A fair, envy-free way to split rent 9 ways
To split rent 9 ways fairly, price each of the 9 rooms separately instead of dividing the total into 9 equal shares, so nobody would rather swap into someone else's room at the rent that person pays.
Splitting rent 9 ways sounds simple — divide the total by 9 — but it rarely is. When 9 roommates share a home, the rooms are almost never equal: one is larger, one has an en-suite bathroom, one is quieter. Dividing the rent into 9 equal shares ignores those differences and usually leaves at least one person feeling they overpaid. This free calculator splits rent between 9 roommates fairly instead, pricing each room so that the result is envy-free.
Envy-free means that once the calculator decides who takes which room and what each of the 9 participants pays, nobody would rather swap into someone else's room at the rent that person is paying. The amounts always add up exactly to your total, to the cent.
To split rent 9 ways, enter the total, name the 9 rooms and the 9 participants, and let each person pick their preferred room as the prices adjust. It takes about two minutes, needs no account, and there is no tracking.
By nine people the rent is large enough that a few percent is real money to each of them every month. Rounding the total into nine equal parts hides differences of a hundred euros or more between rooms that nobody would accept if they were stated out loud. Pricing each room states them out loud, once, and then the question is closed.
