Average Length of Stay (ALOS)
Average Length of Stay (ALOS) is the mean number of nights guests stay per reservation, calculated by dividing total booked nights by the number of reservations. It is a critical operational metric for short-term rental hosts because it directly impacts turnover costs, cleaning frequency, and revenue efficiency.
Key Takeaways
- ALOS = Total Booked Nights / Number of Reservations
- Longer stays reduce turnover costs and cleaning expenses per booked night
- Urban listings typically average 2-4 nights; vacation properties 4-7 nights
- ALOS interacts with ADR and occupancy rate to determine total revenue
- Length-of-stay discounts can increase ALOS but should be carefully calibrated
How to Calculate ALOS
Formula:
ALOS = Total Booked Nights / Number of Reservations
Example:
In a given month, your listing had 8 reservations totaling 26 booked nights:
ALOS = 26 / 8 = 3.25 nights per booking
To understand the cost impact, if each turnover costs $130 in cleaning and preparation:
- At 3.25-night ALOS: $130 / 3.25 = $40 turnover cost per booked night
- At 5-night ALOS: $130 / 5 = $26 turnover cost per booked night
- At 7-night ALOS: $130 / 7 = $18.57 turnover cost per booked night
Why ALOS Matters for Airbnb Hosts
- Turnover cost reduction: Each guest changeover requires cleaning, laundry, restocking, and inspection. Longer stays spread these fixed costs across more revenue-generating nights.
- Gap reduction: Shorter stays create more gaps between bookings. A calendar full of 2-night stays will have more unbookable orphan nights than one with 5-night stays.
- Revenue forecasting: ALOS combined with Average Transaction Value helps predict monthly revenue from a given number of bookings.
- Operational planning: Your ALOS determines cleaning team scheduling, supply restocking frequency, and overall operational workload.
ALOS Benchmarks
| Property Type | Typical ALOS | Key Drivers |
|---|---|---|
| Urban business travel | 2-3 nights | Weekday corporate stays |
| Urban leisure | 3-5 nights | Weekend and holiday getaways |
| Beach/coastal vacation | 5-7 nights | Saturday-to-Saturday patterns |
| Mountain/ski resort | 4-7 nights | Weekend warriors + week-long vacations |
| Rural/nature retreat | 3-5 nights | Long weekend escapes |
| Extended stay/furnished | 14-30+ nights | Relocations, remote workers |
How to Optimize Your ALOS
- Offer strategic length-of-stay discounts (e.g., 10% weekly, 20% monthly) that encourage longer bookings without deeply discounting your ADR
- Set minimum stays strategically during peak periods (3-night minimums on weekends, 5-7 nights during holidays) to attract longer bookings
- Target longer-stay guest segments like remote workers, traveling nurses, and relocating families through listing descriptions and amenities (workspace, washer/dryer)
- Reduce orphan nights by adjusting your minimum stay based on calendar gaps -- if you have a 2-night gap between bookings, temporarily lower the minimum to 2 nights
- Analyze your gross booking revenue by stay length to find the sweet spot where total revenue and operational efficiency are both optimized
Frequently Asked Questions
A good ALOS depends on your market and strategy. Urban listings typically see 2-4 nights, vacation properties 4-7 nights, and extended-stay or furnished rentals 14-30+ nights. The ideal ALOS balances revenue per night with turnover costs and cleaning expenses.
Divide the total number of booked nights by the total number of reservations in the period. For example, if you had 60 booked nights from 15 reservations, your ALOS is 4.0 nights per booking.
Generally yes, because longer stays reduce turnover costs, cleaning expenses, and vacancy gaps between bookings. However, there is a trade-off: weekly discounts that are too steep can reduce overall revenue. Aim for an ALOS that minimizes turnover costs while maintaining strong per-night rates.
