How to Calculate Interior Design Fees?

The cost of hiring an interior designer depends on several factors, including the scope of work, experience, project size, and design complexity. Here are the most common methods used to calculate interior design fees in India:

1. Per Square Foot Basis

Formula:
👉 Interior Design Cost = Area (sq. ft.) × Rate per sq. ft.

✅ Best for: Full home interiors (3 BHK, 2 BHK, Villas)

Cost Range:

• Basic Design: ₹50 – ₹150 per sq. ft.
• Mid-Range Design: ₹150 – ₹500 per sq. ft.
• Luxury Design: ₹500 – ₹2,000 per sq. ft.

🔹 Example Calculation for a 3BHK (1,200 sq. ft.):

• Basic Interior: ₹60 × 1,200 = ₹7.2 Lakh
• Premium Interior: ₹300 × 1,200 = ₹36 Lakh

2. Percentage of Total Project Cost

Formula:
👉 Interior Design Fees = X% of Total Project Cost

✅ Best for: High-end projects, commercial interiors

Typical Range:

• 5% – 10% for Budget Projects
• 10% – 15% for Mid-Range Designs
• 15% – 25% for Luxury Interiors

🔹 Example Calculation:
If your total project cost is ₹15 Lakh, and the designer charges 10%, the fee will be:
👉 ₹15 Lakh × 10% = ₹1.5 Lakh

3. Flat Fee / Lump Sum Charge

✅ Best for: Small projects, consultations, single-room designs

• Designers charge a fixed amount based on the work scope.
• Fees range from ₹50,000 to ₹5 Lakh, depending on project complexity.
• Example: A modular kitchen redesign may cost ₹1 Lakh – ₹3 Lakh.

4. Hourly Basis

✅ Best for: Consultation, small projects, or on-demand services

Average Rates:

• Beginner Designers: ₹500 – ₹1,500 per hour
• Mid-Level Designers: ₹1,500 – ₹5,000 per hour
• Top Professionals: ₹5,000 – ₹15,000 per hour

🔹 Example Calculation:
If a designer spends 20 hours on a project at ₹2,000 per hour, the fee is:
👉 ₹2,000 × 20 = ₹40,000

5. Cost-Based on Scope (Package Model)

✅ Best for: Home interiors (1BHK, 2BHK, 3BHK), turnkey solutions
