If your share meals and grocery expenses with your roommates, here is a method to do your accounts without headache while remaining fair.

Count the number of meals

Using a spreadsheet, create a table that allows you to track the number of meals taken by each one, over a given period. Print it and pin it on your fridge. Then, at each meal, put a cross for the present people. If a roommate invites external people, add extra crosses to this roommate.
