Thanks to interest from readers and responders like you, I have had a lot more opportunity to check my original work and the calculator is holding up quite well under public scrutiny. Thanks to everyone who gave feedback or wrote notes of congratulations – it’s made this whole project really, really fun!
Right after launch, I started collecting voluntary feedback from people using the calculator. Originally, I simply asked people to rate the calculator on a 1-5 scale. Here are the results from the first 1,338 respondents (before I switched the feedback system to the present one, which is still collecting data).
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!
