Details for this calculator
(1) The average number of visits to a bathroom per day in the U.S. ranges between 4 and 10, across an average household size of 2.61 on a range between 1 and 5.

(2) The toilet paper product data was based on the most popular toilet paper brand in 2022:

• 86.27 million customers
• 264 sheets per “mega” roll
• 24 rolls per pack
• $24.98 per pack
• $1.04 per roll
• 0.38 cents per sheet

(3) The industrial resource cost to produce 1 single roll of toilet paper is 1.5 pounds of wood, 37 gallons of water, and 1.3 kilowatt/hours (KWh) of electricity.

(4) A conservative assumption on toilet paper consumption was used. Non-bidet owners average around 16 sheets per trip (4 wipes per trip and 4 sheets per wipe), whereas bidet owners average around 4 sheets per trip (2 wipes per trip and 2 sheets per wipe).

How to calculate your savings

(1) Multiply household size, average toilet visits per day (per person), average wipes per visit (per person), and average toilet sheet used per wipe (per person). This will give you the average total number of toilet paper sheets used per day.

(2) Multiply the average total number of toilet paper sheets used per day, the number of days in a year, and the per sheet cost of the toilet paper brand you use*. This will give you the total cost of your toilet paper usage per year.

(3) After calculating the total toilet paper usage per year of both a non-bidet owner and a bidet owner, calculate the difference between the two. This will give you the total savings per year in dollars and toilet paper rolls (or just use our friendly calculater above!).

*To get the toilet paper brand’s cost per sheet, first divide the total number of rolls by the total cost. This will get you the cost per roll. Then take the cost per roll and divide it by the number of sheets per roll.
