About

Rent Split Calculator is an independent, single-purpose tool: enter the rent and a few details about the household, and see what each person pays under four common methods. It is not affiliated with any landlord, letting agent, or property platform.

Everything runs locally in your browser — no accounts, no signup, and nothing you type leaves your device. No figure here is a legal or tenancy agreement; a rent split is whatever the people signing the lease agree to.

The site is maintained by a small team who have each paid the wrong share of a rent for months before noticing. If a calculation here disagrees with your own arithmetic, trust your arithmetic first and tell us second.
