Enter the total number of units and the number of vacant units into the calculator to determine the vacancy percentage. This calculator helps in understanding the proportion of unoccupied units in a property.

Vacancy Percentage Formula

The following formula is used to calculate the vacancy percentage.

VP = (VU / TU) * 100

Variables:

  • VP is the vacancy percentage (%)
  • VU is the number of vacant units
  • TU is the total number of units

To calculate the vacancy percentage, divide the number of vacant units by the total number of units and then multiply by 100 to get the percentage.

What is a Vacancy Percentage?

Vacancy percentage is a metric used in real estate to indicate the proportion of all available units in a rental property, such as an apartment complex or office building, that are unoccupied at a given time. It is an important indicator of the property’s performance, rental demand, and overall market conditions. A high vacancy percentage may suggest a need for rent adjustments, improved marketing strategies, or property upgrades.

How to Calculate Vacancy Percentage?

The following steps outline how to calculate the Vacancy Percentage.


  1. First, determine the total number of units (TU) in the property.
  2. Next, determine the number of vacant units (VU) in the property.
  3. Next, gather the formula from above = VP = (VU / TU) * 100.
  4. Finally, calculate the Vacancy Percentage (VP).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
