The direct answer
Direct income capitalization divides a consistent stabilized annual NOI estimate by a selected cap rate expressed as a decimal. It turns one income assumption and one rate assumption into an indicated property value; it does not discover the correct market rate.
Reconcile stabilized income first
Review vacancy, lease income, operating responsibilities and the treatment of reserves. Stabilized NOI is an assumption about sustainable operations, not necessarily last year’s income. Identify the work or lease-up required to achieve it. Using gross revenue or after-debt cash flow in place of NOI changes the method and can create a materially different value.

Use a cap rate matching the income basis
A comparison rate is only useful when its NOI and property type are relevant to the subject. Different reserve conventions or a trailing-versus-forward income basis can distort the relationship. The model requires a positive rate and divides by the rate as a decimal. A lower rate produces a higher value for the same positive NOI, making rate sensitivity important.
Know when one annual income figure is too simple
Lease rollover, temporary income and major future capital spending may require a year-by-year analysis rather than a single stabilized subtotal. Direct capitalization does not model a debt amortization schedule, transaction costs or investor taxes. Treat the value as an indicated scenario and review the assumptions before using it for another calculation.
Worked example
At $120,000 stabilized NOI and a 6.5% cap-rate assumption, indicated value is $120,000 divided by 0.065, or $1,846,153.85. The reciprocal rate is 15.38 times annual NOI. At 7%, the same NOI would indicate about $1,714,285.71.

Common mistakes and limitations
Do not enter 6.5 as the decimal divisor outside a percent-input calculator; 6.5% is 0.065. Do not capitalize after-debt equity cash flow as though it were NOI.
Direct-capitalization estimate only. Cap rate selection and stabilized NOI require market judgment; not an appraisal.
Frequently asked questions
Does the tool identify the market cap rate?
No. The rate is a user-supplied assumption requiring relevant evidence.
Why is a zero cap rate rejected?
It is not a valid denominator for this direct-capitalization model.
