CPOR Calculator – Cost Per Occupied Room
Understand Your Cost Per Occupied Room.
Use this free CPOR calculator to evaluate your hotel’s operating efficiency and make smarter, cost-conscious business decisions.
What is CPOR?
CPOR stands for Cost Per Occupied Room, a key metric in hotel operations that measures how much it costs to service each room that is actually sold.
Unlike revenue-based metrics like ADR or RevPAR, CPOR focuses entirely on expenses — helping hoteliers evaluate how efficiently they’re managing labor, amenities, housekeeping, and utilities. By calculating CPOR, you can identify unnecessary spending, compare costs between departments or properties, and set realistic financial targets.
This metric is especially useful for operational managers, finance teams, and owners looking to control margins without compromising guest experience.
CPOR Formula
The formula for calculating CPOR is:
CPOR =
Total Operating Costs
Occupied Rooms
To calculate it, divide your total operating costs during a specific period by the number of rooms that were actually occupied during that same period. These operating costs typically include expenses such as housekeeping, front office labor, cleaning supplies, linen services, in-room amenities, and energy costs.
For example, if your hotel spent $60,000 on operations over one month and sold 1,200 rooms, your CPOR would be $50. That means every occupied room costs you $50 to operate.
Why CPOR Matters for Hotel Profitability
Controlling costs is just as important as increasing revenue, and CPOR is one of the most effective ways to track expense efficiency on a per-room basis. A low CPOR can indicate strong operational control, while a high CPOR may suggest inefficiencies, overspending, or underutilized resources.
By monitoring CPOR over time, hoteliers can make data-driven decisions about staffing levels, amenity usage, and supplier negotiations. It also helps pinpoint the true cost of guest satisfaction, ensuring that service standards are met without unnecessary budget strain.
In multi-property groups, CPOR can be used to benchmark performance and highlight which properties are managing their operations most efficiently.
CPOR vs RevPAR, GOPPAR, and TRevPAR
While RevPAR and TRevPAR measure how much revenue your property is generating per room or per bed, CPOR tells you how much you’re spending to service each guest stay.
GOPPAR subtracts operating costs from revenue to show profit per room, but CPOR focuses purely on the cost side.
When used together, these metrics allow hotel managers and owners to strike a balance between pricing, sales volume, and operational efficiency. For example, a hotel with strong RevPAR but rising CPOR may still be losing profit. Only by measuring both revenue and cost can you truly optimize performance.
