Understanding NOI for Property Lenders and Investors

Property evaluation is a science of its own, where it’s crucial to know all parts of your equation, especially for investment properties and investors picking the highest-profitable options on the market. See, you may already know what net income is — pure, total profits after all deductions, expenses, and taxes. But do you know your net operating income, which is a completely different thing? 

What is Net Operating Income or NOI?

Net operating income is a metric that helps understand just how much profits are made by your investment property with its rental, amenities, and additional services. To be more specific, NOI is the investment property’s income after all operating expenses but before deducting any financing costs, income taxes, depreciation, and major capital expenditures. 

In the industry, this is called operating income

The operating income is what you earn monthly from your residents — the rent you collect, the fare for parking you make, down to the change accumulated in your laundry machines. We’re talking about recurring operations in commercial real estate, which, in truth, keep the property functioning and in demand (the exact operations are listed below).

But more than that, NOI reflects the operating performance of your property, allowing you to see whether your real estate financing is balanced enough. For instance, you may learn that certain operations are eating up expenses instead of contributing to profits. You can thus adjust your investment focus and choose new directions for financing

How to Calculate NOI?

To calculate your net operating income, you need to know two things — how much your property operations generated in total and what expenses it took to keep those operations running. 

The NOI formula goes as follows:

NOI = Gross operating income – Operating expenses

Where:

Gross operating income includes:

  • Rental income
  • Parking fees
  • Laundry income
  • Storage fees
  • Other recurring property-related income

Operating expenses include:

  • Property taxes
  • Property insurance
  • Property management fees
  • Routine maintenance and repairs
  • Utilities (if paid by the owner)
  • Security services
  • Landscaping and janitorial services
  • Marketing and leasing expenses
  • Administrative costs related to property operations

NB: NOI does not include:

  • Mortgage payments (both principal and interest)
  • Income taxes
  • Depreciation and amortization
  • Capital expenditures (such as replacing a roof or HVAC system)

An Explicit Example

Suppose you own an apartment building that normally generates:

  • Annual rental income of $500,000
  • Parking and laundry income of $20,000
  • Operating expenses of $180,000

In this case, the calculation would be:

NOI = ($500,000 + $20,000) – $180,000 = $340,000

At the operating bottom line, the property’s annual net operating income is at $340,000. This should give you a pretty clear picture of what net operating income is and how it’s calculated.

How Does NOI Compare Against Other Income Metrics?

Net Operating Income (NOI) is just one of several metrics used to evaluate the financial performance of an income-producing property. While you’re in no way limited to calculating any profit-making aspect of your property, NOI stands out — it shows you just how profitable your property’s day-to-day operating activities are. 

Other metrics reflect revenue, financing, or the owner’s actual earnings. You can really analyze things thoroughly by combining a bunch of useful metrics, but first, learn to distinguish them:

MetricWhat it measuresIncludes financing costs?Best used for
Gross Rental Income (GRI)Total rent collected before any deductionsNoMeasuring a property’s revenue potential
Gross Operating Income (GOI)Rental and other operating income after vacancy and credit lossesNoAssessing effective income generation
Net Operating Income (NOI)Operating income after operating expensesNoComparing properties and estimating market value
Cash FlowMoney remaining after all expenses, including loan paymentsYesEvaluating the owner’s actual investment returns
Net IncomeFinal accounting profit after all expenses, taxes, interest, and depreciationYesFinancial reporting and tax purposes
EBITDABusiness operating earnings before interest, taxes, depreciation, and amortizationNoComparing the operational performance of companies rather than individual properties

Let’s break it down:

NOI vs. GRI

Gross Rental Income measures the total rent a property could generate before accounting for any vacancies or expenses. It provides insight into revenue potential but says little about profitability. 

NOI helps analyze the profitability more in-depth as it deducts ongoing operating costs.

NOI vs. GOI

Gross Operating Income comes before NOI — it shows the income from vacancies, bad debt, and additional revenue streams such as parking or laundry fees. 

But the NOI subtracts operating expenses from the GOI figure and shows us if the cost of property management is justified. 

NOI vs. Cash Flow

Cash Flow shows how much money the owner actually keeps after paying mortgage principal and interest, taxes, and other financing obligations.

In turn, NOI measures the property's operating performance before any debt payments even take place.

NOI vs. Net Income

Net Income is the bottom line reported on financial statements. It includes articles of expenses unrelated to operating activities, such as:

  • Interest expenses
  • Income taxes
  • Depreciation and amortization
  • Other non-operating gains and losses

NOI vs. EBITDA

EBITDA means Earnings Before Interest, Taxes, Depreciation, and Amortization. Confusingly, NOI and EBITDA are conceptually similar — they both measure operating performance of an asset before financing and taxes. 

However, NOI is a metric used for income-producing real estate only, whereas EBITDA is a broad reflection of an entire business’s operating performance, across all industries it works in. Thus, EBITDA doesn’t count in property depreciation and amortization. 

Who Can Use NOI and for What

NOI is an irreplaceable metric for property owners, lenders, and investors alike. All property-related parties, as well as administrators, managers, and service personnel, can use the NOI to:

  • Compare the total profitability of different investment properties;
  • Estimate a property’s market value using the capitalization (cap) rate;
  • Evaluate whether a property generates enough income to support debt payments;
  • Find ways to increase total value by boosting revenue or cutting operating costs.
