What is the break-even point in ecommerce?

The break-even point is the number of units or dollar amount of revenue at which your total costs equal your total revenue, resulting in $0 profit. Below the BEP, you lose money. Above it, you generate profit. For ecommerce, it's calculated as Fixed Costs ÷ (Selling Price – Variable Cost per Unit).

How do fixed and variable costs differ for ecommerce?

Fixed costs don't change with sales volume — rent, software subscriptions, base ad budgets, salaries. Variable costs scale with every sale — COGS, packaging, shipping, payment processing. Knowing your split is essential because it tells you exactly how much each sale contributes to covering your fixed costs and generating profit.

Does break-even change over time?

Yes — your break-even point will shift whenever your costs or prices change. If you raise prices, BEP drops. If your supplier raises COGS, BEP rises. If you add a new subscription tool (higher fixed costs), BEP rises. Review your BEP quarterly or whenever you make a significant change to pricing or cost structure.

Is break-even the same as profitable?

No — breaking even means you're covering your costs, not making profit. True profitability requires revenue that exceeds all costs including your break-even point. Think of break-even as the starting line, not the finish line. The goal is to push well above your BEP into healthy profit margins.

How do I calculate BEP for multiple products?

For multiple products, use the weighted average contribution margin — calculate the total contribution from all products divided by total units sold. Or use the BEP revenue formula: Fixed Costs ÷ Overall Gross Margin Percentage. Use our Break-Even Calculator to model multi-product scenarios with different pricing and cost structures.

★ Quick Answer

Your ecommerce break-even point is when Total Revenue = Total Costs. For a typical ecommerce store, this means covering: product costs + Amazon/FBA fees (15–40%) + advertising spend + platform fees + shipping. A Shopify store with $50 AOV and $5 cost of goods typically needs to sell approximately 100–200 units monthly to break even at a $500/month ad spend level. Use our Break-Even Calculator to find your exact number.
