"You can't manage what you can't measure. Know your numbers."

— Peter Drucker

What is a break-even calculator?

A break-even calculator tells you exactly how many units you need to sell — and how much revenue you need to generate — before your business covers all of its costs and starts turning a profit.

The key formula is: Break-Even Units = Fixed Costs ÷ Contribution Margin, where the contribution margin is the selling price minus the variable cost per unit. Every unit sold contributes that amount toward covering your fixed costs.

The target profit field takes this a step further — showing you how many units you need to sell not just to break even, but to reach a specific profit goal.

lightbulb Example Break-Even Scenario

Suppose you sell a product for $50 per unit, with $20 in variable costs per unit and $9,000 in monthly fixed costs. Your contribution margin is $30 per unit, and your break-even point is 300 units — or $15,000 in monthly revenue.

If you set a target profit of $3,000, you would need to sell 400 units to reach that goal — just 100 more than the break-even point.

Adjusting your selling price or reducing variable costs can dramatically lower your break-even point. Use the calculator above to test different pricing and cost scenarios.

Many business owners use a break-even calculator to set pricing, evaluate new products, and determine minimum sales targets before launching.

Break-Even Calculator FAQs

What is a break-even point?

The break-even point is the level of sales at which total revenue equals total costs — meaning there is no profit and no loss. Any sales above this point generate profit; any sales below it result in a loss.

What is contribution margin?

Contribution margin is the selling price per unit minus the variable cost per unit. It represents how much each unit sold contributes toward covering your fixed costs. Once fixed costs are fully covered, the contribution margin becomes profit.

How can I lower my break-even point?

You can lower your break-even point by increasing your selling price, reducing variable costs per unit, or reducing your total fixed costs. Even small improvements in any of these areas can meaningfully reduce the number of units you need to sell to become profitable.

What is the difference between fixed and variable costs?

Fixed costs stay the same regardless of how much you produce or sell — such as rent, salaries, and insurance. Variable costs change with production volume — such as materials, packaging, and direct labor. Understanding both is essential to an accurate break-even analysis.

Break-even terminology

Fixed Costs

Costs that do not change with production or sales volume — such as rent, salaries, insurance, and equipment leases.

Variable Costs

Costs that increase with each unit produced or sold — such as raw materials, packaging, direct labor, and shipping.

Contribution Margin

Selling price minus variable cost per unit. Each unit sold contributes this amount toward covering fixed costs — and becomes profit once fixed costs are fully recovered.

Contribution Margin Ratio

Contribution margin divided by selling price, expressed as a percentage. A 60% ratio means 60 cents of every dollar in revenue goes toward fixed costs and profit.

Target Profit

A desired profit goal used to calculate how many units you need to sell beyond the break-even point. Calculated as: (Fixed Costs + Target Profit) ÷ Contribution Margin.
