What Is a Cap Rate?
A capitalization rate, commonly called a "cap rate," is a fundamental metric in commercial real estate valuation and investment analysis. It represents the unlevered return on a property—the annual return you would earn if you purchased the property entirely with cash, with no debt financing. The cap rate is expressed as a percentage and is calculated by dividing the property's net operating income by its market value or purchase price.
Cap rates vary across markets, property types, and economic cycles. In strong markets with high investor demand, cap rates compress (shrink), meaning investors are willing to accept lower returns in exchange for stability or growth potential. Conversely, in weak markets or for riskier assets, cap rates expand (widen), reflecting higher required returns to compensate for perceived risk.
Unlike cash-on-cash return (which factors in leverage and year-one cash distributions), the cap rate isolates the income-generation capacity of the property itself. This makes it a universal benchmark for comparing properties across different financing scenarios and across different investor portfolios.
