Free Cap Rate Calculator for Real Estate Investors

Cap rate, short for capitalization rate, is one of the most important metrics for evaluating rental properties and investment opportunities. It helps investors quickly understand how much income a property generates relative to its value.

What is Cap Rate?

Cap Rate (%) = (Net Operating Income ÷ Property Value) × 100

  • Net Operating Income (NOI): Total rental income minus all operating expenses.
  • Property Value: The purchase price or current market value of the property.

In simple terms, the cap rate shows you the percentage return you can expect if you bought the property outright.
