NOI stands for Net Operating Income and is a critical metric for real estate investors. It helps determine whether a property is profitable, but its value goes beyond just assessing cash flow. Understanding NOI is key to making smarter investment decisions and growing a successful real estate portfolio.
In simple terms, NOI provides insight into a property’s financial performance by comparing income with operating expenses. For investors, this number is essential for setting rental rates, evaluating investment opportunities, and forecasting long-term profitability.
Today, we’ll explain how to calculate NOI, why it’s important, and how it can help you make more informed decisions in your real estate investments.

What is Net Operating Income (NOI)?
Net Operating Income (NOI) is a key metric that shows how much money a rental property makes after covering all operating expenses. It includes rent and other income but subtracts costs like maintenance, management fees, and utilities. However, it does not include mortgage payments or taxes.
For real estate investors, NOI is important because it helps measure a property’s profitability and overall financial health. It is also used to compare different properties and determine market value. A strong NOI means a property is performing well, while a low NOI could signal potential issues.
Investors also use NOI to calculate the capitalization rate (cap rate), which helps determine whether a property is a good investment. By understanding NOI, investors can make smarter decisions and maximize their returns.
How to Calculate Net Operating Income (Formula & Examples)
To calculate NOI, simply subtract a property’s total operating expenses from its gross income.
Net Operating Income (NOI) Formula:
Key Components of NOI:
- Gross Rental Income: This includes all rental income and other property-related revenue.
Examples: Rent payments, late fees, parking fees, laundry income, etc. - Operating Expenses: These are the necessary costs to run and maintain the property, such as:
- Maintenance and repairs
- Property taxes
- Insurance
- Utilities (if paid by the landlord)
- Property management fees
NOI Example:
Let’s say your rental property generates $40,000 in annual rental income. The total operating expenses (maintenance, taxes, and management fees) amount to $15,000 each year. Using the formula:
NOI = $40,000 – $15,000 = $25,000
This means your property’s Net Operating Income (NOI) is $25,000. This figure is crucial for assessing the property’s profitability and making informed investment decisions.
Why NOI Matters for Real Estate Investors
NOI is one of the most critical metrics for assessing a property’s performance. Here’s why it matters:
Helps Determine a Property’s Profitability:
NOI provides a clear snapshot of how much income a property generates after covering operating expenses. Since it excludes mortgage payments and taxes, it offers an unbiased view of a property’s actual earning potential. According to a study by San Diego State University, properties with stable NOI were better positioned to withstand market fluctuations, especially during economic downturns.
Essential for Comparing Investment Properties:
Because NOI is a standardized measure, investors can easily compare different properties. A higher NOI often signals a stronger investment, assuming other factors like purchase price are similar.
Key for Property Valuation and Underwriting:
Investors and lenders often rely on NOI when determining the value of a property. By applying the cap rate (NOI divided by the property’s value), you can estimate a property’s market value based on its income potential. This makes NOI a vital metric for underwriting and property valuation.
In short, NOI helps investors make better decisions by revealing how much money a property will generate, minus the essential operational costs.

Common Mistakes When Calculating NOI in Real Estate
Even experienced investors can make mistakes when calculating NOI. Here are some of the most common errors to avoid:
1. Misclassifying Expenses:
Not all expenses should be included in NOI calculations. For example, debt service payments (mortgage) and capital expenditures (major repairs or renovations) should not be counted as operating expenses. Mistaking these can inflate your NOI, leading to inaccurate property evaluations.
2. Omitting Non-Cash Expenses:
Some expenses, like depreciation, aren’t directly paid out in cash but should still be accounted for in your operating costs. Ignoring them can distort your NOI and give you an unrealistic view of your property’s profitability.
3. Forgetting to Include All Revenue Sources:
Make sure to include all sources of income, such as late fees, parking, laundry, and storage fees. Overlooking these can lead to an understated gross income, which directly affects your NOI.
Avoiding these common mistakes is essential to getting an accurate measure of your property’s profitability, which will, in turn, help you make smarter investment decisions.
How to Improve NOI for Your Property
Increasing your property’s NOI is a great way to maximize the value of your investment. Here are some strategies you can implement to boost NOI:
1. Increase Rent (Carefully):
Raising rent is one of the most effective ways to boost NOI, but it must be done carefully. Research market trends to ensure your rental rates remain competitive while maximizing profitability. Communicate changes transparently with tenants to maintain positive relationships.
2. Reduce Operating Costs:
Lowering expenses can significantly increase NOI. For example:
- Negotiate better rates with vendors or service providers.
- Implement energy-efficient solutions to reduce utility costs.
- Streamline property management operations to reduce overhead.
3. Add Revenue Streams:
If possible, explore additional income sources:
- Charging for amenities like parking, laundry, or storage.
- Adding value through services such as cleaning or landscaping.
By improving both income and controlling expenses, you can effectively increase your property’s NOI, enhancing both its profitability and long-term investment potential.
