A Rental Property ROI Calculator evaluates the financial viability and cash flow potential of residential and commercial real estate investments.
Core Performance Metrics: Net Operating Income (NOI) = Gross Rental Income − Operating Expenses (Property Taxes, Insurance, Maintenance, Management, Vacancy Reserves). Capitalization Rate (Cap Rate) = (Annual NOI / Property Purchase Price) × 100. Cash-on-Cash Return (%) = (Annual Net Cash Flow / Total Cash Invested) × 100.
Leverage Dynamics: Using mortgage financing introduces leverage, which can amplify cash-on-cash returns when rental income comfortably exceeds ongoing debt service.
Reserve Planning: Setting aside 5%–10% of monthly gross rent for maintenance and vacancy reserves ensures long-term cash flow stability and protects against unexpected repair costs.
How is Net Operating Income (NOI) calculated for rental property?
Subtract all operating expenses (taxes, insurance, repairs, property management, vacancy) from gross rental revenue, excluding mortgage debt payments.
