How Rent Splitting Works

By Room Size

Each person pays proportionally based on their room's square footage. Master bedroom pays more, smaller room pays less.

By Income

Each person pays a percentage based on their income proportion. Higher earner pays more — equitable, not equal.

Custom %

Set any custom split. Perfect when you've already agreed on specific percentages (e.g., 55/45).
