Review NOI Results
See the Net Operating Income, total income, and NOI margin percentage. NOI is a key metric for real estate investment analysis.
Formula
NOI = Total Income - Operating Expenses
Total Income = Gross Rental Income + Other Income
NOI Margin = (NOI / Total Income) × 100
Example 1: Rental Property
Gross Rental Income: $50,000/year
Other Income: $2,000/year (parking, laundry)
Operating Expenses: $20,000/year
Total Income: $52,000
NOI = $52,000 - $20,000 = $32,000
NOI Margin = ($32,000 / $52,000) × 100 = 61.54%
Example 2: Multi-Unit Property
Gross Rental Income: $120,000/year
Other Income: $5,000/year
Operating Expenses: $45,000/year
NOI = $125,000 - $45,000 = $80,000
NOI Margin = 64%
About Net Operating Income Calculator
The Net Operating Income (NOI) Calculator is an essential tool for real estate investors to evaluate the profitability and performance of rental properties. NOI is a key financial metric that represents the property's income after operating expenses but before financing costs (debt service) and income taxes. It's calculated by subtracting all operating expenses from total income, providing a clear picture of the property's operational profitability and cash flow potential.
NOI is crucial for real estate investment analysis because it's used to calculate other important metrics like cap rate (NOI / Property Value), cash-on-cash return, and debt service coverage ratio. Unlike gross income, which only shows revenue, NOI accounts for the actual costs of operating the property, giving investors a realistic view of the property's income-generating ability. A positive NOI indicates the property generates more income than it costs to operate, while a negative NOI indicates the property is losing money at the operational level.
This calculator helps investors understand the true profitability of rental properties by calculating NOI, which excludes financing costs and taxes, focusing solely on the property's operational performance. Understanding NOI is essential for comparing different investment properties, evaluating property performance, determining property value, and making informed investment decisions. The calculator also shows NOI margin, which indicates what percentage of income remains after operating expenses, providing insight into the property's efficiency and profitability.

Understanding Net Operating Income
Net Operating Income (NOI) is the income a property generates after subtracting all operating expenses but before financing costs and taxes. Operating expenses include property management, maintenance and repairs, property insurance, property taxes, utilities (if paid by landlord), advertising, legal fees, and other costs necessary to operate the property. NOI excludes mortgage payments, interest, depreciation, and income taxes, focusing solely on the property's operational performance.
NOI is a critical metric because it represents the property's ability to generate cash flow from operations. It's used to calculate cap rate (NOI / Property Value), which helps investors compare properties and determine value. A higher NOI generally indicates a more profitable property, but it's important to consider NOI in relation to the property value and purchase price. NOI margin (NOI / Total Income) shows what percentage of income remains after expenses, with higher margins indicating more efficient operations.
Real-World Applications
Property Evaluation: An investor evaluates a rental property with $60,000 annual income and $25,000 operating expenses. The NOI is $35,000. If the property costs $500,000, the cap rate is 7% ($35,000 / $500,000), helping them evaluate the investment.
Property Comparison: Comparing two properties: Property A has $40,000 NOI on a $600,000 value (6.67% cap rate), while Property B has $35,000 NOI on a $500,000 value (7% cap rate). Property B has a better cap rate despite lower NOI.
Performance Analysis: A property owner tracks NOI over time. Year 1 NOI was $30,000, but after increasing rents and reducing expenses, Year 2 NOI is $38,000, showing improved property performance.
Important Considerations
- NOI excludes financing costs (mortgage payments) and income taxes
- Operating expenses should include all costs necessary to operate the property
- NOI is used to calculate cap rate, a key metric for property valuation
- Compare NOI across similar properties in similar markets for meaningful analysis
- NOI can be negative if operating expenses exceed income
- Consider vacancy rates and collection losses when calculating gross rental income
Frequently Asked Questions
What is Net Operating Income (NOI)?
Net Operating Income (NOI) is the income a property generates after subtracting all operating expenses but before financing costs (mortgage payments) and income taxes. It represents the property's operational profitability and is a key metric for real estate investment analysis.
What expenses are included in NOI?
Operating expenses included in NOI are: property management, maintenance and repairs, property insurance, property taxes, utilities (if paid by landlord), advertising, legal fees, and other costs necessary to operate the property. NOI excludes mortgage payments, interest, depreciation, and income taxes.
How is NOI used in real estate investing?
NOI is used to calculate cap rate (NOI / Property Value), which helps investors compare properties and determine value. It's also used to calculate cash-on-cash return, debt service coverage ratio, and other investment metrics. NOI represents the property's ability to generate cash flow from operations.
What is a good NOI margin?
A good NOI margin varies by property type and market, but generally, margins of 50-70% are considered healthy for rental properties. Higher margins indicate more efficient operations and better profitability. Compare margins to similar properties in your market for context.
Can NOI be negative?
Yes, NOI can be negative if operating expenses exceed total income. A negative NOI indicates the property is losing money at the operational level, which is a red flag for investors. However, some investors may accept negative NOI temporarily if they expect property improvements or market changes to improve performance.
How does NOI relate to cap rate?
Cap rate is calculated by dividing NOI by property value (Cap Rate = NOI / Property Value). NOI is the numerator in the cap rate formula, so higher NOI (relative to property value) results in higher cap rates, which generally indicate better investment returns. Cap rate helps investors compare properties and determine value.
