Here’s a “cheap / low-budget interior design cost estimate” framework + benchmark numbers to help you approximate.
Benchmark Data (India)
- Designers and decorators often quote ₹50 to ₹500 per sq. ft. depending on city, scope, finishes. (The Architects Diary)
- In Chennai, for modest rooms, design rates are around ₹100–₹250 per sq. ft. (CHENNAI HOME DECOR)
- Some interior design rate guides suggest very low base design services can be in range ₹8 to ₹90 per sq. ft. for minimal scope / small rooms. (dsigndpo.com)
- For a typical living room, basic furnishing + design may cost ₹20,000 – ₹50,000 depending on size and city. (DesignCafe)
Estimate Framework
Use this approach to approximate:
- Area to work on (sq ft)
- Base design charge rate (₹ per sq ft) for low budget
- Material & execution multiplier (for finishes, furniture, lighting)
- Buffer / overhead (10-20%)
Formula:
Base design cost = Area × Design rate
Material & execution cost = Base × (multiplier – 1)
Total = (Base + Material cost) × (1 + overhead%)
Sample Estimate
Suppose a small apartment / room of 600 sq ft, with low-budget scope:
- Choose a design rate: ₹100 / sq ft → Base = ₹60,000
- Multiplier for execution: 1.3 (30% extra) → Material/ execution = ₹18,000
- Overhead buffer: 15% → adds ~ ₹11,700
Total ≈ ₹89,700
If you scale down scope or quality, you might aim for ₹50 / sq ft base, bringing total to ~ ₹45,000–₹60,000 range for 600 sq ft.
If you tell me your city / locality and area (sq ft or dimensions) and what “cheap” means to you (furnishings / just design / partial execution), I can run a custom estimate for your case. Do you want me to do that?
