About Renter Numbers
Renting comes with enough uncertainty. The math should not.
Renter Numbers creates free, transparent calculators for apartment decisions. Every tool shows its formula, assumptions, and limits without requiring an account or collecting raw calculator inputs.
Built for the decision in front of you
People use Renter Numbers to compare prorated rent methods, estimate move-in cash, test affordability, budget utilities, split roommate rent, and plan a move. The site is independent from LeaseGuard, with a limited referral when the next question depends on actual lease language.
Our standard
Calculators should make uncertainty visible. We separate arithmetic from legal conclusions, identify important assumptions, date substantive reviews, and provide a corrections channel.
