RevPAR (revenue per available room)
RevPAR, revenue per available room, is the room revenue a hotel earns for every room it had available, sold or not: room revenue divided by rooms available, which equals ADR multiplied by occupancy.
How to calculate RevPAR
RevPAR = room revenue ÷ rooms available = ADR × occupancy. An illustrative night: a 100-room hotel sells 80 rooms for €16,000 of room revenue. Its ADR is €200, its occupancy 80%, its RevPAR €160.
Use the same definition of rooms available in every period you compare, and the same definition of room revenue as for ADR.
What it leaves out
Because it counts the empty rooms, RevPAR is the figure hotels compare with their competitive set and the one owners ask about first. It still stops at the room: a guest who spends on dinner, the spa and a late check-out counts the same as one who only sleeps. TRevPAR covers that.
