How to use this calculator
- Enter the total monthly rent for the apartment/house.
- Select the number of roommates.
- Toggle whether rooms are equal size or if someone has a premium room (like an en-suite).
- Add any shared monthly bills (internet, utilities, streaming).
What your results mean
The fairest way to split rent is usually separating the 'common space' (split equally) from the 'bedroom space' (split by square footage). We use a simplified premium model: the person with the master bedroom pays a set percentage more, and bills are split evenly.
5 tips for sharing finances with roommates
- Put the agreement in writing before anyone signs a lease or moves a single box.
- Use apps like Splitwise to easily track shared expenses like groceries or toilet paper.
- Ensure all roommates are on the official lease if possible, to protect everyone legally.
- Set a firm rule on when the Venmo/Zelle transfers must happen (e.g., 3 days before rent is due).
- If couples share a room, they should pay a larger share of utilities and common space, but not necessarily 2x the bedroom cost.
