Calculate Floor Space Index (FSI)



Formula

The formula to calculate the Floor Space Index (FSI) is:

\[ \text{FSI} = \frac{\text{TFA}}{\text{TA}} \]

What is a Floor Space Index?

Floor Space Index (FSI), also known as Floor Area Ratio (FAR), is a measure used in urban planning to limit the amount of construction in a certain area. It is the ratio of the total floor area of buildings on a certain location to the size of the land of that location. This index is used to control the density of buildings and prevent overcrowding in urban areas. Higher FSI values indicate higher potential for construction and development.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Floor Space Index:

\[ \text{FSI} = \frac{5000}{2000} = 2.5 \]

The Floor Space Index is 2.5.
