Net Operating Income definition and formula
Net operating income (NOI) is the most important profit measure in real estate. It strives to isolate to core operating profits of real estate assets, so as to avoid muddying the waters with non operating items such as corporate overhead and major non cash items like depreciation.
More important than what expenses factor into NOI are the expenses that don’t impact NOI. Namely, NOI captures profitability before any depreciation, interest, taxes, corporate level SG&A expenses, capital expenditures, or financing payments
Net operating income (NOI) example
Most real estate companies including REITs as well as real estate private equity firms – will own multiple real estate properties so identifying NOI is critical for isolating property-level profitability.
Below is a net operating income example from the Prologis 2019 10-K- one of the world’s largest REITs.
Interpreting net operating income (NOI)
From the Prologis 10-K , you can see that it is a non-gaap measure of profits so it does not appear on the income statement, but instead is presented in a separate table and is reconciled to GAAP metrics “operating income” and “earnings before income taxes.”
NOI vs EBITDA
NOI is similar to a common and nearly universally used measure of operating profitability EBITDA but with even more add backs to really focus on pure operating income generated by the properties.
