Within the lodging industry, there are other metrics that have historically been reliable indicators to measure the potential for hotel profit growth. One is the change in rooms revenue, or RevPAR. Using data from our annual Trends® in the Hotel Industry, we find an 86 percent correlation between annual changes in RevPAR and Gross Operating Profit (GOP) from 1960 to 2016. This implies that changes in RevPAR do provide a very strong indication of changes in GOP.
