What is the capitalization rate (cap rate) formula, and how is it used in real estate investment analysis?
Cap Rate = Net Operating Income (NOI) divided by Property Value. If a property generates $40,000 NOI and is valued at $500,000, the cap rate is 8%. Cap rate indicates the annual return on investment and is used to compare properties and estimate values.

Real Estate Math on the Real Estate Exam
Cap rate is fundamental to investment property valuation and analysis. Investors use it to compare properties and make investment decisions. Cap rate appears on exams because it tests higher-level math skills and practical investment knowledge. Understanding how to calculate NOI and apply cap rates is essential.

What It Means
The capitalization rate (cap rate) is a metric that expresses the relationship between a property's annual net operating income and its value. It represents the percentage return an investor would earn from the property based on current income and price. The cap rate formula is: Cap Rate = NOI / Property Value. For example, if a rental property generates $50,000 in annual net operating income and is valued (or purchased for) $625,000, the cap rate is $50,000 / $625,000 = 8%.
Net Operating Income (NOI) is calculated as Gross Rental Income minus Operating Expenses. Gross Rental Income includes all rent collected from tenants. Operating Expenses include property taxes, insurance, maintenance and repairs, property management fees, utilities (if paid by owner), vacancy allowance, and other costs of operating the property. Operating expenses do not include debt service (mortgage payments) or capital improvements. For example: Gross Rental Income of $60,000 minus Operating Expenses of $10,000 equals NOI of $50,000.
Cap rate is useful for several purposes. First, it allows investors to compare properties on a standardized basis. A property with an 8% cap rate is directly comparable to another property with a 10% cap rate in terms of return on investment, regardless of the properties' prices. Second, cap rate can be used to estimate a property's value if you know the NOI and the appropriate cap rate for the market: Property Value = NOI / Cap Rate. If NOI is $40,000 and the market cap rate for similar properties is 8%, the property value is $40,000 / 0.08 = $500,000. Third, cap rate helps investors assess whether a property is a good investment given current market conditions and interest rates.
Cap rates vary by market, property type, and location. In strong markets, cap rates may be 4-6% (lower rate, higher price). In softer markets or for riskier properties, cap rates may be 8-12% or higher. Cap rates have an inverse relationship with property prices; as prices rise, cap rates fall (for the same NOI), and as prices fall, cap rates rise. Cap rate is distinct from cash-on-cash return, which measures the return on the actual cash invested (down payment), and from Internal Rate of Return (IRR), which accounts for appreciation and tax benefits over time.
