How the Cap Rate Works
The capitalization rate or cap rate is the most widely used metric in real estate investing. It measures the expected return on a rental property based on the net operating income relative to the purchase price. Cap rate allows you to compare properties across different price points and markets on a level playing field. A 500K property with 30K NOI has a 6% cap rate. Compare cap rate to local ten year Treasury spread for rough risk premium context. Five hundred thousand price with forty five thousand NOI implies nine percent cap rate unlevered. Vacancy at eight percent on fifty thousand gross rent removes four thousand before expense deductions.
This calculator starts with gross annual rent then subtracts vacancy losses and operating expenses to arrive at Net Operating Income. NOI is divided by the purchase price to get the cap rate. A higher cap rate generally means higher return but also often indicates higher risk or a less desirable location. Compare cap rates only among similar property types in the same submarket. Five hundred thousand price with forty five thousand NOI implies nine percent cap rate unlevered. Vacancy at eight percent on fifty thousand gross rent removes four thousand before expense deductions. Cap rate compresses in hot markets when prices rise faster than NOI during bidding wars.

FAQ
What is a good cap rate?
A good cap rate depends on your market and investment goals. In major cities 4 to 6 percent is common. In secondary markets 7 to 10 percent is typical.
