This cap rate calculator divides annual net operating income by a property value you supply. Enter operating income and operating expenses for the same annual period, currency and property. The result shows the rate and its underlying NOI, including a negative rate when operating expenses exceed income. It does not retrieve market cap rates, recommend an investment or appraise a property. Keep purchase price, assessed value and independently supported market value distinct when selecting the denominator for your comparison.

Formula and methodology
Annual NOI = annual gross operating income − annual operating expenses. Cap rate % = 100 × annual NOI/property value.
The calculator applies the displayed arithmetic to the values entered on this device. It does not silently load a local tax rate, currency conversion or commercial assumption.
Worked calculation example
Annual income of 120,000 and operating expenses of 40,000 give NOI of 80,000. Against a supplied property value of 1,000,000, the capitalization rate is 8%.
How to interpret your result
The percentage reports annual property operating income relative to your chosen value basis. It is most useful when the NOI and value definitions are consistent across cases. The supporting annual and monthly-average NOI values make the basis visible, but do not add a forecast or valuation conclusion to the supplied inputs.

Scenario comparison
| Scenario | What it shows |
|---|---|
| 80,000 NOI on 1,000,000 value | 8%. |
| The same NOI on 2,000,000 value | 4%. |
| Income below expenses | negative NOI and cap rate remain visible. |
Common mistakes to avoid
- Mixing monthly income with annual expenses.
- Subtracting debt service inside property NOI.
- Comparing asking price and total project cost as identical denominators.
Reconcile NOI to the operating statement, then divide it by the selected property value. Doubling value while holding NOI constant should halve the rate. Multiplying both NOI and value by the same currency conversion factor should leave the rate unchanged. Verify the financial basis before using a ratio in any decision.
Authoritative reference. OCC explains direct capitalization using NOI and a capitalization rate. This worksheet performs the disclosed ratio and provides no appraisal or investment recommendation.What can affect the result?
Use a consistent annual operating basis
Income and expenses must cover the same period. Mixing monthly rent with annual expenses can reverse the meaning of the answer. Use actual, stabilized or projected figures consistently and state which basis you chose. This worksheet does not adjust vacancy, collection loss or future rent changes automatically. If the supplied gross-income figure has already been reduced for a particular loss, do not deduct that loss again. Keep a reconciliation from the underlying rental or operating statement to both input amounts.
Keep NOI separate from financing cash flow
Net operating income belongs to the property’s operations before the financing structure. Debt principal and interest are not automatically operating expenses for this cap-rate identity. Income taxes and depreciation also should not be mixed into an NOI expense figure merely because they appear in a broader accounting report. A lender or adviser may use a specifically adjusted NOI definition for a different purpose. Use the definition relevant to your intended analysis and disclose adjustments rather than relying on a broad label.
Choose and label the property-value denominator
A purchase price, appraisal, asking price and total project cost can differ. Each produces a different numerical rate for the same NOI. This page accepts your selected positive value without validating that it is a current market valuation. Do not compare properties using asking prices for some and completed acquisition costs for others without explaining the difference. Transaction expenses, renovation costs and anticipated capital expenditure need explicit treatment in the wider investment analysis; they are not silently embedded here.
Negative and zero results remain visible
If annual operating income equals expenses, NOI and the cap rate are zero. If expenses exceed income, the displayed NOI and rate are negative instead of being clipped to zero. That reports the supplied operating shortfall, not a bankruptcy diagnosis or a recommendation to sell. A zero property denominator is invalid because the rate is undefined. The worksheet does not forecast a turnaround, claim a target rate is safe or guarantee that the entered income can be collected.
Cap rate is one comparison, not total return
A direct capitalization ratio does not include leveraged cash-on-cash return, resale appreciation, future vacancy, irregular capital spending or a discounted cash-flow model. Two properties with the same cap rate can have very different risk and cash requirements. Use supporting operating records and appropriate professional analysis before a financial decision. The annual-average monthly NOI is simply annual NOI divided by twelve; it is not a forecast that every month will generate the same cash amount.
Privacy and browser processing
Values entered on this page are processed in the current browser session. SolvePilot does not require an account and does not receive the values entered into the calculator. Refreshing or closing the page clears the working values unless the browser itself restores a previous session. Avoid entering identifying or account information because the calculation needs summary values only.
Accuracy and verification
Accuracy depends first on input quality. Confirm definitions, scales, dates and source information before entering a value. Keep an independent record of any result used for planning because this page does not create an official statement or retain a calculation history.

Frequently asked questions
What is the cap-rate formula?＋
Divide annual NOI by the selected positive property value, then multiply by 100. The tool also displays the NOI calculation.
Is loan interest an operating expense here?＋
The intended NOI basis excludes debt service. Keep financing cash flow separate and verify any adjusted definition used by your adviser.
Can cap rate be negative?＋
Yes. When operating expenses exceed operating income, the supplied NOI and calculated rate are negative.
Does the calculator value my property?＋
No. You supply the property-value denominator. No appraisal or market-rate feed is included.
Is cap rate the same as investment return?＋
No. Financing, capital spending, resale, taxes and timing can change total investment outcomes beyond this ratio.
