Break-even price is the lowest selling price at which a unit neither makes nor loses money. Enter unit cost (purchase, inbound freight, and so on) and percentage fees such as commission and payment charges to back it out. Add a target profit amount if you want a little margin above break-even.
Break-even price = (unit cost + target profit) ÷ (1 − commission − payment − other rates). If the rates add up to 100% or more, no finite price exists.
Divide unit cost by the share of the price you keep. If cost is 80 and commission plus payment fees are 20%, the break-even price is 80 ÷ 0.8 = 100.
Break-even price answers how high the price must be. Break-even ROAS answers how much ad return you need. The formulas differ; the pages can be used together.
With a target profit, the result is the price that earns that profit, not a zero-profit break-even. The page also shows contribution after percentage fees.
