What is a break-even calculator?

A break-even calculator tells you exactly how many units you need to sell — or how much revenue you need to earn — before your business covers all its costs and starts making a profit. It uses three inputs: fixed costs, price per unit, and variable cost per unit.

What are fixed vs variable costs?

Fixed costs don't change with sales volume (rent, salaries, software subscriptions). Variable costs scale with production (materials, shipping, payment processing fees). Knowing the difference is the foundation of any break-even analysis.

How do I do a break-even analysis?

Break-even analysis compares your total costs to your total revenue at different sales volumes. The break-even point is the volume where they cross. Once you know it, you can set realistic sales targets, decide whether a product is worth launching, and stress-test your pricing.

What is the break-even point formula?

Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). The denominator is your contribution margin — how much each sale contributes toward covering fixed costs. Break-Even Revenue = Break-Even Units × Price per Unit.

What is contribution margin and why does it matter?

Contribution margin is the selling price minus the variable cost per unit. It represents how much each sale "contributes" toward covering fixed costs. For example, if you sell a product for $99 with $35 variable cost, your contribution margin is $64. You need to sell enough units at $64 each to cover your total fixed costs before you make any profit.

What if my price is lower than my variable cost?

If price ≤ variable cost, you lose money on every sale — there is no break-even point. You must either raise your price or reduce your variable cost per unit before the business can ever be profitable.

How can I lower my break-even point?

Three levers: (1) Reduce fixed costs — cut overhead like rent, subscriptions, or headcount. (2) Raise your price — even a small price increase significantly lowers break-even units. (3) Lower variable costs — negotiate with suppliers or streamline production. Raising price is often the fastest lever.

Quelle est la différence entre coûts fixes et variables ?
