How to Calculate Annual Occupancy Rate
Understanding your property's performance is crucial for real estate investors, hotel managers, and Airbnb hosts. The Annual Occupancy Rate is a key performance indicator (KPI) that measures the percentage of time a property is rented out compared to the total time it is available for rent over the course of a year.
A high occupancy rate generally indicates strong demand and effective marketing, while a low rate may suggest pricing issues, seasonal fluctuations, or the need for property improvements.
The Occupancy Rate Formula
The calculation is straightforward. It compares the number of nights successfully sold against the total number of nights the unit (or units) was available to be sold.
Occupancy Rate = (Total Nights Occupied / Total Nights Available) × 100
If you manage multiple units (like a hotel or apartment complex), the formula expands:
Total Nights Available = Number of Units × 365 Days
Occupancy Rate = (Total Combined Nights Booked / Total Nights Available) × 100
Example Calculation
Let's look at a realistic example for a small boutique motel with 10 rooms operating for a full year (365 days).
- Total Units: 10
- Total Potential Nights: 10 units × 365 days = 3,650 nights
- Actual Nights Booked: Records show 2,400 nights were booked across all rooms.
Calculation: (2,400 / 3,650) × 100 = 65.75%
This means the motel was occupied roughly 66% of the time throughout the year. The remaining 34.25% represents the Vacancy Rate.
What is RevPAR?
This calculator also provides RevPAR (Revenue Per Available Room). While Occupancy Rate tells you how full you are, RevPAR tells you how well you are monetizing your inventory.
Formula: RevPAR = Average Daily Rate (ADR) × Occupancy Rate
If you lower your prices drastically to get 100% occupancy, your RevPAR might actually drop. The goal of revenue management is to find the sweet spot between a high Daily Rate and a high Occupancy Rate to maximize RevPAR.
What is a Good Occupancy Rate?
"Good" varies by location and property type:
- Hotels: Often aim for 65% – 80%.
- Vacation Rentals (Airbnb): Highly seasonal. A beach house might have 90% occupancy in summer but 20% in winter, averaging 55% annually.
- Long-term Rentals: Should aim for 95%+, accounting only for turnover periods between tenants.
