How long will your current toilet paper supply last?  Well there’s now a website to help you work that out.

At they’ve created a calculator to see just how far you could stretch your current supply if you haven’t already guestimated it yourself.

Simply select the amount of rolls you have and the amount of times you visit the toilet each day and the magic number of days will be revealed.   Advanced options include selecting the number of sheets used per visit and even the amount of sheets on each roll.

Now if you have more than enough…perhaps spare a few rolls for someone who doesn’t.
