What Is a Commercial Real Estate Cap Rate?
The capitalization rate, or cap rate, is the ratio of a property's annual net operating income to its market value. This capitalization rate calculator is useful for commercial real estate because it lets investors compare commercial property, multifamily, and rental opportunities on a consistent basis regardless of financing. A lower cap rate generally reflects a safer, higher-priced property, while a higher cap rate suggests more risk alongside potentially higher returns.
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
A six-unit multifamily building generates $120,000 per year in gross rent. Vacancy runs 5 percent, so effective gross income is $114,000. Annual operating expenses (property taxes, insurance, maintenance, and management at 8 percent of collected rent) total $41,120. That leaves an NOI of $72,880.
The property sold for $1,040,000. Plugging those numbers into the cap rate formula:
NOI = $114,000 - $41,120 = $72,880
Cap Rate = ($72,880 / $1,040,000) × 100 = 7.0%
A 7.0 percent cap rate sits in the value-add range for most markets. Compare that figure to recent comparable sales in the area to judge whether the price reflects fair market value.
What Is a Good Cap Rate?
There is no single right number. Stabilized properties in strong markets often trade between 4 and 7 percent. Value-add deals and properties in secondary markets can run 7 to 10 percent or more. The right cap rate is the one that matches your return target and the level of risk you are willing to take.
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.
Frequently Asked Questions
What is a cap rate?
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.
How do you calculate cap rate?
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.
Is this a capitalization rate calculator for real estate?
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.
Can I use this as a commercial property cap rate calculator?
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.
Can I use this as a commercial real estate cap rate calculator?
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.
Can I use this as a multifamily cap rate calculator?
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.
Does this cap rate calculator include a mortgage?
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.
Can this calculator run a reverse cap rate calculation?
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.
Is this an interest rate cap calculator?
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.
What is a good cap rate for commercial real estate?
It depends on the property type, location, and risk. Stabilized properties in strong markets often trade between 4 and 7 percent, while value add deals and secondary markets can run 7 to 10 percent or higher. A good cap rate is one that fits your return target and risk tolerance.
Does a higher cap rate mean a better investment?
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.
What is the difference between cap rate and cash on cash return?
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.
