About

Splitting up shared costs can be a nightmare. Just 4 friends on a night out may end up passing money between them 10 times back and forth - and that's assuming everyone got change! Settling costs for 8 people requires up to 36 exchanges - with more than 100 possibilities to do them!

PotSplitter is the world's first tool to find the optimal way to divvy up shared costs. Developed by researchers and mathematicians at the Swiss Federal Institute of Technology, it reliably calculates the best way of who should pay back who.

You can split up costs after a night out with your friends, a week-end get away or a 2 month trip. All you need is a track of the expenses you want to divide - be it on random scraps of paper or directly tracked online using PotSplitter from your computer or your phone.
