Rental Property Calculator

This calculator works out what a rental property leaves in your pocket once the mortgage is paid. Enter the purchase price and financing, the rent, a vacancy allowance and the running costs, and it returns monthly and annual cash flow, cash on cash return, cap rate and debt service coverage, with every expense line printed. Net operating income and the cap rate leave the loan out, because they measure the building rather than how you paid for it, while cash flow and cash on cash return include it because that is what actually arrives. Maintenance, the capital reserve and management are taken as percentages of collected rent, so they describe an average year rather than the month the boiler fails. It does not count income tax, depreciation, appreciation, the equity gained as the loan is paid down, or mortgage insurance on a small down payment.
