Understanding Cap Rates in Retail Real Estate
The most quoted number in commercial real estate — what it measures, and what it leaves out.

The capitalization rate is the ratio of a property's net operating income to its price. It is simple to calculate and easy to misuse.
The formula
Cap Rate = NOI ÷ Price. Rearranged, Value = NOI ÷ Cap Rate. If a hypothetical property produces $100,000 of NOI and trades at a 6.5% cap rate, the implied value is roughly $1,538,000.
Because the cap rate sits in the denominator, small changes move value meaningfully. In the same example, a 7.0% cap rate implies about $1,429,000 — a difference of more than $100,000 from half a percentage point.
“A cap rate is a snapshot of one year's income — not a forecast.”
What a cap rate does not tell you
A cap rate is a snapshot of one year's income. It does not account for rent growth, upcoming vacancies, capital expenditures, or financing. Two properties at the same cap rate can have very different futures.
It also depends on whose NOI you are using. A seller's pro forma, a trailing twelve months, and a buyer's underwritten figure can all differ.
