What is Vacancy Rate?
Vacancy rate is a key metric in rental property management that measures the percentage of units in a property or portfolio that are unoccupied at a given time. It serves as a critical indicator of a property's performance and is widely used by landlords, property managers, and real estate investors to assess demand, forecast revenue, and make informed investment decisions.
Understanding vacancy rate matters because every vacant unit represents lost rental income. For landlords, a rising vacancy rate can signal issues with pricing, property condition, marketing, or local market conditions. For investors, vacancy rate is essential for evaluating potential acquisitions and comparing properties across different markets. Lenders also consider vacancy rates when underwriting loans for rental properties, making it a figure that directly impacts financing terms.
Physical vs. Economic Vacancy Rate
There are two common ways to measure vacancy. The physical vacancy rate is the simplest: it counts how many units are physically unoccupied relative to the total number of units. The economic vacancy rate goes further by measuring the actual number of days units sit vacant over a period, giving you a more precise view of income loss over time. A unit that was vacant for half a month, for example, contributes less to economic vacancy than one empty for the full month.
Vacancy rate and occupancy rate are two sides of the same coin. If your vacancy rate is 8%, your occupancy rate is 92% (calculated as 100% − Vacancy Rate). Both metrics are useful, but vacancy rate is more commonly referenced when discussing areas for improvement, while occupancy rate is often used to highlight portfolio strength.
How to Calculate Vacancy Rate
Three formulas every landlord and investor should know
Physical Vacancy Rate
The most straightforward calculation. Divide the number of vacant units by the total number of units, then multiply by 100 to get a percentage.
Physical Vacancy Rate = (Vacant Units ÷ Total Units) × 100
Worked Example
If you have 20 units and 3 are vacant:
(3 ÷ 20) × 100 = 15% vacancy rate
Occupancy Rate
Occupancy rate is the inverse of vacancy rate. Once you know one, you immediately know the other.
Occupancy Rate = 100% − Vacancy Rate
Using the example above, a 15% vacancy rate means an 85% occupancy rate.
Economic Vacancy Rate
This time-based formula captures partial vacancies and gives a more accurate picture of revenue loss. Instead of simply counting empty units, it measures how many rentable days were actually rented.
Economic Vacancy Rate = ((Total Rentable Days − Actual Rented Days) ÷ Total Rentable Days) × 100
For example, if your portfolio has 600 total rentable days in a month and tenants occupied units for 540 of those days: ((600 − 540) ÷ 600) × 100 = 10% economic vacancy rate.
Skip the manual math. The calculator above handles all three calculations automatically. Enter your property details and get instant results for physical vacancy rate, economic vacancy rate, and occupancy rate in one step.
What is a Good Vacancy Rate?
Context matters — here is how to interpret your results
There is no single “good” vacancy rate that applies to every situation. What counts as healthy depends on your local market, property type, and asset class. A vacancy rate that is perfectly normal in a rural area might signal problems for a Class A apartment building in a major metro. That said, the national average for residential rental properties in the United States typically falls between 6% and 7%, which can serve as a useful baseline.
Vacancy Rate Rating Scale
This calculator uses the following scale to rate your vacancy rate, which aligns with widely accepted industry benchmarks:
Tips for Reducing Your Vacancy Rate
- Price competitively. Research comparable rentals in your area and adjust rents to stay aligned with the market. Overpricing is one of the most common causes of extended vacancies.
- Minimize turnover time. Start marketing units before current tenants move out and streamline your make-ready process so units are rent-ready within days, not weeks.
- Invest in tenant retention. Respond quickly to maintenance requests, maintain clean common areas, and consider modest renewal incentives. Keeping a good tenant is almost always cheaper than finding a new one.
- Improve your listing quality. Use professional photos, write detailed descriptions, and list on multiple platforms to maximize exposure and attract qualified applicants faster.
