Net Operating Income (NOI): This is your total annual income after all operating expenses are paid, but before mortgage payments or taxes.
Note: A "good" cap rate typically ranges between 4% and 10%, depending on the market location and property type.
What is a Capitalization Rate (Cap Rate)?
The Capitalization Rate, or Cap Rate, is the most popular metric used by real estate investors to assess the profitability and return potential of a rental property. It represents the yield of a property over a one-year time horizon assuming the asset is purchased for cash (no debt).
How to Calculate Cap Rate for Rental Property
The formula for Cap Rate is straightforward but requires accurate data regarding your income and expenses. The formula is:
Cap Rate = (Net Operating Income / Current Market Value) × 100
Step-by-Step Calculation Example
Scenario: You are looking at a duplex priced at $500,000.
- Gross Annual Rent: $3,000/month × 12 = $36,000
- Operating Expenses: Property tax, insurance, and maintenance total $8,000 per year.
- Net Operating Income (NOI): $36,000 – $8,000 = $28,000
- Calculation: ($28,000 / $500,000) × 100 = 5.6%
In this example, the property has a Cap Rate of 5.6%.
Why Cap Rate Matters
Cap rates allow investors to compare different investment opportunities quickly. A higher cap rate generally implies a higher potential return but often comes with higher risk (such as a property in a declining neighborhood or an older building requiring significant upkeep). Conversely, lower cap rates usually indicate "safer" investments in high-demand "Class A" locations where property values are expected to remain stable or appreciate significantly.
Important Considerations
It is vital to remember that the Cap Rate does not include mortgage payments (debt service). Because it assumes a cash purchase, it allows you to compare the property's performance objectively, regardless of how an individual chooses to finance it. For an analysis that includes your mortgage, you would look at "Cash-on-Cash Return."
