Enter the usable square footage (ft^2) and the pro-rata share of the common areas of the building (ft^2) into the Calculator. The calculator will evaluate the Rentable Square Footage.

## Rentable Square Footage Formula

RSF = USF + PRC

Variables:

- RSF is the Rentable Square Footage (ft^2)
- USF is the usable square footage (ft^2)
- PRC is the pro-rata share of the common areas of the building (ft^2)

To calculate Rentable Square Footage, add the usable square footage to the pro-rata share of the common areas of the building.

## How to Calculate Rentable Square Footage?

The following steps outline how to calculate the Rentable Square Footage.

- First, determine the usable square footage (ft^2).
- Next, determine the pro-rata share of the common areas of the building (ft^2).
- Next, gather the formula from above = RSF = USF + PRC.
- Finally, calculate the Rentable Square Footage.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

usable square footage (ft^2) = 2000

pro-rata share of the common areas of the building (ft^2) = 300
