Frequently Asked Questions

What is FSI vs FAR?

FSI (Floor Space Index) and FAR (Floor Area Ratio) mean the same thing in India — built-up area divided by plot area.

Does this cover all Indian cities?

FSI limits vary by city development plan. Use this for preliminary estimates — confirm with your municipal corporation.

What is ground coverage?

The percentage of plot area that can be built on the ground floor. Used to estimate number of floors.

Is TDR or premium FSI included?

No — this calculator uses the base FSI you enter. Additional FSI from TDR or paid premium must be added manually.
