About this template
A rental property can look great on a listing and lose money in practice. This calculator helps you run the numbers on a specific deal before you commit, using your own estimates for financing, rent, vacancy and every operating cost.
Enter the purchase and loan details, expected income and expenses, and the workbook calculates the monthly mortgage payment, gross and effective income, operating expenses, net operating income, annual cash flow, cash-on-cash return, cap rate and break-even occupancy — with a one-page summary dashboard. Try pessimistic scenarios too: real costs and returns can differ substantially.
