Break-Even Analysis
Break-even price (per unit)ⓘ$8.00
Contribution margin per unit$17.00
How this is calculated
Break-even price: (Variable cost + Shipping + Packaging + Payment fixed fee) / (1 − Platform fee rate − Payment fee rate)
Contribution margin: Sale price − Variable cost − Platform fee − Payment fee
Break-even units: Fixed costs / Contribution margin per unit
Assumptions:
- Break-even price: zero profit per unit, no fixed costs
- Break-even units: monthly fixed costs divided by per-unit contribution margin
- Ad spend not included — treat it as a variable cost if relevant
