How the nights are counted
Divide room nights sold by available room nights and multiply by 100. Both counts must cover the same dates and units. When capacity changes during a period, add the available rooms night by night rather than using a single fixed room count.
Check how the report treats closures, owner use and blocked dates. A blocked night is not automatically a sale. Different reports can use different definitions of available inventory, so align their bases before comparing them. Occupancy is undefined with zero available room nights; it is 0% when nights are available but none are sold.
A hypothetical example
Ten rooms available for 30 nights produce 300 available room nights. Selling 210 gives 70% occupancy. A family of four staying in one apartment for three nights contributes three sold unit nights, not twelve. Twelve would be guest nights, which measure a different kind of activity.

What the result tells you
Occupancy helps identify dates with gaps and periods with a heavier operational workload. It supports planning, but arrivals, departures and length of stay add essential context. The same occupancy can involve very different numbers of room turnovers and therefore different housekeeping requirements.
For commercial decisions, read it alongside ADR and RevPAR. Selling more nights is one part of performance; the rates achieved and the expenses associated with those stays also matter to the business.
When occupancy is useful
Review occupancy by date or unit type when planning operations and examining upcoming gaps. For historical comparisons, check whether available inventory changed. The same percentage can represent a different number of room nights sold after a refurbishment or the addition of rooms.
A full calendar is not the whole story
Filled calendar cells may represent reservations, maintenance or personal use. Commercial occupancy cannot be inferred simply from how many dates look blocked. Nor does 100% occupancy prove maximum profit: low rates or high expenses can limit the final result despite every room night having been sold.
