NOI = gross operating income − operating expenses

NOI generally focuses on property operations before owner financing, interest and income taxes. Keep definitions consistent.

Frequently asked questions
Are mortgage payments included in NOI?
Usually no. Debt service is generally analyzed after NOI.
Should inputs cover the same period?
Yes. When comparing income, expense, balance or price figures, keep the period and definitions consistent.
Is the result a final property valuation?
No. The calculator gives a numerical relationship only; real decisions also depend on location, market conditions, taxes, financing and risk.
