Methodology: Cap Rate = NOI ÷ Property Value × 100. Property Value = NOI ÷ Cap Rate. NOI = Gross Rent × (1 − Vacancy%) − Operating Expenses − Property Management (% of effective gross income). Mortgage/debt service is explicitly excluded from NOI per industry standard.

How to Calculate Cap Rate for Real Estate
The capitalization rate (cap rate) is the single most widely used metric in commercial and residential real estate investment. It expresses the annual return a property would generate if purchased with 100% cash — no mortgage, no financing. This makes it a property-specific measure of yield that enables direct comparison between any two properties regardless of how they are financed.
The Three Cap Rate Formulas
Cap Rate = NOI ÷ Property Value × 100
Example: $24,000 NOI ÷ $300,000 property value = 8.0% cap rate
Property Value = NOI ÷ Cap Rate
Example: $36,000 NOI ÷ 0.07 (7% cap rate) = $514,286 estimated value
Used by appraisers as the income approach to commercial property valuation

NOI = Property Value × Cap Rate
Example: $400,000 value × 0.075 = $30,000 required annual NOI

How to Calculate Net Operating Income (NOI)
NOI is the foundation of the cap rate calculation. Getting it right is critical — sellers frequently inflate NOI by using projected (not actual) rents, excluding management fees, or omitting maintenance costs. Always verify NOI using the actual rent roll and 12-24 months of expense history.
NOI = Gross Rent − Vacancy − Operating Expenses
Operating Expenses INCLUDE: property taxes, insurance, property management (8-12% of rents), maintenance and repairs, utilities paid by owner, HOA fees, landscaping, pest control.
Operating Expenses EXCLUDE: mortgage principal and interest, depreciation, income taxes, capital expenditures, tenant improvements.

Cap Rate Benchmarks by Property Type and Market (2026)
| Property Type / Market | Typical Cap Rate | Assessment |
|---|---|---|
| Class A Multifamily, Major City | 4.0-5.0% | Low yield, high safety |
| Single-Family Rental, Suburban | 5.0-7.0% | Standard residential |
| Small Multifamily (2-4 units) | 5.5-7.5% | Good residential target |
| Strip Retail / NNN Lease | 5.5-7.5% | Depends on tenant quality |
| Industrial / Warehouse | 4.5-6.5% | Strong demand 2024-2026 |
| Secondary Market Multifamily | 6.0-8.5% | Higher yield, more risk |
| Value-Add / Class C | 8.0-11% | Significant risk/upside |
| Distressed / Turnaround | 10%+ | High risk, high potential |
Cap Rate vs. Cash-on-Cash Return vs. ROI
Real estate investors use multiple metrics and each measures something different. Cap rate measures the property's unlevered yield. Cash-on-cash measures the return on actual dollars invested (equity) after debt service. Total ROI includes appreciation, principal paydown, and tax benefits in addition to cash flow.
| Metric | What It Measures | Includes Mortgage? | Best For |
|---|---|---|---|
| Cap Rate | Property yield (no debt) | No | Comparing properties |
| Cash-on-Cash | Cash return on equity | Yes | Evaluating financing |
| GRM | Price vs gross rents | No | Quick screening |
| IRR | Total return over time | Yes | Long-term analysis |
💡 Investor Tip: Cap rate and interest rates move together. When the 10-year Treasury yield rises, cap rates typically follow — which means property values fall for the same NOI. In 2022-2023, rising rates from 0.5% to 5%+ compressed returns and caused cap rates to expand. Always check the current spread between cap rates in your market and the 10-year Treasury to assess relative value.
The 1% Rule and Cap Rate Relationship
The popular “1% rule” states that monthly rent should be at least 1% of the purchase price (e.g., $2,000/month rent on a $200,000 property). A property passing the 1% rule generates 12% gross yield — but after a 5% vacancy rate, 10% management, and other expenses, the cap rate is typically 6-8%. The 1% rule is a quick screening tool; cap rate is the accurate measure.
Frequently Asked Questions
Cap rate (capitalization 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 measures the expected annual return on a real estate investment assuming an all-cash purchase with no debt. Formula: Cap Rate = NOI / Property Value × 100.
A good cap rate depends on location and property type. Generally: 4-5% is typical for prime urban markets (low risk), 5-7% is average for suburban residential, 7-10% is strong for secondary markets, and above 10% may indicate higher risk or distressed properties. Most investors target 6-8% for single-family rentals.
Cap Rate = Net Operating Income (NOI) ÷ Current Property Value × 100. NOI = Gross Rental Income − Vacancy Losses − Operating Expenses (not including mortgage payments). Example: $24,000 NOI ÷ $300,000 value × 100 = 8% cap rate.
NOI is the annual income a property generates after deducting all operating expenses but before debt service (mortgage payments) and income taxes. NOI = Gross Rental Income − Vacancy Allowance − Operating Expenses. Operating expenses include property taxes, insurance, maintenance, property management fees, and utilities — but NOT mortgage principal and interest.
Cap rate measures return on total property value assuming no debt. Cash-on-cash return measures return on actual cash invested (your down payment) after accounting for mortgage payments. A property with an 8% cap rate financed with 25% down at a low interest rate might have a 10-14% cash-on-cash return due to leverage.
Property Value = NOI ÷ Cap Rate. If a property generates $36,000 NOI annually and comparable properties sell at a 7% cap rate, the estimated value = $36,000 ÷ 0.07 = $514,286. This is the income approach to property valuation used by commercial real estate appraisers.
Higher cap rates mean higher returns but typically indicate higher risk, lower-demand markets, or properties requiring more work. Lower cap rates indicate safer, more desirable markets. Investors seeking stability prefer lower cap rates in prime markets; investors seeking higher yields accept higher cap rates in secondary markets.
Commercial cap rates vary by asset class: Class A office in major cities 4-6%, retail strip centers 6-8%, industrial/warehouse 4-6%, apartment complexes 4-6%, and retail NNN leases 5-7%. Class B/C properties typically command 1-2% higher cap rates than Class A in the same market.
Cap rates and interest rates generally move in the same direction. When rates rise, cap rates tend to rise too (property values fall) because investors can earn better risk-free returns elsewhere and require higher yields from riskier real estate. The spread between cap rates and the 10-year Treasury yield is a key metric investors monitor.
NOI excludes: mortgage principal and interest payments, income taxes, depreciation, capital expenditures (major renovations), and tenant improvement allowances. These are excluded because cap rate measures property return independent of financing and ownership structure.
Cap rate compression occurs when cap rates decline (property values rise) while NOI stays constant. For example, if cap rates in a market move from 7% to 5%, property values increase by 40% for the same income. This happens when investor demand increases or interest rates fall. Cap rate compression is a major source of real estate appreciation.
Cap rate is excellent for quick property comparisons but has limitations. It does not account for financing, future rent growth, capital expenditures, or value-add potential. It also relies on accurate NOI, which sellers sometimes inflate. Always verify NOI with actual rent rolls and expense statements before making investment decisions.
