How the Rental Real Estate Calculator Works
The calculator focuses on four main inputs:

- Monthly Rental Income – Expected rent you can charge tenants each month.
- Monthly Expenses – Property-related costs including mortgage, maintenance, taxes, and insurance.
- Down Payment – Initial payment you make to purchase the property.
Based on these values, the tool calculates:
- Monthly Cash Flow – Rental income minus monthly expenses.
- Annual Cash Flow – Monthly cash flow multiplied by 12 months.
- Annual Rental Income – Total yearly income generated from rent.
- Cash-on-Cash Return (CoC) – Annual cash flow divided by your initial investment, expressed as a percentage.
By using these results, investors can quickly assess whether a property meets their financial goals.
