A realistic budget for interior design isn’t a fixed number—it depends on your home size, desired quality, scope of work, and location. Below is a practical, real-world breakdown that most homeowners actually spend when designing a home.
🧠 Key Guideline: Budget Depends on Scope
Before looking at numbers, understand the three main budget components:
- Design fees (planning, layouts, 3D visuals)
- Execution & furniture costs (modular work, carpentry, décor)
- Finishes & materials (paint, lighting, tiles, fixtures)
📊 Realistic Budgets by Home Size (India)
🏠 1. 1BHK (700–900 sq ft)
- Basic Interiors: ₹3 L – ₹5 L
- Mid-Range: ₹6 L – ₹8 L
- Premium: ₹10 L – ₹15 L+
🏠 2BHK (900–1,200 sq ft)
- Basic Interiors: ₹5 L – ₹8 L
- Mid-Range: ₹8 L – ₹12 L
- Premium: ₹15 L – ₹25 L+
🏠 3BHK (1,100–1,500 sq ft) — Most Common
- Basic / Budget: ₹7 L – ₹10 L
- Realistic Mid-Range: ₹12 L – ₹18 L
- Good Quality / Premium: ₹20 L – ₹30 L+
👉 Most homeowners spend around ₹12 L – ₹18 L for a well-coordinated 3BHK interior that includes modular elements, good finishes, lighting, and furniture.
📐 Realistic Per Sq Ft Reference
Interior designers often price work on a per square foot basis:
- Budget: ₹800 – ₹1,200 / sq ft
- Mid-Range: ₹1,500 – ₹2,500 / sq ft
- Premium: ₹3,000+ / sq ft
For a 3BHK (~1,200 sq ft), this translates approximately to:
- Budget: ₹9.6 L – ₹14.4 L
- Mid-Range: ₹18 L – ₹30 L
- Premium: ₹36 L+
So the ₹12 L – ₹18 L range aligns with the mid-range average most homeowners choose.
