How to Use This Calculator
Count your household
Include roommates, kids, or anyone regularly using your bathrooms. Guest bathroom usage can be tracked separately.
Estimate habits
Log daily bathroom visits and sheets per use for a few days. Different ages and routines can vary widely.
Plan shopping frequency
Use the supply days to schedule restock reminders before running low. Track sales to buy multi-packs when prices dip.
Formula
Sheets/Day = Members × Uses × Sheets/Use
Rolls/Day = Sheets/Day ÷ Sheets/Roll
Days of Supply = (Rolls on Hand × Sheets/Roll) ÷ Sheets/Day
Cost/Week = Rolls/Week × Cost/Roll
Example: 3 people × 4 uses × 7 sheets = 84 sheets/day. 350-sheet rolls last ~4.2 days each. A 24-pack lasts ~100 days.
Stockpiling Tips
Avoid panic buys—understanding your consumption keeps shelves stocked for everyone and saves you storage space.
- Track average consumption monthly to spot changes in habits.
- Store rolls in a cool, dry place to maintain quality.
- Consider bidets or reusable cloths to cut sheet usage drastically.
- Share bulk orders with neighbors to reduce cost and storage needs.
Frequently Asked Questions
How do quilted vs. thin sheets affect the math?
They primarily change sheets per use. If you double up on thinner paper, increase sheets per trip.
What about partial rolls?
Estimate the remaining fraction (e.g., half roll ≈ 0.5) and add to rolls on hand.
Can I track multiple bathrooms?
Yes—duplicate the calculator for each bathroom or average usage across the household for simplicity.
How often should I revisit the numbers?
Quarterly updates capture lifestyle changes (working from home, travel, guests). Adjust when habits shift.
