    This result reflects your annual NOI and property value inputs. Compare it with actual transactions involving similar property, leases, condition, and location. The percentage alone does not establish investment quality or lender acceptance.

    What Is a Commercial Real Estate Cap Rate?

    The capitalization rate is annual net operating income divided by property value, expressed as a percentage. Your NOI excludes mortgage payments. This calculator measures the relationship between the two inputs you provide. A low result does not prove the building is safe, and a high result does not establish that the income will continue. Check the tenant leases, expenses, condition, and comparable transactions before drawing a conclusion. Read how to value commercial property to review the methods behind an estimate.

    Cap Rate Formula and Calculation

    To calculate cap rate, divide net operating income by property value, then express the result as a percentage. NOI is annual rental income minus operating expenses, before mortgage payments. This cap rate formula applies whether you are evaluating a commercial building, multifamily property, or another income producing real estate asset.

    Cap Rate = (NOI / Property Value) × 100

    You can rearrange the formula to solve for property value when you know the market cap rate. Divide NOI by the cap rate to get an estimated value. This calculator does not run that reverse cap rate calculation; use our property value calculator for that estimate.

    How to Calculate Cap Rate: Worked Example

    For an arithmetic illustration only, consider a hypothetical multifamily building with $120,000 per year in gross rent. Applying an assumed 5 percent vacancy gives effective gross income of $114,000. Assumed annual operating expenses total $41,120, leaving NOI of $72,880. These are example inputs, not a closed CapitalAx transaction or current market benchmarks.

    At an illustrative property price of $1,040,000, the cap rate calculation is:

    NOI = $114,000 - $41,120 = $72,880
    Cap Rate = ($72,880 / $1,040,000) × 100 = 7.0%

    The result describes the relationship between these example income and price assumptions. It does not establish a market cap rate or show whether the property is fairly priced. Compare verified transactions with similar locations, leases, condition and income quality before choosing a rate for a valuation.

    What Is a Good Cap Rate?

    There is no single good cap rate for every property. Compare the asset with relevant transactions and consider location, lease duration, tenant credit, vacancy, deferred work and how the NOI was calculated. A higher cap rate can reflect greater risk or income assumptions that need closer review; it does not automatically make the investment better.

    Cap Rate vs. Cash on Cash Return

    Cap rate treats the property as if it were purchased for all cash. It ignores financing entirely, which makes it useful for comparing properties independent of how they are funded. Cash on cash return measures the income you receive relative to the cash you actually invested after taking out a loan. Use cap rate to screen deals and cash on cash to evaluate your leveraged returns. Our return calculator covers both.

    From Cap Rate to a Financing Decision

    Cap rate excludes mortgage payments, so it cannot tell you whether the property's income supports a proposed loan. Use the commercial loan payment and amortization calculator to estimate debt service, then the DSCR calculator to compare that obligation with NOI. Loan proceeds still depend on lender underwriting, value, property condition and the borrower.

    For an apartment building, review how much your apartment building is worth before applying a comparable cap rate. For a retail center, review shopping center financing, where tenant leases and vacancies can change the income used in this calculation.

    Frequently Asked Questions

    The capitalization rate is the ratio of a property's annual net operating income to its market value, shown as a percentage. Investors use it to compare commercial real estate opportunities and gauge the return a property produces relative to its price.

    Divide annual net operating income by the property value, then multiply by 100. For example, a property with $200,000 in NOI and a $2,500,000 value has an 8 percent cap rate. The calculator above does this for you.

    Yes. Cap rate and capitalization rate mean the same thing in real estate. This capitalization rate calculator uses annual NOI and property value to calculate the implied rate for a commercial property, multifamily property, or rental property.

    Yes. Enter the commercial property's annual NOI and current or proposed value. The result helps compare the property's unleveraged income return with other commercial real estate opportunities. It is not a formal appraisal or a guarantee of market value.

    Yes. This commercial real estate cap rate calculator uses annual NOI and property value to estimate the property's unleveraged capitalization rate. This commercial cap rate calculator is useful for comparing commercial properties, but it does not replace lender underwriting or an appraisal.

    Yes. Enter a multifamily property's annual NOI after operating expenses and its current or proposed value. The result can help compare an apartment property's unleveraged income return with other opportunities. It does not account for the mortgage, financing costs, or a specific investor's cash on cash return.

    No. A cap rate calculator with mortgage debt would measure a different return because cap rate intentionally ignores financing. Use cap rate to compare the property itself. Use cash on cash return to evaluate how a specific loan and down payment affect your invested cash.

    No. This calculator calculates cap rate from NOI and property value. To estimate property value from NOI and a selected market cap rate, use the CapitalAx property value calculator. That estimate is not a formal appraisal.

    No. An interest rate cap is a financial contract that limits the interest rate on certain floating rate loans. This tool calculates a real estate capitalization rate from NOI and property value, not an interest rate cap.

    There is no single good cap rate for every commercial property. Compare relevant transactions and review location, leases, tenant credit, vacancy, condition and the quality of NOI. A higher cap rate can reflect greater risk rather than a better investment. This calculator does not supply current local market cap rates.

    Not always. A higher cap rate usually signals higher risk, such as a weaker location, deferred maintenance, or vacancy. A lower cap rate reflects a safer, more in demand property. The right cap rate balances return against the risk you are willing to take.

    Cap rate measures return based on the full property value and ignores financing. Cash on cash return measures the cash income you earn relative to the actual cash you invested, so it accounts for your loan and down payment.
