Net Operating Income (NOI): What It Is + Why It Matters

What is NOI, and why does it matter to you as a real estate investor or landlord? Net operating income, or NOI, is a key profitability metric used in the real estate sector. Net Operating Income (NOI) is a critical metric for property managers as it determines a property's value, gauges its profitability, and influences loan acquisition prospects. It totals your remaining income after paying all operating expenses, so a higher NOI implies a more profitable property, potentially increasing its market value and attractiveness to lenders and investors.

Furthermore, NOI guides managers in future budgeting and strategic planning, potentially triggering adjustments in rent or operating costs. Hence, property managers constantly strive to enhance NOI through methods such as reducing vacancies, improving tenant retention, or optimizing expenses.

In this article, we will guide you through everything you need to know about NOI. We'll cover the definition, the NOI formula to calculate it, and the elements to include or exclude in your calculations.

What Is NOI?

NOI, or net operating income, is the income generated from a property after subtracting operating expenses but before taking mortgage payments, taxes, and depreciation into account.

Understanding NOI is crucial for both property owners and potential investors as it provides a clear, unobstructed view of a property's profitability. It gives you the ability to evaluate the income potential of a property without the influence of various financial factors, such as loan interest and income taxes.

NOI Formula

The net operating income formula, or net income equation, is relatively straightforward:

Net Operating Income = Gross Operating Income − Operating Expenses

To calculate net operating income, this formula succinctly encapsulates the primary elements of the equation.

How to Calculate Net Operating Income

Wondering about the specifics of how to calculate NOI beyond using the net operating income calculation? The different components of the NOI formula include gross operating income, potential rental income, vacancy rates, additional income, and operating expenses. But what do these terms mean?

What Is Gross Operating Income?

Gross operating income refers to the total income earned from a property before subtracting any operating expenses. This income often includes rent payments, any additional fees collected from tenants, and other income generated by the property. It is a key component of the NOI formula, essentially representing the total potential earnings a property could generate before costs.

What Is Potential Rental Income?

Potential rental income represents the maximum amount of income a property can earn if it were fully occupied and all rents were collected. This calculation provides a theoretical peak for income generation and helps to set a benchmark against which actual income can be measured. Understanding the potential rental income of a property is key to assessing its investment potential.

What Are Vacancy Rates?

Vacancy rates measure the percentage of a property's units that are unoccupied at a given time. These rates directly affect the potential rental income and, therefore, the NOI of the property. High vacancy rates can drastically reduce a property's NOI, making it a less attractive investment.

What Are Operating Expenses?

Operating expenses include all costs associated with running and maintaining the property. These can include property management fees, maintenance and repair costs, utility bills, insurance, and property taxes. Accurately calculating these expenses is essential to derive a precise NOI, offering a realistic view of a property's profitability.

How to Take Additional Income Into Account

Apart from rent, properties may generate additional income from sources like parking fees, laundry machines, or other amenities. Factor in this often-overlooked additional income into your gross operating income when calculating NOI. It can sometimes significantly impact the profitability of a property.

What NOT to Include in NOI

If you’re wondering how to find operating income, it's crucial to understand what not to include in the operating income equation. Certain costs are not considered operating expenses and should not be subtracted from your gross operating income when calculating NOI.

Income Taxes

Income taxes are not considered an operating expense and should not be included in NOI calculations. Taxes are usually dependent on an individual's or entity's financial situation and are not directly related to the property's operation. While important for broader financial planning, they do not factor into the calculation of NOI.

Debt Service

Debt service, or mortgage payments, are also not included in NOI. These are financing costs, not operating expenses, and they can vary significantly depending on the specifics of a loan agreement. While debt service is important when considering the total cost of owning a property, it is not part of the NOI calculation.

Capital Expenditures

Capital expenditures are the costs associated with major repairs or improvements to the property. These costs are not counted as operating expenses since they are not regular, recurring costs associated with the property's operation. Examples could include the cost of replacing a roof or renovating a unit.

Depreciation

Depreciation is a non-cash expense that accounts for the gradual wear and tear of the property over time. While it's an essential concept for tax purposes and the broader financial understanding of an investment, it's not factored into NOI calculations. The NOI focuses only on the actual income and expenses related to the property's operation.

Final Thoughts

The concept of net operating income (NOI) is a useful tool in property management. By fully understanding and leveraging NOI, property managers are empowered to make informed, data-driven decisions about the properties they oversee. NOI can serve as a yardstick for comparing the performance of different properties, aid in developing strategies for revenue enhancement and cost containment, and ultimately contribute to more efficient and profitable property year-round.
