Roommate Rent Calculator
Split rent with roommates — fairly, when the rooms differ
A roommate rent calculator works out how much each person pays when bedrooms are not equal, instead of splitting the total evenly and leaving whoever gets the smallest room short-changed. Each of two to ten roommates says what a room is worth to them, and Fair Divider prices the rooms so the split is envy-free, free and takes two minutes.
When roommates move in together, the bedrooms are almost never equal: one is larger, one gets the morning light, one is the box room next to the bathroom. Splitting the rent evenly ignores all of that and is the quiet source of a lot of roommate resentment. This free roommate rent calculator prices each room instead, so the split is envy-free — once it decides who pays what, no roommate would rather take someone else's room at the rent that person is paying.
It takes about two minutes. Enter the total rent, add each bedroom, add each roommate, and let everyone pick the room they prefer as the prices adjust. The split covers your full total — so the rent is covered and the split feels fair to everyone at the table.
There is no account to create, no ads and no tracking. Fair Divider works for two to ten roommates.
