Key Concepts

What Is a Cap Rate?

Capitalization rate — universally called the 'cap rate' — is the most widely used metric in commercial real estate valuation. It expresses the relationship between a property's net operating income (NOI) and its market value. Understanding cap rates is essential for evaluating investment properties, comparing markets, and understanding how lenders underwrite commercial loans.

How to Calculate Cap Rate

Cap Rate = Net Operating Income (NOI) ÷ Property Value (or Purchase Price). Example: A property generates $120,000 in annual NOI and is priced at $1,500,000. Cap rate = $120,000 ÷ $1,500,000 = 8.0%. NOI is calculated by subtracting all operating expenses (property taxes, insurance, maintenance, management fees, utilities, reserves) from gross rental income. NOI does NOT include mortgage payments — cap rate is a pre-debt metric that allows apples-to-apples comparison regardless of financing structure.

What Cap Rate Tells You

A cap rate represents the unlevered yield an investor receives if they bought a property all-cash. Higher cap rates generally indicate higher risk or lower-demand markets. Lower cap rates indicate lower risk, higher demand, or stronger credit tenants. For example: A 4% cap rate in Manhattan reflects premium pricing for stable, high-demand assets. An 8% cap rate in a secondary market reflects higher risk and return expectations. Cap rates also move inversely with property values — as prices rise, cap rates compress; as prices fall, cap rates expand.

Cap Rates in Lender Underwriting

Commercial real estate lenders use market cap rates to derive property value independent of the purchase price. This is critical when a buyer overpays or when a seller's stated NOI is inflated. Lenders apply a market cap rate to the actual verified NOI to arrive at their own appraised value, which then becomes the basis for LTV calculations. If a lender applies a 7.0% cap rate to $100,000 NOI, the derived value is $1,428,571 — regardless of what the buyer agreed to pay.
