Cap rate is one of the most frequently used terms in real estate investing, and one of the most frequently misunderstood. It appears in listing descriptions, broker offering memorandums, and investment analyses across every commercial property type, often without much explanation of what it actually measures or what a given number means in context.
At its core, cap rate answers a simple question: if you paid all cash for a property, what annual return would the income generate? That question strips out financing, taxes, and personal financial circumstances to produce a metric that reflects the property's income-generating ability relative to its price, making it one of the most useful tools for comparing properties and evaluating market conditions.
This guide covers what cap rate is, how to calculate it, what the numbers mean, and how it is used in real estate valuation and investment decisions.

What Is a Cap Rate in Real Estate?
Cap rate, short for capitalization rate, is a real estate valuation metric that measures the relationship between a property's net operating income and its market value or purchase price. It expresses that relationship as a percentage, showing what annual return the property would generate if purchased with all cash and no financing.
The formula is:
Cap Rate = Net Operating Income ÷ Property Value × 100
A property generating $80,000 in NOI purchased for $1,000,000 has a cap rate of 8%. That 8% represents the annual unlevered return on the investment before financing costs, taxes, and capital expenditures are considered.
Cap rate is a financing-neutral metric by design. Because it uses NOI before debt service, it reflects the property's income-generating ability independent of how it is financed.
Two investors who buy the same property at the same price, one with cash and one with a mortgage, will have the same cap rate but very different cash-on-cash returns depending on their financing structure. That financing neutrality is what makes cap rate the standard metric for comparing properties and markets on a consistent basis.
Cap rate also works in reverse as a valuation tool. Dividing a property's NOI by the market cap rate for comparable assets produces an estimate of the property's market value.
A property generating $120,000 in NOI in a market where comparable assets trade at a 6% cap rate has an implied value of $2,000,000. That relationship between NOI, cap rate, and value is the foundation of the income approach to commercial real estate valuation.
How to Calculate Cap Rate in Real Estate: The Formula
The cap rate formula is:
Cap Rate = Net Operating Income ÷ Property Value × 100
Net Operating Income is the property's annual income after all operating expenses are deducted but before debt service, depreciation, and taxes. It is calculated by taking effective gross income and subtracting property taxes, insurance, management fees, maintenance, utilities, and all other operating costs.
Property Value is either the current market value or the purchase price depending on the context. Use the purchase price when evaluating a potential acquisition. Use the current market value when assessing the ongoing performance of a property you already own.
Using Cap Rate to Determine Value
The formula can be reversed to estimate property value from NOI and a known market cap rate:
Property Value = NOI ÷ Cap Rate
A property generating $150,000 in NOI in a market where comparable assets trade at a 5.5% cap rate has an implied value of:
$150,000 ÷ 0.055 = $2,727,273
This reverse calculation is how appraisers and investors use cap rate as a valuation tool. Every dollar of NOI growth increases the property's implied value by 1 divided by the cap rate. At a 5.5% cap rate, each additional $10,000 of annual NOI adds approximately $181,818 in property value, which is why NOI improvement is such a powerful value creation lever in multifamily investing.

What Is a Good Cap Rate in Real Estate?
There is no single universally good cap rate. What constitutes a strong, acceptable, or weak cap rate depends on the property type, market, asset quality, and the investor's return requirements. Context determines whether a given cap rate represents an attractive opportunity or an overpriced asset.
General Benchmarks of Cap Rate in Real Estate by Property Type
These ranges reflect general market conditions as of 2026 and vary significantly by submarket, asset quality, and local supply and demand dynamics.
What a Low Cap Rate in Real Estate Signals
A low cap rate means the property is priced expensively relative to its current income. Investors are accepting a lower initial yield in exchange for something else, typically lower risk, stronger location, higher asset quality, or greater confidence in future income growth. Primary market Class A multifamily properties frequently trade at cap rates of 4% to 5% because investors are pricing in stability and long-term appreciation rather than high current income.
What a High Cap Rate in Real Estate Signals
A high cap rate means the property generates more income relative to its price. That higher initial yield typically reflects higher risk, whether in the form of older building stock, secondary market location, weaker tenant quality, or operational challenges that the market is pricing in through a discount to comparable assets. A high cap rate is not inherently attractive without understanding why it is high.
How Market Conditions Affect Cap Rates
Cap rates move inversely with property values and are directly influenced by interest rates. When borrowing costs rise, investors demand higher returns to offset the increased cost of capital, which pushes cap rates up and property values down. When rates fall, cheaper financing makes lower returns more acceptable, which compresses cap rates and pushes values up. The sharp interest rate increases between 2022 and 2024 pushed cap rates meaningfully higher across most property types, and the gradual rate moderation in 2025 and 2026 has begun to exert modest downward pressure on cap rates in well-leased, well-located assets.

Conclusion on Cap Rates in Real Estate
Cap rate is the most widely used metric in commercial real estate for good reason. It provides a consistent, financing-neutral basis for comparing properties, evaluating market conditions, and estimating value from income. Those three applications alone make it indispensable in any real estate analysis.
Its limitations are equally important to understand. Cap rate captures a property's current income relative to its price but says nothing about future income growth, financing costs, or total return over the hold period. Used alongside cash-on-cash return, IRR, and equity multiple, it gives investors the complete picture that no single metric can provide on its own.
Know what it measures, know what it doesn't, and use it accordingly.
Frequently Asked Questions on Real Estate Cap Rates
What Is a Good Cap Rate in Real Estate?
A good cap rate depends on the property type, market, and investment strategy. For multifamily, cap rates between 5% and 7% are generally considered reasonable in most markets, with Class A assets in primary markets trading closer to 4% to 5% and Class C assets in secondary markets ranging from 7% to 9%. There is no universal good cap rate without context around risk, location, and asset quality.
What Is a 7.5% Cap Rate?
A 7.5% cap rate means the property generates annual NOI equal to 7.5% of its purchase price. On a $1,000,000 property that translates to $75,000 in NOI per year on an all-cash basis before financing. A 7.5% cap rate is above average for most primary markets and typically reflects either a secondary market location, an older asset, higher perceived risk, or some combination of those factors.
What Does a 6% Cap Rate Mean in Real Estate?
A 6% cap rate means the property generates NOI equal to 6% of its value annually on an unlevered basis. On a $2,000,000 property that is $120,000 in annual NOI. A 6% cap rate sits in the moderate range for most commercial property types and is common for stabilized Class B multifamily assets in mid-tier markets where investors are accepting a moderate yield in exchange for reasonable stability and income predictability.
Is 7% a Good Cap Rate?
A 7% cap rate is generally considered solid for most commercial property types and markets. It indicates the property generates meaningful income relative to its price and provides more cushion above financing costs than lower cap rate assets in primary markets. Whether 7% is good depends on the specific property, the quality of the income, the market conditions, and how the cap rate compares to similar assets in the same submarket.
