How is net operating income (NOI) defined?

• A. Potential gross income minus vacancy and operating expenses (before debt service).
• B. Net income after debt service.
• C. Gross rent multiplied by occupancy rate.
• D. Total cash flow after financing.

Answer: (A)

Net operating income measures what a property earns from its operations, without considering financing or taxes. It captures the property's ability to generate cash flow from its core activities. To get NOI, start with potential gross income and account for vacancies or credit losses to get to the effective gross income, then subtract operating expenses. If you simplify and assume no other income and no credits, NOI can be viewed as potential gross income minus vacancy and operating expenses, before debt service. The key point is that debt service (mortgage payments) is not included, since NOI is about operating performance. This is why the option stating potential gross income minus vacancy and operating expenses, before debt service, aligns with the standard definition. The other choices describe net income after financing, gross rent times occupancy (which ignores expenses), or cash flow after financing, none of which are NOI.
