A five-minute pricing guide
Break-even is a volume question, not just a price
Start with contribution
Selling price is not the amount left to cover fixed cost. First subtract the variable fee, fixed fee per order, and variable cost. The remainder is your unit contribution.
Separate break-even from your goal
Break-even units recover fixed cost. Target-profit units must recover both fixed cost and the profit you want. Round units up because a fraction of a sale cannot complete the plan.
Check the capacity constraint
If the target needs more units than you can make or fulfill, the model is not operationally feasible yet. Revisit price, cost, fees, target, or capacity before relying on the plan.
