Floor Space Index Calculator

Formula

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

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

Where:

\(\text{FSI}\) is the Floor Space Index
\(\text{TFA}\) is the Total Floor Area (sq ft or sq m)
\(\text{TA}\) is the Total Area of the plot (sq ft or sq m)

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:

Total Floor Area (TFA) = 5000 sq ft
Total Area of the Plot (TA) = 2000 sq ft

Using the formula to calculate the Floor Space Index:

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

The Floor Space Index is 2.5.
