Free renter tools & calculators
Page last updated: August 22, 2026 · How we source & update
Four free calculators: rent affordability, the income a given rent usually requires, splitting rent between roommates, and a rental-scam red-flag checker. Each shows its formula and its limits on the page. Nothing you type is stored or sent anywhere, and no result determines your legal rights or what any landlord must accept.
Quick, free tools for renters — rent affordability, income to rent, splitting rent, and a rental-scam checker. Nothing you enter is stored.
All renter tools
Rent affordability calculator
How much rent can you afford? Enter your income to see a budget-friendly rent range using the common 30% guideline. A budgeting tool, not financial advice.
Income needed to rent (3× rent calculator)
Many landlords look for income of about 3× the monthly rent.
Rent-split calculator for roommates
Split rent fairly with roommates — evenly, or in proportion to each person's income.
Rental scam checker
Is this rental a scam? Check the red flags — wire transfers, below-market rent.
