Commercial Building Valuation Calculator

Calculate what a commercial building is worth based on its rental income. Value office, retail, or warehouse properties professionally.


How the Commercial Building Valuation Calculator works

Enter the building’s rental income, operating expenses, vacancy rate, and local market cap rate. Calculate the property value using the income approach.

Commercial buildings are valued by their income, not comparables like houses. Get accurate valuations for investment decisions or sales.

How it works

Tutorial

Commercial buildings are valued based on the income they generate, not by comparing to nearby sales like residential properties. Learning to calculate value from rental income helps you evaluate investment properties, negotiate purchases, or price buildings for sale.

You have two options: use the calculator above for instant valuations, or follow this guide to calculate commercial property values yourself.

The Income Valuation Method

TermWhat It Means
Net Operating Income (NOI)Rental income minus operating expenses
Cap RateExpected return rate in your local market
Property ValueNOI ÷ Cap Rate

Step-by-Step Valuation Example

Here’s how to value a commercial building from income.

Step 1: Calculate Net Operating Income

Find the property’s annual profit:

Income/Expense ItemAnnual Amount
Gross Rental Income (10 units @ $2,000/month)$240,000
Minus: Vacancy (5% typical)-$12,000
Effective Rental Income$228,000
Property Taxes-$18,000
Insurance-$6,000
Maintenance & Repairs-$15,000
Property Management (5%)-$11,400
Utilities (owner-paid)-$8,000
Net Operating Income (NOI)$169,600

Calculation:$228,000 income – $58,400 expenses =$169,600 NOI

Step 2: Find the Market Cap Rate

Research similar buildings that sold recently:

Comparable SaleSale PriceNOICap Rate
Building A$2,000,000$150,0007.5%
Building B$2,200,000$165,0007.5%
Building C$1,900,000$145,0007.6%
Market Cap Rate7.5%

Finding:Similar buildings in your area sell at7.5% cap rate

Step 3: Calculate Property Value

Divide NOI by cap rate to find value:

ComponentValue
Net Operating Income$169,600
Market Cap Rate7.5%
Property Value$169,600 ÷ 0.075 =$2,261,333

Final Answer:This building is worth approximately$2,260,000

How to Use This Valuation

At $169,600 annual profit and 7.5% market cap rate, this building is worth $2.26 million. If someone offers it for $2.5 million, you’d only earn a 6.8% return, which is below market. If they’ll sell for $2 million, you’d earn 8.5%, which is a good deal. The cap rate is like a reverse price-to-earnings ratio for real estate.
