With our toothpaste calculator you can check a durability and cost of your toothpaste.

If you brush your teeth twice a day, every single day (and we hope you do) you definitely run out of toothpaste every couple months tops. No one likes when it's over, especially when you have no backup option in place. That's why we built this simple calculator to help you estimate the durability of your toothpaste. In order to get your result you'll need to insert the following values:

  • Toothpaste capacity - the volume of the container, so how many milliliters/fluid ounces fit in a tube
  • Wastage - amount of toothpaste that stays inside the tube even though you're trying to squeeze it out so hard (sometimes it just won't work without cutting the thing open)
  • Pea-sizes of toothpaste - 1 pea-size is the recommended amount of toothpaste you should use with every wash. Don't trust those commercials that suggest at least triple this - most stomatologists agree one pea-size is perfectly enough.
  • Daily brushes - how many times you brush your teeth every day (please say it's at least two)
  • People in household - how many people you share your toothpaste with
  • Toothpaste price - how much will a single tube of toothpaste cost you

That's it. The tool will instantly tell you how long the toothpaste will last for given the values you entered. Treat it as an approximate value of course but it should give you some general idea about the durability or the toothpaste and its cost.
