Cap Rate Formula Calculator

The Cap Rate Calculator (Capitalization Rate Calculator) is a powerful real estate investment tool designed to help investors quickly evaluate the profitability of a property. It calculates two essential metrics:

• Net Operating Income (NOI)
• Capitalization Rate (Cap Rate)

These values are critical in determining whether a property is a good investment. Instead of manually crunching numbers, this tool automates the process, giving you fast, accurate insights based on your inputs.

Whether you’re a beginner investor, real estate analyst, or property manager, this calculator simplifies financial decision-making and helps you compare investment opportunities with confidence.

What Does the Cap Rate Calculator Do?

This tool evaluates real estate performance using three key inputs:

• Property Value
• Annual Rental Income
• Annual Operating Expenses

From these values, it calculates:

• Net Operating Income (NOI) = Rental Income − Expenses
• Cap Rate (%) = (NOI ÷ Property Value) × 100

The results help you understand how efficiently a property generates income relative to its price.

Practical Example of Cap Rate Calculation

Let’s say you are evaluating a rental property:

• Property Value: $500,000
• Annual Rental Income: $60,000
• Annual Expenses: $15,000

Step-by-step calculation:

• NOI = 60,000 − 15,000 = $45,000
• Cap Rate = (45,000 ÷ 500,000) × 100 = 9%

Final Result:

• Net Operating Income: $45,000
• Cap Rate: 9%
• Property Value: $500,000

Interpretation:

A 9% cap rate generally indicates a strong investment opportunity, depending on location and market conditions.
