How the Construction Cost Calculator Works
The calculator turns three inputs — built-up area, number of floors and package — plus your parking and balcony requirement into an indicative turnkey construction cost for Bangalore. It uses the same per sq.ft rates as our packages (₹1,659–₹2,549, GST included) and the same area logic our engineers use for a first estimate.
- Site details: plot area (minimum 500 sq.ft), site type, number of floors (G to G+5), balcony count and parking (cars and bikes).
- Package: pick Value, Dream, Premium or Legacy Home — each carries a different per sq.ft rate.
- Contact details: so an engineer can send the detailed, floor-wise breakdown and answer questions.
You get an approximate total per package and a floor-by-floor split of primary and secondary (parking / balcony / staircase) area cost.

How Built-up Area Is Calculated
As a planning rule the calculator takes built-up area per floor ≈ plot area × 0.80. On a 30×40 plot (1,200 sq.ft) that is about 960 sq.ft per floor. Your actual built-up area comes from the approved floor plan after setbacks and FAR/FSI, and can be a little higher or lower.
| Plot Size | Approx. Built-up / Floor | G+1 Total | G+2 Total |
|---|---|---|---|
| 20 × 30 (600 sq.ft) | ~480 sq.ft | ~960 sq.ft | ~1,440 sq.ft |
| 30 × 40 (1,200 sq.ft) | ~960 sq.ft | ~1,920 sq.ft | ~2,880 sq.ft |
| 30 × 50 (1,500 sq.ft) | ~1,200 sq.ft | ~2,400 sq.ft | ~3,600 sq.ft |
| 40 × 60 (2,400 sq.ft) | ~1,920 sq.ft | ~3,840 sq.ft | ~5,760 sq.ft |
The Cost Formula
| Built-up area / floor | Plot area × 0.80 |
| Primary area cost | Primary built-up area × package rate |
| Secondary area cost | (car parking + bike parking + balcony + external stair) × (package rate × 0.80) |
| Parking allowance | 180 sq.ft per car, 40 sq.ft per bike |
| Balcony / external stair | 80 sq.ft each |
| Total | Σ (primary cost + secondary cost) across all floors |
Secondary areas — open parking, balconies and an external staircase — are billed at about 80% of the package rate because they need less finishing than living space. A full worked example is on the construction cost in Bangalore page.

Why Your Actual Quotation May Differ
The calculator gives a civil-construction planning number. A firm quotation is prepared after reviewing the approved drawing, setbacks, soil report and material choices, and will differ because of:
- Actual built-up area from the sanctioned plan (vs the 80% planning rule)
- Soil condition — soft soil, rock or water changes foundation cost
- Number of bathrooms, kitchens and electrical / plumbing points
- Elevation design beyond basic plaster and paint
- Material upgrades above the package value caps
- Approvals, compound wall, borewell, BESCOM / BWSSB, rainwater harvesting
What the Estimate Does Not Include
The calculator estimates civil construction only. Quoted separately: BBMP / BDA / BMRDA / Panchayat approval and betterment charges, compound wall and gate, borewell, BESCOM and BWSSB connection works, rainwater harvesting, lift, solar, premium elevation cladding, and interiors (modular kitchen, wardrobes, false ceiling, furniture). See what is included vs excluded.
