Hotel KPIs Explained: Occupancy, ADR, RevPAR and What to Watch

Three numbers describe most of a hotel’s health — occupancy, ADR and RevPAR. Here is what each one actually measures, how they mislead when read alone, and the handful of second-tier KPIs worth adding.

Hotel metrics have a vocabulary problem: the abbreviations sound interchangeable, and every dashboard shows a dozen of them. In practice, a small property can steer with three primary numbers and four or five supporting ones — as long as everyone agrees on what they mean and they come from one closed, consistent day (that is the night audit’s job).

In short

  • Occupancy measures volume, ADR measures price, RevPAR combines both — read them together, never alone.
  • RevPAR = occupancy × ADR. It is the single best one-line summary of room revenue performance.
  • Add GOPPAR or TRevPAR once rooms-only numbers stop telling the whole story.

The big three

Occupancy — the share of available rooms you sold.

Occupancy = rooms sold ÷ rooms available. A 12-room hotel that sells 10 rooms tonight runs at 83% occupancy. High occupancy feels like success, but on its own it says nothing about price — you can fill every room by undercharging for all of them.

ADR (average daily rate) — the average price of the rooms you did sell.

ADR = room revenue ÷ rooms sold. If those 10 rooms brought in $2,900, ADR is $290. ADR alone has the opposite blind spot: a spectacular rate on a nearly empty house is still a bad night.

RevPAR (revenue per available room) — what every room, sold or not, earned.

RevPAR = room revenue ÷ rooms available, or equivalently occupancy × ADR. Our example hotel: $2,900 ÷ 12 = $241.67. RevPAR is the number to trend over time, because it punishes both empty rooms and underpricing. When you experiment with rates (see revenue management for small hotels), RevPAR is the scoreboard.

Read them as a triangle: occupancy up while ADR collapses means you bought volume with price. ADR up while occupancy collapses means you priced yourself empty. RevPAR tells you whether the trade was worth it.

Beyond the big three

Which number to watch when

Getting the numbers without the spreadsheet

Every KPI here is arithmetic on data your systems already hold. The only hard part is getting rooms, restaurant and finance to agree on the inputs — which is a systems problem, not a math problem. If assembling last month’s RevPAR takes an afternoon of exports, the fix is not a better spreadsheet; it is software that shares one data model.

Your KPIs, live — not in a spreadsheet

HotelBi tracks occupancy, ADR and RevPAR in real time across rooms, restaurant and finance — one source of truth.
