Free RevPAR Calculator for Hotels

RevPAR stands for revenue per available room. STR (CoStar) defines it as "total room revenue divided by the total number of available rooms." It tells you how much room revenue you earned for each room available in the period, whether that room was sold or not.

The formula is RevPAR = Room revenue ÷ Rooms available. Because ADR = Room revenue ÷ Rooms sold and Occupancy = Rooms sold ÷ Rooms available, pure algebra gives a second form: RevPAR = ADR × Occupancy. The calculator handles both paths.

RevPAR matters because it combines pricing and occupancy into one number. A high ADR means little if rooms sit empty, and full occupancy at a steep discount can still leave room revenue low. For a detailed walkthrough of the methodology, see the full RevPAR calculation guide.

1. Choose a currency (EUR, USD or GBP) from the select at the top. This changes only the symbol shown in the result.
2. Pick a tab. From room revenue (the default): enter Room revenue, Rooms in the hotel and Days in the period. The calculator multiplies rooms by days to get rooms available. If you already know your rooms available figure, click "Enter rooms available directly" to replace those two fields with one. From ADR and occupancy: enter ADR and Occupancy (%).
3. Fill in the optional fields if you have the data. Rooms sold adds occupancy, ADR and a check line to the result. Competitive set RevPAR adds your RevPAR Index (RGI).
4. Read the result next to the form (below it on a phone). Numbers update as you type once every required field is valid. Press "Calculate" to highlight missing or invalid fields, "Try an example" to load sample data, or "Clear" to reset everything.

You can type numbers with or without thousands separators and with either a decimal point or a decimal comma.

The result always shows RevPAR with the formula written out using your numbers, so you can trace the arithmetic. If you entered rooms sold, the result also shows occupancy and ADR, followed by a check line (ADR × Occupancy = RevPAR) that lets you verify the two calculation paths agree.

If you filled in a competitive set RevPAR, the calculator shows your RevPAR Index (RGI). STR defines this index so that 100 means you capture exactly your expected share of the group's performance. Above 100 means you outperform the set; below 100 means you trail it. The further the index moves from 100, the larger the gap.

To judge your own RevPAR over time, compare the same period year over year, track month-by-month changes, and measure against your budget. The index adds a competitive layer: if your RevPAR rises but your index falls, the competitive set grew faster than you did in the same period.

• Mixing room revenue with total revenue: RevPAR uses only room revenue. If you include food, spa or parking income, you are calculating TRevPAR, not RevPAR.
• Wrong period for rooms available: rooms available is the number of rooms in the hotel multiplied by the days in the period. Using the wrong day count skews every metric that depends on it.
• Counting complimentary rooms as sold: STR's definition of rooms sold excludes complimentary rooms. Counting them raises occupancy and lowers ADR, while RevPAR from room revenue ÷ rooms available does not change.
• Ignoring the competitive set: your RevPAR may rise while your market share falls. The RevPAR Index shows whether your gain is faster or slower than the group around you.
• Inconsistent treatment of adjustments: STR's Data Reporting Guidelines cover what to include or exclude from room revenue. If you compare with STR data, follow those guidelines; otherwise choose one convention and apply it every period.

RevPAR, ADR and occupancy are linked by the identity RevPAR = ADR × Occupancy. Any two of the three determine the third. The ADR calculator focuses on average rate, and the occupancy rate calculator isolates the fill rate.

When choosing which metric to act on, consider what you can change. ADR reflects pricing power; occupancy reflects demand capture; RevPAR shows the combined effect. Tracking all three shows which one moved, and the RGI compares your RevPAR with the competitive set.

If you need a broader view that includes food and beverage, spa and other operating revenue, use TRevPAR (total revenue per available room) instead. TRevPAR divides total revenue by rooms available rather than room revenue alone.
