• PTR (Price To Retailer): This is the rate at which the medical retailer purchases medicine from the stockist or distributor. The formula to calculate PTR is:
  PTR = (MRP - (MRP * (Retail Margin / 100))) / (1 + (GST / 100))

• PTS (Price To Stockist): This is the rate at which the stockist purchases medicine from the pharma company. The formula to calculate PTS is:
  PTS = PTR - (PTR * (Stockist Margin / 100))

Retail Margin and Stockist Margin are the profit percentages that retailers and stockists respectively earn on the sale of pharmaceutical products. Understanding these margins is pivotal for sustaining and growing your business.

• Retail Margin: This is the percentage of profit that a retailer makes on selling the product to the end consumer. It is calculated as:
  Retail Margin = ((MRP - PTR) / MRP) * 100
• Stockist Margin: This is the percentage of profit that a stockist makes on selling the product to the retailer. It is calculated as:
  Stockist Margin = ((PTR - PTS) / PTR) * 100
