The fee for interior design isn’t a fixed price — it varies based on scope of work, location, experience of the designer, and whether supervision is included. Below are the most common methods interior designers use to charge and typical ranges you can expect in India (2025–26 standards).
1. Percentage of Total Project Cost (Common Model)
Most professional designers charge a percentage of the total interior execution cost:
- Design only: ~6% – 10%
- Design + site supervision: ~8% – 15%
- Full project management: ~10% – 18%
Example:
If your 3BHK interior execution cost is ₹15 lakh and the designer charges 10%:
👉 Design fee = ₹15,00,000 × 10% = ₹1,50,000
2. Per Square Foot Basis
Many designers charge based on carpet area:
| Service Type | Typical Range (₹ per sq ft) |
|---|---|
| Design only | ₹100 – ₹250/sq ft |
| Design + supervision | ₹200 – ₹400/sq ft |
Example:
2BHK (1,000 sq ft) with design + supervision @ ₹250/sq ft:
👉 ₹1,000 × ₹250 = ₹2,50,000
3. Fixed Lump-Sum Fee
Some designers quote a flat fee regardless of sq ft or project cost.
Typical ranges for whole-home design:
- 2BHK: ₹1.0 – ₹2.5 lakh
- 3BHK: ₹1.5 – ₹3.0 lakh
- Larger homes/villas: ₹3.0 lakh+
This works best when project scope is clearly defined.
4. Room-Wise Fee (Partial Interiors)
For partial work (e.g., living room, kitchen only):
| Room | Typical Range (₹) |
|---|---|
| Living room | ₹30,000 – ₹75,000 |
| Bedroom | ₹25,000 – ₹60,000 |
| Kitchen | ₹40,000 – ₹1,00,000 |
This is often used for small projects or limited scope.
5. Included in Turnkey Package
Some interior firms do not charge a separate design fee. Instead:
- Design cost is built into the execution price
- Total per sq ft quotes include design, modular work, and labour
This is common with national firms or online platforms.
What Design Fees Usually Include
✔ Space planning
✔ Layout drawings
✔ 3D renders (optional tier)
✔ Material & finish selection
✔ Vendor coordination
May NOT include (unless agreed):
- Site supervision
- Procurement
- Civil work drawings
- Custom carpentry fabrication details
How to Evaluate What’s Reasonable
- Percentage model: Best for large, open scope
- Per sq ft model: Transparent and easy to compare
- Fixed fee: Good when scope is fixed up front
- Room-wise: Useful for small or phased work
Quick Examples
- 3BHK Mid-Range Home
- Interior execution cost: ₹15 lakh
- Designer fee @ 10% → ₹1.5 lakh
- 3BHK using per sq ft
- Area: 1,200 sq ft
- Designer charges: ₹200/sq ft
- ₹1,200 × 200 = ₹2,40,000
- 2 Rooms Only
- Living + bedroom only
- Estimated room-wise fee: ₹30,000 + ₹35,000 = ₹65,000
Final Takeaway
A reasonable interior design fee for a full-home project is typically:
- ₹1.5 – ₹3 lakh for a 3BHK
- ₹1 – ₹2 lakh for a 2BHK
- Per sq ft: ₹150 – ₹300/sq ft (design + supervision)
Smaller or partial projects can be much less.
If you share your flat size, city, and whether you want design only or with site supervision, I can calculate a precise fee estimate for your case.
