What is this calculator?
This calculator estimates your lifetime toilet paper use. Enter how many rolls your household gets through per person each month, your age and your expected lifespan, and it shows rolls per year, rolls still ahead of you and the full lifetime total. Handy for bulk-buying decisions or a very practical dinner-party statistic.
How does it work?
Rolls per month are multiplied by twelve for a yearly figure, then by your age for the total so far and by your remaining years for what is left. Roll sizes, sheet counts and household habits vary widely, so treat the number as a ballpark.
Frequently asked questions
How many rolls does one person use?+
Estimates usually land between three and six rolls a month per person, depending on roll size and household habits.
Should I enter household or personal rolls?+
Enter your personal share. Divide the household total by the number of people living there.
Do roll sizes matter?+
A lot. Mega rolls can hold three or four times the sheets of a standard roll, so adjust your monthly number accordingly.
Why default to 80 years?+
It is close to average life expectancy in high-income countries. Change it to any figure you like.
How accurate is this?+
It is a rough estimate from a steady monthly average, useful for perspective rather than precise stockpiling.
