Here’s a simple cost calculator framework you can use for low-budget interior design.
Step 1: Choose Scope / Tier
- Design only → ₹50–₹150 per sq ft
- Semi-turnkey (modular furniture + basic finishes) → ₹150–₹300 per sq ft
- Full execution (budget materials) → ₹300–₹500 per sq ft
Step 2: Multiply by Usable Area
Cost = Area (sq ft) × Rate (₹/sq ft)
Step 3: Add Buffer
Add 10–20% buffer for site overhead, material fluctuation, transport, and small extras.
Quick Example
Flat size = 700 sq ft usable
- Design only → 700 × 100 = ₹70,000 (±10–20%)
- Semi-turnkey → 700 × 200 = ₹1,40,000 (±10–20%)
- Full budget execution → 700 × 400 = ₹2,80,000 (±10–20%)
Optional Add-Ons
- Kitchen modular setup → ₹80,000 – ₹1,50,000
- Wardrobes (per unit) → ₹25,000 – ₹50,000
- False ceiling → ₹70 – ₹120 per sq ft
- Paint / wallpaper → ₹15 – ₹40 per sq ft
⚡ If you give me your city / locality and flat area (sq ft or 1BHK / 2BHK / 3BHK), I can run this calculator to produce a custom low-budget estimate for your property. Do you want me to generate that for you?
