What is Net Operating Income (NOI)?
Net Operating Income (NOI) is a key financial metric used to measure a property's profitability by subtracting operating expenses from total revenue, excluding financing costs and taxes. It provides a clear picture of operational income, distinct from net income and other profit measures.
NOI is widely applied in real estate to assess property performance and value, enabling investors to compare properties without influence from varying financing structures.
Key Characteristics
Understanding NOI requires recognizing its core elements and what it excludes. Key characteristics include:
- Revenue Sources: Includes rental income plus ancillary income like parking or laundry fees, reflecting all operational revenue streams.
- Operating Expenses: Covers property management, maintenance, utilities, insurance, and taxes, but excludes mortgage interest and capital expenditures.
- Exclusions: NOI does not account for depreciation, amortization, income taxes, or financing costs, differentiating it from operating income.
- Valuation Use: Integral in calculating property value via capitalization rates, where property value approximates NOI divided by the cap rate.
How It Works
To calculate NOI, start with the total potential income from a property, subtract vacancy losses to get effective gross income, then deduct operating expenses. This process isolates income purely from operations, excluding financial and tax impacts.
NOI serves as a standardized metric, allowing you to evaluate properties on their operational cash flow potential. It is also a critical input for lenders assessing loan risk through metrics like the debt coverage ratio, linking NOI to loan-to-value considerations.
Examples and Use Cases
NOI is applied across various real estate investments and industries to gauge performance and inform decisions:
- Retail Properties: Companies like FRT use NOI to measure income after operating costs, aiding investors in understanding cash flow consistency.
- Commercial Real Estate: Real estate investment trusts such as NNN report NOI to highlight their property portfolio's operating efficiency.
- Airlines and Other Sectors: While primarily a real estate metric, understanding NOI relates to broader financial analysis, complementing metrics like rate of return in investment evaluation.
Important Considerations
When using NOI, remember it assumes an all-cash purchase and excludes debt service, so it should be paired with other metrics for a full financial assessment. Accuracy depends on current data and proper normalization of expenses.
Be cautious not to confuse NOI with operating income or include non-operating costs, as this can distort property valuation and investment decisions.
Final Words
Net Operating Income (NOI) offers a clear snapshot of a property's operational profitability by isolating income and expenses tied directly to its management. Use this metric to compare investment opportunities and refine your valuation; running NOI calculations across multiple properties will sharpen your investment decisions.
Frequently Asked Questions
Net Operating Income (NOI) is a measure of a property's profitability calculated by subtracting operating expenses from total property revenue, excluding financing costs, capital expenditures, depreciation, amortization, and income taxes.
To calculate NOI, start with total revenue from rent and ancillary income, subtract vacancy and credit losses to get effective gross income, then subtract operating expenses such as maintenance, utilities, and property management fees.
NOI includes rental income from tenants plus ancillary income sources like parking fees, laundry services, storage fees, pet fees, utilities, vending machines, and late fees.

NOI helps investors assess a property's cash flow potential and compare profitability across different properties, making it useful for valuation, investment analysis, and loan underwriting.
Property value is often estimated by dividing NOI by the capitalization rate (cap rate), so a higher NOI generally increases the property's market value.
Yes, because NOI standardizes operational income by excluding financing and tax factors, it allows investors to fairly compare the operational profitability of properties across various markets.
Operating expenses include property management fees, maintenance and repairs, utilities, insurance, property taxes, and advertising or leasing commissions necessary for property operation.
