How to Calculate the Cost per Roll of Toilet Paper?

To find out the cost per roll of toilet paper, you can use the following formula:

Cost per Roll (C) is calculated as:

§§ C = \frac{P}{R} §§

where:

  • § C § — cost per roll
  • § P § — pack price (total cost of the pack)
  • § R § — number of rolls in the pack

This formula allows you to determine how much you are spending on each individual roll of toilet paper.

Example:

Pack Price (§ P §): $10

Number of Rolls (§ R §): 12

Cost per Roll:

§§ C = \frac{10}{12} \approx 0.83 §$

Additional Calculations

You can also calculate the total number of uses you can get from the pack based on the number of sheets per roll and sheets used per use:

Total Uses per Pack (U) is calculated as:

§§ U = \frac{S \times R}{S_u} §§

where:

  • § U § — total uses per pack
  • § S § — sheets per roll
  • § R § — number of rolls in the pack
  • § S_u § — sheets used per use

Example:

Sheets per Roll (§ S §): 200

Sheets Used per Use (§ S_u §): 2

Total Uses per Pack:

§§ U = \frac{200 \times 12}{2} = 1200 § uses

When to Use the Cost per Roll of Toilet Paper Calculator?

  1. Budgeting: Understand how much you are spending on toilet paper and adjust your budget accordingly.

    • Example: If you notice that the cost per roll is higher than expected, you might consider switching brands or buying in bulk.

  2. Comparative Shopping: Compare different brands or pack sizes to find the best deal.

    • Example: You can compare the cost per roll of a 12-pack versus a 24-pack to see which offers better value.

  3. Household Planning: Estimate how long a pack of toilet paper will last based on your household’s usage.

    • Example: If you know how many sheets your family uses daily, you can calculate how many days a pack will last.

  4. Sustainability Considerations: Evaluate the cost-effectiveness of eco-friendly options.

    • Example: Compare the cost per roll of standard toilet paper versus recycled or bamboo options.
