Splitting costs equally among people with very different financial resources might not be the fairest way. Assuming everyone is putting in the same effort and having similar amounts of free time, it might be fairer to split costs proportional to income.

This app allows you to split an amount of money among several people proportional to the respective incomes. For more control, you can adjust the contribution percentages in case a simple split proportional to income does not seem fair to you.
