Break-even and profit results
How the break-even point is calculated
Contribution margin per unit is selling price − variable cost per unit. Break-even units equal fixed costs ÷ contribution margin per unit, rounded up to the next whole unit so the result fully covers costs.
Expected profit equals expected units multiplied by contribution margin, minus fixed costs. Margin of safety shows how far expected sales are above or below the exact break-even point.
Classify costs consistently. Rent and recurring salaries are often fixed for a period, while materials, packaging and transaction fees may change with each unit. This tool is a planning estimate, not accounting, tax or financial advice.
