A rental property can generate income, build equity, and provide long-term growth, but only when the numbers support the investment. The Rental Property ROI Calculator helps investors evaluate a property before making a purchase decision. It combines purchase details, financing, rental income, vacancy, and operating expenses to produce a clear investment summary.
Enter the property price, down payment, closing costs, initial repairs, interest rate, and loan term. Then add the expected monthly rent, other income, vacancy rate, taxes, insurance, HOA charges, maintenance, management fees, and other recurring expenses. The calculator instantly estimates the mortgage payment, effective rental income, operating costs, net operating income, monthly cash flow, and annual cash flow.
The report also calculates important investment metrics, including cap rate, cash-on-cash return, gross rental yield, operating expense ratio, debt service coverage ratio, and estimated first-year ROI. These results make it easier to compare multiple rental properties using the same assumptions.
This calculator is useful for new landlords, experienced real estate investors, property managers, financial planners, and anyone considering a buy-to-let property. Values can be adjusted to test different rent levels, vacancy rates, financing terms, and expense estimates. The printable report provides a convenient summary for personal records or discussions with lenders, partners, and real estate professionals.
How to Use:
Enter the purchase price and planned down payment first. Add closing costs and any repairs required before renting the property. Provide the mortgage rate and loan term, followed by the expected rent and other monthly income. Enter the vacancy allowance and all operating expenses. The calculator updates automatically, or you can press Calculate. Review the cash flow, cap rate, cash-on-cash return, NOI, DSCR, and ROI estimates.

Property Snapshot
What is cash-on-cash return?
Cash-on-cash return compares annual pre-tax cash flow with the total cash invested in the property, including the down payment, closing costs, and initial repairs.
What is the difference between cap rate and ROI?
Cap rate measures property performance before mortgage payments, while ROI may include financing, cash flow, and estimated appreciation.
Does the calculator include vacancy?
Yes. The vacancy rate reduces expected rental income before calculating operating income and returns.
What expenses should be included?
Include taxes, insurance, HOA charges, maintenance, management fees, utilities paid by the owner, and other recurring costs.
Can I use this for multiple properties?
Yes. Enter each property's figures separately and compare the resulting cash flow, cap rate, and cash-on-cash return.
