Instead of asking "how many units to break even?" — sometimes you need to ask "what price do I need to charge to break even at my expected sales volume?" This is reverse break-even analysis.
Reverse break-even formula
Minimum price = (Fixed costs ÷ Expected units) + Variable cost per unit
Example: $6,000 fixed monthly costs, expect to sell 200 units, $8 variable cost:
- Minimum price = ($6,000 ÷ 200) + $8 = $30 + $8 = $38/unit
At $38, you cover costs exactly (zero profit). Add your target margin on top:
- For 20% profit margin: price = $38 ÷ (1 − 0.20) = $47.50
- For 30% profit margin: price = $38 ÷ (1 − 0.30) = $54.30
Why this matters for product pricing
Many founders choose prices based on competitor benchmarks without checking whether those prices are actually profitable given their cost structure. If your costs are higher than competitors' (smaller production runs, higher shipping costs, premium materials), you need to either find a price-justified positioning or reduce costs.
Use the Break-Even Calculator to model different price points, and cross-check with the Profit Margin Calculator to see net margin at each price.
