Professional Guide to Calculating E-Commerce Net Profit & Margins
In online retail, achieving high revenue is only half the battle. True business sustainability depends on your Net Profit and Profit Margin. This interactive calculator is designed specifically for online merchants to compute exactly what they pocket after all variable costs are settled.
How Do You Calculate E-Commerce Margin Per Unit?
To determine your product's real financial viability, you must subtract all direct expenses from the retail selling price. These include:
- Product Cost (COGS): The wholesale purchase price of your item, including overseas shipping, customs duties, and packaging.
- Platform & Gateway Fees: The percentage deducted by payment processors (such as Stripe, PayPal, Visa, or Mastercard) and platform subscription/transaction fees.
- Acquisition Ad Cost (CAC): The advertising budget spent on channels like TikTok Ads, Meta Ads, or Google Shopping to acquire a single paying customer.
Benchmarks for E-Commerce Profitability
