Net Operating Income (NOI)

Annual rental income minus operating expenses, before mortgage payments.

Definition

Net Operating Income is the annual income a property generates after subtracting all operating expenses but before deducting mortgage payments and income taxes. NOI is the foundation for many real estate calculations including cap rate and property valuation. Commercial lenders rely on NOI to determine how much they will lend on a property.

Formula

NOI = Gross Rental Income − Vacancy Loss − Operating Expenses

NOI equals gross rental income minus vacancy losses minus operating expenses (excluding mortgage).

Example

A property collects $36,000 in annual rent with $1,800 in vacancy loss. Operating expenses (taxes, insurance, maintenance, management, HOA) total $9,200. NOI = $36,000 − $1,800 − $9,200 = $25,000.
