Thu, 09 Jul 2026 10:00:00 +0530

Splitting rent with roommates is where a lot of shared-flat friction starts, because splitting it equally is only fair when the rooms are equal, and they rarely are. This free calculator splits the rent by room size, adds a premium for a private bathroom, can weight by income instead, and splits your shared utilities too, so everyone sees a number they agree is fair. It works in any currency.

TL;DR: Enter the total rent, add each roommate with their room size (or income), tick anyone with a private bathroom and set a premium, and add your monthly utilities. The calculator shows each person’s fair monthly share, rent plus an equal split of utilities, updating live.
