You pay for every room, full or empty. So cost it that way.
A hotel is a capacity business. The rooms, the space, the kitchens and the front office are built and staffed to carry a full house, and they cost money whether the rooms are sold or stand empty. Yet capacity cost is routinely buried in occupancy averages and seasonal swings, so the cost of the empty room in low season is never booked and the high-occupancy night looks more profitable than it is. Capacity costing puts a real cost against occupancy, season and the idle slice.

Capacity cost in hospitality is the cost of standing ready to fill the house, and it is paid whether rooms sell or not, which occupancy and RevPAR averages bury. The established costing convention puts practical capacity at 80 to 85 percent of theoretical, and research consistently finds most organisations never measure the cost of the unused slice, which in low season is large. TDABC computes a capacity cost rate per room and resource and assigns it by real occupancy and season through time equations, so the cost of empty capacity becomes visible and a high-occupancy night is costed honestly. We hold no hospitality-specific capacity benchmark; the logic of capacity costing is what we apply.
Occupancy hides the cost, season by season.
The capacity of a hotel stands ready every night, sold or not, and it is paid for in full. An annual occupancy average flatters the empty low season and penalises the busy high season, so the cost of the idle room is never booked where it actually occurs. A high-occupancy night then looks more profitable than it is, because the capacity it consumes is priced at a blended rate that has already absorbed the empty nights nobody costed. The real shape of the cost only appears when capacity is priced per room and assigned by real occupancy and season.
Empty rooms are paid for in full
The capacity stands ready whether sold or not. The established convention puts practical capacity at 80 to 85 percent of theoretical, and the unused slice, large in low season, is almost never measured.
Seasonality hides the real cost shape
Averaging cost across the year flatters the low season and penalises the high season. A flat occupancy view never shows where capacity cost actually bites.
High occupancy is mistaken for high profit
A full house of high-commission, high-touch demand can earn less than a quieter house filled direct. Occupancy alone says nothing about the cost of filling the rooms.
Capacity decisions run without a cost signal
Refurbishment, room-count and staffing decisions are justified on occupancy and RevPAR, rarely against the true cost of the capacity already standing idle.
Cost per room-night, idle slice made explicit.
The capacity cost rate is the cost of practical capacity divided by the practical capacity itself, the 80 to 85 percent of theoretical a property can actually sustain. Apply it per occupied room-night, add the reserved and standby capacity attributable to the period weighted by season, make the share of unused low-season capacity explicit rather than buried, and hold the front-office, housekeeping and space-readiness cost against capacity. The empty night then carries a real number, and the high-occupancy night is costed honestly.
Room-night capacity cost = practical capacity cost / practical capacity (80-85% of theoretical) applied per occupied room-night + reserved / standby capacity attributable to the period (season-weighted) + share of unused-capacity cost in low season (made explicit, not buried) + front-office, housekeeping and space-readiness cost held against capacity
Illustrative structure, not a measured benchmark. The explicit low-season idle term is what an occupancy average buries.
In the idle slice and the seasonal swing.
The margin leaks in the rooms and readiness paid for whether sold or not, buried in an occupancy average that never books the empty low-season night. Compute a real capacity cost rate per room and resource and assign it by occupancy and season, and the cost of empty capacity surfaces while the high-occupancy night is costed honestly. There is no hospitality case in our base and we do not invent one; what we apply is the transversal capacity-costing evidence and the discipline of a real capacity cost rate.
Frequently asked questions
- How should hotel capacity cost be allocated?
- By a capacity cost rate per room and resource, assigned by real occupancy and season, not buried in an annual occupancy average.
- What is the cost of empty rooms?
- The cost of capacity standing ready and not sold. The established convention puts practical capacity at 80 to 85 percent of theoretical, and this idle cost, large in low season, is almost never measured.
- How does capacity costing relate to TDABC?
- The capacity cost rate is the engine of TDABC; it converts the cost of a room or resource into a rate per unit of practical capacity, then assigns it by real occupancy.
- Is there a standard occupancy-cost figure for hotels?
- No, and we will not invent one. We apply the capacity-costing method and transversal evidence to your own occupancy and seasonal data.
