Design charge rate₹/sq fte.g. ₹50, ₹100
Material & finishes factormultiplierfactor to account for materials (1.0 = basic, higher for upgrades)
Misc overhead & margin%10 %–20 % buffer

Formula:

Base design cost = Area × Design charge rate
Material cost = Base design cost × (Material factor – 1)
Subtotal = Base design cost + Material cost
Total = Subtotal × (1 + Overhead %)

Worked Example

Say:

  • Area = 200 sq ft
  • Design charge rate = ₹80 / sq ft
  • Material factor = 1.3 (i.e. 30 % extra for materials)
  • Overhead = 15 %

Calculation:

  1. Base design = 200 × 80 = ₹16,000
  2. Material cost = 16,000 × (1.3 – 1) = ₹4,800
  3. Subtotal = 16,000 + 4,800 = ₹20,800
  4. Total = 20,800 × 1.15 = ₹23,920
