Unlock your property's potential with our free FSI Calculator. Easily determine the Floor Space Index (FSI) or Floor Area Ratio (FAR) for your plot by entering the total plot area and the total built-up area of all floors. This essential tool helps architects, real estate developers, and homeowners understand the maximum permissible construction area, ensuring compliance with local zoning regulations and optimizing building plans for residential or commercial projects.
Formula:
The formula to calculate Floor Space Index (FSI) or Floor Area Ratio (FAR) is straightforward:
FSI = (Total Built-up Area of all Floors) / (Total Plot Area)
Where:
- Total Built-up Area: The sum of the covered areas of all floors in a building, including basements, stilt parking, and other specific areas as defined by local municipal bylaws.
- Total Plot Area: The entire area of the land parcel or plot on which the building is constructed.
Example: If your plot area is 2000 Sq. Ft. and the total built-up area across all floors is 2500 Sq. Ft., then the FSI is 2500 / 2000 = 1.25. This ratio helps determine the intensity of land use.
