How do you calculate interior?

If you are planning to design your home or office in Delhi NCR, Gurgaon, or Noida, one of the first questions is: “How do you calculate interior costs?” Interior cost calculation is not a fixed figure—it depends on multiple factors such as property size, materials, labor, and customization. Here’s a practical guide to help you understand the process.


Main Methods of Interior Cost Calculation

1. Per Square Foot Calculation

The most widely used method in India.

  • Standard range: ₹800 – ₹2,500+ per sq. ft.

  • Depends on quality of finishes (basic, premium, luxury).

  • Example: A 1,500 sq. ft. flat in Noida at ₹1,200 per sq. ft. = ₹18,00,000 approx.

2. Item-Based Calculation

Each item is priced separately.

  • Kitchen: ₹2–4 lakhs

  • Wardrobes: ₹3–6 lakhs

  • Lighting & false ceiling: ₹1.5–3 lakhs

  • Furniture: ₹2.5–5 lakhs
    This method gives more flexibility if you want to prioritize certain rooms.

3. Percentage of Property Value

Some premium designers calculate cost as a percentage of property value.

  • 7–15% of property cost.

  • Common in luxury projects in Gurgaon or Delhi.


Factors That Affect Interior Cost

  1. Size of the Property – Bigger area = higher cost.

  2. Material Quality – Laminate vs. veneer, tile vs. marble, basic vs. luxury fittings.

  3. Customization – Modular furniture is cheaper than custom carpentry.

  4. Labor & Craftsmanship – Metropolitan labor rates are higher.

  5. Design Fees – Professional designers may charge 10–15% of total cost.

  6. Location – Costs in Delhi NCR are higher than Tier-2 cities due to demand and logistics.


Sample Cost Calculation for a 3BHK (1,500 sq. ft.)

  • Modular kitchen: ₹2,00,000 – ₹4,00,000

  • Wardrobes: ₹3,00,000 – ₹6,00,000

  • False ceiling & lighting: ₹1,50,000 – ₹3,00,000

  • Furniture: ₹2,50,000 – ₹5,00,000

  • Paint & finishes: ₹1,00,000 – ₹2,50,000

  • Décor & soft furnishings: ₹80,000 – ₹1,50,000

Total Estimate: ₹10 – ₹20 lakhs (standard to premium finishes).


Tips to Calculate Smartly

  • Start with a budget and stick to it.

  • Decide your finish category (basic, premium, luxury).

  • Compare modular vs. custom work.

  • Add a 10–15% buffer for contingencies.

  • Focus on essentials first—kitchen, wardrobes, and lighting.


Summary

Interior cost is calculated using per sq. ft. rates, item-based pricing, or as a percentage of property value. For a standard 3BHK in Delhi NCR, Gurgaon, or Noida, the cost usually ranges from ₹10 lakhs to ₹20 lakhs, depending on materials, customization, and design choices.
