Capitalization Rate: Cap Rate Definition, Formula and Examples

The capitalization rate — almost always shortened to cap rate — is one of the most frequently used metrics in commercial real estate. It measures the relationship between a property’s income and its value, giving investors a quick way to compare properties, assess risk, and benchmark returns.

Understanding cap rate meaning isn’t complicated, but using it correctly requires knowing what it does and doesn’t tell you. This guide covers the definition, the formula, worked examples, benchmarks by property type, and the situations where cap rate falls short.

What is Cap Rate?

A cap rate is the ratio of a property’s net operating income (NOI) to its current market value or purchase price, expressed as a percentage. It represents the annualized return an investor would receive if they purchased a property with cash — no financing, no leverage.

In plain terms: if a property generates $80,000 in net operating income per year and sells for $1,000,000, the cap rate is 8%. That’s the unleveraged yield on that asset at that price.

Cap rate is used to:

• Estimate the value of an income-producing property
• Compare investment opportunities across different properties or markets
• Gauge risk — higher cap rates generally indicate higher risk and/or lower demand; lower cap rates suggest the opposite
• Track market trends over time within a specific submarket or asset class

Cap Rate Formula

The cap rate formula is:

Cap Rate = Net Operating Income (NOI) ÷ Current Market Value (or Purchase Price)

Or rearranged to solve for value:

Property Value = NOI ÷ Cap Rate

And to solve for NOI:

NOI = Property Value × Cap Rate

All three versions of the formula are useful depending on what you’re trying to determine.

Cap Rate: Worked Examples

Example 1 — Calculating cap rate from a known sale price:

A retail property sells for $2,000,000 and generates $140,000 in annual NOI.

Cap Rate = $140,000 ÷ $2,000,000 = 7.0%

Example 2 — Calculating property value from a known cap rate:

A similar retail property in the same submarket generates $160,000 in NOI. The market cap rate for comparable assets is 7.0%.

Property Value = $160,000 ÷ 0.07 = $2,285,714

Example 3 — Impact of NOI change on value:

The same property increases NOI to $175,000 through a rent increase. At the same 7.0% cap rate:

Property Value = $175,000 ÷ 0.07 = $2,500,000

That $15,000 increase in annual NOI — roughly a 9.4% income increase — produced a $214,286 increase in property value. This is why NOI growth is so central to commercial real estate investment strategy.

How to Calculate NOI

NOI is the starting point for any cap rate calculation. It’s calculated as:

NOI = Gross Operating Income − Operating Expenses

Gross operating income includes:

• Actual rent collected from occupied units
• Market rent for vacant units (gross potential rent)
• Additional income (parking, laundry, storage, etc.)
• Less vacancy and credit loss allowance

Operating expenses include:

• Property taxes
• Insurance
• Utilities (landlord-paid)
• Maintenance and repairs
• Property management fees
• Administrative costs

What NOI does not include: mortgage payments, depreciation, capital expenditures, or income taxes. These are excluded to keep NOI a clean measure of the property’s operating performance independent of how it’s financed.

What Is a Good Cap Rate?

There’s no single answer — a “good” cap rate depends on the property type, market, location, and the investor’s risk tolerance and return requirements. That said, here are general benchmarks for U.S. markets:

By property type:

• Multifamily (apartment): 4%–6% in primary markets; 5%–8% in secondary/tertiary markets
• Industrial/warehouse: 4.5%–6.5%, with significant compression in recent years driven by e-commerce demand
• NNN retail (single-tenant): 4.5%–7%, depending on tenant credit quality and lease term
• Office: 5.5%–8%+, with significant variation based on occupancy, market, and asset class
• Retail (multi-tenant): 6%–9%, reflecting higher operational complexity and vacancy risk
• Hospitality: 7%–10%+, reflecting higher operational risk

By market tier:

• Primary markets (San Francisco, New York, Los Angeles, Boston): compressed cap rates — 4%–5.5% for core assets — reflecting high demand and lower perceived risk
• Secondary markets (Denver, Austin, Nashville, Seattle): 5%–7%, a middle ground of growth and risk
• Tertiary markets: 7%–10%+, higher yields to compensate for lower liquidity and demand

The inverse relationship between cap rates and property values is fundamental: when cap rates compress (fall), values rise. When cap rates expand (rise), values fall. This is why cap rate trends in a submarket are closely watched as a leading indicator of value movement.

Cap Rate Meaning: What High vs. Low Cap Rates Signal

A lower cap rate means an investor is paying more for each dollar of income — typically because the asset is perceived as lower risk, the market is highly liquid, or future income growth is expected to be strong. Core assets in primary markets trade at low cap rates for this reason.

A higher cap rate means an investor is paying less per dollar of income — reflecting higher perceived risk, lower liquidity, weaker market fundamentals, or a property that requires significant management or capital expenditure to stabilize.

Neither is inherently better. A 4% cap rate in San Francisco might represent an excellent risk-adjusted return for a core institutional buyer. The same cap rate in a secondary city might be significantly overpriced. Context is everything.

Entry Cap Rate vs. Exit Cap Rate

Two specific applications of cap rate matter in any investment underwriting:

The entry cap rate (also called the going-in cap rate) is the cap rate at acquisition — calculated using the property’s projected first-year NOI and the purchase price. It establishes the initial yield and is used to assess whether the entry price is appropriate for the risk.

The exit cap rate (also called the terminal or going-out cap rate) is the cap rate applied at the projected sale of the property at the end of the holding period. It’s used to estimate the future sale price in a DCF analysis.

The spread between entry and exit cap rate matters significantly. If you buy at a 6% cap rate and the market has compressed to 5% by the time you sell, your property has appreciated beyond just income growth. If cap rates have expanded to 7% at exit, you face a headwind on value regardless of how well the property performed operationally.

When to Use Cap Rate — and When Not To

Cap rate works well for:

• Quick comparison of similar stabilized properties in the same market
• Estimating value when a reliable NOI figure is available
• Tracking submarket trends over time
• Back-of-envelope feasibility analysis

Cap rate is unreliable for:

• Properties with unstable or irregular income — high vacancy, lease-up assets, or properties with near-term lease expirations
• Short-term holds where timing of cash flows matters significantly
• Properties with significant deferred capital expenditure that isn’t reflected in current NOI
• Highly leveraged deals where financing terms materially affect returns
• Development projects or value-add assets where income is projected, not stabilized

In these situations, a full discounted cash flow (DCF) analysis — which models all cash flows over the holding period, including capital events, lease-up, and the terminal sale — provides a more accurate and complete picture of investment performance.

Frequently Asked Questions

What is cap rate in real estate? Cap rate is the ratio of a property’s annual net operating income to its current market value or purchase price, expressed as a percentage. It measures the unleveraged return on an income-producing property.

What is the cap rate formula? Cap Rate = Net Operating Income ÷ Current Market Value. It can be rearranged to solve for property value (NOI ÷ Cap Rate) or NOI (Value × Cap Rate).

What is a good cap rate? It depends on property type, market, and risk tolerance. In primary U.S. markets, core assets typically trade between 4%–6%. Secondary markets range from 5%–7%. Higher cap rates indicate higher risk and/or lower market demand.

What is cap rate meaning in practice? A cap rate tells you the annual return you’d earn on a property if you bought it with all cash. It’s primarily a comparison and valuation tool — not a complete measure of investment performance, which requires accounting for financing, capital expenditure, and future income changes.

What’s the difference between cap rate and ROI? Cap rate measures unleveraged operating yield — it excludes financing. ROI (return on investment) typically accounts for leverage, cash flow after debt service, and total capital invested. A property can have a 5% cap rate but a much higher cash-on-cash return if it’s financed with low-interest debt.

Does cap rate include mortgage payments? No. NOI — the numerator in the cap rate formula — excludes debt service. Cap rate is a pre-financing metric, which is what makes it useful for comparing properties regardless of how they’re financed.
