FAR Calculator
What is Floor Area Ratio (FAR)?
Floor Area Ratio (FAR) is a key real estate and urban planning metric that determines how much building space you can construct on a piece of land. It is the ratio of a building’s total floor area to the size of the plot on which it is built.
A higher FAR means more construction is allowed, while a lower FAR restricts building density.
FAR Formula Explained
The formula used in the calculator is:FAR=Plot AreaTotal Floor Area
- Total Floor Area: Sum of all floors in the building
- Plot Area: Total land size
Example Calculation
| Parameter | Value |
|---|---|
| Plot Area | 2,000 sq ft |
| Total Floor Area | 4,000 sq ft |
| FAR | 2.0 |
This means the building area is twice the land size.
Why FAR Matters
1. Zoning Compliance
Local authorities regulate FAR to control urban density and infrastructure load.
2. Investment Planning
Real estate investors use FAR to estimate development potential and ROI.
3. Urban Development
Helps maintain balanced city growth, avoiding overcrowding.
Types of FAR
1. Base FAR
Standard ratio allowed without bonuses.
2. Maximum FAR
Upper limit including incentives like green building credits.
3. Premium FAR
Additional FAR available by paying fees to authorities.
Tips to Maximize FAR
- Optimize building design with multi-story layouts
- Utilize basements where allowed
- Check local zoning laws for bonuses
- Consider mixed-use developments

FAQ – Floor Area Ratio Calculator
What is a good FAR value?
It depends on location. Urban areas typically allow higher FAR compared to suburban zones.
Does parking count in FAR?
In many regions, parking areas (especially basements) may be excluded—but this varies.
Can FAR be increased?
Yes, through incentives, zoning bonuses, or purchasing development rights.
Is FAR the same as FSI?
Yes, Floor Area Ratio (FAR) and Floor Space Index (FSI) are essentially the same concept.
