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, dΓ©cor, 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: βΉ1,200ββΉ1,800 per sq. ft.
- Mid-range: βΉ2,000ββΉ3,000 per sq. ft.
- Premium / Luxury: βΉ3,500+ per sq. ft.
Multiply area Γ rate to get an estimate.
Example: 1,200 sq. ft. Γ βΉ2,000 per sq. ft. = βΉ24,00,000 (mid-range).
Step 3: Break Down Major Cost Components
- Modular Kitchen
- Basic: βΉ1.5ββΉ3 lakhs
- Premium: βΉ4ββΉ8 lakhs
- Wardrobes (per room)
- Basic: βΉ70,000ββΉ1.5 lakhs
- Premium: βΉ2ββΉ4 lakhs
- False Ceiling
- βΉ120ββΉ200 per sq. ft.
- Flooring / Wooden Flooring
- Tiles: βΉ80ββΉ150 per sq. ft.
- Premium wood: βΉ250ββΉ600 per sq. ft.
- Painting / Wallpaper
- βΉ12ββΉ30 per sq. ft.
- Furniture (beds, sofa, dining, tables)
- βΉ2ββΉ10 lakhs depending on customization.
- Lighting & Electricals
- βΉ1ββΉ3 lakhs average for a 2/3BHK.
Step 4: Add Professional Fees
- Designers may charge 5β20% of project cost OR
- A fixed fee of βΉ40ββΉ200 per sq. ft.
Step 5: Add a Buffer
Always add 10β15% buffer for price fluctuations, last-minute changes, or upgrades.
β Quick Formula
Interior Cost = (Total Area Γ Cost per sq. ft.) + Furniture + DΓ©cor + Designer Fees + Buffer
