How to calculate amenity cost per occupied room
Quoting a price per bottle tells you little. The number that helps you decide is cost per occupied room per night. Here is how to get it.
Why per occupied room
Amenities are consumed by guests, not by rooms. An empty room costs nothing in shampoo. So the useful unit is cost per occupied room night (CPOR). It lets you compare a small bottle with a dispenser, and one supplier with another, on equal terms.
Use the same period and the same method every time, or month-to-month comparisons will mislead you.
The basic formula
Add up the total amenity spend for a period, then divide by occupied room nights for the same period.
- Total amenity spend, including delivery and any wastage you write off.
- Occupied room nights from your reports.
- CPOR = spend divided by room nights.
Use at least a full month, ideally a quarter, so seasonal swings do not distort it.
If you run several room types, calculate CPOR for each. A suite with a fuller set will cost more than a standard room, and averaging hides that. It also helps you see whether the extra items in premium rooms earn their place.
A worked example (illustrative)
For example, a 60-room hotel with 70% occupancy has about 1,260 occupied room nights in a 30-day month. Suppose it spent 63,000 on amenities including freight. CPOR = 63,000 divided by 1,260, which is 50 per occupied night. These numbers are illustrative only. Replace them with your own.
If a switch to a different format cut spend to 45,000, CPOR falls to about 36. That is the figure to compare, not the unit price of any single item.
Try a second case. Suppose a 30-room guesthouse at 55% occupancy has about 495 occupied nights in a month, and spends 12,000 on amenities. CPOR is about 24. If a delivery of damaged bottles added 1,500 in write-offs, the true figure is nearer 27. Wastage is often the line that explains why two similar hotels have different numbers.
Costs people forget
- Freight and handling, especially for imported goods.
- Wastage: opened products removed at checkout, breakage, damp-damaged stock.
- Staff time in restocking and checking.
- Storage: space tied up by large minimum orders.
- Dispenser hardware if you move to refills, spread over its expected life.
One practical tip: keep a simple wastage log by the store. Note each write-off with the date and reason, such as leaking pump, damp carton or guest took the full bottle. After a quarter you will see patterns that a supplier discussion or a storage change can fix.
Comparing formats fairly
A miniature has a visible unit cost and often a high usage rate because many guests take them. A refill system has a higher upfront cost for fittings and a lower cost per use. To compare, calculate for each: unit or refill cost, expected usage per occupied night, hardware cost per room divided by its life in nights, and added labour. Look at both miniatures and refill systems against your own occupancy.
Be careful with usage assumptions. Guests do not all use the same amount; long stays and families raise use, while one-night business stays often leave products untouched. Track real consumption from stock counts rather than rely on a supplier's estimate, and use their figure only as a starting point.
Using the number
Track CPOR monthly. If it rises without a change in suppliers, look at wastage and restocking habits first. Set a target range and review it with housekeeping. A figure that nobody sees will not be managed.

CPOR also helps when negotiating. Showing a supplier your current CPOR and a target gives them a number to work towards, such as a different pack size or a simpler label. It turns a general price conversation into a design problem both sides can solve.
A quick monthly routine
Set aside thirty minutes at month end. Pull occupied room nights from the PMS report, total the invoices and write-offs, calculate CPOR and note it beside last month's figure. Add one line explaining any change greater than a few per cent. After six months you will have a trend that tells you whether supplier, format or staff habits are moving the number.
Questions on this topic
What is a good CPOR?
It depends on your segment and room rate. Set a target as a share of average room revenue, then watch the trend.
Should I count empty rooms?
No. Use occupied room nights only, since unused rooms do not consume amenities.
How often should I recalculate?
Monthly is sensible. Recalculate fully after any change in supplier, format or par level.
