About this calculator
The 4 BHK Interior Cost Calculator estimates turnkey interior cost for large apartments and small villas across India. The 2026 India range for a 4 BHK (1800–2500 sqft) is ₹12–28 lakh for a premium build with modular kitchen, 4 wardrobes, false ceiling and paint. Luxury PU + imported hardware projects push past ₹50 lakh.
4 BHK interiors carry a steeper per-sqft rate than 2/3 BHK because the rooms are bigger, the wardrobe count rises to 4–5, and most 4 BHK buyers expect premium finishes throughout. The calculator includes a dedicated children's wardrobe count, a study/home office add-on and a pooja unit line.

How the calculation works
Base ₹12–22 lakh for 2000 sqft premium, scaled by carpet area, tier (budget 0.8×, premium 1×, luxury 1.9×) and city index. A 2000 sqft 4 BHK premium in Bengaluru lands at ₹14–18 lakh; in Mumbai with luxury PU, ₹26–32 lakh. Each extra wardrobe is ₹85k–1.4 lakh; study room ₹1.2–3 lakh.
Why this estimate is more accurate
Branded firms routinely quote ₹35–60 lakh for 4 BHK without breaking down line items. The realistic baseline is ₹12–28 lakh for everything except luxury PU + imported finishes — knowing this lets you push back on inflated quotes.
