How to Calculate Cap Rate for Commercial Real Estate
The step-by-step formula, worked examples, and practical guidance every investor needs to evaluate commercial property returns using capitalization rate.
What is cap rate?
Capitalization rate, cap rate, is the most widely used metric in commercial real estate for comparing properties and understanding market pricing. It measures the relationship between a property’s net operating income and its purchase price or market value, expressed as a percentage.
Cap rate answers a simple question: if you bought this property with cash (no mortgage), what annual return would the operating income generate on your investment? It strips out financing, making it useful for apples-to-apples comparison between properties regardless of how each deal is structured.
The cap rate formula
Capitalization rate
Cap Rate = Net Operating Income ÷ Purchase Price
Expressed as a percentage
The formula has only two inputs, but both require careful definition. Net operating income (NOI) is the property’s annual gross revenue minus operating expenses, before debt service, capital expenditures, and income taxes. The purchase price (or current market value for existing holdings) is the denominator.
Getting NOI right is where most mistakes happen. You need to include all income (base rent, CAM reimbursements, parking, percentage rent) and subtract all operating expenses (property taxes, insurance, maintenance, management fees, utilities paid by the landlord). Do not include mortgage payments, depreciation, or capital improvements in the NOI calculation. Those are below the NOI line.
Worked examples
Three real deal shapes, three different answers: same formula.
Industrial Warehouse: Houston, TX
7.5% cap rate
A 40,000 SF industrial building with three tenants on NNN leases. Annual gross rent of $380,000, operating expenses of $95,000 (paid by tenants via NNN pass-throughs, landlord responsible for structural reserves and management). NOI of $285,000 ÷ $3,800,000 = 7.5% cap rate. This is consistent with Class B industrial pricing in secondary Texas markets.
Retail Strip Center: Orlando, FL
7.0% cap rate
A 12,000 SF neighborhood retail center with five tenants. Gross rent of $240,000, operating expenses of $72,000 (taxes, insurance, CAM, management). NOI of $168,000 ÷ $2,400,000 = 7.0% cap rate. Retail centers in strong suburban locations typically trade in the 6.5% to 8.0% range depending on tenant quality and lease term.
Class A Office: Denver, CO
6.0% cap rate
A 50,000 SF Class A office building with a single credit tenant on a 10-year lease. Gross rent of $1,250,000, operating expenses of $500,000 (full-service gross lease, landlord covers most expenses). NOI of $750,000 ÷ $12,500,000 = 6.0% cap rate. Single-tenant credit office assets command tighter cap rates due to lower risk.

The cap rate formula works in reverse for valuation. If you know a property’s NOI and the market cap rate for comparable properties, you can estimate value:
Property value estimate
Value = NOI ÷ Cap Rate
For example, an industrial property generating $300,000 NOI in a market where comparable industrial assets trade at 7.0% cap rates would be valued at approximately $300,000 ÷ 0.07 = $4,285,714. If the same property were in a tighter market where industrial trades at 5.5%, the implied value jumps to $5,454,545.
This is why cap rate movements matter so much to property values. A 100 basis point compression in cap rates (from 7.0% to 6.0%) on a $300,000 NOI property increases the value from $4.3M to $5.0M, a 16% gain without any change in income. Conversely, cap rate expansion destroys value even when NOI is growing.
Cap rate ranges by asset class
| Asset class | Typical cap rate range | Key drivers |
|---|---|---|
| Multifamily (Class A) | 4.0% – 5.5% | Consistent demand, lower vacancy risk, agency financing availability |
| Multifamily (Class B/C) | 5.5% – 7.5% | Value-add potential, higher turnover, renovation upside |
| Industrial / Warehouse | 5.5% – 7.5% | E-commerce demand, low maintenance, long lease terms |
| Retail (Strip Center) | 6.5% – 8.5% | Tenant mix, lease rollover risk, location quality |
| Office (Class A) | 5.5% – 7.0% | Tenant credit, lease length, market fundamentals |
| Office (Class B/C) | 7.0% – 9.5% | Remote work impact, capital needs, functional obsolescence |
Note: These ranges are approximate and vary significantly by market, submarket, property condition, and tenant quality. Always research local comparables.
What cap rate doesn't tell you
Cap rate is a useful screening tool, but it has real limitations that experienced investors understand:
It ignores financing
Cap rate measures unleveraged yield. Two investors buying the same property at the same cap rate will have very different actual returns depending on their loan terms. Cash-on-cash return and IRR capture what cap rate misses.
It's a snapshot, not a projection
Cap rate reflects today's NOI against today's price. It doesn't account for rent growth, lease rollover, capital expenditure needs, or vacancy trends. A property with a 7% cap rate and a tenant leaving in 6 months is very different from one with a 7% cap rate and 10 years of remaining lease term.
It doesn't measure total return
Cap rate ignores appreciation, depreciation tax benefits, mortgage principal paydown, and capital improvement value creation. A property with a low cap rate in a high-growth market may deliver better total returns than a high cap rate property in a declining market.
This is why serious underwriting goes beyond cap rate. You need to model the full cash flow timeline, debt service, exit assumptions, and internal rate of return to truly evaluate a deal.
Frequently asked questions
What is a good cap rate for commercial real estate?
There's no universal answer: it depends on the asset class, market, property condition, and risk profile. Generally, lower cap rates (4%–6%) indicate lower-risk, higher-priced properties in strong markets. Higher cap rates (7%–10%) suggest more risk, more upside, or weaker markets. A 'good' cap rate is one that aligns with your return targets and risk tolerance after accounting for financing, capital needs, and market trajectory.
Is a higher or lower cap rate better?
From a buyer's perspective, a higher cap rate means you're paying less per dollar of income, more yield for your money. But higher cap rates usually come with more risk: shorter leases, weaker tenants, secondary locations, or deferred maintenance. Lower cap rates mean you're paying a premium for stability. Neither is inherently better. The right cap rate depends on your investment strategy.
How does cap rate relate to interest rates?
Cap rates and interest rates tend to move in the same direction over time, but not in lockstep. When interest rates rise, borrowing becomes more expensive, which reduces buyer demand and pushes cap rates up (lowering property values). When rates fall, cap rates tend to compress. The spread between cap rates and prevailing interest rates is a key indicator of market health, tighter spreads mean less margin for error.
Should I use in-place NOI or stabilized NOI for cap rate?
It depends on the context. In-place (or going-in) cap rate uses current actual NOI. What the property earns today. This is the most conservative approach and reflects reality. Stabilized cap rate uses projected NOI after the property is fully leased and operating at market rents. Stabilized cap rates are useful for evaluating value-add deals but can be misleading if your assumptions about lease-up timing and market rents are aggressive.
Can I use cap rate for residential properties?
Cap rate can technically be calculated for any income-producing property, but it's primarily used in commercial real estate. Residential properties (1-4 units) are typically valued using comparable sales rather than income capitalization. Once you get into 5+ unit multifamily, cap rate becomes the standard valuation metric.
Final thoughts
Cap rate is the starting point for every commercial real estate conversation, but it’s just that, a starting point. Use it to screen deals, compare properties, and understand market pricing. Then go deeper: model the full cash flow, stress-test your assumptions, calculate your leveraged returns, and evaluate the exit.
