Expert Tip: Successful landlords typically aim for the “1% Rule”—where monthly rent equals at least 1% of the total purchase price—to ensure positive cash flow.

Determining the true profitability of a rental property requires looking beyond the monthly rent check to account for the full spectrum of ownership costs. Our Landlord Profit Calculator is a professional-grade financial tool designed to provide property owners with a crystal-clear view of their bottom line. By aggregating gross rental income and subtracting essential outlays—including mortgage interest, property taxes, insurance, maintenance reserves, and management fees—this calculator determines your actual Net Operating Income (NOI) and monthly net profit. Whether you are managing a single-family home or a multi-unit portfolio, understanding your “True Profit” is vital for assessing the viability of your investment and planning for future acquisitions. This utility also factors in a vacancy allowance to ensure your profit projections remain realistic in fluctuating markets. Built with a strict “privacy-first” architecture, all data processing occurs locally within your browser. This ensures that your sensitive financial records, property addresses, and income details never leave your device and are never stored on external servers. Gain the analytical clarity needed to manage your real estate business with 100% private, data-driven profit modeling and professional accuracy.
