About RentalDealMath

We build free calculators that help everyday investors and landlords decide whether a rental property is worth buying.

Most rental calculators either hide the useful parts behind a sign-up or give you a wall of percentages with no explanation. RentalDealMath does the opposite: enter a property's numbers once and get a clear verdict, the reasons behind it, and what happens if things go worse than planned.

How we work

• Every calculator is free and works without an account.
• Calculations run in your browser, so the numbers you enter stay on your device.
• We show the formulas we use, so you can check the math yourself.

Important

Our tools give estimates based on the numbers you enter. They are not financial, tax or legal advice. Always confirm rents, taxes, insurance and financing locally, and speak with a qualified professional before buying a property.
