📈 What Is a Capitalization Rate?
The Capitalization Rate is a percentage that indicates the expected annual return on an investment based on its net operating income (NOI) and current market value or purchase price. It provides a quick snapshot of profitability, helping investors compare different investment options.
Cap Rate Formula:
Cap Rate (%) = (Net Operating Income / Purchase Price) × 100
Where:
- Net Operating Income (NOI) = Total income – Operating expenses (excluding mortgage payments)
- Purchase Price = The current market value or cost of acquiring the property

🔧 How to Use the Cap Calculator
Using the Cap Calculator is quick and easy. Here’s how:
Step-by-Step Instructions:
- Enter Annual Rental Income – The total expected revenue from renting the property.
- Enter Operating Expenses – Include maintenance, management fees, taxes, insurance, and utilities (exclude loan payments).
- Enter Purchase Price or Market Value – The cost you paid or the current value of the property.

📊 Example Calculation
Let’s say:
- Annual Rental Income: $48,000
- Operating Expenses: $12,000
- Purchase Price: $450,000
Step 1: Calculate Net Operating Income
NOI = $48,000 – $12,000 = $36,000
Step 2: Calculate Cap Rate
Cap Rate = ($36,000 / $450,000) × 100 = 8%
Result: The Cap Rate is 8%, indicating a healthy return for a residential property investment.
