About this calculator
The 3 BHK Interior Cost Calculator is built for India's fastest-growing home segment — the 1100–1800 sq ft 3 BHK in metro and tier-2 cities. The 2026 turnkey range for a 3 BHK premium interior is ₹8–18 lakh; luxury builds with PU finishes and imported veneers can push past ₹30 lakh. This calculator lets you model the trade-offs and download a PDF you can share with your spouse, designer or home-loan officer.
A 3 BHK interior typically includes a 10–14 Rft modular kitchen, three wardrobes (one usually bigger for the master bedroom), false ceiling across living and bedrooms, a study or pooja space, painting, electrical upgrades and a TV unit or dado wall. Most 3 BHK homeowners also add smart-home conduit, MCB upgrades and extended warranties — small line items that add up to ₹50k–1.5 lakh on top.

How the calculation works
For a 3 BHK, we start from ₹8–15 lakh — the realistic 2026 premium base for ~1400 sq ft in Bengaluru. The same four-step math applies: tier multiplier, area scaling, city index, module toggles. Adding a fourth wardrobe shifts the total by ~5%; switching from laminate to acrylic kitchen finish typically adds ₹1–1.5 lakh; PU finish across kitchen and wardrobes can double the finish-related cost.
Why this estimate is more accurate
3 BHK homeowners face the biggest negotiation surface — the bills are large, the choices are many, and every brand pitches different "packages". Anchoring on a realistic range means you can evaluate three quotes side by side instead of taking the lowest one and discovering scope creep in month two.
Material comparison
| Tier | Kitchen | Wardrobes | Typical 3 BHK total |
|---|---|---|---|
| Budget | Laminate, MDF | Hinged laminate | ₹6.5–10 lakh |
| Premium | Acrylic / laminate, BWP | Sliding acrylic / membrane | ₹9–15 lakh |
| Luxury | PU / lacquered glass | PU / veneer with profile lighting | ₹17–28 lakh |
What affects the final cost

- Kitchen island — adds ₹2–4 lakh including countertop, electricals and seating.

- Imported hardware — Blum / Hettich premium ranges add 8–12% to cabinetry.

- GST — 18% on modular work, quoted separately.
