What this calculator does
Occupancy rate measures how full a property actually was over a period, expressed as a percentage of occupied units, rooms or room-nights against everything that was available to be occupied. It is one of the most widely quoted performance figures in hospitality and residential or commercial property management, because it answers the basic question of whether space is sitting empty or earning income.
The maths is a plain ratio, but the two numbers that go into it need to be counted consistently. A hotel typically tracks room-nights (rooms multiplied by the number of nights in the period) rather than just room count, while a residential landlord with several units might simply compare occupied units to total units at a point in time. Either way, occupied and available need to be measured on the same basis for the percentage to mean anything.
The formula
Divide the number of occupied units or room-nights by the total number available over the same period, then multiply by 100 to express it as a percentage.
| Term | Meaning |
|---|---|
| Occupancy rate | The percentage of available capacity that was actually occupied over the period. |
| Occupied units or room-nights | The count of units, rooms or room-nights that had a paying occupant. |
| Total available units or room-nights | The full capacity available to be occupied over the same period, whether or not it was. |
The inputs explained
| Field | What to enter |
|---|---|
| Occupied units or room-nights | The number of units, rooms or room-nights that were actually occupied over the period being measured. |
| Total available units or room-nights | The total units, rooms or room-nights available over that same period, occupied or not. |
When to use it
Reviewing a hotel's monthly performance
Comparing occupied room-nights to total available room-nights for the month gives the standard hospitality occupancy figure used in performance reporting and benchmarking against competitors.
Assessing a rental portfolio
A landlord with multiple units can compare occupied units to total units at any point to see how much of the portfolio is currently earning rent, and track that figure over time.
Setting a break-even occupancy target
Once fixed costs and rents are known separately, this figure tells a property owner where actual performance sits against the occupancy level needed just to cover costs.
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
Occupancy rate at a fixed 300 available room-nights
A fixed monthly capacity of 300 room-nights, at a range of occupied counts.
Occupancy rate at a fixed 90% occupied share, varying property size
A landlord holding a steady 90% occupancy share across portfolios of different sizes.
Questions
What is a good occupancy rate?
It varies heavily by property type, location and season. Hotels often target somewhere in the 60 to 80 percent range depending on the market, while residential rentals are frequently expected to run much higher, often above 90 percent, since vacancy directly costs a landlord rent.
Is this the same as the occupancy load calculator?
No. The occupancy load calculator works out the maximum number of people a floor area can safely hold under building codes, an entirely different, safety-focused concept. This calculator measures how full a property actually was over a period, a performance metric, not a legal capacity limit.
Should I use units or room-nights?
Use whichever measure matches your reporting period. A snapshot occupancy (units occupied right now versus total units) suits a simple portfolio review, while room-nights are the standard for hotels and short-term rentals, since they properly account for varying stay lengths within the same period.
How does occupancy rate relate to revenue?
Occupancy rate on its own does not capture the rate actually charged. A property can be fully occupied at low rents and earn less than a partially occupied property charging much more, which is why occupancy is usually reviewed alongside average rate metrics, not in isolation.
