Calculate toilet paper cost per sheet and per roll from the pack price, roll count and sheets per roll, to see which pack is the better value.

Printed on the pack. Leave blank to get the cost per roll only.

Optional ply and sheet size
Adds cost per ply-sheet (one layer of one sheet).

Enter length and width to compare packs by area.

Toilet Paper Value Formula

The following equation calculates purchase cost per sheet. It does not assign a quality or market-value rating.

CPS = TC / (NR × SR)
  • Where CPS is the purchase cost per sheet (USD/sheet)
  • TC is the nonnegative package price in USD
  • NR is the positive whole-number roll count
  • SR is the positive whole-number sheet count used for every roll

To calculate cost per sheet, divide package price by rolls × sheets per roll. A zero price represents a free pack. Optional ply is omitted when blank; total ply-sheets = total sheets × ply, and cost per ply-sheet = price ÷ total ply-sheets. Enter both dimensions or neither: rectangular sheet face area is length × width, and total face area is that area × total sheets without multiplying by ply. Cost per square foot is price ÷ total face area. Square feet per USD is total face area ÷ price only for a positive price; it is undefined for a free pack. One inch is exactly 2.54 cm and one square foot is 144 square inches.

What is a Toilet Paper Value?

Definition:

This calculator reports unit purchase costs from the entered package price and quantities. Compare the same unit and a consistent price basis across packs. Cost per sheet, ply-sheet or area does not by itself establish quality, absorbency, strength, comfort or sheets needed per use.

How to Calculate Toilet Paper Value?

Example Problem:

The following example calculates cost per sheet; optional ply and dimensions are not needed for this result.

First, determine the number of rolls. In this example, there were 10 rolls.

Next, determine the sheets per roll. Each roll contains 200 sheets.

Next, determine the total cost. These rolls cost $20.00 in total.

Finally, calculate the cost per sheet using the formula above:

CPS = TC / (NR * SR)

CPS = $20 / (10 × 200) = $0.01 per sheet

FAQ

How can I find the best deal on toilet paper?

Divide each pack’s price by its total sheets and compare the same unit. If sheet sizes differ, compare cost per area using both dimensions as well. Use consistent discounts, taxes and delivery charges. Actual sheets needed per use and product preferences are separate considerations that this calculator does not estimate.

Does ply or thickness affect value?

Ply counts layers per sheet. Cost per ply-sheet is price divided by sheets × ply, but equal ply-sheet counts do not establish equal absorbency, strength, material amount or quality. Ply does not multiply the finished sheet’s face area; compare actual product characteristics separately.

Are bulk packages always cheaper?

No. A larger pack does not guarantee a lower unit price. Compare the actual price and quantities of the packs available to you, using cost per sheet or the same area unit rather than pack size alone.
