What is CPOR?

Cost per Occupied Room (CPOR) measures how much it costs a hotel to service each room it actually sells. Most operators calculate it on rooms-department operating costs, the direct expenses of turning a sold room into a stay: housekeeping labor, laundry, guest amenities, cleaning supplies, and room-level utilities.

Some operators also track a broader cost per occupied room that loads in administrative and back-office overhead, to see the full cost each occupied room carries. Either way, CPOR is the natural counterweight to ADR: one tells you what a room earns, the other what it costs.

CPOR formula

CPOR = Total Rooms Operating Cost / Number of Occupied Rooms

• Total Rooms Operating Cost: rooms-department expenses for the period (housekeeping labor, laundry, amenities, supplies, room utilities). A broader version adds allocated administrative and overhead cost.
• Occupied Rooms: the number of occupied room-nights in the period.

Worked example (USD)

A hotel records $18,000 in rooms-department costs over a period with 600 occupied room-nights.

CPOR = $18,000 / 600 = $30 per occupied room

Set that against rate. If ADR over the same period is $150:

ADR - CPOR = $150 - $30 = $120 rooms-level contribution per occupied room

That $120 is roughly what each occupied room contributes before undistributed and fixed costs, which is exactly the kind of contribution that rolls up into GOP and GOPPAR.

Why CPOR matters

CPOR turns cost from an abstract line on the P&L into a per-room number you can act on. It does three things well:

• Protects margin: watched against ADR, it shows whether the spread between price and cost is healthy or eroding.
• Sets a rate floor: you should rarely sell a room below the marginal cost of servicing it, and CPOR is the starting point for knowing where that floor sits.
• Explains profit: because CPOR scales with occupied rooms, controlling it is one of the most direct ways to lift GOPPAR without touching rate.

A rising CPOR is not automatically bad if it comes with a richer guest experience that supports a higher ADR. The warning sign is CPOR climbing while ADR stays flat, because that quietly compresses the margin on every room you sell.

How to reduce CPOR

• Housekeeping productivity: schedule labor to occupancy and track rooms cleaned per hour so staffing matches the actual house.
• Fewer, longer stays: stayover cleans cost less than full departure cleans, so a higher ALOS lowers turnover cost per occupied room.
• Smarter supply and energy use: reduce amenity waste, buy supplies efficiently, and manage room-level utilities.
• Automate operations and back office: cutting manual work on housekeeping coordination and finance lowers the labor and overhead each room carries.

That back-office overhead is easy to overlook, but it lands on every occupied room. Guestara's hotel payments automates collection and reconciliation, trimming the manual finance work and revenue leakage that inflate the administrative cost sitting behind CPOR.
