What break-even means
Break-even is not a recommended selling price. It is the point where the sale stops losing money. If you sell below break-even, the order takes cash out of the business. If you sell at break-even, you have still not paid yourself or created profit for new stock.
The break-even price is still useful because it creates a floor. A seller who knows the floor can accept offers with confidence, reject bad discounts quickly, and avoid clearing stock at a price that creates hidden losses.
The formula removes the portion of every order that will be taken by percentage costs. If the platform and return reserve together take 15 percent, only 85 percent of the order is available to cover fixed costs such as item cost, postage, packaging, and transaction fees.
