Primark Price Calculator

A specialized web application designed for calculating packaging carton prices for Primark. This tool streamlines the cost estimation process by factoring in manufacturing origins, material specifications, and dynamic fee structures.

Features

📦 Carton Configuration

• Manufacturer Origin: Select from verified production regions (e.g., Bangladesh, India, China).
• Material Selection: Choose specific Flute Types (C32, C40, BC40) based on origin capabilities.
• Carton Styles: Toggle between "Standard Footprint" (pre-defined sizes) and "Custom Footprint" (flexible dimensions).

💰 Intelligent Pricing Engine

• Dynamic Calculations: Automatically computes Unit Price, Total Area, and Total Price.
• Fee Structure:
  • Program Management Fee: Automatically applied at 5% (calculated from Total Price).
  • Rebates: Configurable rebate logic for Primark.
  • SQM Pricing: Base price set to $0.85 per m² for custom dimensions.
• SQM Formula: Uses flute-specific trim formulas with 8% wastage.

🧮 SQM Calculation Formula

The application uses specific formulas based on Flute Type:

For C Flute (C32, C40):

• Sheet Length (L): 2 × (Length + Width) + 15 (mm)
• Sheet Width (W): (Width + Height) - 10 (mm)

For BC Flute (BC40):

• Sheet Length (L): 2 × (Length + Width) + 11 (mm)
• Sheet Width (W): (Height + Width) - 16 (mm)

Area Calculation (All Types): ((L × W) / 1,000,000) × 1.08 (Includes 8% Wastage)
