Rental Property Cap Rate Calculator
Results
In real estate investing, understanding a property’s profitability is essential before making any purchase decision. One of the most widely used metrics for evaluating investment performance is the Capitalization Rate (Cap Rate). It helps investors quickly assess the potential return on a rental property based on its income and market value.
The Rental Property Cap Rate Calculator is a simple yet powerful tool designed to automate this process. Instead of manually calculating income, expenses, and net operating income, investors can enter a few key values and instantly get accurate results.
This tool is especially useful for beginners and professional investors who want to compare multiple properties efficiently, reduce calculation errors, and make data-driven investment decisions.

Practical Example of Cap Rate Calculation
Let’s assume you are evaluating a rental property with the following details:
- Property Value: $250,000
- Monthly Rent: $2,000
- Vacancy Rate: 5%
- Monthly Expenses: $500
Step-by-step breakdown:
- Annual Rent (adjusted for vacancy):
$2,000 × 12 = $24,000
After 5% vacancy: $24,000 × 0.95 = $22,800 - Annual Expenses:
$500 × 12 = $6,000 - Net Operating Income (NOI):
$22,800 − $6,000 = $16,800 - Cap Rate:
($16,800 ÷ $250,000) × 100 = 6.72%
Result:
- NOI: $16,800
- Cap Rate: 6.72%
This helps investors quickly decide whether the property meets their investment goals.
