Cap rate

Capitalization rate

The capitalization rate is net operating income divided by price, expressed as a percentage. Read it as the unlevered annual yield the property throws off at the price you pay. Because it excludes financing, it is the only return metric that lets you compare a cash purchase against a leveraged one, or your market against another.

Cap rate = NOI ÷ purchase price

Worked example

$19,310 of NOI on a $265,000 purchase price is a 7.29% cap rate.

Every example in this glossary uses the same deal: a $265,000 duplex renting for $2,650 a month, bought with 25% down at 6.75% over 30 years, producing $19,310 of net operating income.

The mistake to avoid

Comparing cap rates across markets as though they were quality scores. A 9% cap in a shrinking county and a 4.5% cap in a supply-constrained metro are pricing different risk and different rent growth, not different skill.

Where this is calculated

The cap rate calculator computes this from your own numbers and shows the arithmetic expanded. Net operating income divided by price, with every expense line shown and the debt service deliberately left out.
