Floor area ratio is the ratio of total usable area in a building to the total area of the land or plot on which it is constructed. The floor area ratio formula, therefore, is
Floor Area Ratio = Total usable building area / gross area of land on which the building is constructedFloor area ratio is determined by the municipal bodies of the area. Another name for FAR is Floor Space Ratio or Floor Space Index.
The floor area ratio calculator works on the basis of the following factors:
Height of the building
Size of the land parcel it is built on
Number of floors constructed
Usable area of the building
Let us see how to calculate floor area ratio using the floor area ratio formula as mentioned above.
For example,
A developer has a 45000 sq ft of land on which he has constructed 5 floors of 10000 sq ft each, the floor area ratio will be calculated as follows:
FAR = (5 X 10000) / 45000
FAR = 1.11
FAR doesn’t exceed more than 2.5 usually.
Violating the decided FAR in an area has severe consequences. The breach is detected at the time of verification for the completion certificate for the building. If the authorities detect any violation, they can charge the developers a hefty fine, hold the project or in some cases, the developer can be taken to the court. Hence, it is important to know the floor area ratio formula to make right calculations before construction of a project.
