Plain-language meaning
In real estate, NOI estimates income from operations before mortgage payments, income taxes and capital structure. It is a key input for cap rate and property valuation calculations.
Example
A rental property with 90,000 in effective gross income and 36,000 in operating expenses has NOI of 54,000.
Limitations
NOI depends on what is included as operating income and operating expense. Debt service, depreciation, income tax, owner-specific financing and major capital expenditures are usually treated separately.
