Floor Space Ratio Calculator

Formula

The formula to calculate the Floor Space Ratio (FSR) is:

\[ FSR = \frac{\text{Total Floor Area}}{\text{Total Land Area}} \]

Where:

\(FSR\) is the Floor Space Ratio
Total Floor Area is the sum of the floor area of all floors in the building (sq ft)
Total Land Area is the area of the land on which the building is constructed (sq ft)

What is Floor Space Ratio?

Floor Space Ratio (FSR) is a measure of the built-up area allowed on a given plot of land. It is a key determinant in zoning laws and building regulations, helping to control the density and massing of buildings. A higher FSR indicates a higher density of construction, which can impact infrastructure, traffic, and the overall character of a neighborhood.

Example Calculation

Let's assume the following values:

Total Floor Area = 10,000 sq ft
Total Land Area = 5,000 sq ft

Using the formula to calculate the Floor Space Ratio (FSR):

\[ FSR = \frac{\text{Total Floor Area}}{\text{Total Land Area}} = \frac{10,000}{5,000} = 2 \]

The Floor Space Ratio (FSR) is 2.
