What Cap Rate Calculator does, with a checked example
Cap rate places a property's annual net operating income against its purchase price or current value, producing an unlevered income yield for a single period. This calculator handles the direct rate, the inverse value calculation, comparison with market rates, and a band of investment view based on debt and equity requirements. The common mistake is entering cash flow after mortgage payments as NOI. Debt service is financing, not a property operating expense, so including it understates NOI and the cap rate.
Worked example
A concrete input and expected output from the current implementation.
Input
Annual NOI: 60000; Property value: 800000
->
Expected output
Capitalization rate: 7.5%
60000 divided by 800000 equals 0.075. Expressed as a percentage, that is 7.5%; conversely, 60000 divided by 0.075 returns an indicated value of 800000.
