Occupancy vs. Vacancy: Key Metrics Explained
Occupancy and vacancy rates are two sides of the same coin in commercial real estate. These metrics measure how much space in a property is occupied versus unoccupied. Together, they sum up to 100%. For example, if 90% of units in a building are rented (occupancy rate), the remaining 10% are vacant (vacancy rate).
Here’s why these numbers matter:
Occupancy Rate: Indicates how well a property is performing. Higher rates often mean strong demand and potential for rent increases.
Vacancy Rate: Highlights areas for improvement. Higher rates might signal overpriced rents or market oversupply.
As of Q1 2025, the U.S. rental vacancy rate is 7.1%, within the healthy range of 5-10%. Understanding these metrics helps property owners make better decisions about pricing, marketing, and investments. For instance, apartment complexes often need at least 88% occupancy to cover costs, while hotels break even at 55%.
Quick Tip: Use simple formulas to calculate these rates:
Occupancy Rate = (Occupied Units ÷ Total Units) × 100
Vacancy Rate = (Vacant Units ÷ Total Units) × 100
These numbers directly impact revenue, property value, and market strategies, making them essential tools for property management and investment decisions.
How to Calculate Occupancy and Vacancy Rates
Basic Formulas for Calculation
In commercial real estate (CRE), these straightforward formulas are used to determine occupancy and vacancy rates:
Occupancy Rate Formula:
Occupancy Rate = (Occupied Units ÷ Total Units) × 100
Vacancy Rate Formula:
Vacancy Rate = (Vacant Units ÷ Total Units) × 100
These rates are directly related and always add up to 100%. For calculations that consider time-based factors, the vacancy rate reflects the percentage of time a property is unoccupied during a specific period. This is particularly useful for understanding income loss due to vacancies.
Time-Based Vacancy Rate Formula:
Vacancy Rate = (Days Vacant ÷ Total Days in Period) × 100
This formula helps property managers assess the financial impact of vacancies over a given timeframe.
Examples by Property Type
Take an apartment building with 120 total units, of which 11 are vacant. The vacancy rate would be:
(11 ÷ 120) × 100 = 9.2%
This means the occupancy rate is 90.8%, a typical target range for multifamily properties, where vacancy rates often fall between 5% and 10%.
Now, if one unit remains vacant for 23 days, the time-based vacancy rate is:
(23 ÷ 365) × 100 = 6.3%
This calculation provides insight into turnover periods and maintenance-related downtime, helping property managers better understand lost income over time.
Office Buildings
For office spaces, physical occupancy might be 80%, while economic occupancy - which accounts for rent collections and lease terms - could be closer to 90%. In some cases, overall figures may hover around 93.8%.
Mixed-Use and Retail Properties
The same formulas apply to retail and mixed-use properties, but managers often calculate separate rates for different types of spaces. These are then combined into a weighted average, typically based on square footage or revenue. This level of detail is particularly useful in mixed-use developments where various spaces contribute differently to the property’s overall performance.
Seasonal and Market Considerations
Market conditions play a big role in determining healthy occupancy levels. For instance, vacancy rates have risen in recent years, but in the multifamily rental sector, a vacancy rate of about 7% is often considered "good".
These calculations are essential for CRE financial analysis, supporting decisions like setting rental rates and evaluating property acquisitions.
What is Vacancy Rate and Occupancy Rate in Real Estate and How to Calculate them?
Impact on Financial Analysis and Decisions
Occupancy and vacancy rates play a key role in shaping financial decisions in commercial real estate (CRE). These metrics do more than just show how much of a property is leased - they directly influence rental revenue, net operating income (NOI), and, ultimately, the property’s market value.
Revenue Projections and Operating Income
How Revenue Is Affected
Occupancy and vacancy rates have a direct impact on a property’s NOI through rental revenue. Even small changes in occupancy can lead to noticeable shifts in income.
For example, a property generating $5 million in gross revenue could lose about $250,000 in rental income with just a 5% vacancy rate. This drop would significantly affect the NOI.
NOI and Property Value
There’s a tight connection between NOI and property valuation. As vacancy rates rise, NOI declines, which can lead to a drop in property value. Since income-based valuation methods rely heavily on NOI, keeping vacancies in check is essential to maintain or grow a property’s worth.
Improving Operating Performance
To maximize NOI, property owners need to focus on keeping rental rates competitive, reducing vacancies, and ensuring rent is collected on time. Proactive management is key - this can include building strong tenant relationships and using targeted marketing strategies. At the same time, rising operating costs, such as inflation and higher insurance premiums, can chip away at NOI. This makes controlling vacancies even more critical for maintaining financial stability and profitability.
Investment and Financing Decisions
Vacancy Risks and Cap Rates
Vacancy risks are an important factor in determining cap rates and shaping investment strategies. Properties with higher vacancy risks generally require higher cap rates since investors demand greater returns to compensate for the uncertainty. On the other hand, properties with low and stable vacancy rates are seen as safer investments, which can justify lower cap rates and result in higher valuations. This relationship heavily influences acquisition prices and expected returns.
Shifts in Market Strategy
As of the first quarter of 2024, U.S. office vacancy rates hit 19%, surpassing levels seen during the Great Recession and the COVID-19 downturn. This trend has pushed investors to rethink their strategies. Many are now leaning toward properties in sectors with more consistent occupancy rates or are demanding higher returns to balance the increased risks.
Investors are also focusing on stabilizing and improving occupancy to protect income streams and enhance property values. For example, some buyers are targeting properties where they can implement value-add strategies like renovations or upgrades. These efforts aim to attract tenants, raise occupancy rates, and boost NOI, making the investment more appealing and profitable in the long term.

Using Occupancy and Vacancy Data for Property Management
Occupancy and vacancy data play a key role in shaping leasing strategies, setting rental prices, retaining tenants, and managing properties effectively. These metrics offer valuable insights into market trends and tenant behavior, helping property managers adjust their operations to meet changing conditions.
Leasing and Pricing Decisions
Smart Pricing Strategies
Occupancy and vacancy rates are essential for determining rental prices. For example, if a property's occupancy exceeds 90%, it may indicate that rents are below market value and could be increased. National data, such as the projected 93.9% occupancy and 6.5% vacancy rates for 2025 - the lowest since 2013 - provides a benchmark for these decisions. Many property managers are also adopting flexible lease terms in response to these trends.
Focusing on Tenant Retention
Understanding the distinction between physical occupancy and economic occupancy is critical for tenant retention strategies. Physical occupancy measures how many units are occupied, while economic occupancy reflects the income generated. A property might show 95% physical occupancy but only 85% economic occupancy if tenants are behind on payments or benefiting from reduced rates.
“Understanding economic occupancy and physical occupancy is essential as it allows for in-depth assessment of the financial health of properties and make informed decisions.”
Retaining tenants is far more cost-effective than acquiring new ones, with turnover costs averaging $2,500 per unit. Industry benchmarks suggest aiming for retention rates of 60% for residential properties and 70% for retail or commercial spaces. Successful strategies include offering lease renewal incentives, maintaining clear and responsive communication, and ensuring rental rate increases align with market conditions.
Targeted Marketing Strategies
Occupancy trends also inform marketing efforts, helping property managers predict vacancy patterns and focus their outreach. Data-driven marketing can increase lead generation by 20% while reducing costs. These strategies ensure that properties remain competitive and adaptable to broader market changes.
Responding to Market Changes
Adapting to Seasonal and Economic Trends
Occupancy data can reveal seasonal and economic patterns that impact demand. For instance, properties in tourist-heavy areas may see annual occupancy fluctuations of up to 30%, requiring adjustments in pricing and marketing. Seasonal shifts, such as a -8% dip in winter and increases of +5% in spring and +3% in summer, help property managers forecast demand and allocate resources more effectively.
Investing in Property Improvements
Vacancy data can highlight when it's time to consider upgrades or operational changes. Properties with green certifications, for example, often achieve occupancy rates up to 15% higher than non-certified properties. This suggests that sustainability initiatives can be a smart investment, particularly when vacancy rates begin to climb.
Reevaluating Market Position
When occupancy rates drop below the ideal 90% threshold, it’s time to reassess a property's competitive standing. This could involve introducing flexible lease options, enhancing marketing messages to emphasize unique property features, or focusing on tenant engagement. Implementing feedback protocols and proactive engagement strategies can reduce turnover by up to 15%, ensuring the property remains attractive to current and prospective tenants.
