The Capitalization Rate (Cap Rate) is one of the most fundamental metrics used in commercial and residential real estate investing to measure an income-producing property’s unleveraged yield and rate of return. Cap rate reflects the expected percentage return a real estate investor would earn if the property were purchased entirely in cash. Using our free Cap Rate Calculator enables real estate investors, landlords, and brokers to calculate Net Operating Income (NOI), evaluate property valuation, and compare investment opportunities across different markets.
Whether you are analyzing a multi-family apartment building, commercial office space, or single-family rental portfolio, read on to explore capitalization formulas, market cap rate benchmarks, and step-by-step calculation guides.
How Capitalization Rate (Cap Rate) Is Calculated
Cap rate calculations require determining a property’s Net Operating Income (NOI) relative to its purchase price or current market value:
1. Capitalization Rate Formula:
Cap rate is expressed as a percentage calculated by dividing annual Net Operating Income by current market value or purchase price:
Cap Rate (%) = (Net Operating Income / Property Purchase Price) × 100
2. Net Operating Income (NOI) Formula:
NOI represents all revenue generated by the property minus mandatory operating expenses (excluding mortgage debt service):
Gross Operating Income = Gross Potential Rental Income - Vacancy & Credit Losses
Net Operating Income (NOI) = Gross Operating Income - Operating Expenses
*Operating Expenses include property management, taxes, insurance, maintenance, utilities, and repairs. Debt service (mortgage principal and interest) is excluded.
3. Implied Property Valuation Formula:
To estimate property value based on target market cap rates:
Estimated Property Value = Net Operating Income / Target Cap Rate

The table below presents implied property market values across different annual Net Operating Income (NOI) tiers and market cap rates:
| Annual NOI | 4.0% Cap Rate (Primary Market) | 6.0% Cap Rate (Secondary Market) | 8.0% Cap Rate (Tertiary Market) | 10.0% Cap Rate (High Risk) |
|---|---|---|---|---|
| $50,000 / yr | $1,250,000 | $833,333 | $625,000 | $500,000 |
| $100,000 / yr | $2,500,000 | $1,666,667 | $1,250,000 | $1,000,000 |
| $250,000 / yr | $6,250,000 | $4,166,667 | $3,125,000 | $2,500,000 |
| $500,000 / yr | $12,500,000 | $8,333,333 | $6,250,000 | $5,000,000 |
Step-by-Step Calculation Example
An investor is considering purchasing a 4-unit residential building listed for $1,200,000. The building generates $120,000 gross annual rent, experiences 5% vacancy ($6,000), and incurs $42,000 in annual operating expenses.
Step 1: Compute Effective Gross Income (EGI)
Effective Gross Income = $120,000 - $6,000 (Vacancy) = $114,000.00
Step 2: Calculate Net Operating Income (NOI)
Net Operating Income (NOI) = $114,000 - $42,000 (Expenses) = $72,000.00
Step 3: Calculate Capitalization Rate
Cap Rate = ($72,000 / $1,200,000) × 100 = 6.00%
Result Summary:
The property generates an unleveraged annual capitalization rate of 6.00%.
Frequently Asked Questions (FAQ)
What is considered a “good” cap rate for real estate?
A “good” cap rate varies by market and property type. Generally, cap rates between 4% and 6% indicate low-risk, high-demand primary metro areas (Class A properties). Cap rates between 7% and 10% indicate secondary/tertiary markets with higher cash flow but elevated risk profiles.
Why are mortgage payments excluded from cap rate calculations?
Cap rates measure property asset performance independent of financing structure. Excluding debt service allows investors to compare intrinsic property yields across different financing scenarios or cash buyers.
What is the relationship between cap rate and property risk?
Cap rate is inversely related to property value and directly related to risk. Higher cap rates indicate lower purchase prices relative to income (higher perceived risk), while lower cap rates reflect lower risk and higher investor demand.
How does increasing Net Operating Income (NOI) impact property value?
Because property value equals NOI divided by cap rate, increasing NOI (by raising rents or reducing operating expenses) directly boosts commercial property value. For example, a $10,000 NOI increase at a 6% cap rate adds $166,667 in asset equity value.
