What it means
Any business that sells the use of space is really selling a perishable product, because an unsold room-night or an empty desk cannot be stored and sold tomorrow. Occupancy rate is the headline measure of how much of that perishable capacity is converted into revenue.
It is one of the few operating metrics that a landlord, a hotelier and a care home operator would all recognise instantly. The reason it carries so much weight is that space-based businesses have very high fixed costs.
Rent, rates, insurance, security and most staffing barely move whether a building is half full or full, so each extra percentage point of occupancy drops a large share of its revenue straight to profit. That is also why occupancy falls hardest and fastest in a downturn.
Occupancy on its own can mislead, which is why it is almost always read next to price. A hotel can fill every room by cutting rates to a level that loses money, so the industry pairs occupancy with average daily rate and combines the two into revenue per available room.
Commercial landlords do the same by reading occupancy alongside the rent achieved per square foot. The denominator deserves attention because it determines whether the number means anything.
Rooms out of service for refurbishment, floors under fit-out and units withdrawn from the market are usually excluded from available capacity, and a business that quietly leaves them in will report a lower rate than its competitors on identical trading. The related nuance is the difference between physical and economic occupancy.
A block of flats can be 100% physically occupied while several tenants pay a discounted or promotional rent, so the economic occupancy, measured on rent actually collected against rent achievable at full price, may be closer to 90%.
In practice
Real-world examples.
Example
A serviced-office operator reports 88% occupancy across 400 desks, meaning 352 desks are let. Because its break-even point sits at 71% occupancy, the manager knows the 68 desks above break-even are carrying almost all of the site's profit.
Example
A hospital trust monitors bed occupancy weekly and finds it running at 96%. Clinical leaders treat anything above 92% as a warning sign, because there is no slack to absorb emergency admissions and discharge delays start to cascade.
Example
A self-storage business notices occupancy climbing from 79% to 91% over a summer. Rather than celebrate, it raises prices on new lettings by 8%, on the basis that near-full capacity is a signal that its rates are below what the local market will bear.
Think of it
“Occupancy rate shows how full your capacity is-utilization of your available space or resources.
Formula
Calculation
Occupancy Rate = (Occupied Units / Available Units) x 100
Take a 180-room hotel over a 30-day month.
Available room-nights = 180 rooms x 30 nights = 5,400
Room-nights sold during the month = 4,050
Occupancy Rate = (4,050 / 5,400) x 100 = 75%
Now suppose 10 rooms were closed for refurbishment for the whole month, removing 10 x 30 = 300 room-nights from supply. Available room-nights fall to 5,400 - 300 = 5,100, and the same 4,050 sold nights give an occupancy rate of (4,050 / 5,100) x 100 = 79.4%. The trading performance is identical; only the honesty of the denominator has changed.Case study
Seen in the real world.
Cedar Row Lodges is a fictional operator of 60 holiday cabins, created here purely to illustrate how occupancy behaves. In its first full year it achieved 21,900 available cabin-nights and sold 11,388 of them, an occupancy rate of 52%, with an average nightly rate of $180.
The owners assumed the answer was more advertising. A closer look showed weekend occupancy at 84% and midweek occupancy at 34%, so the shortfall was not demand in general but demand on Tuesdays. They introduced a discounted three-night midweek package aimed at retired couples and remote workers, priced 25% below the weekend rate.
Overall occupancy rose to 68% the following year while the average nightly rate fell to $166. Revenue still increased, because the extra nights more than offset the lower rate, and this illustrative example shows why occupancy should never be judged without looking at price alongside it.
Watch out
Common mistakes.
- Chasing occupancy as a goal in its own right. Filling capacity at a rate below marginal cost raises the percentage and lowers the profit.
- Leaving unusable capacity in the denominator. Rooms or units genuinely out of service should be excluded, or the figure will understate real trading performance.
- Reading a single blended number. An 80% average can hide 95% at one site and 60% at another, and only the site-level split tells you where to act.
Questions
People also ask.
What is a good occupancy rate?
It depends entirely on the sector and on where your break-even sits, so the meaningful test is the gap between current occupancy and the level at which the site covers its fixed costs.
What is the difference between occupancy rate and vacancy rate?
They are mirror images: a 92% occupancy rate is the same thing as an 8% vacancy rate, and property markets simply tend to quote the vacancy version.
Should discounted lettings count as occupied?
Yes for physical occupancy, but it is worth also tracking economic occupancy, which measures rent actually collected against rent achievable at full price.
