Question 1

How accurate is this construction cost calculator?

Accepted Answer

The calculator gives indicative estimates based on current market rates for each state (2026 data). Actual costs vary by soil type, design complexity, contractor, and local material prices. We recommend getting a formal quote from a verified civil engineer on Balaji Builds for a precise estimate.

Question 2

What is the construction cost per sq ft in India in 2026?

Accepted Answer

Construction costs in India in 2026 range from ₹1,200–₹2,200 per sq ft for economy grade, ₹1,700–₹3,200 for standard, and ₹2,500–₹6,000+ for premium construction. Costs vary significantly by state — Maharashtra and Kerala are higher, while UP and Rajasthan are lower.

Question 3

Does the estimate include interior design and furniture?

Accepted Answer

No. The estimate covers civil construction: foundation, structure, brickwork, flooring, doors, windows, electrical wiring, plumbing, and painting. Interior furniture, landscaping, and site development are excluded and typically add 20–40% to the total cost.

Question 4

How much does an additional floor add to construction cost?

Accepted Answer

Each additional floor typically costs 85–95% of the ground floor rate, since the foundation and roof are already accounted for. For example, if your ground floor costs ₹20 lakhs, a first floor would typically add ₹17–19 lakhs.
