How to calculate FSI?

To calculate the Floor Space Index (FSI) of a building or plot of land, you need to determine the total built-up area of the building and divide it by the total area of the plot of land on which the building is constructed.

Here’s an example of how to calculate FSI:

Suppose you have a plot of land with an area of 500 square meters, and you want to construct a building with a total built-up area of 1000 square meters. To calculate the FSI, you would divide the total built-up area of the building (1000 square meters) by the total area of the plot of land (500 square meters):

FSI = Total built-up area of the building / Total area of the plot of land = 1000 square meters / 500 square meters = 2

So, in this example, the FSI would be 2. This means that the total built-up area of the building is twice the size of the plot of land. Depending on local regulations, this FSI value may or may not be allowed for construction on the given plot of land. It is important to check the local zoning and building regulations to ensure compliance.
