What is a Rental Property Calculator?

A rental property calculator evaluates the financial performance of real estate investments. It computes cash flow, capitalization rate, cash-on-cash return, and gross rent multiplier to help investors compare properties and make informed decisions.

Cap rate measures unlevered return using net operating income, while cash-on-cash return focuses on the actual cash invested. These metrics together provide a comprehensive view of a property's profitability.

Frequently Asked Questions

What is a good cap rate?

A good cap rate varies by market, but many investors target 4% to 10%. Higher cap rates indicate higher potential returns but may come with higher risk.

How is cash-on-cash return different from cap rate?

Cap rate ignores financing and uses purchase price. Cash-on-cash return measures annual cash flow against your actual cash invested (down payment and closing costs).

What is gross rent multiplier?

GRM divides the purchase price by annual gross rent. A lower GRM generally indicates a better value, with many investors seeking properties under a GRM of 10.

Does this calculator account for closing costs?

No, closing costs are not included. For a more precise cash-on-cash return, add closing costs and repairs to your down payment input.
