Operating Expenses and Net Operating Income

When you subtract from adjusted gross income the expenses of running the property you are left with net operating income (NOI). For example:

Gross Income $1,440,000
Vacancy and Collection Loss (72,000)
Adjusted Gross Income $1,368,000
Operating Expenses (450,000)
Net Operating Income $918,000

Please note NOI is calculated before debt service. This is because, as a cost of capital, interest is not an operating expense incurred for the care and maintenance of the property.

Depreciation is a non-cash deduction that is used for income tax purposes, but is not deducted from adjusted gross income (AGI) to determine NOI. Again, depreciation, like interest, is not related to property operations.
