3,100 room-nights and 434,000 of revenue
The hotel has 100 rooms and the month has 31 days. That is the STR glossary’s supply example of 3,100 available room-nights. It sold 2,170 of them and collected 434,000 of room revenue. The revenue and the sold rooms are an example on that supply.
Room revenue: 25% lower
Change room revenue to 325,500 while keeping the other example values the same.
Room revenue: 25% higher
Change room revenue to 542,500 while keeping the other example values the same.

Quick answer
What does the Revenue per available room calculate?
How much room revenue does each available room earn? This calculator uses room revenue, rooms sold, and rooms available to estimate room revenue across every available room immediately in your browser.
With the values currently entered, the result is $140.00 — per available room. It also shows occupancy, average daily rate, and rooms available.
How to use the Revenue per available room
- Replace the example values with your own numbers.
- Review the result and supporting figures as they update automatically.
- Check the formula and assumptions before using the estimate for a decision.
Inputs used
- Room revenue
- Rooms sold — entered in rooms
- Rooms available — entered in rooms
Revenue per available room formula
RevPAR = room revenue ÷ rooms available. Occupancy = rooms sold ÷ rooms available. ADR = room revenue ÷ rooms sold.
Assumptions
- CoStar’s STR glossary defines RevPAR as room revenue divided by rooms available. Occupancy is rooms sold divided by rooms available. Average daily rate is room revenue divided by rooms sold. Rooms available is the room count times the days in the period. The glossary’s example is 100 rooms times 31 days, which is 3,100.
- Room revenue is guestroom rentals. The 434,000 and the 2,170 sold rooms are an example on that 3,100 supply. A room that is out of order is not available, so leave it out of the supply.

Practical guide
Revenue per available room example and edge cases
Revenue per available room divides room revenue by every room you could sell. CoStar’s STR glossary also writes it as occupancy times the average daily rate. Empty rooms lower RevPAR even when the sold-room rate stays high.
Example: 3,100 room-nights and 434,000 of revenue
The hotel has 100 rooms and the month has 31 days. That is the STR glossary’s supply example of 3,100 available room-nights. It sold 2,170 of them and collected 434,000 of room revenue. The revenue and the sold rooms are an example on that supply.

Calculated result$140.00per available room
434,000 divided by 3,100 is 140 per available room. Occupancy is 70 percent, because 2,170 divided by 3,100 is 0.70. The average daily rate is 200. Multiply 0.70 by 200 and you get the same 140.

How to read the result
- Read the 140 first. It is room revenue divided by the 3,100 available room-nights. Occupancy is 70 percent and the average daily rate is 200. Multiply those two and you get the same 140.
- STR’s 3,100 is 100 rooms times 31 days. A shorter month, or a room you take out of service, changes the supply. Change the available box when the month or the room count changes.
Edge cases worth checking
Out-of-order rooms are still in the supply
STR counts a room as available when you could sell it. An out-of-order room stays out of the supply. Leave it in and both occupancy and RevPAR fall.
Spa charges are inside room revenue
The glossary limits room revenue to guestroom rentals. A spa charge or a resort fee in the revenue box raises RevPAR for sales that were not a room night.
What changes the result most
Room revenue
Use a current amount for room revenue. Include fees or recurring costs that belong in the same figure.
Rooms sold
Measure rooms sold with the same unit shown beside the input. Convert first if your source uses another unit.
Rooms available
Measure rooms available with the same unit shown beside the input. Convert first if your source uses another unit.

Common mistakes
Check room revenue
CoStar’s STR glossary defines RevPAR as room revenue divided by rooms available. Occupancy is rooms sold divided by rooms available. Average daily rate is room revenue divided by rooms sold. Rooms available is the room count times the days in the period. The glossary’s example is 100 rooms times 31 days, which is 3,100. Make sure this matches the number you enter.
Keep rooms available consistent
Room revenue is guestroom rentals. The 434,000 and the 2,170 sold rooms are an example on that 3,100 supply. A room that is out of order is not available, so leave it out of the supply. Use the same units and time period throughout the calculation.
Do not rely on one revenue per available room scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
