By inputting key data such as property price, rental income, monthly expenses, and mortgage payments, this tool provides instant insights into your potential investment returns.
Whether you are analyzing your first property purchase or managing a growing portfolio, this calculator simplifies financial planning and helps you make informed investment decisions.
How the Rental Property Calculator Works
The calculator evaluates your rental property performance based on four main inputs:
- Property Price – The total cost to purchase the property.
- Monthly Rental Income – The expected rent you will receive each month.
- Monthly Expenses – Regular costs such as property management, maintenance, insurance, and utilities.

- Annual Cash Flow – Total cash earned in a year.
- Cash on Cash Return (CoC) – The return on your cash investment, expressed as a percentage.
This allows investors to quickly assess whether a property is financially viable and compare multiple investment options.
