The formula
Occupancy = room-nights sold ÷ room-nights available × 100, where room-nights available = rooms × nights in the period. A 40-room hotel over a 30-night month has 1,200 available room-nights; selling 880 of them is 73.3% occupancy.
Reading occupancy correctly
High occupancy is not automatically good news: if you fill the house at deeply discounted rates, RevPAR — occupancy × ADR — can be lower than running 70% at a healthy rate, with more cleaning and breakfast costs on top. Occupancy answers "how full"; pair it with ADR and RevPAR to answer "how profitably full".
FAQ
How do I calculate hotel occupancy percentage?
Occupancy % = room-nights sold ÷ room-nights available × 100. Room-nights available = number of rooms × nights in the period. Example: 40 rooms × 30 nights = 1,200 available; selling 880 is 73.3% occupancy.
What is a hotel room night calculator?
A room-night (or hotel night) is one room sold for one night. Counting room-nights — not just "rooms" — is how you measure occupancy and revenue across multi-night stays and multi-room hotels. This calculator works in room-nights so monthly and weekly reports stay comparable.
Do out-of-order rooms count as available?
Convention varies: most operators keep short-term out-of-order rooms in the denominator and only remove rooms taken offline long-term (renovations). Pick one convention and keep it consistent so trends stay meaningful.
