Interior Cost Calculated

One of the most common questions homeowners ask is: “How is interior cost calculated?” The answer depends on the size of the property, quality of materials, labor charges, and customization. If you’re planning a home in Delhi NCR, Gurgaon, or Noida, understanding how designers and contractors calculate cost will help you plan your budget more effectively.


Key Methods of Calculating Interior Costs

1. Per Square Foot Rate

This is the most common method in India.

  • Range: ₹800 to ₹2,500+ per sq. ft.

  • Factors: material quality, finishes, and complexity.

  • Example: For a 1,500 sq. ft. apartment in Noida at ₹1,200 per sq. ft., cost = ₹18,00,000 approx.

2. Item-Based Costing

Here, each component is calculated individually.

  • Wardrobes, kitchen units, false ceilings, furniture, lighting, and décor are priced separately.

  • Gives flexibility to add/remove items based on budget.

3. Percentage of Property Value

Some premium firms charge a percentage of the property value.

  • Usually 7–15% of property cost.

  • More common in luxury projects and villas in Gurgaon or Delhi.


Major Factors Affecting Interior Costs

  1. Size of the Property
    Larger homes mean higher material and labor requirements.

  2. Quality of Materials

    • Laminates vs. solid wood.

    • Regular tiles vs. imported marble.

    • Basic paint vs. luxury wall finishes.

  3. Customization Level
    Modular furniture is cheaper than fully customized carpentry.

  4. Labor Charges
    Skilled craftsmen and metropolitan labor rates increase costs.

  5. Design Fees
    Interior designers typically charge 10–15% of project cost or a fixed design fee.

  6. Location
    Interiors in Delhi NCR or Mumbai cost 20–40% more than in Tier-2 cities due to labor, logistics, and material availability.

Tips to Control Interior Costs

  • Finalize a budget before starting.

  • Compare modular vs. customized furniture.
