Formula
How this calculator works
This formula converts source operating values into alos for quick review.
ALOS = Occupied Room Nights ÷ Number of Stayed Reservations
Context
Why this metric matters
Decide whether to include comp, house-use, day-use, split stays, and no-shows. Use stayed reservations, not inquiries, for operational ALOS.
Hotel insight
Industry context
- Decide whether to include comp, house-use, day-use, split stays, and no-shows. Use stayed reservations, not inquiries, for operational ALOS.
- Small changes in denominator rules can move the result, so keep the same reporting basis when comparing periods.
Operational notes
Before you act on the number
- 2,700 occupied room-nights ÷ 1,200 reservations = 2.25 nights
- Confirm whether internal-use, complimentary, adjustment, or excluded activity should be included before comparing periods.
- Use this result as an operating guide and review it with the supporting business context.
