The formula to calculate the occupancy rate index (ORI) is:
\[ ORI = \frac{OCC}{C-OCC} \]
Where:
Let's say your hotel's occupancy percentage (OCC) is 75% and your competitor's occupancy percentage (C-OCC) is 60%. Using the formula:
\[ ORI = \frac{75}{60} \]
We get:
\[ ORI = 1.25 \]
So, the occupancy rate index is 1.25.
