Break-Even Calculator
Use this break-even calculator to find how many units you need to sell to cover costs, with contribution margins and profit scenarios.
About Break-Even Calculator
Knowing your break-even point helps you understand the minimum sales volume your business needs to cover all costs. This calculator takes your fixed costs, variable cost per unit, and selling price to show exactly where revenue meets expenses.
How Break-Even Analysis Works
The formula is straightforward: divide your total fixed costs by the contribution margin per unit (selling price minus variable cost). The result is the number of units you need to sell before you start making money. The calculator also shows your contribution margin ratio, which tells you what percentage of each sale goes toward covering fixed costs and profit.
Profit and Loss Scenarios
The scenario table shows your projected profit or loss at various production levels - from 50% to 200% of the break-even point. This makes it easy to see how sensitive your profits are to changes in volume. Use the target profit mode to find out exactly how many units you need to hit a specific earnings goal.
Using the Results
A high break-even point might mean your fixed costs are too heavy or your margins are too thin. Try adjusting the inputs to see how changes in pricing or cost structure affect the break-even point. For a deeper look at your margins, check the Profit Margin Calculator. And if you're evaluating an investment alongside your break-even analysis, the ROI Calculator can help with that side of the equation.

Frequently Asked Questions
What is a break-even point?
The break-even point is the number of units you need to sell so that total revenue equals total costs. Below that number, you're running at a loss. Above it, you're making profit. It's one of the most basic but useful numbers in business planning.
How is the contribution margin calculated?
Contribution margin per unit equals the selling price minus the variable cost per unit. It represents how much each unit sold contributes toward covering fixed costs and generating profit. The contribution margin ratio expresses this as a percentage of the selling price.
What counts as a fixed cost vs a variable cost?
Fixed costs stay the same regardless of how many units you produce - things like rent, insurance, and salaried staff. Variable costs change with production volume, such as raw materials, packaging, and per-unit labour or shipping costs.
Can I use this for service businesses?
Yes. Think of each billable hour or project as a "unit." Your fixed costs might be software subscriptions, office rent, and salaries. The variable cost per unit could be contractor fees or materials per job, and the selling price is what you charge per hour or project.
What does target profit mode do?
Target profit mode lets you enter a specific profit amount you want to achieve. The calculator then tells you how many units you need to sell to cover all your costs and reach that profit goal, going beyond the basic break-even point.
