Cap Rate Calculator
Calculate the capitalization rate (cap rate) using Net Operating Income (NOI) and property value. Ideal for real estate investors comparing rental properties and estimating returns.
NOI = Rental Income − Operating Expenses (excludes loan EMIs & taxes).

Cap Rate Calculator – Capitalization Rate Explained for Real Estate Investors
The capitalization rate, commonly referred to as the cap rate, is one of the most widely used metrics in real estate investing. It helps investors quickly evaluate the income potential of a property relative to its market value. Whether you are analyzing a residential rental, a multi-family apartment building, or a commercial property such as an office, retail unit, or warehouse, cap rate provides a standardized way to compare opportunities across different markets and property types.
This Cap Rate Calculator allows you to calculate capitalization rate using annual Net Operating Income (NOI) and property value. By isolating operating performance from financing and tax considerations, cap rate focuses purely on how efficiently a property generates income from its operations.
What Is Capitalization Rate (Cap Rate)?
Capitalization rate is a percentage that expresses the relationship between a property’s annual net operating income and its market value. It represents the theoretical annual return an investor would earn if the property were purchased with cash and operated at current income and expense levels.
Because cap rate excludes financing, income taxes, and appreciation, it is primarily used as a comparison and valuation tool rather than a complete measure of investment return. Investors often use cap rate during initial screening before conducting deeper financial analysis.
Cap Rate Formula
Cap Rate (%) = (Net Operating Income ÷ Property Value) × 100
Where:
- Net Operating Income (NOI): Annual income after operating expenses, excluding loan payments and taxes
- Property Value: Purchase price or current market value of the property
Example: Cap Rate Calculation
Example Property:
Annual NOI: 480,000
Property Value: 6,000,000
Cap Rate = (480,000 ÷ 6,000,000) × 100 = 8%
This means the property generates an annual return of 8% based purely on operating income relative to its value, before considering leverage, appreciation, or tax benefits.
Why Cap Rate Matters
Cap rate is widely used by investors, lenders, and appraisers because it allows properties to be compared objectively. Two properties in different cities or countries can be evaluated on the same scale using cap rate, even if financing terms or ownership structures differ.
In commercial real estate, cap rate is also a key valuation tool. Properties are often priced based on prevailing market cap rates. A lower cap rate typically reflects lower perceived risk, stronger tenant demand, or premium locations, while higher cap rates may indicate higher risk or weaker market conditions.
Typical Cap Rate Ranges
- Prime residential or commercial markets: 3% – 5%
- Stable rental markets: 5% – 7%
- Higher-risk or emerging markets: 7% – 12%+
These ranges vary by location, asset type, interest rate environment, and economic conditions. Cap rates are not fixed benchmarks and should always be interpreted in context.
What Cap Rate Does Not Show
While cap rate is useful, it has important limitations. It does not account for financing structure, mortgage payments, tax benefits, appreciation potential, or future changes in income and expenses. A property with a high cap rate may still produce poor cash flow if debt payments are excessive.
Because of these limitations, experienced investors use cap rate as an initial screening metric rather than a final decision tool.
Cap Rate vs Other Investment Metrics
- Cash Flow: Measures money left after all expenses and loan payments
- Cash-on-Cash Return: Evaluates return on invested equity
- IRR: Measures total return over time including appreciation
- DSCR: Assesses ability to service debt from operating income
Cap rate complements these metrics by focusing on the property’s operating efficiency rather than investor-specific factors.
Using Cap Rate for Property Valuation
Cap rate is commonly used in the income approach to valuation:
Property Value ≈ NOI ÷ Cap Rate
Because of this relationship, improving NOI through better management, reduced vacancy, or expense optimization can significantly increase a property’s estimated value.

Frequently Asked Questions
What is a good cap rate?
Cap rates vary by location, property type, and market conditions. Lower cap rates (3–5%) often indicate premium or low-risk markets, while higher cap rates (7–12%) may indicate higher risk or emerging markets.
Does cap rate include mortgage or EMI?
No. Cap rate uses NOI, which excludes debt service, income taxes, and capital expenditures. This allows investors to compare properties fairly regardless of financing.
Can cap rate be negative?
Yes. If the property’s NOI is negative due to high expenses or low rent, the resulting cap rate may also be negative. This typically indicates an unprofitable investment.
Does this tool store any data?
No. All calculations run locally in your browser, and nothing is saved or transmitted.
