Capitalization Rate

Definition

The capitalization rate (cap rate) is the ratio of a property's net operating income to its sale price, expressed as a percentage. It is used to estimate value and compare profitability of investment properties. Cap Rate = NOI / Value.

Example

An office building generates $80,000 in annual NOI and sold for $1,000,000. Cap rate = $80,000 / $1,000,000 = 8%. If a similar building generates $95,000 in NOI and the market cap rate is 8%, the value = $95,000 / 0.08 = $1,187,500.

Exam Tip

Memorize the IRV formula: I (Income/NOI) = R (Rate/Cap Rate) x V (Value). You can solve for any variable. Remember the inverse relationship: as the cap rate goes down, value goes up. Do not confuse cap rate with interest rate or return on equity.
