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.
Occupancy isn't everything — RevPAR for hotels
Hotel industry uses RevPAR (Revenue Per Available Room) as primary KPI. RevPAR = ADR (Average Daily Rate) × Occupancy Rate.
Strategic implication. 90% occupancy at $150 ADR = $135 RevPAR. 65% occupancy at $250 ADR = $162.50 RevPAR. Higher rates compensate for lower occupancy.
Optimization approaches. (1) LUXURY POSITIONING — maximize ADR; tolerate lower occupancy. Best for unique market positions.
(2) VOLUME — maximize occupancy; lower ADR. Best for commodity rooms in competitive markets.
(3) REVENUE MANAGEMENT — dynamic pricing optimizes both. Holidays, events, weather affect pricing; algorithms adjust hourly. Best for properties with sophisticated revenue management systems.
STR data 2024. Average U.S. hotel: $151 ADR × 67% occupancy = $101 RevPAR. Higher-end luxury: $400+ ADR × 65% = $260+ RevPAR. Lower-end economy: $80 ADR × 75% = $60 RevPAR.
Healthcare bed occupancy and hospital economics
Hospital bed occupancy rate. Average U.S. hospital 65-70%. Higher than ideal for cost recovery; lower than ideal for emergency surge capacity.
Optimal range. 75-85%. Provides operational efficiency while preserving surge capacity. Hospital systems struggle to achieve consistently.
COVID-19 impact. Highlighted need for surge capacity. Hospitals near 100% occupancy during peaks couldn't accommodate emergency demand.
Strategic implications. (1) HOSPITAL CLOSURE — chronically low-occupancy hospitals (especially rural) face closure pressure. ~15% of rural hospitals closed 2010-2024.
(2) URGENT CARE EXPANSION — outpatient alternatives reduce hospital occupancy needs. Shifts cost structure.
(3) STAFFING MODELS — flexible scheduling, agency nurses provide capacity flexibility.
(4) FACILITY DESIGN — convertible space (PACU to ICU) provides surge capability.
Occupancy rate benchmarks (2024)
Reference occupancy benchmarks by industry.
| Industry | Average occupancy | Optimal range |
|---|---|---|
| U.S. Hotels (overall) | 67% | 70-80% sustainable |
| U.S. Hotels (luxury) | 62-68% | 65-75% |
| U.S. Hotels (economy) | 70-75% | 75-85% |
| Rental property (residential) | 92-95% | 95%+ |
| Office space (post-COVID) | 55-70% | 85-90% |
| Retail (mall) | 85-90% | 90%+ |
| Industrial/warehouse | 95%+ | 97%+ |
| Senior living | 85% | 90%+ |
| Hospital beds | 65-70% | 75-85% |
| Vacation rental (peak) | 70-85% | Depending on market |
Office space dramatically affected by hybrid work trends post-COVID. Office occupancy in major cities (NYC, SF) running 50-60% physically; vacancy from leased-but-unused space substantial. Industrial/warehouse near full occupancy reflecting e-commerce growth.
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.
When is this calculator unreliable?
When using single-point occupancy without context (occupancy fluctuates daily/weekly/seasonally; meaningful only at consistent point or with trend analysis). Also unreliable for revenue analysis without considering pricing (RevPAR for hotels — combines occupancy and ADR). For business decisions, use occupancy alongside revenue and cost metrics.

Methodology & Review
Occupancy rate equals (units occupied / total units) × 100. The calculator returns occupancy rate percentage. Used in hospitality (hotels, rentals), healthcare (hospital beds), aviation (flights), real estate (commercial leases), and other capacity-based businesses. U.S. averages 2024: hotels 65-70%; hospitals 65-70%; commercial real estate variable by sector; rental property 90-95% target. RELIABILITY: Reliable for direct ratio at point in time. Less reliable for averages (occupancy fluctuates daily; weekly average vs monthly average vs annual average differ); for revenue analysis (occupancy alone doesn't reflect pricing).
