Rent Split Calculator
Fair rent shares โ equal, by income, or by room size, honestly argued.
About this calculator
Total rent, your people, and one of three methods: equal, proportional to income, or proportional to room size. Add as many housemates as the lease holds; every share shows its amount and percentage.
Which split is actually fair?
All three survive scrutiny, for different houses. Equal is right when rooms and incomes are roughly level โ simplicity is itself a fairness feature. By income keeps rent the same share of everyone's pay (the argument: a 50/50 split of a $2,400 flat burdens a $2,000 earner four times as hard as a $6,000 one). By room size prices what's occupied โ master-with-ensuite versus box room is a real difference the rent should notice. The blend a thousand flat meetings converge on: start from room sizes, nudge for income, write the number down where everyone can see it. Utilities usually stay equal (usage doesn't track salary), and the percentage calculator referees any counter-proposals. Nothing you enter here leaves your browser.
Frequently asked questions
How do you split rent fairly with different incomes?
Proportionally: each pays rent ร their income รท combined income, keeping rent an equal share of everyone's pay. The calculator does it for any number of people.
Should the bigger room pay more?
Most long-running households say yes โ the room-size method prices the square metres each person actually occupies, which defuses the master-bedroom resentment before it starts.
How should utilities be split?
Usually equally regardless of the rent method โ consumption doesn't track salary or room size. Streaming subscriptions follow the same logic.
