What Is a Break-Even Price?
Your break-even price is the minimum amount you can sell a product for without losing money — the point where revenue exactly covers every cost involved in getting that sale: the product's cost of goods (COGS), the platform's selling fee, shipping, and any advertising spend attributed to that sale. Price below it and every sale actively loses money, no matter how much volume you move. This calculator adds up all four cost components and works backward to show you the exact floor price, plus what price you'd need to hit a specific target margin above that floor.
Why Sellers Underestimate Their True Break-Even
The most common pricing mistake online sellers make is pricing based only on product cost and platform fee, forgetting that shipping and ad spend are just as real a cost per unit — especially on platforms where advertising is effectively mandatory to get visibility. A product that looks profitable on a simple cost-plus-fee calculation can quietly be a loss-maker once realistic shipping and ACOS (advertising cost of sale) are factored in. This tool's profit curve view shows exactly how margin changes as you adjust price, so you can see the real trade-off before setting your listing price.
