Cost per available room (CostPAR)

Cost per available room per night (often referred to as CostPAR) measures the total operating expense required to keep a room available for sale for one night. Unlike metrics that only look at sold rooms, this KPI accounts for every room in your inventory, regardless of whether it is occupied or empty.

Why does Cost per available room matter in hotels?

Cost per available room is a financial baseline. It helps you understand how much it costs to keep your doors open and your rooms ready for guests.

Many property owners focus strictly on the costs associated with a specific booking, such as laundry or breakfast. However, this approach can overlook the fixed costs you pay even when the property is empty, such as insurance, software subscriptions, salaries, and mortgage payments.

Understanding this metric helps you:

• Estimate your break-even point: You can estimate the minimum nightly revenue per room needed to cover typical operating costs.
• Set informed floor rates: It acts as a safety guide for your pricing strategy. When you want to offer last-minute deals or lower rates to fill capacity, knowing your CostPAR helps you avoid discounting below your typical operating cost.
• Monitor spending: It highlights when operational expenses are rising faster than your ability to consistently sell rooms.

If your Cost per available room is higher than your Revenue Per Available Room (RevPAR), you are likely operating at a loss for that period, all else equal.

What does Cost per available room usually look like in hotels?

There is no single "good" benchmark for Cost per available room because it depends entirely on your business model, location, and service level. Consider how property type and location can affect this metric:

• Full-service hotels: These properties typically have a higher Cost per available room. They often require 24/7 reception staff, restaurant teams, and maintenance for amenities like pools or gyms.
• Vacation rentals and apartments: These often have a lower Cost per available room. Without a front desk or daily housekeeping, the daily operational expense can be lower.
• City center vs. rural: Properties in major cities often face higher rent, taxes, and labor costs compared to rural accommodations, which can drive up the cost per room.

Travelers often look for data on the "average cost of a hotel room per night" to find the best deals, but that refers to the price they pay (ADR). For you, a high CostPAR is not necessarily negative if your ADR comfortably covers it. A luxury hotel may accept a higher cost structure to support a premium experience and rates. The risk arises when your costs are high, but your guest experience and price positioning do not match that investment.

How do you calculate Cost per available room?

To calculate this metric, you need your total operating expenses for a specific period and the total number of room nights available in that same period.

Cost per available room = Total Operating Costs ÷ Total Available Room Nights

Consider the following example:

• Total operating costs for the month (fixed + variable): $45,000
• Number of rooms: 15
• Days in the month: 30
• Total Available Room Nights: 450 (15 rooms × 30 days)

$45,000 ÷ 450 = $100

This calculation means it costs you $100 per night to maintain each room, whether you sell it or not.

What is the difference between Cost per available room, CPOR, and LPAR?

These metrics are often confused, but they serve different purposes in your financial analysis. In practice, they differ as follows:

• Cost per available room (CostPAR): It spreads all costs (fixed and variable) across all rooms (sold and unsold). It provides a view of total asset efficiency.
• Cost Per Occupied Room (CPOR): It focuses on the variable costs associated with a guest actually staying (housekeeping, amenities, breakfast). It divides costs only by the number of sold rooms.
• Labor Cost Per Available Room (LPAR): It isolates staffing costs—often a major expense—divided by available rooms. It helps you assess whether your team size aligns with your inventory size.

Example of how they move differently:
If you have a month with low occupancy, your CPOR may remain relatively stable because laundry costs do not change much per guest. However, your Cost per available room can increase because your fixed costs (rent, salaries) are spread across the same number of available rooms but supported by fewer bookings.

What factors influence Cost per available room?

Several operational elements impact this number directly.

1. Fixed Costs: Rent, mortgages, property taxes, and insurance are often major drivers. These do not fluctuate with occupancy.
2. Labor Efficiency: Staffing is often the biggest expense. Inefficient scheduling or manual tasks can increase the cost per room (LPAR).
3. Utility Costs: Heating, cooling, and electricity bills affect the daily cost of maintaining inventory.
4. Maintenance and Upkeep: Older buildings often require more frequent repairs, raising the baseline cost.
5. Technology Costs: While software subscriptions add to expenses, automation tools can reduce manual workload, which may lead to a lower cost per room over time.

How do you improve Cost per available room in your hotel?

Reducing your cost per room does not have to mean cutting quality. It often means optimizing how you operate so that you spend less on administration and inefficiencies. Here are four strategies to consider.

1. Automate repetitive administrative tasks

Labor is a major component of daily costs. If your staff spends hours manually entering data, answering repetitive questions, or processing payments, your cost per room can rise.
Using software to handle guest communication, check-ins, and payment processing can reduce time spent on routine tasks. This can help your team manage the same number of rooms with less manual effort and focus on higher-value guest interactions.

2. Implement preventive maintenance

Waiting for equipment to break is expensive. Emergency repairs often come with overtime charges and potential refunds to unhappy guests.
A scheduled maintenance plan helps you address small issues before they become major disruptions, which can make monthly operational costs more predictable over time.

3. Review vendor contracts and utility usage

Regularly auditing your suppliers can surface opportunities to streamline expenses. This includes:

• Renegotiating laundry or cleaning contracts.
• Installing energy-efficient lighting and smart thermostats to help reduce utility usage and costs over time.
• Reviewing software subscriptions to ensure you are not paying for tools you do not use.

4. Optimize inventory distribution

While this sounds like a revenue task, it also affects costs. If you rely heavily on channels with high commissions, your "cost of acquisition" becomes part of your total operating expense.
Encouraging more direct bookings can reduce reliance on higher-commission channels, which may lower average distribution costs and keep more team attention on the guest experience.
