How to Use the Margin Calculator

This margin calculator helps you quickly estimate how much profit may remain when selling a product. Instead of subtracting only product cost from selling price, it is important to include shipping, packaging, advertising, platform fees, and payment fees.

  • Selling price is the price the customer pays for the product.
  • Product cost is the basic cost of sourcing or producing the product.
  • Platform fee rate is the percentage deducted by marketplaces, shopping platforms, or service platforms.
  • Margin rate is the estimated profit ratio based on the selling price.
  • Break-even price is the minimum selling price needed to avoid a loss.
