Fair Divider: Rent Splitter

Roommate Expense Calculator

Free · Designed for iPad. Not verified for macOS.

Split rent or a shared stay fairly with the people you live with — one room at a time. Fair Divider is a rent splitter built for roommates, flatmates, and housemates who want to split rent, split bills, or split shared costs without an argument. Everyone privately says how much each room is worth to them, and the app works out exactly what each person owes for the room they end up with — so nobody would rather have someone else's room at that person's price. WHY IT'S FAIR • Envy-free by design: every participant ends up preferring their own room and their own price to anyone else's. That's a stronger guarantee than just splitting the total rent equally. • No manual math: the app does the arithmetic for the whole group — no spreadsheets, no back-of-the-envelope guessing. • Any group size: works for two roommates or a ten-person shared house. • Rent or a stay: monthly rent in an apartment, or the cost of a vacation rental split between friends. WHO USES A RENT SPLITTER LIKE THIS • New roommates moving into an apartment where rooms differ in size, light, or bathroom access. • Flatmates renewing a lease and re-splitting rent now that room sizes or a housemate has changed. • Housemates in a shared house dividing bills and rent room by room instead of guessing. • Friends or family sharing a vacation rental, splitting the cost of a house by who gets which room. • Couples or siblings dividing a shared living cost or an inherited property fairly. HOW IT WORKS 1. Add the people and the rooms (or shares) you're dividing, and the total rent or cost. 2. Each person privately states what every room is worth to them. 3. Fair Divider computes a division where each person's price for their own room is one they wouldn't trade for anyone else's. 4. Everyone sees the final split and knows exactly what they pay. ONE PHONE, OR EVERYONE'S OWN Pass a single phone around the table to enter preferences one by one, or start a shared division and have everyone join instantly from their own phone by scanning a QR code. That makes it easy to split rent or a shared stay even when your roommates or flatmates aren't all in the same room. BUILT FOR REAL SHARED LIVING Whether you're working out rent for a new apartment, re-splitting bills after a roommate moves out, or figuring out who pays what for a weekend rental, Fair Divider turns a fairness argument into a two-minute calculation. No more "your room is bigger" or "mine doesn't have a window" — the numbers settle it, and everyone can see why the split is fair. PRIVATE, FREE, AND SIMPLE • Free to use, no account required. • No ads, ever. • Nothing to install for the rest of the group — just share a link or a QR code. • Light and dark theme. • Available in 9 languages, so international roommates and flatmates can each use the app in their own language. Whether you call it a rent splitter, a rent calculator, a bill splitter, or just "the app that finally settled how we split the rent," Fair Divider gives every roommate, flatmate, and housemate a price they're genuinely happy with.
