NOI Calculator (Net Operating Income)
Build NOI line by line: gross rents, vacancy, other income and operating expenses — with the expense-ratio sanity check.
Formula
NOI deliberately excludes debt service, capex reserves and depreciation — it measures the property, not the financing. Multifamily expense ratios run 35–50% of EGI; a pro-forma showing 25% is hiding deferred maintenance or fantasy management costs.
Not financial advice — for informational and analytical use only. Verify all figures with a qualified professional before acting on them.
