RevPAR or Revenue per Available Room is a key performance indicator (KPI) used by hotels and other leisure industry professionals to measure the average revenue a hotel earns for each available room. It is calculated by dividing the total room revenue by the number of available rooms.

RevPAR is an important metric in the hospitality industry as it provides insights into the hotel's pricing and occupancy levels. By monitoring and analyzing RevPAR, hotel managers can identify trends, benchmark against competitors, and make informed decisions regarding pricing and marketing strategies.

RevPAR can also help hotel managers to optimize their revenue streams, by forecasting demand and pricing their rooms accordingly. By monitoring RevPAR over time, they can adjust their pricing strategy to maximize their revenue during periods of high or low demand.

In short, RevPAR is a key metric used in revenue management, helping hotel managers to increase room revenue and profitability. It is a widely accepted metric used by the industry to evaluate hotel performance and make strategic decisions.
