per sheet rather than price per roll, since roll sizes vary wildly between brands. A "mega" 6-pack may actually be cheaper per sheet than a "standard" 12-pack.

## Frequently Asked Questions

**Q: How many rolls does the average person use per week?**

A: The average person uses about 1.5 to 2 standard rolls per week. This varies based on the number of bathroom visits (typically 6-8 per day) and sheets per use (typically 15-25 sheets). Women generally use more than men because they use toilet paper for every bathroom visit.

**Q: What is the difference between double and mega rolls?**

A: A double roll has about twice the sheets of a standard roll (400 vs 200), while a mega roll has about five times the sheets (1,000 vs 200). When comparing prices, always look at the price per sheet or the equivalent standard roll count to make a fair comparison.

**Q: How much toilet paper should I keep in stock?**

A: A good rule of thumb is to keep at least 2 weeks of supply on hand. For a household of 4, that is roughly 16 standard rolls (or 4 mega rolls). Buying in bulk when prices are low is the most cost-effective approach.
