Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Occupancy rate | Vacancy rate |
|---|---|---|
| 2,400 of 3,000 | 80.00% | 20.00% |
| 270 of 365 | 73.97% | 26.03% |
| 44 of 50 | 88.00% | 12.00% |
| 880 of 1,200 | 73.33% | 26.67% |
How This Calculator Works
Enter the number of occupied units and the total available units for the period. The calculator divides one by the other to give the occupancy rate as a percentage, and shows the complement — the vacancy rate.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
A property with 2,400 occupied room-nights out of 3,000 available has an 80% occupancy rate, leaving a 20% vacancy rate. Measuring in the same unit on both sides keeps the figure accurate.
Key Insight
Occupancy rate only tells half the story. A high occupancy at a low price can earn less than a moderate occupancy at a strong price — which is why operators watch revenue per available unit alongside it.
Frequently Asked Questions
How is occupancy rate calculated?
Divide the number of occupied units by the total available units, then multiply by 100. It is the share of capacity that was used.
What counts as a unit?
Whatever you are measuring — room-nights for a hotel, rental months for a property, or seats for a venue. Use the same unit for both the occupied and available figures.
What is the vacancy rate?
The vacancy rate is the complement of occupancy — the share of capacity left empty. An 80% occupancy rate carries a 20% vacancy rate.
Is a higher occupancy rate always better?
Not necessarily. Very high occupancy can mean prices are set too low. Operators weigh occupancy against the rate achieved and revenue per available unit.
What occupancy rate is healthy?
It varies by property type and market. Compare against similar properties and your own past periods rather than a single universal benchmark.

Methodology & Review
Occupancy rate is occupied units divided by available units, expressed as a percentage. The complement is the vacancy rate. Units may be room-nights, rental months, or seats.
