How does the calculator work?

1. Commission (%)
• Calculation: Selling Price × (Commission % / 100)
• Explanation: Commission is charged on the selling price.
  Example: Selling Price ₹1000, Commission 15% → commission = ₹150
2. GST (%)
• Calculation: (Commission + Closing Fee + Shipping Fee) × (GST % / 100)
• Explanation: GST is calculated on the sum of commission, closing fee, and shipping fee.
  Example: commission ₹150, closing fee ₹20, shipping fee ₹80, GST 12% → gst = ₹30
3. Ads/Promotions (%)
• Calculation: Selling Price × (Promotions % / 100)
• Explanation: Promotions cost is a percentage of selling price.
  Example: Selling Price ₹1000, Promotions 2% → promo = ₹20
4. Return (%)
• Calculation: Selling Price × (Return % / 100)
• Explanation: Return loss is calculated as a percentage of selling price.
  Example: Selling Price ₹1000, Return 10% → returnLoss = ₹100
5. Total Cost
• Calculation: Base Price + Commission + Closing Fee + Shipping Fee + Packaging + GST + Ads + Promotions
6. Net Profit
• Calculation: Selling Price - Total Cost - Return Loss
