About Our Rental Property Calculator

Our rental property calculator is designed to help real estate investors quickly evaluate the financial performance of a rental property.

How the Rental Property Calculator Works

The calculator is simple to use—just enter the financial details of your rental property, and it will instantly generate the proforma numbers you need to make informed investment decisions.

Step 1: Enter Rental Income

Start by inputting your monthly rent and any additional yearly income sources (such as laundry, parking, or pet fees). The calculator will compute your potential rental income and adjust for vacancy rate to show your effective gross income—the actual revenue you can expect to collect.

Step 2: Account for Operating Expenses

Every rental property comes with costs. Enter your estimated expenses, including:

Property Taxes

Insurance

Maintenance

Management Fees (if applicable)

Reserves for Replacement (setting aside funds for future repairs)

Other Expenses (utilities, legal fees, etc.)

The calculator will total your expenses so you can see how much of your rental income goes toward covering costs.

Step 3: Calculate Net Operating Income (NOI)

Your NOI is the rental income left after expenses but before mortgage payments. This figure is critical for evaluating the property’s financial performance.

Step 4: Consider Investment & Financing Costs

If you’re buying a property, enter details like:

Purchase Price

Closing Costs

Renovation Costs

The calculator will show your total investment cost and calculate key financing metrics, such as:

Loan-to-Cost Ratio

Loan Interest Rate

Loan Amortization Period

Step 5: Review Investment Metrics

Once all inputs are in, the calculator will provide key investment indicators:

Going-in Cap Rate – Measures the property’s expected return based on NOI and purchase price.

Unlevered Yield on Cost – Evaluates profitability before financing.

Cash-on-Cash Return – Assesses the return on your initial investment after debt service.
