Net Operating Income
Find net operating income, gross operating income, or operating expenses using NOI = GOI - OE. Evaluate rental property profitability before debt service.
What is Net Operating Income (NOI)?
Net Operating Income (NOI) is a fundamental calculation used to analyze the profitability of income-generating real estate investments. NOI equals all revenue from the property, minus all reasonably necessary operating expenses.
NOI is a before-tax figure, appearing on a property's income and expense statement. Importantly, it excludes principal and interest payments on loans, capital expenditures, depreciation, and amortization.
The Net Operating Income Formula
The basic formula for Net Operating Income is:
Included vs. Excluded Expenses in NOI
To compute an accurate NOI, it is crucial to distinguish between operating expenses and other property-related costs:
- Included (Operating Expenses): Property taxes, insurance, property management fees, maintenance and repairs, utilities, landscaping, and common-area maintenance (CAM) costs.
- Excluded (Non-Operating Costs): Mortgage payments (debt service), depreciation, income taxes, capital expenditures (such as replacing a roof), and leasing commissions.
Frequently Asked Questions
Why is NOI important to real estate investors?
NOI is directly used to calculate a property's value using the capitalization rate (Value = NOI / Cap Rate). It also helps lenders determine if a property produces enough income to cover its debt payments using the Debt Service Coverage Ratio (DSCR).
How does NOI differ from Cash Flow?
NOI measures property performance before financing is considered. Cash Flow is the amount of money actually left over after subtracting mortgage payments (debt service) and capital reserves from the NOI.
How can an investor increase a property's NOI?
Investors can increase NOI by raising rent prices, adding ancillary income streams (such as parking fees, laundry, or storage rentals), reducing vacancy rates, or cutting operating expenses through green energy upgrades and renegotiating vendor contracts.
