Out of order room cost calculator

An out of order room costs nothing on a quiet night and a full rate on a sold-out one. Put in your own numbers to see what a repair that waits really costs, and how much a faster fix is worth.

Work out the cost

Use the numbers for the room type that is out of order, and the forecast for the nights it will be out, not the monthly average.

The rooms and the nights
Your rates

Other spend is what a guest typically spends on food, drinks, spa or parking per night. Moving a guest means the other hotel's rate, transport and any gesture you make.

How the calculator works

For each night, it compares two numbers: the rooms of this type you would sell at your forecast occupancy, and the rooms you can still sell with some out of order. When demand is higher than what is left, the difference is lost sales. When it is lower, the out of order rooms cost no room revenue that night.

  • Lost room nights = rooms you would sell, minus rooms still available, never less than zero, times the nights.
  • Room revenue = lost room nights times your average daily rate.
  • Other spend = lost room nights times what a guest spends per night outside the room rate.
  • Moving guests = guests already booked into rooms you can no longer give them, times the cost of moving each one.

It assumes every night in the period has the same forecast. If Friday and Saturday sell out and the weekdays don't, run it twice: once for the weekdays and once for the weekend.

A worked example

A hotel has 40 rooms of one type at an average rate of $180, and guests spend about $40 a night beyond the room. Two of those rooms are out of order for three nights while a part is on order.

Forecast occupancyRooms you would sellRooms you can sellLost sales a nightCost for 3 nights
75%30380$0
95%38380$0
100%40382$1,320

The same two rooms cost nothing on a quiet week and $440 a night on a sold-out one. That is the number to hold up against the cost of a faster fix. If an express courier for the part costs $90 and brings the rooms back two nights sooner on a sold-out weekend, it pays for itself many times over. If the hotel is at 75% all week, the part can come by the normal route.

Forecasts are averages. A week forecast at 90% can still have two sold-out nights. Check the nights one by one in your PMS or revenue system before deciding that a room can wait.

What the number leaves out

The calculator counts the money you can see. Some costs don't show up on the night.

  • Rooms sold with a known fault. Putting a guest in a room with a weak AC or a dripping shower to avoid the out of order list costs a refund, a free night or a room move at midnight, and often a review.
  • Forgotten rooms. The expensive out of order rooms are the ones nobody is working on. A room that waits a week for a part nobody ordered will be off sale on the busy nights too.
  • Upgrades you can't give. With fewer rooms of a higher type, you lose the chance to upgrade a loyal guest or sell an upgrade at check-in.
  • The repair itself. Parts and labor cost the same whether the room is back in one day or ten. The delay is what costs revenue.

How to keep out of order nights cheap

  1. Fix in order of demand. Look at the forecast every morning. A room that will be needed on Friday goes ahead of one that won't be needed until next month.
  2. Give every out of order room an owner and an end date. When the date passes, someone has to decide: extend it with a reason, or chase the part.
  3. Keep the usual parts on the shelf. AC capacitors and fan motors, shower cartridges, toilet fill valves and door lock batteries cause many out of order nights. Stock the ones your rooms actually use.
  4. Use out of service for small things. A stained headboard or a missing lamp is not a reason to take a room off sale on a sold-out night. The difference is explained in the guide to out of order and out of service rooms.
  5. Plan big jobs for quiet dates. Repainting, regrouting and full AC services belong on nights with spare rooms. The preventive maintenance schedule builder helps you see those jobs a year ahead.

In Turndown, a room is held out of order while its repair is open and released when the job closes, so it never sits on the list after the work is done. The Today screen lists today's arrivals with any room still blocked by an open job at the top, and the maintenance KPIs include rooms out of order and how long they waited.

Questions

How much does an out of order room cost a hotel?

It depends on demand for the nights it is out. If you still have spare rooms of the same type, it costs little or no room revenue. If that type sells out, each night costs the full rate plus whatever the guest would have spent in the hotel, and possibly the cost of moving a guest to another hotel.

How do you calculate lost revenue from out of order rooms?

For each night, take the rooms of that type you would have sold and subtract the rooms you can still sell. If the answer is above zero, that many sales are lost. Multiply by the average daily rate, add other spend per occupied room, then add any cost of moving guests who were already booked.

Does an out of order room affect occupancy?

In many systems out of order rooms are taken out of the rooms available count, so the hotel reaches full occupancy with fewer rooms. Other reports keep every room in the base. Check which base your PMS and your owner's reports use before comparing numbers.

Should I pay extra for a faster repair?

Usually, when the room would otherwise sit out of order on busy nights. The calculator shows the cost of each night out of order at your forecast occupancy. If an express part or an emergency call-out costs less than the nights it saves, it pays for itself.
