NOI Calculator
Effective gross income minus operating expenses. Mortgage payments, income taxes, and depreciation are not part of this result.

- Effective gross income
- $200,000
Results use the numbers you enter. They are illustrative, not a loan quote, an appraisal, or a guarantee of investment performance.
Effective gross income is scheduled income plus other income, minus vacancy. NOI subtracts operating expenses from that figure.
Enter vacancy as a positive loss. The calculator rejects negative numbers so a minus sign is not counted twice. The article how to calculate NOI lists what belongs in expenses.
If NOI comes out below zero, the property’s expenses exceed the income you entered. That is a result. Take it to the pricing conversation instead of forcing a cap rate.
