### By selecting a comparison period in the Comparison Period Selection Control, the data comparison function in the Statistics module is activated. It allows you to see how the condition of your business has changed compared to the past.

Each of the Statistics modules has algorithms that calculate the percentage change in the base period data relative to the comparison period data.

The percentage change for each module is calculated in a similar way:

- Total income module

If your income in the base period was €6,000 and in the comparison period was €4,000, Statistics will show a 50% increase in income.

- Occupancy module

If your occupancy was 50% in the base period and 40% in the comparison period, Statistics will show an increase in occupancy of 25%.

- Revenue and occupancy module

If the income at a given chart point in the base period is €200 and occupancy is 70%, and in the comparison period the same chart point has an income of €600 and occupancy of 90%, Statistics will show a decrease in income of 67% and occupancy of 22%.

- Additional data module
**- Number of bookings**

If the number of bookings of the base period was 20, and in the comparison period was 15, the Statistics will show an increase in the number of bookings by 33%.**- Booking Window**

If the Booking Window of the base period was 15 days, and in the comparison period was 20 days, the Statistics will show a decrease in Booking Window by 25%.**- Number of cancellations**

If the number of cancellations in the base period was 2, and in the comparison period was 6, the Statistics will show a decrease in the number of cancellations by 67%.**- RevPAR**
