Average Length Of Stay (ALOS)

What is the definition of Average Length of Stay in the hotel industry?

 

ALOS stands for Average Length of Stay. It is the middling quantity of days visitors stay at the hotel during a specific period.

Formula:

Average Length of Stay (ALOS) = Number of room night / Number of reservations

How to compute:

Step 1

Span of stay = date of leave – date of admission

LOS of Guest E = [(4-4-2013) – (10-4-2013)] = 6

LOS of Guest F = [(2-4-2013) – (13-4-2013)] = 11

LOS of Guest G = [(15-4-2013) – (20-4-2013)] = 5

LOS of Guest H = [(22-4-2013) – (30-4-2013)] = 8

Step 2

Total span of Settlement: 6 + 11 + 5 + 8 = 30 days

Step 3:

Average Span of Stay: Total span of stay / Total number of reservations

30 / 4 = 7, 5 days

ALOS can differ a lot. A classic hotel in Amsterdam city hub has an ALOS of 1, 8 whilst a Resort situated in Bali can have a ALOS of 8,5.
