ADR Calculator – Average Daily Rate for Hotels (with occupancy & RevPAR)

Understanding the hotel ADR and RevPAR calculator — concept and principle

This calculator finds a hotel's average daily rate (ADR), occupancy rate and revenue per available room (RevPAR) from room revenue, room-nights sold, number of rooms and nights in the period. It also shows available and unsold room-nights and the revenue at full occupancy at the current ADR. Use it to track hotel or short-term rental performance and compare periods or properties.

ADR divides revenue by rooms sold; RevPAR divides it by all rooms available.

How it is calculated

Available room-nights = rooms × nights in the period.
ADR = room revenue ÷ room-nights sold.
Occupancy = room-nights sold ÷ available room-nights.
RevPAR = room revenue ÷ available room-nights = ADR × occupancy.
Revenue at full occupancy = ADR × available room-nights.

Leave out complimentary rooms and non-room income such as food or parking.

The principle

ADR measures pricing: the average price paid for each room actually sold. Occupancy measures demand: how many of the available rooms were sold. RevPAR combines the two by spreading room revenue over all available rooms, sold or not. A hotel can raise RevPAR by charging more or by filling more rooms, and RevPAR shows which trade-off works better. That is why hotels and hosts track all three metrics together.

Worked example

Default inputs: room revenue $62,400, 480 room-nights sold, 20 rooms, 30 nights.

Available room-nights = 20 × 30 = 600; unsold = 120.
ADR = 62,400 ÷ 480 = $130.00.
Occupancy = 480 ÷ 600 = 80%.
RevPAR = 62,400 ÷ 600 = $104.00 (= 130 × 0.80).
Revenue at full occupancy at this ADR = 130 × 600 = $78,000.

Each point is the calculator re-run with only “Room revenue for the period” changed; the gold point is the default example. Change the inputs above and this chart follows your numbers.

Room revenue for the period	ADR (average daily rate)
15,600	$32.50
31,200	$65.00
46,800	$97.50
62,400	$130.00
78,000	$162.50
93,600	$195.00
124,800	$260.00

How to read the result

Compare RevPAR with similar properties in the same market and season. A high ADR with low occupancy may mean prices are too high; high occupancy with a low ADR may mean prices could rise. Full-occupancy revenue is an upper bound that is rarely reached in practice.

Common mistakes

Including food, parking or resort fees in room revenue.
Counting complimentary rooms as sold, which lowers ADR.
Using the wrong number of available rooms when some are out of service.
Comparing RevPAR across very different markets or seasons.

Keep in mind: Industry reporting rules can differ in details. This is a performance calculation, not financial advice.

Frequently asked questions

What is the difference between ADR and RevPAR?

ADR is revenue per sold room; RevPAR is revenue per available room, including empty ones.

How do I calculate RevPAR from ADR?

Multiply ADR by the occupancy rate.

Is higher occupancy always better?

Not if it comes from cutting prices so much that RevPAR falls.
