The Occupancy Rate is a key performance indicator (KPI) for hotels, measuring the utilization of available rooms over a specific period. It's calculated by dividing the number of rooms sold by the total number of rooms available and multiplying by 100 to express it as a percentage.
A high occupancy rate generally indicates strong demand and effective sales and marketing strategies. However, it's crucial to balance occupancy with Average Daily Rate (ADR) to maximize revenue.
Formula:
Actual Occupancy Rate (%) = (Number of Occupied Rooms / Total Number of Rooms) * 100
This calculator helps you determine your current occupancy rate and also shows how many additional rooms would need to be occupied to reach a specific target occupancy percentage.
Example:
Let's say a hotel has 150 rooms in total. On a particular night, 120 rooms are occupied. The hotel's target occupancy rate is 80%.
To reach a target of 80%, the hotel would need 120 occupied rooms (150 * 0.80). In this case, they are already at their target. If their target was 85%, they would need (150 * 0.85) = 127.5, meaning they would need 128 occupied rooms, so 8 more rooms than currently occupied.
function calculateOccupancyRate() {
var totalRooms = parseFloat(document.getElementById("totalRooms").value);
var occupiedRooms = parseFloat(document.getElementById("occupiedRooms").value);
var targetOccupancyPercentage = parseFloat(document.getElementById("occupancyPercentage").value);
var actualOccupancyResultElement = document.getElementById("actualOccupancy");
var roomsNeededForTargetResultElement = document.getElementById("roomsNeededForTarget");
actualOccupancyResultElement.innerText = "";
roomsNeededForTargetResultElement.innerText = "";
if (isNaN(totalRooms) || isNaN(occupiedRooms) || isNaN(targetOccupancyPercentage)) {
actualOccupancyResultElement.innerText = "Please enter valid numbers for all fields.";
return;
}
if (totalRooms <= 0) {
actualOccupancyResultElement.innerText = "Total number of rooms must be greater than zero.";
return;
}
if (occupiedRooms totalRooms) {
actualOccupancyResultElement.innerText = "Number of occupied rooms must be between 0 and the total number of rooms.";
return;
}
if (targetOccupancyPercentage 100) {
actualOccupancyResultElement.innerText = "Target occupancy percentage must be between 0 and 100.";
return;
}
// Calculate Actual Occupancy Rate
var actualOccupancyRate = (occupiedRooms / totalRooms) * 100;
actualOccupancyResultElement.innerText = "Actual Occupancy Rate: " + actualOccupancyRate.toFixed(2) + "%";
// Calculate Rooms Needed for Target Occupancy
var targetOccupancyDecimal = targetOccupancyPercentage / 100;
var roomsNeededForTarget = Math.ceil(totalRooms * targetOccupancyDecimal); // Use Math.ceil for whole rooms
var roomsDifference = roomsNeededForTarget – occupiedRooms;
if (roomsDifference > 0) {
roomsNeededForTargetResultElement.innerText = "To reach your target of " + targetOccupancyPercentage.toFixed(2) + "%, you would need to occupy " + roomsNeededForTarget + " rooms (" + roomsDifference + " more rooms).";
} else {
roomsNeededForTargetResultElement.innerText = "You are currently at or above your target occupancy rate of " + targetOccupancyPercentage.toFixed(2) + "%.";
