Calculate capitalization rate, property value, or required NOI for any investment property
The capitalization rate — universally known as the cap rate — is the most fundamental metric in real estate investment analysis. It answers a simple but powerful question: what return does this property generate relative to its price? For anyone evaluating an income-producing property, whether a rental home, apartment complex, office building, or strip mall, the cap rate is the first number every investor, appraiser, and lender wants to know. Understanding cap rate is not just about plugging numbers into a formula. It is about decoding what a property is really worth in the context of its income stream, the local market, the property type, and the current interest rate environment. A 7% cap rate in Detroit signals something very different from a 7% cap rate in Manhattan. This calculator helps you not only compute the number but also interpret it with context. Our Cap Rate Calculator offers three calculation modes. In the most common mode, you enter the property value and net operating income to discover the cap rate. In the reverse mode, you enter a target cap rate and NOI to find what you should pay for the property — the implied property value. In the third mode, you enter a property price and your required cap rate to calculate the minimum NOI the property must generate to meet your return threshold. This three-way solver makes it equally useful whether you are a buyer evaluating a listing, a seller pricing a property, or an investor stress-testing a deal. Beyond the basic formula, this tool also supports a detailed income/expense breakdown mode. Instead of entering NOI directly, you can input the gross rental income, estimated vacancy rate, and total operating expenses. The calculator computes the effective gross income after vacancy and then subtracts expenses to derive NOI. This breakdown mode also generates a visual donut chart showing the split between effective income and expenses, giving you an immediate visual sense of the property's expense ratio. For serious investors, the sensitivity analysis table is one of the most valuable features. It shows how the cap rate changes as the purchase price moves ±10% and ±20% from the stated value. In negotiation scenarios, this lets you quickly answer the question: if I negotiate the price down by 10%, how does that improve my cap rate? The table makes price negotiations concrete and data-driven. The calculator also compares your property's cap rate to historical returns from alternative investments: the long-run S&P 500 average, intermediate Treasury bonds, and high-yield savings accounts. This comparison puts real estate returns in a broader financial context and helps investors decide whether the illiquidity and management burden of real estate is justified by the return premium over passive alternatives. For investors using financing, the optional cash-on-cash return section factors in your down payment and annual debt service to show the actual return on your invested cash — a metric that often differs significantly from the cap rate when leverage is involved. Finally, the property type reference table provides typical cap rate ranges for seven major asset classes: multi-family, single-family rental, office, retail, industrial, self-storage, and hotel. These benchmarks help you immediately identify whether a listing is priced at, above, or below the market norm for its property type.
Understanding Cap Rates
What Is a Cap Rate?
The capitalization rate (cap rate) is the ratio of a property's net operating income (NOI) to its current market value, expressed as a percentage. It represents the annual return an investor would earn if they purchased the property with all cash — no mortgage — and held it for one year. A property generating $40,000 in NOI and purchased for $500,000 has a cap rate of 8%. The cap rate is a snapshot metric: it reflects a single year's income relative to the current price, ignoring financing, future appreciation, and tax benefits. Despite these limitations, it remains the dominant shorthand metric for comparing income properties and evaluating market conditions across asset classes and geographies.
How Is Cap Rate Calculated?
Cap Rate = (NOI / Property Value) × 100. Net Operating Income is the annual income from the property after all operating expenses are deducted, but before mortgage payments and income taxes. Operating expenses typically include property taxes, insurance, property management fees, maintenance, repairs, utilities (if landlord-paid), and reserves for replacement. They do NOT include mortgage principal and interest, depreciation, or income taxes. In the breakdown mode, NOI is derived as: Effective Gross Income = Gross Rental Income × (1 − Vacancy Rate), then NOI = Effective Gross Income − Operating Expenses. The Gross Rent Multiplier (GRM) — another useful metric — is simply Property Price ÷ Annual Gross Rental Income.
Why Does Cap Rate Matter?
Cap rates serve three primary purposes for real estate investors. First, they let you quickly compare properties on an apples-to-apples income basis without worrying about different financing structures. Second, they serve as a reverse valuation tool: if you know the prevailing cap rate in a market for a given property type, you can estimate the property's value by dividing its NOI by that rate. Third, they reveal market sentiment: falling cap rates (meaning prices are rising faster than income) indicate a seller's market and compressed returns, while rising cap rates indicate either falling prices or improving fundamentals. Lenders, appraisers, and institutional investors use cap rates to benchmark transactions and underwrite loans.
Limitations of Cap Rate
Cap rate is a powerful but incomplete metric. It does not account for financing — a property with a great cap rate can still have negative cash flow if the mortgage rate is high. It uses a single year's income, ignoring growth potential, lease expirations, and deferred maintenance. It is purely backward-looking or point-in-time, not a measure of total return over a holding period. Cap rates vary significantly by market, property condition, lease structure, and tenant quality — two properties with identical cap rates can have very different risk profiles. Investors should use cap rate alongside other metrics such as cash-on-cash return, IRR, equity multiple, and debt service coverage ratio (DSCR) for comprehensive deal analysis.

Cap Rate Classification Guide
General thresholds for interpreting cap rates in the US market. Thresholds vary by property type and metropolitan area.
| Cap Rate Range | Classification | Typical Context |
|---|---|---|
| > 10% | High Yield | Secondary markets, value-add, distressed, or higher-risk properties |
| 8% – 10% | Au-dessus de la moyenne | Strong returns with moderate risk; common in growth metros |
| 6% – 8% | Moyen | Balanced risk/return; typical for well-leased stabilized properties |
| 4% – 6% | En dessous de la moyenne | Lower returns; prime locations, strong tenants, or gateway cities |
| < 4% | Low Yield | Trophy properties, gateway cities, or land-heavy deals |
Typical Cap Rates by Property Type (US National Average)
Approximate ranges as of 2024. Actual rates vary significantly by market, location, and property quality.
| Property Type | Cap Rate Range | Risk Profile |

Worked Examples
Example 1: Calculate Cap Rate for a Rental Property
You are considering buying a 4-unit apartment building listed at $600,000. The property generates $72,000 in annual gross rents. Vacancy is typically 5%, and operating expenses total $18,000 per year.
Effective Gross Income = $72,000 × (1 − 0.05) = $68,400
NOI = $68,400 − $18,000 = $50,400
Cap Rate = ($50,400 / $600,000) × 100 = 8.40%
The property has an 8.40% cap rate, which falls in the 'Above Average' range. If similar apartment buildings in this market trade at 7–8% cap rates, this property appears attractively priced.
Example 2: Reverse Calculation — How Much Should You Pay?
You require a minimum 7% cap rate on any investment. A property generates $45,000 in annual NOI. What is the maximum price you should pay?
Property Value = NOI / (Cap Rate / 100)
Property Value = $45,000 / (7 / 100)
Property Value = $45,000 / 0.07 = $642,857
You should pay no more than $642,857 for this property to achieve your 7% cap rate target. If the seller is asking $700,000, the cap rate would only be 6.43% — below your threshold.
Example 3: Cash-on-Cash Return with Financing
You buy a property for $500,000 with a $100,000 down payment (20%). The property has an NOI of $35,000. Your annual mortgage payment is $28,000.
Annual Cash Flow = NOI − Annual Debt Service = $35,000 − $28,000 = $7,000
Cash-on-Cash Return = ($7,000 / $100,000) × 100 = 7.0%
Cap Rate = ($35,000 / $500,000) × 100 = 7.0%
In this case, the cap rate and cash-on-cash return happen to be equal because the mortgage rate matches the cap rate. When mortgage rates are lower than the cap rate, leverage enhances cash-on-cash returns; when higher, leverage dilutes them.

Select one of three modes at the top: 'Find Cap Rate' computes the cap rate from property value and NOI; 'Find Property Value' shows what you should pay given a target cap rate and NOI; 'Find Required NOI' shows the minimum NOI needed at a given price to hit your target return.
Enter NOI Directly or Use Income Breakdown
Toggle between Direct NOI and Income Breakdown. In Direct mode, enter your annual net operating income. In Breakdown mode, enter gross rental income, vacancy rate, and operating expenses — the calculator derives NOI for you and shows a visual income-vs-expense donut chart.
Review Your Cap Rate and Analysis
The results show your cap rate with a classification (Low Yield to High Yield), a visual gauge, the sensitivity table showing how cap rate changes with price variations of ±10% and ±20%, and a comparison to alternative investments like the S&P 500 and Treasury bonds.
Add Financing for Cash-on-Cash Return
Expand the optional Financing Inputs section and enter your down payment and annual debt service (mortgage payments). The calculator will compute your annual cash flow and cash-on-cash return — the actual return on your invested equity after financing costs.
Questions Fréquemment Posées
What is a good cap rate for a rental property?
A 'good' cap rate depends heavily on your market and risk tolerance. In high-cost gateway cities like New York or San Francisco, cap rates of 3–5% are common because investors accept lower yields in exchange for stability and appreciation potential. In secondary and tertiary markets, 6–9% cap rates are typical. Cap rates above 10% often signal higher risk — either a distressed property, a declining market, or significant deferred maintenance. As a general rule, compare your cap rate to other recent sales of similar properties in the same submarket rather than relying on a universal threshold.
What is the difference between cap rate and cash-on-cash return?
Cap rate measures income return relative to total property value, assuming an all-cash purchase. Cash-on-cash return measures the annual cash flow (after debt service) relative to your actual cash invested. If you finance a purchase with a mortgage, your cash-on-cash return will differ from the cap rate. For example, if a property has a 7% cap rate but your mortgage rate is 6.5%, your leverage is thin and cash-on-cash return may be much lower — or even negative — after debt service. Cash-on-cash return is generally more relevant for leveraged investors, while cap rate is more useful for property valuation and market comparison.
Does cap rate include mortgage payments?
No. The cap rate formula is based on Net Operating Income (NOI), which is calculated before mortgage payments (debt service). NOI includes all revenue minus operating expenses such as property taxes, insurance, management fees, maintenance, and utilities — but explicitly excludes financing costs. This is by design: removing financing makes cap rates comparable across buyers with different loan terms. If you want to account for financing, use cash-on-cash return or the Debt Service Coverage Ratio (DSCR) instead. This calculator's optional financing section lets you compute cash-on-cash return separately.
What is the relationship between cap rate and property value?
Cap rate and property value have an inverse relationship. When cap rates fall, property values rise (assuming NOI is constant), and vice versa. This is because Value = NOI ÷ Cap Rate. If market cap rates compress from 6% to 5% due to increased investor demand, a property generating $60,000 in NOI would be valued at $1,200,000 instead of $1,000,000 — a 20% increase in value with no change in income. This dynamic is why real estate investors pay close attention to interest rate movements: rising rates typically push cap rates up, reducing property values.
What expenses are included in NOI?
Net Operating Income includes all operating expenses necessary to maintain and manage the property: property taxes, property insurance, property management fees (typically 8–12% of gross rents), routine maintenance and repairs, landscaping, cleaning, utilities paid by the landlord, pest control, and a reserve for capital expenditures. NOI explicitly excludes mortgage principal and interest, depreciation, income taxes, and major capital improvements (though some analysts include replacement reserves). Using accurate, market-rate expense estimates is critical — understating expenses inflates NOI and makes the cap rate look better than it actually is.
What is the Gross Rent Multiplier (GRM) and how does it relate to cap rate?
The Gross Rent Multiplier (GRM) is a simpler valuation metric calculated as Property Price ÷ Annual Gross Rental Income. While the cap rate uses NOI (after expenses), the GRM uses gross income before expenses, making it quicker to calculate but less precise. A GRM of 12 means the property costs 12 times its annual gross rent. GRM is most useful for quick screening comparisons, especially when expense data is unavailable. The cap rate is superior for detailed analysis because it accounts for the actual expense burden of the property. This calculator shows both metrics when you use the income breakdown mode.
