How do you calculate rent?

Renters can quickly calculate how to split rent among roommates by using the Splitwise online rent calculator, according to the company website as of 2015. The online calculator displays a few questions about the rooms and divvies up the rent so that each person knows the amount of his share.

After answering a few questions about common areas, the final step is to click Calculate and see each roommate's rent, according to Splitwise.
