NOI Formula, Property Valuation from Cap Rate, and 2025 Benchmarks by Property Type
A 10-unit apartment building generating $168,000 in gross rents with $49,368 in operating expenses produces an NOI of $110,232. At a $1,200,000 purchase price, the cap rate is 9.19%. If the market cap rate for comparable properties is 6.5%, the income approach values the same building at $1,695,877 — a $495,877 premium over the asking price. Whether the cap rate is used to underwrite a new purchase, value an existing holding, or assess a potential sale, the same two formulas govern: Cap Rate = NOI / Value (to assess current yield) and Value = NOI / Market Cap Rate (to derive implied valuation).
The capitalization rate is the most fundamental valuation metric in commercial and income-producing real estate. It represents the unlevered return generated by a property at its current operating income — stripping out the effects of financing to provide a clean comparison between properties regardless of how each is funded. A property generating $110,232 in Net Operating Income purchased for $1,200,000 has a cap rate of 9.19%: if you owned the property free and clear with no mortgage, that 9.19% would be your annual return on the invested capital before income taxes and depreciation.
The cap rate functions as both a yield measure and a valuation tool. As a yield measure, it answers “what return does this property produce at this price?” As a valuation tool (Value = NOI / Market Cap Rate), it answers “what would a knowledgeable buyer pay for a property generating this NOI in this market?” Commercial appraisers call this the income capitalization approach, and it is the primary method for valuing income-producing commercial properties — applied whenever the comparable sales approach lacks sufficient data or the income stream is the property’s primary value driver. Understanding both directions of the cap rate formula is essential for anyone buying, selling, financing, or appraising income-producing real estate.
Three Cap Rate Formulas: Cap Rate, Property Value, and NOI Calculation
Cap rate analysis requires three formulas: the basic cap rate calculation from NOI and value, the reverse valuation from NOI and market cap rate, and the NOI calculation from gross income and operating expenses.
1. CAP RATE (YIELD DIRECTION)
2. PROPERTY VALUE (VALUATION DIRECTION)
3. NET OPERATING INCOME (NOI CALCULATION)
EGI = Gross Potential Rent – Vacancy + Other Income
The NOI formula’s explicit exclusion of debt service (mortgage payments) is the most important technical detail in cap rate analysis. Including mortgage payments in operating expenses would produce a property-specific metric that varies with the financing structure — making it impossible to compare properties with different leverage levels. By calculating NOI before debt service, the cap rate becomes a pure measure of the property’s income-generating performance at market values, independent of how any particular buyer has chosen to finance it. Two identical buildings with identical rents and expenses have identical cap rates regardless of whether one is owned free and clear and the other carries a $900,000 mortgage.
Four Cap Rate Scenarios: NOI Build, Valuation, Sensitivity, and Leverage Analysis
The four cards below model the complete cap rate workflow for the 10-unit apartment building: building the NOI from gross rent, deriving the implied valuation from market cap rates, showing cap rate sensitivity, and comparing cap rate to cash-on-cash return with leverage.
The fourth card’s positive leverage example illustrates the fundamental relationship between the cap rate and the mortgage rate. When the cap rate (9.19%) exceeds the mortgage rate (6.80%), debt enhances returns — every dollar of mortgage financing earns 9.19% in property income while costing only 6.80% in interest, with the 2.39% difference flowing to equity. The result: cash-on-cash return (14.6%) exceeds the cap rate (9.19%) by 5.4 percentage points due to positive leverage. When this relationship reverses — as it has in many commercial markets where Class A cap rates of 4.5-5.5% are below current 6.80% mortgage rates — debt destroys returns, and cash-on-cash falls below the cap rate. This negative leverage environment has been the defining challenge in commercial real estate transactions since rates rose in 2022.

Open the Cap Rate CalculatorComplete NOI Calculation: 10-Unit Apartment Building
The data block below builds the complete NOI calculation from gross rent through every operating expense category for the 10-unit apartment building, producing the NOI used in both the cap rate and valuation formulas.
The data block’s expense ratios are worth examining as percentages of EGI to establish benchmarks: property taxes ($18,000) represent 11.3% of EGI, insurance ($5,000) is 3.1%, management ($12,768) is 8%, maintenance ($8,000) is 5%, utilities ($3,600) is 2.3%, and administrative ($2,000) is 1.3%. Total expenses ($49,368) are 30.9% of EGI, producing an expense ratio of 30.9% and NOI representing 69.1% of EGI. For multifamily properties, an expense ratio of 35-45% of EGI is typical in most US markets. The 30.9% in this example is below average, suggesting either a newer property with low maintenance needs, a market with below-average property taxes, or an owner managing without a management company. Sellers of investment properties frequently present optimistic NOI projections by understating expenses — verifying each expense line against actual historical data or market norms is essential in underwriting.
2025 Cap Rate Benchmarks by Property Type
Market cap rates in 2025 vary significantly by property type, quality class, and geographic market. The table below provides approximate cap rate ranges for major commercial property types in typical US markets, serving as a starting point for benchmarking specific properties against sector norms.
| Property Type | Quality Class | 2025 Cap Rate Range | Key Drivers | Leverage at 6.80% Rate | Value Sensitivity (per 1% cap rate change) |
|---|---|---|---|---|---|
| Multifamily Apartment | Class A | 4.5-5.5% | Urban core, new construction, high demand | Negative (cap rate below 6.80%) | Large (18-22x NOI change per 1%) |
| Multifamily Apartment | Class B | 5.5-6.5% | Suburban, 1990s-2000s vintage | Near neutral | Large (15-18x) |
| Multifamily Apartment | Class C | 6.5-8.0% | Value-add, older buildings | Positive | Moderate (12-15x) |
| Industrial / Logistics | Class A | 5.0-6.0% | Last-mile, e-commerce demand | Near neutral | Large (17-20x) |
| Industrial | Class B/C | 6.0-7.5% | Older flex, secondary markets | Positive | Moderate |
| NNN Net Lease Retail | Investment Grade | 5.5-6.5% | Long-term credit tenant (CVS, Walgreens) | Near neutral | Large (15-18x) |
| Strip Mall / Neighborhood Retail | Class B | 6.5-8.0% | Grocery-anchored, suburban | Positive | Moderate |
| Office | Class A | 6.0-8.0% | Suburban CBD, post-pandemic uncertainty | Ranges positive to negative | Moderate-Large |
| Office | Class B/C | 8.0-11.0% | Conversion risk, high vacancy | Positive (but high risk) | Moderate (9-12x) |
| Self-Storage | Market rate | 5.5-7.0% | Recession resistant, e-commerce adjacency | Near neutral to positive | Large (14-18x) |
| Approximate 2025 US market cap rates. Actual rates vary by specific metro area, submarket, property condition, and lease structure. Gateway markets (NYC, LA, SF) typically have cap rates 0.5-1.5% lower than secondary markets. Cap rate ranges reflect available transactions — some sectors (particularly office) have limited transaction volume in 2025 making cap rate discovery difficult. “Value Sensitivity” shows approximately how much property value changes per $1 of NOI change at the given cap rate range (higher multiples = more sensitive to NOI changes). Negative leverage = property cap rate below 6.80% mortgage rate; positive leverage = cap rate above mortgage rate. | |||||
The cap rate table’s leverage column is the most practically important feature in the current rate environment. At 6.80% mortgage rates, only properties with cap rates above approximately 7% produce positive leverage — meaning the cap rate exceeds the borrowing cost and debt enhances cash-on-cash returns. Most Class A multifamily (4.5-5.5% cap) and industrial (5.0-6.0% cap) properties have cap rates below the current mortgage rate, producing negative leverage. Buyers of these assets typically justify the negative leverage through expected NOI growth (rent increases) and appreciation — a thesis that is defensible in supply-constrained markets with strong demand fundamentals but requires a longer hold horizon and higher NOI growth assumptions than the first-year cap rate implies.
Cap Rate Sensitivity Analysis: Value Impact by Cap Rate and NOI Level
| Annual NOI | At 5.0% Cap | At 6.0% Cap | At 7.0% Cap | At 8.0% Cap | At 9.0% Cap | At 10.0% Cap |
|---|---|---|---|---|---|---|
| $50,000 | $1,000,000 | $833,333 | $714,286 | $625,000 | $555,556 | $500,000 |
| $75,000 | $1,500,000 | $1,250,000 | $1,071,429 | $937,500 | $833,333 | $750,000 |
| $110,232 | $2,204,640 | $1,837,200 | $1,574,743 | $1,377,900 | $1,224,800 | $1,102,320 |
| $150,000 | $3,000,000 | $2,500,000 | $2,142,857 | $1,875,000 | $1,666,667 | $1,500,000 |
| $200,000 | $4,000,000 | $3,333,333 | $2,857,143 | $2,500,000 | $2,222,222 | $2,000,000 |
| $300,000 | $6,000,000 | $5,000,000 | $4,285,714 | $3,750,000 | $3,333,333 | $3,000,000 |
| Property Value = NOI / Cap Rate. The $110,232 NOI row corresponds to the 10-unit apartment building example. Color coding: green = typical Class A/B multifamily and industrial cap rates (4.5-6.5%); blue = mid-market cap rates (6.0-7.0%); amber = higher cap rates associated with value-add or secondary markets (8-10%). Key insight: a $50,000 difference in NOI changes property value by $500,000-$1,000,000 depending on the cap rate. Accurate NOI calculation is therefore critical — a $5,000/year expense omitted from the NOI calculation inflates the implied property value by $50,000-$100,000 at typical cap rates. | ||||||
The sensitivity table’s footnote contains the most important due diligence insight: a $5,000 error in NOI calculation inflates or deflates the implied property value by $50,000-$100,000 at typical cap rates. At a 5% cap rate, $5,000 of NOI = $100,000 in value. This explains why sellers present optimistic NOI by understating expenses (below-market management fees, no vacancy allowance, deferred maintenance not reflected in expense load) — each dollar of artificially inflated NOI multiplies into substantial additional implied value through the cap rate division. Buyers must verify every line of the NOI pro forma against actual historical expenses, tax records, and market-rate comparable operating costs.
Property Value at Different Cap Rates: NOI $110,232
The growth bars show the dramatic range in implied property value for the same $110,232 NOI at different market cap rates, illustrating why cap rate selection is the most consequential variable in the income approach valuation.
The growth bars make the cap rate’s value impact visually explicit: the same $110,232 NOI ranges from $1.10M in value (at a 10% cap rate) to $2.20M (at a 5% cap rate) — a 2x difference purely from the cap rate selection. This range is not hypothetical: the same 10-unit apartment building in a gateway market (New York City, San Francisco, Boston) might trade at a 4.5-5% cap rate while an identical building in a secondary market (Memphis, Tucson, Springfield) might trade at 8-9%. Location-driven cap rate differences are the largest single source of property value variation in commercial real estate, dwarfing differences in property size, age, or condition in most markets.
Common NOI Calculation Errors That Inflate Cap Rate
Five Ways Sellers Inflate NOI to Justify Higher Asking Prices
1. Below-market management fees: sellers sometimes use a 4-5% management fee in the pro forma when market rates are 8-10%. At $159,600 EGI, using 4% instead of 8% inflates NOI by $6,384 — equivalent to $98,000-$128,000 in property value at 5-6.5% cap rates. 2. Omitted vacancy allowance: some pro formas present 100% occupancy with zero vacancy provision. A realistic 5-7% vacancy allowance on $168,000 GPR reduces NOI by $8,400-$11,760. 3. Deferred maintenance not in expense load: a property with deferred paint, roof, or HVAC work presents below-market maintenance expenses until the capital spending hits. Buyers should normalize maintenance to 1-2% of property value annually. 4. Owner-occupied management: when the owner self-manages, no management fee appears in operating expenses. Buyers who cannot self-manage must add market-rate management fees (8-10% of EGI) to the true expense load. 5. Seller-paid utilities included in buyer’s NOI: some pro formas include utilities the seller pays that will transfer to tenants or fall on the buyer differently. Verify utility expense responsibility at closing.
Cap Rate vs Cash-on-Cash vs IRR: Choosing the Right Metric
Cap Rate, Cash-on-Cash Return, and IRR: When to Use Each
Cap Rate (NOI / Value): Use for initial screening and comparison between properties on an unlevered basis. Cap rate allows comparison across properties with different financing. It does not reflect the investor’s actual cash return if the property is financed. Best for: quick underwriting of value and market comparisons. Cash-on-Cash Return (Pre-Tax Cash Flow / Equity): Use to assess the actual first-year return on invested equity after debt service. Positive leverage (cap rate above mortgage rate) makes cash-on-cash exceed the cap rate; negative leverage makes cash-on-cash lower. Best for: comparing leveraged investment alternatives and setting minimum return thresholds. Internal Rate of Return (IRR over hold period): Use for multi-year underwriting that captures rent growth, refinancing, and appreciation. IRR requires a hold period assumption and exit cap rate projection. Best for: full investment underwriting when acquisition, operations, and exit are all modeled together. The typical professional underwriting sequence: cap rate for initial screening, cash-on-cash for first-year leverage analysis, IRR for full-hold-period investment decision.
Cap Rate Analysis Checklist
Frequently Asked Questions: Capitalization Rate Calculator
What is the capitalization rate formula?+
Cap Rate = NOI / Current Property Value. NOI = EGI – Operating Expenses. EGI = Gross Potential Rent – Vacancy + Other Income. Operating Expenses include all costs except debt service. Example: 10-unit apartment, GPR $168,000, vacancy $8,400, EGI $159,600, expenses $49,368, NOI $110,232. At $1,200,000: Cap Rate = $110,232 / $1,200,000 = 9.19%. Reverse direction for valuation: Value = NOI / Market Cap Rate. At 6.5% market cap: $110,232 / 0.065 = $1,695,877. Cap rate is an unlevered metric — mortgage payments are never included in operating expenses. This allows comparison of properties regardless of how they are financed.
What is a good cap rate for investment property?+
“Good” cap rate depends on property type, location, and risk tolerance. 2025 approximate ranges: Multifamily Class A: 4.5-5.5% (expensive but low risk). Multifamily Class B: 5.5-6.5%. Industrial: 5.0-6.0%. NNN net lease: 5.5-7.0%. Retail strip: 6.5-8.0%. Office Class A: 6.0-8.0%. Office Class B: 8.0-11.0%. At 6.80% mortgage rates, cap rates below 6.80% produce negative leverage — cash-on-cash return falls below cap rate when financing is used. Cap rates above 6.80% produce positive leverage. A 9.19% cap rate in a secondary market apartment deal is excellent; the same 9.19% on office space in a declining market may be fair compensation for substantial risk.
How do you calculate NOI for a rental property?+
NOI = Gross Potential Rent – Vacancy – Operating Expenses (excluding mortgage). Steps: (1) GPR: all units at full occupancy at market rents. (2) EGI = GPR – Vacancy Allowance (5-10%). (3) Add other income (parking, storage, laundry). (4) Subtract operating expenses: property taxes, insurance, management fees (8-10% of EGI), maintenance (1-2% of value annually), landlord-paid utilities, accounting/legal, reserves. NOI = EGI – Total Operating Expenses. What NOT to include: mortgage principal and interest, depreciation, income taxes, capital improvements. Critical: sellers frequently present below-market expenses (no management fee if self-managing, no vacancy allowance, deferred maintenance excluded) to inflate NOI and justify higher asking price. Always normalize to market-rate expenses.
How do you use cap rate to value a property?+
Value = NOI / Market Cap Rate. This is the income capitalization approach used by commercial appraisers. The market cap rate comes from recent comparable sales (find 3-5 recent sales of similar properties, calculate each as Sale NOI / Sale Price, average the results). Example: $110,232 NOI, market cap rate 6.5%: Value = $110,232 / 0.065 = $1,695,877. Cap rate sensitivity is significant: at 5.5% cap rate, same NOI = $2,004,218 (+$308K); at 7.5% = $1,469,760 (-$226K). A 2% cap rate spread produces $534K in value difference on the same NOI. The accuracy of the income approach depends on: (1) accurate NOI calculation and (2) accurate market cap rate from true comparable sales.
What is the difference between cap rate and cash-on-cash return?+
Cap rate: NOI / Property Value (unlevered, ignores financing). Cash-on-cash: (NOI – Debt Service) / Equity Invested (includes financing). Example: $1,200,000 property, $110,232 NOI, 20% down ($240,000), $960,000 mortgage at 6.80% ($75,204/yr). Cap rate: $110,232 / $1,200,000 = 9.19%. Cash flow: $110,232 – $75,204 = $35,028. Cash-on-cash: $35,028 / $240,000 = 14.6%. Positive leverage (cap rate 9.19% > mortgage 6.80%) causes cash-on-cash (14.6%) to exceed cap rate (9.19%). At cap rates below the mortgage rate (negative leverage), cash-on-cash falls below the cap rate. Cap rate is for property comparison; cash-on-cash is for investment return assessment.
What cap rate should I buy at?+
Target cap rate depends on mortgage rate, required return, and risk tolerance. Key benchmark: buy at cap rates above your mortgage rate for positive leverage (debt enhances returns). At 6.80% mortgage rate: cap rates above 7% produce positive leverage. Below 6.80% (Class A multifamily at 4.5-5.5%): negative leverage requires NOI growth thesis to justify. For all-cash investors: cap rate should exceed your minimum required unlevered return (typically 5-8%+). For leveraged investors: minimum cap rate = mortgage rate + desired spread (typically 1-2%). During high-rate environments (2023-2025): positive leverage properties are scarce, suppressing transaction volume. Investors accepting negative leverage must project above-market NOI growth and cap rate compression to achieve target returns.
What is cap rate compression?+
Cap rate compression = cap rates falling over time, causing property values to rise even with unchanged NOI. $100,000 NOI at 7.0% cap = $1,428,571. Same $100,000 NOI at 5.0% cap = $2,000,000. The $571,429 value increase required no income growth — only market cap rate compression from 7% to 5%. This occurred dramatically in multifamily and industrial from 2015-2022, driven by low interest rates and institutional capital demand. Cap rate expansion (rising cap rates) causes values to fall: $100,000 NOI at 5% = $2M, but at 7.5% = $1,333,333 — a 33% value decline from cap rate expansion alone, with no income change. The 2022-2024 rate environment caused significant cap rate expansion, reversing much of the 2015-2022 compression gains.
What expenses are included in NOI?+
INCLUDED in operating expenses (deducted from EGI to get NOI): Property taxes. Hazard insurance. Property management fees (5-10% of EGI). Maintenance and routine repairs. Landlord-paid utilities. Landscaping, snow removal. Advertising, leasing commissions (amortized). Accounting, legal, administrative. Capital replacement reserves (some investors include, some exclude). NOT INCLUDED (never deducted): Mortgage principal and interest (debt service). Depreciation. Income taxes. Capital improvements (added to basis). Investor’s personal expenses. The exclusion of debt service is what makes NOI an unlevered metric — enabling cap rate comparison across properties with different financing structures. Always confirm whether reserves are included or excluded when receiving a cap rate from a broker or seller.
How does cap rate change with interest rates?+
Cap rates generally move in the same direction as long-term interest rates, but with a lag and imperfectly. When rates rise: commercial real estate becomes less attractive relative to risk-free rates (Treasury bonds) at existing prices — pushing buyers to demand higher cap rates (lower prices) to compensate. This cap rate expansion reduces property values for the same NOI. When rates fall: cap rates compress as real estate becomes more attractive relative to lower-yielding fixed income alternatives. The relationship is not 1:1 — cap rates typically move 50-70% of the magnitude of Treasury rate changes, with a 6-18 month lag reflecting the illiquid nature of commercial real estate transactions. From 2022-2024, 10-year Treasury yields rose approximately 2.5-3%, and commercial cap rates expanded approximately 1.0-1.5% across most property types, with office markets expanding 2%+ due to additional demand destruction.
Key Takeaways
The capitalization rate formula operates in two directions: Cap Rate = NOI / Value (to assess the yield on a specific property at a specific price) and Value = NOI / Market Cap Rate (to derive the income approach valuation from market-rate comparables). NOI is calculated as Effective Gross Income (Gross Potential Rent minus Vacancy) minus all operating expenses except debt service. On the 10-unit apartment example, $168,000 in gross rent minus $8,400 in vacancy and $49,368 in operating expenses produces $110,232 in NOI — a 9.19% cap rate at the $1,200,000 purchase price and $1,695,877 in implied value at the 6.5% market cap rate.
The three most consequential cap rate analysis principles are: NOI accuracy is paramount (each $1 of incorrectly calculated NOI changes implied value by $14-$20 depending on the cap rate), the leverage relationship between the cap rate and the mortgage rate determines whether debt enhances or erodes cash-on-cash returns (positive leverage when cap rate exceeds mortgage rate, negative when below), and the exit cap rate assumption in a hold-period IRR analysis has as much impact on total returns as the acquisition cap rate and NOI growth combined. Rigorous cap rate analysis — verifying NOI against actual historical data, benchmarking market cap rates from true comparable sales, and stress-testing against cap rate expansion scenarios — is the foundation of disciplined commercial real estate underwriting.
