FO Formula – Hotel Occupancy Percentage | Occupancy Ratio Calculation 

The FO Formula, also known as the Front Office Formula, is a simple calculation used in the hotel industry to determine the occupancy percentage of a hotel. This formula takes into account the number of rooms sold and the total number of rooms available in the hotel. By using this formula, hotel managers can determine the occupancy rate of their hotel, which is an important metric for measuring the success of their business.

To calculate the hotel occupancy percentage using the FO Formula, simply divide the number of rooms sold by the total number of rooms available, and then multiply the result by 100. For example, if a hotel has 100 rooms and 80 of them were sold on a particular night, the occupancy percentage would be calculated as follows:

Occupancy Percentage = (80 / 100) x 100 = 80%

This means that on that particular night, the hotel was 80% occupied. The FO Formula can be used on a daily, weekly, or monthly basis to track the occupancy rate of a hotel and to make informed decisions about pricing, staffing, and other important aspects of hotel management.

Overall, the FO Formula is a valuable tool for hotel managers who want to keep track of their occupancy rates and make data-driven decisions to improve their business.

Occupancy Percentage is the most commonly used operating ratio in the hotel front office, The Occupancy percentage indicates the proportion of rooms either sold or occupied to the number of rooms available for the selected date or period.

The Formula for Occupancy Percentage:

Occupancy Percentage= (Number of Rooms Occupied) / (Total Number of Rooms Available for sale) * 100

There are generally two ways used to calculate the occupancy percentage in the hotel, one by the number of Rooms Occupied and another by the Rooms Sold (Rooms Sold = Occupied rooms – Complimentary and House use)

Also at some hotel Available Rooms are taken after reducing the OOO (Out of Order Rooms) ie Sellable Rooms = Available Rooms – Out Of Order Rooms. Other hotels always take all rooms in their hotel as Available Rooms because this gives a consistent base on which the occupancy is measured. 

1) Example Occupancy Percentage Calculation (Based on Rooms Occupied)

Total Number of Rooms Available in the hotel             = 215

Number of Rooms Occupied on 10th September 2017 = 207

Hotel’s Occupancy Percentage = 207 / 215 *100

                                            = 96.28 %

2) Example Occupancy Percentage Calculation (Based on Rooms Sold)

Total Number of Rooms Available in the hotel             = 215

Number of Rooms Occupied on 10th September 2017 = 207

Total House Use and Complimentary Rooms = 2                 

Hotel’s Occupancy Percentage = (207 – 2) / 215  *100

                                          = 95.34 %

3) Example Occupancy Percentage Calculation (Based on Available Rooms)

Total Number of Rooms in the hotel                          = 215

Number of Rooms Occupied on 10th September 2017 = 207

Hotel’s Occupancy Percentage = 207 / 215 *100

                                            = 96.28 %

4) Example Occupancy Percentage Calculation (Based on Sellable Rooms)

Total Number of Rooms Available in the hotel             = 215

Number of Rooms Occupied on 10th September 2017 = 207

Total Out of Order (OOO) Rooms = 5                 

Hotel’s Occupancy Percentage = 207 / (215 – 5)  *100

                                            = 98.57 %
