How to use the occupancy calculator
Use totals from the same property, date range and inventory definition. Count room nights, not guests, bookings or arrivals. Read the result together with ADR (average daily rate) and RevPAR (room revenue per available room night).
What is the hotel occupancy formula?
Occupancy divides room nights sold by room nights available, then multiplies by 100. Sold room nights are the demand side; available room nights are the supply side.
Occupancy formula
Occupancy = sold ÷ available room nights × 100 Both figures must cover the same dates and the same inventory scope.
Available room nights
Available = rooms in inventory × nights For monthly occupancy, multiply your rooms by the nights in the month: 80 rooms over 30 nights give 2 400 available room nights.
Occupancy calculation example
An 80-room hotel calculates occupancy for a 30-night month with no inventory adjustment.
| Figure | Value | How it is calculated |
|---|---|---|
| Available room nights | 2 400 | 80 rooms × 30 nights |
| Room nights sold | 1 872 | From the PMS for the same month |
| Occupancy | 78% | 1 872 ÷ 2 400 × 100 |
In plain language, the hotel sold 78 out of every 100 room nights counted as available in this calculation.
What does your occupancy rate mean?
Occupancy shows how much of your room-night capacity was sold. It helps you spot demand patterns, compare equivalent periods and see how quickly future dates are filling.
There is no universal “good” occupancy. Higher occupancy is not automatically better performance: a hotel can fill more rooms by cutting rates and still earn less.
| Hotel | Occupancy | ADR | RevPAR |
|---|---|---|---|
| Rate-led hotel | 70% | €150.00 | €105.00 |
| Volume-led hotel | 85% | €110.00 | €93.50 |
Limitations and reporting assumptions
- Sold and available room nights must cover the same property, rooms, dates and reporting convention.
- Occupancy is based on room nights, not guests, beds, reservations or arrivals.
- Complimentary rooms, no-shows, day-use and owner use are treated differently by reporting purpose. Use one documented convention.
- The optional unavailable-room deduction is for an internal operational view. For benchmarking, follow your provider’s availability rules.
- A result above 100% usually signals mismatched data, though same-day room resale can also produce it.
Occupancy calculator FAQ
How do you calculate a hotel’s occupancy rate?
Divide room nights sold by room nights available for the same period, then multiply by 100. Selling 80 of 100 available room nights gives 80% occupancy.
How do I calculate available room nights?
Multiply the rooms in your chosen inventory by the nights in the period. An 80-room hotel has 2 400 room nights across 30 nights.
Should out-of-order rooms be excluded from occupancy?
It depends on the report. Internal operational reports may exclude rooms that genuinely could not be sold; benchmarking providers such as STR generally require full room-night availability, with specific rules for longer closures.
What is a good occupancy rate for a hotel?
There is no single good percentage. Compare against equivalent dates, seasonality, property type, market conditions and budget, and review ADR, RevPAR and costs alongside it.
Can hotel occupancy be above 100%?
It is unusual and should trigger a data check, but it can happen when the same room is sold more than once on one date, such as day-use followed by an overnight stay.
What is the difference between occupancy, ADR and RevPAR?
Occupancy measures the share of available room nights sold. ADR is average room revenue per room night sold. RevPAR is room revenue per available room night, so it reflects both.
What is the difference between room occupancy and bed occupancy?
Room occupancy shows what share of available room nights you sold, and it is what this calculator measures. Bed occupancy counts beds instead: guest nights divided by available bed nights (beds × nights), multiplied by 100. A twin room with one guest is a sold room but leaves one of its two beds empty, so bed occupancy is usually lower than room occupancy.
Is a 10% occupancy increase the same as 10 percentage points?
No. From 50% to 60% is 10 percentage points and a 20% relative increase, so a “10% increase” is ambiguous. Always state which one you mean.
