By inputting key metrics like purchase price, rental income, expenses, and financing terms, you can quickly assess whether an investment is financially sound.
How the Calculator Works

- Net Operating Income (NOI): Rental income minus operating expenses
- Cash Flow: NOI minus mortgage payments
- Return on Investment (ROI): Annual cash flow divided by total investment
- Capitalization Rate: Annual NOI divided by property value
- Debt Service Coverage Ratio: NOI divided by mortgage payments
The calculator assumes standard Australian property investment practices and tax considerations. All calculations are based on the inputs you provide and the assumptions shown in the calculator panel.

Interpreting Results
When reviewing your investment results, consider these key metrics:

Example: A property with $500,000 purchase price, $30,000 annual rental income, $15,000 annual expenses, and 20% down payment might show:
- NOI: $15,000
- Cash Flow: $12,000
- ROI: 12%
- Capitalization Rate: 6%
- Debt Service Coverage Ratio: 1.5
This suggests a solid investment with good returns and manageable debt levels.
