How much does each room in your hotel actually cost you per day? If you know the answer, you can make better decisions about pricing, budgeting and day-to-day operations. If you do not, then CPAR (cost per available room) is the metric you should add to your reports immediately. CPAR shows the total operating cost attributable to every available room, whether it was occupied or not. Put simply, it is the real “weight” each room carries every single day.
TL;DR
- CPAR = total operating cost ÷ (available rooms × days). An 80-room hotel with €876,000 in annual operating cost has a CPAR of €30 per room per day.
- CPAR is your break-even floor per available room. Compare it with RevPAR: RevPAR above CPAR means an operating profit, RevPAR below CPAR means an operating loss.
- Reducing CPAR lifts margin without touching price. Energy efficiency, PMS automation, smarter purchasing and staff training are the four places to start.
What CPAR measures, and why “available” matters
Most hoteliers have an intuitive sense of what a room costs when it is sold: the housekeeping time, the linen, the amenities, the breakfast. Far fewer think about what a room costs when it is empty. Yet the payroll is paid, the insurance is paid, the PMS subscription is paid and the building is heated or cooled regardless of whether anyone slept in room 214 last night.
CPAR captures exactly that. By dividing total operating cost by available room-nights rather than occupied room-nights, it spreads the full cost of running the hotel across every room you could have sold. The result is the daily cost burden each room must earn back before the hotel makes a cent of operating profit.
This is what makes CPAR different from cost per occupied room (CPOR). CPOR tells you what it costs to service a guest. CPAR tells you what it costs to exist. Both are useful; CPAR is the one that sets the floor for your pricing.
The CPAR formula
The calculation is simple:
| Step | Formula |
|---|---|
| Available room-nights | Number of rooms × days in the period |
| CPAR | Total operating cost ÷ available room-nights |
A worked example
An 80-room hotel has annual operating costs of €876,000.
- Available room-nights = 80 × 365 = 29,200
- CPAR = €876,000 ÷ 29,200 = €30 per room per day
That means every room, even one that never sells, “costs” the hotel €30 a day. Over a year, an unsold room does not cost nothing; it costs €10,950.
The same logic can be applied to any period. Calculate CPAR for a month, a season or a single week to see how the cost burden shifts as staffing levels and energy consumption change. A seasonal resort will typically see CPAR behave very differently in peak weeks, when higher staffing is matched by much higher revenue, than at the edges of the season, when the fixed base is carried by far fewer sold rooms.
What to include in total operating cost
CPAR is only as accurate as the cost base behind it. For a reliable figure, total operating cost should include:
- Payroll and employer contributions across all departments
- Cleaning, consumables and maintenance
- Energy: electricity, water and gas
- F&B supplies and cost of sales
- OTA commissions and marketing spend
- Insurance, administrative expenses, IT and PMS subscriptions
Leave out depreciation, interest, rent and taxes. These are real costs, but they belong to the ownership structure rather than the operation, and mixing them in makes it impossible to compare one hotel’s efficiency with another’s, or one year’s with the last.
Separate fixed from variable
One tip pays for itself many times over: split your costs into fixed and variable, so you know what proportion of CPAR moves with occupancy and what proportion does not.
| Fixed (largely independent of occupancy) | Variable (move with occupancy) |
|---|---|
| Core payroll and management salaries | Housekeeping consumables and laundry |
| Insurance | F&B supplies |
| IT, PMS and software subscriptions | OTA commissions |
| Administrative overheads | Guest amenities |
| Base energy load for common areas | In-room energy and water |
Knowing this split changes how you read the number. If most of your CPAR is fixed, then selling an additional room at almost any rate above its variable cost improves your position, because the fixed costs are being paid anyway. If most of your cost base is variable, the calculation is very different, and discounting becomes far more dangerous.
Why CPAR matters
CPAR shows the minimum level of revenue you need per available room to cover your operating costs. If your CPAR is €30, then any average rate below €30 produces a loss per available room, and since RevPAR is always at or below ADR, a rate that low guarantees the hotel is losing money on its inventory.
More usefully, you can set CPAR directly against RevPAR to assess operating efficiency:
| Comparison | Meaning |
|---|---|
| RevPAR > CPAR | The operation is profitable |
| RevPAR < CPAR | The operation is running at a loss |
Worked example
RevPAR of €55 against a CPAR of €30 leaves a net operating profit of €25 per available room per day. For the 80-room hotel above, that is €25 × 29,200 available room-nights, or €730,000 of gross operating profit for the year.
This gap between RevPAR and CPAR is, in fact, GOPPAR (gross operating profit per available room) when total revenue is used. The three metrics are one family: RevPAR is what you sell, CPAR is what it costs, and the difference is what you keep.
Using CPAR in pricing decisions
Once you know your CPAR, several decisions become clearer:
- Rate floors. You know the level below which a rate is destroying value rather than filling rooms. Combine this with your variable cost per occupied room to set a rational floor for last-minute and distressed inventory.
- Budgeting. A CPAR target per season, with fixed and variable components, gives department heads a concrete number to manage against rather than a vague instruction to “watch costs”.
- Opening and closing decisions. For seasonal properties, comparing forecast RevPAR with CPAR for the shoulder weeks tells you whether opening earlier or closing later actually adds profit.
How to improve your CPAR
Some strategies for reducing operating cost without affecting quality:
Energy efficiency. LED lighting throughout, smart thermostats that respond to occupancy, and key-card systems that cut power to unoccupied rooms. Energy is one of the largest variable lines in most hotels and one of the few where investment pays back quickly and permanently.
Automation through your PMS. Fewer manual tasks mean fewer hours. Automated check-in and check-out, housekeeping task allocation, rate distribution via the channel manager and automated guest communication all remove repetitive work from the front office and reservations teams, and every hour saved reduces labour cost per available room.
Smarter procurement. Consolidate purchasing across departments, negotiate seasonal agreements with suppliers before the season starts, and standardise the items you buy. Fragmented, ad-hoc purchasing is one of the most common and least visible sources of inflated CPAR.
Staff training. Small changes to daily routines, from portion control in F&B to chemical dosing in housekeeping to closing doors in air-conditioned areas, can reduce waste by up to 10%. Training is cheap; waste is not.
Reducing CPAR increases your profit margin without changing a single rate. It is the one lever that works regardless of demand, regardless of the competition and regardless of what the OTAs are doing.
A word of caution
Cutting cost is not the same as cutting quality. Reductions that guests notice, such as thinner towels, slower service or a poorer breakfast, will show up in reviews, then in ADR, and finally in RevPAR. The goal is to remove waste, not value. The fixed/variable split and a departmental CPAR breakdown are what let you tell the difference.
Building CPAR into your reporting
CPAR only becomes powerful when it is tracked consistently. A few practical rules:
- Calculate it monthly, and roll it up by season and by year, so trends are visible before they become problems.
- Break it down by department where your accounting allows, so you can see whether Rooms, F&B or Spa is driving any change.
- Plot it next to RevPAR on the same chart. The gap between the two lines is your operating margin, and watching that gap is far more informative than watching either line alone.
- Compare like with like. A different CPAR in high season is expected; a rising CPAR at the same occupancy as last year is a warning.
Conclusion
CPAR is your hotel’s mirror. It shows how efficiently you operate relative to what you earn. You cannot always control demand, but you can always control your cost per room. When you know your CPAR, you can price with confidence, plan with precision and grow profit through strategy rather than hope.
Knowing your cost is the beginning of profitability.
