How to calculate it
First establish GOP on a consistent accounting basis: total operating revenue less departmental operating expenses and undistributed operating expenses. Then divide by available room nights for the same period. Revenue and expenses must be recognised in matching periods, regardless of when cash was received or paid.
Keep expense classifications and availability rules stable. Financing costs, depreciation and income tax should not be confused with the operating expenses used to calculate GOP. Comparisons require a common currency and equivalent reporting framework. With zero available nights, GOPPAR is undefined. A negative GOP can produce a negative GOPPAR; the result should not be replaced with zero.
A hypothetical example
Over a 30-night month, 20 available rooms provide 600 available room nights. Operating revenue is €90,000, departmental expenses are €40,000 and undistributed operating expenses are €20,000. GOP is therefore €30,000 and GOPPAR is €50. This calculation describes the operating result before items that fall outside the definition of GOP.
What it tells you
The figure shows the operating profit generated relative to available capacity. If TRevPAR rises while GOPPAR falls, examine expense changes and the mix of services sold. The contrast does not identify the cause by itself; it points towards a closer review of the revenue and expense lines behind the totals.
When it is useful
It is useful for reviewing a season, comparing actual results with a budget and connecting operational and commercial discussions. It can also illuminate quieter months, when some expenses continue despite lower occupancy. Compare similar capacity or explain changes explicitly, rather than assuming every movement reflects improved or weaker operating performance.
It is not the owner’s final return
A GOPPAR of €50 does not mean the owner can withdraw €50 for every available night. Expenses and obligations remain outside GOP, and profit differs from cash flow. It is not automatically EBITDA per room either: the relevant accounting adjustments must be understood before treating those measures as interchangeable.
