FSI Calculation

Floor Space Index (FSI) is also known as Floor Area Ratio (FAR) or Floor Space Ratio (FSR). It is the ratio of the total floor area of buildings on a certain location to the size of the land of that location or the limit imposed on such a ratio. Floor space ratio varies for different types of buildings. FSI calculation to find Floor Space Index can be done by entering the land area and number of flats, square feet area of the flats in the calculator.

Formula:

FSI = CA / LA Where, FSI = Floor Space Index CA = Total Constructed Area LA = Total Land Area

Example:

If the total constructed area and total land area is 10000 sq ft and 100000 sq ft, what is its FSI?

Solution:

FSI = CA / LA
= 10000 / 100000
= 0.1
