Direct answer
Hotel occupancy measures sold or occupied room-nights against defined available inventory; ADR measures room revenue per room sold; RevPAR measures room revenue per available room. The three reconcile only when inventory, period, revenue, and room-status definitions match.
What this calculation tells you
A room-inventory reconciliation constructs the denominator before calculating performance. It starts with physical rooms, removes entered out-of-order inventory under the chosen reporting convention, and checks paid and complimentary occupied room-nights against availability.
Once the inventory is sound, ADR and RevPAR help distinguish price and volume. A hotel can raise ADR while losing occupancy, or fill more rooms at a lower rate; RevPAR combines both effects but still says nothing directly about acquisition cost, departmental expense, or profit.
Where it is used
Hotel operations
Reconcile daily, weekly, or monthly room inventory and paid occupancy.
Revenue management
Separate rate, occupancy, and availability effects before comparing periods.
Asset management
Connect top-line room performance with later profit and cost analysis.
Benchmarking
Check that subject and comparison data use compatible definitions and periods.
Common situations
- Rooms are out of order for part or all of a reporting period.
- Complimentary and house-use rooms are mixed with paid rooms sold.
- ADR rises while total room revenue or RevPAR falls.
- Gross room revenue differs materially from net revenue after channel costs.
Reconcile room supply before dividing
Define the reporting period, physical room count, out-of-order treatment, and available room-nights. The primary calculator treats the entered out-of-order count as unavailable throughout the entered period. If availability changes during the period, split the record into internally consistent subperiods, calculate each separately, and reconcile their room-nights before interpreting the combined result.
Check that paid rooms sold, complimentary rooms, house use, day use, no-shows, and other statuses follow the property’s reporting standard. The arithmetic should reject occupied room-nights above availability, but classification remains an operational judgment.
Keep revenue and room denominators aligned
ADR divides the relevant room revenue by paid rooms sold. RevPAR divides relevant room revenue by available room-nights. Using total hotel revenue, including food, spa, or parking, in the numerator creates a different metric such as TRevPAR when defined consistently.
Taxes, resort fees, packages, rebates, commissions, and transaction fees need one documented accounting treatment. Gross and net ADR can both be useful, but they must be labeled and should not be compared as if identical.
Interpret the rate–occupancy trade-off
RevPAR can be reconciled as ADR multiplied by occupancy when definitions align. That identity is a quality-control check, not an explanation of why performance changed.
Compare mix, channel, length of stay, day of week, season, group displacement, cancellations, and available inventory before attributing movement to a pricing decision. Competitive-set indexes also depend on the quality and relevance of the comparison set.
Move from room revenue to profitability carefully
Higher RevPAR can coexist with weaker profit if distribution, labor, utilities, amenities, or other costs rise. Net RevPAR, departmental profit, GOPPAR, and flow-through answer later questions and use different numerators.
Do not use a generic threshold to declare a hotel healthy, efficient, or investable.
- Do not divide by physical room count when availability differs.
- Do not mix paid and complimentary rooms silently.
- Do not call ADR a measure of all guest revenue.
- Do not infer profit or demand causation from RevPAR alone.
Practical questions
Frequently asked questions
Can RevPAR be calculated as ADR multiplied by occupancy?
Yes when ADR, occupancy, room revenue, rooms sold, availability, and period definitions align. The direct room-revenue-over-available-rooms calculation is a useful reconciliation.
Should complimentary rooms count as occupied?
Follow the property’s reporting standard and label the treatment. Keep paid occupancy and total occupied use separately visible when that distinction matters.
Why can ADR rise while RevPAR falls?
Because the average paid rate can increase while occupancy falls enough to reduce room revenue per available room.
