What CPOR actually measures
Cost per occupied room is total housekeeping cost divided by occupied room nights over the same period. Occupied, not available: a room nobody slept in did not need cleaning, and dividing by inventory flatters the number in a way that makes a quiet month look efficient.
The metric matters because it is the only housekeeping figure that survives a change in occupancy. Payroll rises and falls with the season and tells you very little on its own. CPOR tells you what a room costs whether you sold sixty of them or a hundred and sixty, which is what makes it comparable month to month, property to property, and in-house against outsourced.
Divide by occupied room nights, never by available rooms. It is the most common way a CPOR gets quietly flattered.
Everything that belongs in the numerator
This is where most in-house calculations go wrong. Wages are the visible cost and usually somewhere around half the true one. A CPOR that only counts wages is not a costing, it is a payroll report.
The costs that never make the line
Three costs sit outside housekeeping in almost every hotel P&L, and all three are caused by housekeeping.
The first is turnover. Room attendant roles churn, and every departure costs a recruitment cycle plus weeks of a new attendant working below rate. The second is the front-desk cost of rooms not ready at check-in: the queue, the comp, the upgrade given away to move someone out of the lobby. The third is the review. A cleanliness complaint costs rate for months, and it lands in marketing rather than housekeeping.
None of these belong in a wage line, and all of them are the reason the wage line is misleading. A property with a low apparent CPOR and a persistent cleanliness score problem is not cheap; it is deferring the cost somewhere it cannot see.
Ask what a cleanliness-driven half-star on your review average is worth in rate over a year. That number is usually larger than the entire gap between an in-house and an outsourced CPOR.
Comparing in-house against outsourced
Once the numerator is honest, the comparison is straightforward, but only if both sides are quoted on the same basis. An outsourced rate that includes linen, supervision and cover is not comparable to an in-house wage figure that excludes all three.
Hotel housekeeping is quoted per property against your room mix and occupancy, with linen available on the same agreement. Every room is inspected by a supervisor against a 75-point standard with photo proof, and if a room misses the standard we re-clean it at no charge.
Moving the number without cutting the room
The fastest way to reduce CPOR is to clean rooms worse, which works for about a quarter before it appears in the review average and then in rate. The durable levers are structural rather than effort-based.
