Why Accurate Calculations Matter in Ecommerce

In the competitive world of online retail, margins are everything. A miscalculation in your profit margin, advertising spend, or pricing strategy can quickly turn a profitable product into a loss leader. Our calculators are built with the specific needs of ecommerce sellers in mind, accounting for factors like:

  • Cost of Goods Sold (COGS) - Manufacturing, materials, and direct labor costs
  • Transaction Fees - Payment processor fees from Stripe, PayPal, or Shopify Payments
  • Platform Fees - Amazon FBA fees, Etsy transaction fees, and marketplace commissions
  • Shipping Costs - Both inbound freight and outbound customer shipping
  • Customer Acquisition Cost (CAC) - What you spend on ads to acquire each customer
  • Returns & Refunds - The often-overlooked cost of product returns
