What Is Cap Rate?
Cap rate, short for capitalization rate, is the single most referenced metric in commercial and residential real estate investing. It expresses the relationship between a property's net operating income (NOI) and its current market value as a simple percentage. A property generating $12,000 in annual NOI with a value of $200,000 has a cap rate of 6%.
The power of cap rate lies in its simplicity. By boiling down the income-to-value relationship into a single number, it lets investors quickly compare properties of different sizes, in different markets, and with different rent levels. A duplex in Memphis generating $9,000 NOI at a $150,000 price (6% cap) can be directly compared to a fourplex in Austin generating $18,000 NOI at a $360,000 price (5% cap) without needing to adjust for property size or financing.
Cap rate is also the primary metric used by appraisers, lenders, and institutional investors when evaluating commercial properties. If you ever plan to sell an investment property or refinance with a commercial lender, cap rate will be central to the conversation.
How to Use This Calculator
Net Operating Income (NOI)
Enter the property's annual net operating income. NOI is your total annual rental income minus all operating expenses (property taxes, insurance, maintenance, management fees, vacancy allowance, and utilities paid by the owner), but before mortgage payments, capital expenditures, or income taxes. If you do not know your NOI, use our NOI calculator to compute it.
Property Value
Enter the property's current market value or your negotiated purchase price. This is the full value of the property, not just your equity or down payment. Cap rate ignores how the property is financed, so the denominator is always the total property value.
How to Interpret Cap Rate
A higher cap rate means the property generates more income relative to its price, which typically indicates higher risk: the property may be in a less desirable area, have higher vacancy, or be in a market with weaker appreciation potential. A lower cap rate means the property generates less income relative to its price, which often indicates a safer, more stable investment in a strong market where investors accept lower current yields.
As a general guideline, cap rates in the 3%–5% range are common in expensive, low-risk primary markets; 5%–7% represents a middle ground; and 7%–10%+ is typical in secondary or tertiary markets where higher returns compensate for higher risk. These ranges are rough and shift over time with interest rates, market conditions, and investor sentiment.
When comparing properties, cap rate is most useful as a screening tool. If two similar properties in the same neighborhood have significantly different cap rates, the one with the higher cap rate is generating more income per dollar of value and may be the better deal (assuming the income and expenses are realistic).
The Formula
Cap Rate (%) = Net Operating Income / Property Value × 100
This formula is symmetrical: you can also rearrange it to estimate property value if you know the NOI and the cap rate for comparable properties. For example, if similar properties in your market sell at a 6% cap rate and a subject property has $15,000 in NOI, you can estimate the property value as $15,000 / 0.06 = $250,000.
Note that cap rate is calculated using annual NOI, not monthly. If your income and expense figures are monthly, multiply by 12 before dividing by the property value.
Examples by Market
Example 1: Primary Market (New York)
A condo in Manhattan generates $24,000 in annual NOI and is valued at $600,000. Cap rate: $24,000 / $600,000 = 4.0%. This low cap rate reflects the premium investors pay for a stable asset in a high-demand, low-vacancy market where long-term appreciation is the primary return driver.
Example 2: Secondary Market (Memphis)
A single-family rental generates $9,600 in annual NOI and is priced at $120,000. Cap rate: $9,600 / $120,000 = 8.0%. The higher cap rate compensates for higher vacancy risk, slower appreciation, and the general risk of investing in a less expensive market.
Example 3: Comparing Two Properties
Property A has an NOI of $18,000 and a price of $300,000 (6.0% cap). Property B has an NOI of $14,000 and a price of $200,000 (7.0% cap). Property B has a higher cap rate, meaning it generates more income per dollar of value. However, Property A might be in a stronger market with better appreciation prospects. Cap rate alone does not tell the full story; it tells you one dimension of it.
Tips and Limitations
Cap Rate Is Not the Whole Picture
Cap rate says nothing about appreciation, rent growth potential, the quality of the property, or the strength of the local economy. A 4% cap rate in a rapidly appreciating market can produce excellent total returns, while a 9% cap rate in a declining market can be a value trap. Always pair cap rate analysis with broader market research.
Verify the NOI
Cap rate is only as reliable as the NOI used to calculate it. Sellers and listing agents often present optimistic NOI figures that assume 100% occupancy and minimal maintenance. Do your own due diligence: verify actual rental income, check comparable rents, and budget realistic expenses.
Interest Rates Matter
Cap rates and interest rates are loosely correlated: when interest rates rise, cap rates tend to rise as well (and property values tend to fall), because investors demand higher yields to compensate for higher borrowing costs. This relationship is not perfect, but it is an important macro trend to be aware of.
Use Cap Rate for Screening, Not Deciding
Cap rate is an excellent first-pass screening tool that helps you quickly filter a long list of potential deals. But it should never be your sole decision-making metric. A property with a great cap rate can still be a bad investment if it has structural issues, is in a declining neighborhood, or has unrealistic income assumptions baked into the NOI.
Frequently Asked Questions
What is cap rate?
Cap rate, short for capitalization rate, is a percentage that represents the relationship between a property's net operating income (NOI) and its current market value or purchase price. It is the most widely used metric for comparing the relative value of different income-producing properties because it strips out financing differences and lets you compare properties on a pure income basis.
What is a good cap rate?
There is no universal "good" cap rate because it depends entirely on the market, the property type, and the risk profile. In expensive primary markets like New York or San Francisco, cap rates of 3%–5% are typical and still considered acceptable because property values tend to appreciate steadily. In secondary or tertiary markets, investors often demand 7%–10% to compensate for higher risk and slower appreciation.
Does a higher cap rate mean a better investment?
Not necessarily. A higher cap rate often signals higher risk: the property may be in a less desirable location, have higher vacancy, require more maintenance, or be in a market with weaker fundamentals. A lower cap rate can indicate a safer, more stable property in a strong market. The cap rate tells you about the relationship between price and income, not about the overall quality or safety of the investment.
How is cap rate different from cash-on-cash return?
Cap rate ignores financing entirely: it divides NOI by the full property value (purchase price). Cash-on-cash return accounts for your financing structure and divides annual cash flow by the cash you actually invested. Two properties with identical cap rates can produce very different cash-on-cash returns if one is financed with a large mortgage and the other is purchased with mostly cash.
Can I use cap rate to compare properties in different cities?
Yes, and that is one of cap rate's best use cases. By expressing the income-to-value relationship as a percentage, cap rate lets you compare a property in Dallas against one in Miami on equal footing. However, you should also consider market-specific factors like rent growth potential, property tax rates, and local economic conditions, none of which are captured by cap rate alone.
What expenses are included in NOI for cap rate?
NOI includes all operating expenses required to run the property: property taxes, insurance, maintenance and repairs, utilities (if paid by the owner), property management fees, and a vacancy allowance. It does not include mortgage payments (principal or interest), capital expenditures, income taxes, or depreciation. Excluding financing is what makes cap rate a pure measure of the property's income-generating ability.
Should I use asking price or market value for cap rate?
Use the property's actual market value, which may differ from the asking price. The asking price is what the seller wants; market value is what the property would sell for based on comparable transactions. For existing properties with known income, use the current market value. For new acquisitions, use your negotiated purchase price. Either way, consistency is key when comparing multiple properties.
How does cap rate change over time?
Cap rate changes when either the NOI or the property value changes. If rents and NOI increase while the property value stays the same, the cap rate rises. If property values appreciate faster than income grows (common in hot markets), the cap rate compresses. Cap rate compression is a common phenomenon in booming real estate markets where investor demand drives prices up faster than rents.
What is cap rate compression?
Cap rate compression occurs when cap rates decline over time in a market, typically because rising demand from investors pushes property prices higher without a proportional increase in rental income. It means investors are willing to accept lower current yields in exchange for perceived safety or future appreciation. Compression is common in gateway cities and during periods of low interest rates.
