Fairness is a funny thing. One person’s fair is another person’s rip-off. So it is important for a rent-splitting calculator to jive with a broadly intuitive sense of fairness. It can’t just be what I think is fair – or what any one person thinks – or it won’t be useful.
In order to validate and calibrate the formula I used for the rent-share calculator on this blog, I did a rather in-depth survey on “apartment sharing fairness” with my friends. Here are the results – enjoy!
