How to use this calculator
Contribution margin per unit is the price minus variable cost — the amount each unit sale contributes toward covering fixed costs. Dividing total fixed costs by contribution margin gives the exact units needed to break even.
- 1
Enter all fixed costs that do not change with volume: rent, salaries, insurance, equipment depreciation.
- 2
Enter your selling price per unit and variable cost per unit (materials, packaging, shipping, commissions).
- 3
The break-even units tell you the minimum volume needed to avoid a loss.
- 4
Use this to set monthly sales targets and to evaluate whether your pricing supports a profitable business at realistic volume.
Frequently asked questions
What counts as a variable cost?
Variable costs move directly with production or sales volume. For physical products: raw materials, packaging, direct labour, shipping, and sales commissions. For digital products: payment processing fees and per-seat software costs. Fixed costs (rent, salaries, subscriptions) do not count even if they occasionally change.
How do I use break-even to set my price?
Work backwards: decide on the maximum realistic monthly unit volume, then solve for the price that makes break-even achievable at, say, 70% of that volume. This leaves a safety margin. If no price achieves break-even at realistic volume, you need to reduce fixed or variable costs.
What if I have multiple products?
Multi-product break-even requires a weighted-average contribution margin based on your expected sales mix. Calculate contribution margin per unit for each product, weight by expected volume share, and divide fixed costs by the weighted average. Most accounting software can do this automatically.
Is break-even the same as profitability?
No — break-even is the point of zero profit and zero loss. Profitability requires selling above break-even. The safety margin is how far your actual sales exceed break-even: (Actual Units − Breakeven Units) / Actual Units × 100. A 30% safety margin means you could lose 30% of sales before hitting a loss.

Why Break-Even Analysis Is the Foundation of Product Pricing
Before launching any product, you should know exactly how many units must sell each month to cover costs. If your break-even is 5,000 units and your market research suggests a realistic addressable volume of 2,000 units, the product cannot work at that price-cost combination — and you need to know this before investing in inventory, marketing, or operations. Break-even analysis is the first filter every product decision should pass through.
Contribution Margin: The Metric That Explains Business Viability
Contribution margin per unit ($31 in the example above) is the amount each sale contributes to covering overhead. A product with a $5 contribution margin needs 6,000 sales to cover $30,000 in fixed costs. A product with a $30 contribution margin needs only 1,000 sales. This is why high-margin products are so valuable: they reach break-even faster and turn profitable at lower volumes. When evaluating products, compare contribution margin ratios rather than absolute prices — a $49 product with 63% CM ratio outperforms a $200 product with 15% CM ratio at the same fixed cost base.
