GOP and NOI sit next to each other on every hotel P&L and they are used interchangeably by people who do not own the property. They are not the same number, and the gap between them is the line where the operator's job ends and the owner's job begins.
GOP defined
Gross Operating Profit = Total Revenue − Departmental Expenses − Undistributed Operating Expenses. It excludes: management fees, FF&E reserve, property tax, insurance, rent, depreciation, amortization, interest.
GOP is what the property earned from operating, before the cost of owning it and before any fees paid to the brand or management company. A 240-key resort with €18M total revenue and a 32% GOP margin produces €5.76M of GOP.
NOI defined
Net Operating Income = GOP − Management Fee − FF&E Reserve − Property Tax − Insurance − Ground Rent (if any). It excludes: depreciation, amortization, interest, income tax.
Same €5.76M GOP property: subtract 3% management fee on revenue (€540k), 4% FF&E reserve on revenue (€720k), property tax (€280k), insurance (€140k), no ground rent. NOI = €4.08M. The €5.76M GOP became €4.08M NOI — a 29% gap.
Why the gap matters
The owner buys the property based on NOI multiples (typically 12-18× NOI depending on market and asset quality). The operator is bonused on GOP. The two are looking at different denominators in the same income stream. If the operator pushes a strategy that lifts GOP by €100k while incurring €120k of additional FF&E reserve or property tax exposure, GOP looks great and NOI is worse. The owner notices.
How to talk about both
A good operator runs the GOP analysis for tactical decisions and runs the GOP-to-NOI bridge once a quarter for ownership conversations. The quarterly bridge is a single page: GOP, then each subtractor with its variance to budget, then NOI. Five minutes of work that buys credibility for years.
