What is a good profit margin for an online store?
Most e-commerce businesses target a net margin of 10–30% per sale. Margins below 10% are tight and leave little room for marketing spend or returns.
Platform fees and payment processing are the two variables most sellers overlook. Switching from a 2% transaction fee platform to a 0.75% platform on $20,000/mo GMV saves over $250/month — pure margin.
This calculator accounts for: product cost, shipping, Stripe processing (1.6% + $0.30), and platform-specific transaction fees.
