A few months back, I posted about Harvard student Jonathan Bittner and his rent calculator, which can give you a good idea about how much your share of the rent will be using scientific formulas based on square footage and other aspects of the place you are sharing with others.
Jonathan has now released a new site, Splittherent.com that allows you to keep track of the rent and expenses for you and your roommates. This allows you to keep exact tabs on who owes what and why. No more grey areas and wondering why you’re short on your portion of the rent when you shouldn’t be. So check it out, and see if it makes your shared situation any easier.
