To calculate interior cost for your home, office, or a single room (like a bedroom or kitchen), you need to break down the expenses into key components. This gives you a clear idea of how much you’ll spend and where your money goes.
Here’s a complete guide on how to calculate interior cost in India, especially in Delhi, Gurgaon, and Noida:
🧮 Step-by-Step Guide: How to Calculate Interior Cost
✅ 1. Measure the Area (in Sq. Ft.)
Start with the built-up or carpet area of your home or room.
Example: For a 2BHK with 900 sq. ft. of carpet area, you’ll base most calculations on this number.
✅ 2. Decide the Scope of Work
Are you looking for:
- Design-only consultation?
- Modular furniture installation?
- Full turnkey interiors (design + execution)?
Your choice drastically affects the budget.
✅ 3. Estimate Cost Per Square Foot (Based on Scope)
| Interior Type | Basic (₹/sq. ft.) | Mid-Range | Premium |
|---|---|---|---|
| Design Only | ₹15 – ₹150 | – | – |
| Modular Work Only | ₹800 – ₹1,200 | ₹1,200 – ₹1,800 | ₹2,000+ |
| Full Turnkey Interior | ₹1,000 – ₹1,400 | ₹1,500 – ₹2,200 | ₹2,500 – ₹3,500+ |
💡 Multiply per sq. ft. cost by total area to get an estimate.
✅ 4. Break Down Interior Elements
Break your budget into categories:
| Component | Typical Share (%) | Cost Calculation |
|---|---|---|
| Modular Furniture | 35% – 40% | ₹50,000 – ₹2,00,000+ depending on size |
| Civil Work | 10% – 20% | Wall breaks, flooring, false ceiling |
| Electrical & Lighting | 10% | Panels, LEDs, ambient lighting |
| Wall Treatments | 10% – 15% | Paint, wallpaper, wall panels |
| Soft Furnishing | 5% – 10% | Curtains, rugs, bedding, cushions |
| Decor & Accessories | 5% | Wall art, lamps, mirrors, etc. |
| Design Fees | 5% – 15% | Fixed, hourly or % of total cost |
✅ 5. Use a Budget Formula
💡 Interior Cost = Total Area (sq. ft.) × Cost per sq. ft.
🔹 Example Calculation (Turnkey 2BHK in Noida, 900 sq. ft.):
- Chosen quality: Mid-Range
- Rate: ₹1,500 per sq. ft.
- Estimated Cost = 900 × 1,500 = ₹13,50,000
✅ 6. Add Design Charges (if separate)
Designers charge via:
- Per sq. ft.: ₹50 – ₹200
- Percentage of project cost: 6% – 15%
- Flat fee: ₹50,000 – ₹5 lakh
📌 Interior Cost by Project Type (Delhi NCR Average)
| Project | Cost Range (INR) |
|---|---|
| 1BHK Design + Execution | ₹2.5 lakh – ₹5 lakh |
| 2BHK | ₹4 lakh – ₹8 lakh |
| 3BHK | ₹6 lakh – ₹12 lakh+ |
| Modular Kitchen | ₹1 lakh – ₹3 lakh |
