To calculate interior cost in a realistic way, break it into measurable components. Most professionals use a per sq. ft. method, plus itemized costs for modular furniture, décor, and civil work.
Step 1: Identify Your Built-Up Area
- Measure total sq. ft. of your property (e.g., 1,200 sq. ft. for a 2BHK).
- Interior costs are usually calculated on this base.
Step 2: Choose Your Finish Level
Approximate cost per sq. ft. in Gurgaon / Noida / Delhi NCR:
- Basic: ₹1,200–₹1,800 per sq. ft.
- Mid-range: ₹2,000–₹3,000 per sq. ft.
- Premium / Luxury: ₹3,500+ per sq. ft.
Multiply area × rate to get an estimate.
Example: 1,200 sq. ft. × ₹2,000 per sq. ft. = ₹24,00,000 (mid-range).
Step 3: Break Down Major Cost Components
- Modular Kitchen
- Basic: ₹1.5–₹3 lakhs
- Premium: ₹4–₹8 lakhs
- Wardrobes (per room)
- Basic: ₹70,000–₹1.5 lakhs
- Premium: ₹2–₹4 lakhs
- False Ceiling
- ₹120–₹200 per sq. ft.
- Flooring / Wooden Flooring
- Tiles: ₹80–₹150 per sq. ft.
- Premium wood: ₹250–₹600 per sq. ft.
- Painting / Wallpaper
- ₹12–₹30 per sq. ft.
- Furniture (beds, sofa, dining, tables)
- ₹2–₹10 lakhs depending on customization.
- Lighting & Electricals
- ₹1–₹3 lakhs average for a 2/3BHK.
Step 4: Add Professional Fees
- Designers may charge 5–20% of project cost OR
- A fixed fee of ₹40–₹200 per sq. ft.
Step 5: Add a Buffer
Always add 10–15% buffer for price fluctuations, last-minute changes, or upgrades.
✅ Quick Formula
Interior Cost = (Total Area × Cost per sq. ft.) + Furniture + Décor + Designer Fees + Buffer
