How to Calculate Net Operating Income

Net Operating Income Formula

Net Operating Income (NOI) is a crucial component in real estate investing. It gives you a quick and easy snapshot of annual cash flow and is also the net income of a property before direct expenses.

If you’re looking to buy or sell a house, to rent or manage a property, NOI is an indispensable metric. It allows you to quickly measure your return in real estate investments.

Calculating the NOI for a real estate investment property is incredibly simple. You start by adding up the home’s gross rent received, for example one million dollars. Then you subtract the expenses associated with running the property – utility bills, insurance, repairs, vacancies, and vacancies. Finally, you net the result to arrive at the net income of your property, for example, 720 thousand dollars.

If you’re looking to buy a property, calculate the NOI in order to determine the property’s price-to-NOI ratio. The greater the ratio, the better the property is priced.

If you’re looking to sell your property, you can use the NOI to understand what your property is worth. For example, if you have a property with a 200 thousand dollar NOI, you can determine that it is worth 70 thousand dollars per year in cash flow.

When to Use Net Operating Income

There are many ways to measure a real estate investment, but you can’t beat the (NOI) Net Operating Income metric for taking an aggregate look at the performance across your entire portfolio.

NOI gives you a net profit between the expenses and income realized from operations of a property. It is the Net Operating Income of a specific real estate property that is associated with the same property.

You can use it on an actual property as well as on an entire portfolio. But NOIs are most commonly used to monitor portfolio performance on a much larger scale.

Property Management Fee: The fee charged to administer your investment portfolio and collect rent.

Repair, Maintenance, and Insurance Expenses: Work that is done on the property to keep it in good shape.

Calculations That Involve NOI

In the real estate business, a general rule that every investor can benefit from is that the more money you make, the more you should reduce your expenses.

And this is no different for No Operating Income (NOI) or Net Operating Income (NOOI). While Real Estate investors often hear of this number as a goal, it is an important number to keep track of. NOI is measured as the cash flow of the income a property generates over its Net Operating Assets (NOAs).

The NOI and Net Operating Assets (NOAs) are both important numbers any investor should track. So let’s take a look at the formulas and our process for calculating NOI.

Examples of When Net Operating Income Is Used in Real Estate

New York – Cash flows from real estate investments are measured annually by the net operating income (NOI) formula. This formula measures the total annual income from the property including interest earned, expenses paid, and other payments and income generated. NOI is calculated after adjusting the nominal operating income for taxes paid.

New York – NOI is calculated by dividing the net income from a property by the average invested capital. NOI should be broken down into two main categories: operating income and amortization and depreciation.

The operating income number should be based on the actual revenue revenue generated by the property. This number is then further broken down by tenant rents, management fees, and other operating expenses.

The amortization and depreciation number is used to calculate the total amortization and depreciation of an investment property like a building, land, or a land development. It also includes the cost of repairs and improvements of a property.

Pros and Cons of Using Net Operating Income

NOI is often one of the largest expenses for real estate investors. Most investors need a full year’s rent in the bank before reaching this point, so they determine their NOI based on covering their initial cost and the growing principle on a monthly basis.

Regardless, calculating NOI for your business is essential. You have to know at least your total expenses, so you can determine the amount of money in your checking account after a year’s worth of business. And you have to make sure it guarantees your goal of covering your yearly expenses in the bank.

Cons of Using NOI

NOI is the calculation you use to calculate what your real estate investment properties are earning you. In real estate investing, you don’t see your net income on paper (since you’re running a business), but you can calculate your NOI.

NOI is important because it is used to determine how much and when you are able to pay your mortgage or to add to your rental income. For instance, you want to buy a property in order to turn a net profit. But let’s say you don’t buy the property because you can’t show up the current mortgage payments on one income.

This could mean that you’ll have to rent out the property and use your income to pay the mortgage instead, thereby reducing your cash flow.

To get a good estimate of how much money you’re able to make off of a property, you can calculate NOI.

But this is easier said than done. The formula is complicated and you’ll have to spend a lot of time calculating figures and ratios.

Alternatives to NOI Formula

Fortunately, there are a few alternatives to the confusing and time-consuming NOI formula.

How to Improve Net Operating Income


Net Operating Income (NOI) or Net Income is a critical metric or source of data for building your Net Worth, determining if your investments are generating a profit.

The number is simple to calculate. You take your Cash Flow from your Cash Floors(eg. your Equity, Investments etc.) and deduct operating expenses (eg. Mortgage, Tax, Insurance etc.)

To get the NOI you take your ASSETS and subtract your LIABILITIES to get the Net Operating Income.

Then to establish the Net Operating Income for a property, you take your NOI and divide it by your Total Cost of Ownership to get the Net Operating Income for that property.

Cash Floors can be less net operating income if you don’t get your Cash Floors and Credit Card payments down to a very low percentage of your Debt (eg. 3%).

Improve Rental Income

It’s easy to focus on your expenses and forget to think about your income. You’re lucky if you get a nice sunset view or a sunny window, and you think that’s enough. Unfortunately, that’s not true, and you’ll be surprised to hear just how much you need to think about your income.

Secondly, the higher net income will make you more likely to get a loan for your property.

Net Operating Income Frequently Asked Questions (FAQs)

Operating income and net operating income are numbers that are often tossed around in the real estate investment business, but the institutions that use the numbers need to have a working knowledge of how to use and interpret NOI. Without a good grasp of how NOI is calculated, it is difficult to make sound, confident real estate investing decisions.

To help you understand how NOI is calculated and what the numbers are used for, we talked to some of the experts in the real estate investing business, like consultant and investor Steve Clayton and realtor and broker Lori Burch of Berkshire Hathaway HomeServices California Properties.

How is NOI calculated?

NOI is calculated by taking NOAI and adding net operating income (NOI), which is a percentage of profits from the real estate business. Property managers and maintenance managers as well as operations managers in the real estate business can calculate NOI.

NOI is calculated by taking NOAI and adding net operating income (NOI), which is a percentage of profits from the business. Property managers and maintenance managers as well as operations managers in real estate business can calculate NOI.

To calculate NOI, you need to break down the entire amount of revenue the business brought in, which is equal to keeping track of all the expenses of running the property. the income from the rental is subtracted from the total expenses.

Is My Mortgage Payment Part of NOI?

NOI formula focuses on a net operating income (NOI) , which includes fixed operating expenses, or actual costs of doing business a property. Actual operating expenses are fixed costs that are not related to a property’s occupancy or rent. Mostly, rental expenses (rent or mortgage payments) are included in income statement, but these expenses don’t relate to the day to day operations of a property. For example, rent expenses include mortgage payments, utility bills, repairs and maintenance and property taxes for a property.

For calculating NOI, mortgage expenses include down payments, monthly payments, interest payments, escrow fees and real estate taxes. These expenses secure the property’s revenue stream while it is owned by the investor. Overall, the NOI formula considers expenses that are directly related to a rental property…not related to tenant occupancy.

Are Property Management Fees Part of the Net Operating Income Formula?

The Net Operating Income for Real Estate Investors (NOI) formula requires owners to subtract from the monthly gross rent the amount of investment cost incurred on the property. This cost can be incurred in a variety of ways, including property management, repairs and maintenance, and taxes.

Property management accounts for roughly 10 percent of NOI. This number is typically higher for investment properties with a kitchen, laundry, and other utilities needed by the tenants. On the other hand, independent owners can manage the property themselves without incurring any cost.

It’s important to note that this 10 percent figure set aside for management fees, not only covers the actual costs of operating the property, but also the costs associated with finding a tenant. Without this budget, owners may only pay attention to the expense of the property itself and forget about getting and keeping tenants. Don’t forget to keep an eye on vacancy rates, too, as a low vacancy rate is an indication that the property is getting a lot more for its money than an owner may realize.

How Do I Calculate NOI?

Net Operating Income (NOI) is a fundamental metric used to determine the amount of money a property generates on a monthly basis. In short, it’s the “gross” income minus the expenses of a real estate property.

A NOI calculation can be done for all property types. For example, if you want to buy a house in Virginia Beach, you will be able to figure your NOI based on VA Beach house prices.

When factoring in the gross income of the property, NOI is a more accurate way of determining the amount of cash flow a property generates.

Here’s how you can derive your NOI (assuming 100 units exist at your property in a month):

  • NOI=
  • Gross Income (x) – Operating Expenses (y)
  • 100
  • Net Operating Income ((x – y) / 100)

If you’re considering purchasing a rental property, it’s important to know the NOI of the property you’re planning to purchase. If the NOI is above your budget or if you’re planning to finance your purchase, you must ensure your private lenders will agree to the loan…ed based on your NOI.

It could also help you decide whether or not your property is worth your investment.

Is Net Operating Income Only Used in Real Estate?

Not really. Net Operating Income is the amount of operating income available to a business after it has paid all of its operating expenses. Depending on the business, this amount is known as Net Income, Net Income per Share, Net Retained Earnings etc.

Net Operating Income is used in real estate, for instance, when analyzing a property’s or shopping center’s profitability. NOI is also used as a measurement in financial analysis and is used for buying and selling real estate. Further, Government regulations require NOI calculations, usually as part of an Economic Development Investment Program (EDIP) to determine a tax incentive’s or grant’s eligibility.

The NOI formula is actually quite simple, and it relates back to the total revenue of a business minus its total operating expenses:

NOI = Revenue – Operating Expenses

However, the formula only appears simple but it’s actually quite complex. There are numerous variables involved, such as Fixed and Variable expenses, and some of them can be manipulated with changes to accounting practices and business strategies.
