Frequently Asked Questions
What does a Rental Property Calculator do?
It estimates rental performance using your inputs like purchase price, rent, loan details, taxes, insurance, maintenance, and vacancy. It helps you understand cash flow and basic return metrics before buying.
What inputs should I include for realistic results?
Include mortgage payment, property taxes, insurance, maintenance, vacancy rate, property management, HOA (if any), and repairs. Missing expenses is the #1 reason rental returns look unrealistically high.
What is cash flow and why does it matter?
Cash flow is what's left after rent minus all monthly costs. Positive cash flow means the property pays for itself. Negative cash flow means you'll cover the gap every month.
Is ROI the same as cash flow?
No. ROI looks at overall return relative to your investment, while cash flow is monthly money in vs out. A property can have low cash flow but strong long-term returns, or vice versa.
Is this Rental Property Calculator safe to use?
Yes. It runs 100% client-side, so your financial inputs are processed in your browser and never uploaded to a server.
