Formula
Floor Area = Length × Width
Wall Area = Perimeter × Height
Material Cost = Framing + Insulation + Drywall + Flooring + Windows + Electrical + Plumbing + Bathroom + Paint
Total Cost = Material Cost + Labor + Permits
Example: 30 ft × 20 ft basement, 8 ft ceiling, full finishing with bathroom
Step 1: Floor area = 30 × 20 = 600 sq ft
Step 2: Perimeter = 2 × (30 + 20) = 100 ft
Step 3: Wall area = 100 × 8 = 800 sq ft
Step 4: Framing = 800 × $4 = $3,200
Step 5: Insulation = (800 + 600) × $3 = $4,200
Step 6: Drywall = (800 + 600) × $1.50 = $2,100
Step 7: Flooring = 600 × $5 = $3,000
Step 8: Electrical = 600 × $5 = $3,000
Step 9: Plumbing = 600 × $8 + $3,000 = $7,800
Step 10: Bathroom = $8,000
Step 11: Paint = 1,400 × $0.50 = $700
Step 12: Material total = $3,200 + $4,200 + $2,100 + $3,000 + $3,000 + $7,800 + $8,000 + $700 = $32,000
Step 13: Labor = 600 × $12 = $7,200
Step 14: Permits = $1,000
Step 15: Total = $32,000 + $7,200 + $1,000 = $40,200
Step 16: Cost per sq ft = $40,200 / 600 = $67/sq ft
