Work out amenity cost per guest instantly with clear inputs, formula shown and shareable results.
Amenity cost splits into a per-stay element, incurred once on arrival, and a per-night element consumed each day. Because the per-stay element is spread over the length of stay, longer stays have a materially lower amenity cost per room night.
Cost per stay
Per stay = Per-stay amenities + Nightly consumables x Average length of stay
Cost per night
Per night = Cost per stay / Average length of stay
Bulk dispensers instead of individual bottles, replenishing on request rather than daily, and removing items with low observed usage.
For amenities yes, and the same applies to housekeeping and check-in cost, which is why length of stay is such a strong profit driver.
