The cap rate, or capitalization rate, is a compact way to compare income-producing real estate by relating annual net operating income to property value. It is most useful for screening commercial properties, estimating yield, and comparing similar assets in the same market. Because it uses operating income rather than financing costs, the cap rate is focused on the property itself, not on how an individual buyer funds the deal.
Use this calculator when you know the property’s annual NOI and current value. The result is expressed as a percentage: a higher cap rate generally implies more income relative to price, while a lower cap rate often indicates a higher-priced or lower-yield property. It should be interpreted alongside vacancy, operating risk, location, and capital expenditure needs.
How This Calculator Works
This calculator takes Net Operating Income (NOI) and property value as inputs and divides NOI by value to produce the cap rate. If the calculator shows a percentage output, it is the same ratio multiplied by 100. This gives a standardized yield measure that can be used to compare properties with different prices.
Formula
Cap Rate = NOI ÷ Property Value
Cap Rate (%) = (NOI ÷ Property Value) × 100
| Variable | Meaning | Units |
|---|---|---|
| NOI | Net operating income for one year after operating expenses | Currency per year |
| Property Value | Current market value or purchase price used for the analysis | Currency |
| Cap Rate | Annual unlevered yield of the property | Percent |
Important: NOI typically excludes debt service, income taxes, and depreciation. For best comparability, use the same valuation basis across all properties you compare.
Example Calculation
- Start with annual NOI of $120,000 and property value of $2,000,000.
- Divide NOI by value: 120,000 ÷ 2,000,000 = 0.06.
- Convert to a percentage: 0.06 × 100 = 6%.
- The cap rate is 6%.
Where This Calculator Is Commonly Used
- Commercial property acquisitions and underwriting
- Comparing office, retail, industrial, and multifamily assets
- Setting asking prices for income-producing properties
- Screening investment opportunities before deeper due diligence
- Checking whether a property’s income supports its current market value
How to Interpret the Results
A cap rate is a yield shorthand, not a complete risk model. A higher cap rate may signal more income relative to price, but it can also reflect higher vacancy, weaker location, greater operating risk, or deferred maintenance. A lower cap rate often suggests a lower-yield but potentially more stable or desirable property.
As a practical rule, compare cap rates only among similar property types, markets, and risk profiles. Also check whether NOI is stabilized or pro forma, whether reserves are included, and whether the value reflects a realistic market basis. Small assumptions can change the result materially.
Frequently Asked Questions
What is cap rate in real estate?
Cap rate, short for capitalization rate, is the annual net operating income of a property divided by its value. It is used to estimate the unlevered yield of an income-producing property and to compare one asset against another. It is especially common in commercial real estate.
What formula does this calculator use?
The calculator uses Cap Rate = NOI ÷ Property Value, then multiplies the ratio by 100 to display a percentage. NOI should represent annual operating income after operating expenses, but before financing costs and taxes. The property value should be the current market value or purchase price basis you want to analyze.
Is a higher cap rate always better?
Not necessarily. A higher cap rate means more income relative to price, but it can also indicate greater risk, weaker demand, or lower asset quality. A lower cap rate may reflect a premium property in a stronger market. Interpretation depends on context, not the number alone.
Should I use purchase price or appraised value?
Either can be used, but the choice should match your purpose. Purchase price is useful for deal analysis, while appraised or market value is better for comparing assets on a consistent basis. Be consistent across comparisons so the cap rate reflects differences in income, not differences in valuation method.
Does cap rate include mortgage payments?
No. Cap rate is an unlevered metric, so it does not include mortgage principal or interest payments. That makes it different from cash-on-cash return or debt service measures. If you want to evaluate financing impact, you need a separate loan-based calculation.
Can cap rate be negative?
Yes, if NOI is negative. That means operating expenses exceed operating income, which usually signals a distressed or transitional property. A negative cap rate is a warning sign and usually requires a careful review of expenses, vacancy, lease structure, and business plan assumptions.
