Split rent by the rooms, not the headcount.
Room size, a private bath, a couple sharing, a parking spot, or bids for each room. Everyone sees the same maths, every amount says why, and the link goes straight into the group chat.
Kitchen, living room, shared bath. The rest of the rent follows each room.

The working, room by room
| Room | People | Weight | Shared part | Room part | Pays |
|---|---|---|---|---|---|
| Room A | 1 | 168 × 1.25 | $400.00 | $855.20 | $1,255.20 |
| Room B | 1 | 120 × 1 | $400.00 | $488.69 | $888.69 |
| Room C | 1 | 112 × 1 | $400.00 | $456.11 | $856.11 |
| Total | 3 | $1,200.00 | $1,800.00 | $3,000.00 |
Weight = floor area × the room’s multiplier (private bath and factors). Unrounded parts are shown; the “Pays” column is rounded to cents so it adds up exactly.
Pick the method that matches what you think is fair
By room
The shared rooms are split per person, and the bedrooms by floor area, with a multiplier for a private bath and small, agreed adjustments for closet, light and noise. A couple pays two shares of the shared space but one bedroom. Best for roommates whose rooms differ.
By income
Everyone pays the same share of what they earn, with an optional cap on the largest share. Most often chosen by couples and partners who pool their lives, less often between roommates.
Bid for rooms
Each person says what every room is worth to them. Rooms go where they’re valued most, at prices nobody would swap for (envy-free), with the worst-off person as well off as possible. Inspired by Spliddit; our own implementation.
Twenty situations, each with the numbers worked out
Each one opens the calculator pre-filled with sample numbers, the formula, and when that split is fair and when it isn’t.
