Calculator guide
How this calculator works
How to use this calculator
Enter the number of vacant units and total rentable units. The calculator shows the vacancy rate and occupancy rate.
Formula used
Vacancy Rate = Vacant Units ÷ Total Units × 100
Example calculation
If 4 units are vacant out of 80 total units, the vacancy rate is 5.00% and the occupancy rate is 95.00%.
What the result means
Vacancy rate helps estimate how much of a rental property is not producing rent. Lower vacancy usually means stronger occupancy performance.
Frequently asked questions
Can I use this for a single rental property?
Yes. For one unit, the vacancy rate is either 0% if occupied or 100% if vacant.
Is vacancy rate the same as occupancy rate?
No. Occupancy rate is the opposite of vacancy rate. Together they add up to 100%.
Why does vacancy rate matter?
Vacancy affects rental income, cash flow, and property valuation assumptions.
