Occupancy Rate

Occupancy rate is a fundamental capacity utilization metric that appears in industries where assets generate revenue only when they are in use. A hotel room that sits empty generates zero revenue but still incurs most of its operating costs. An airline seat that flies without a passenger represents almost pure lost revenue because the marginal cost of carrying an additional passenger — a meal, some incremental fuel — is trivial relative to the fare foregone. This cost structure makes occupancy rate a critical driver of profitability in capital-intensive service businesses.

For hotels, the calculation divides the number of rooms sold by the number of rooms available for sale over a period. A 300-room hotel that sells 240 rooms on a given night has an occupancy rate of 80%. Occupancy rates at full-service urban hotels typically range between 65% and 85% in normal operating conditions, with luxury resort properties often managing seasonal highs above 90% and lows in the 40% to 50% range during off-peak periods.

Marriott targets specific occupancy levels for each of its brands and properties based on the demand characteristics of the local market and the revenue management strategy in place. Revenue management — dynamically pricing rooms based on demand forecasts, booking pace, competitive rates, and event calendars — is designed to optimize the product of occupancy and average daily rate, which together determine RevPAR.

In commercial real estate, occupancy rate measures the percentage of leasable square footage that is under active lease. Office, retail, and industrial REITs report occupancy as a central operating metric. A REIT with 95% occupancy across its office portfolio faces a very different financial and risk profile than one at 80%, even if the absolute rent per square foot is similar, because the unoccupied space carries fixed costs without generating revenue.

Airlines track occupancy through the related metric of load factor — seats filled as a percentage of seats available — which is discussed in the aviation context. The economics are similar: high fixed costs mean that incremental occupancy at virtually any positive fare contributes to covering fixed expenses.

Investors should evaluate occupancy trends in context of pricing strategy. A hotelier or property owner who achieves high occupancy by discounting aggressively may report strong occupancy but weak RevPAR or net operating income. The combination of occupancy and rate — not occupancy alone — determines profitability.
