Break Even Point Calculator
Determine exactly how many units you need to sell before your business starts making a profit. Essential for pricing decisions, startup planning, and evaluating new product launches.
About this calculator
The break-even point is the number of units a business must sell so that total revenue exactly equals total costs — neither profit nor loss. The formula is: Break-Even Point (units) = Fixed Costs / (Price per Unit − Variable Cost per Unit). The denominator, Price per Unit minus Variable Cost per Unit, is known as the contribution margin per unit — the amount each sale contributes toward covering fixed costs. Fixed costs are expenses that do not change with production volume, such as rent and salaries. Variable costs change proportionally with output, such as raw materials or packaging. If the price per unit equals the variable cost per unit, the contribution margin is zero and no volume of sales can cover fixed costs, making break-even undefined. Understanding your break-even point helps set realistic sales targets and assess business viability.
How to use
Imagine a small business with $10,000 in monthly fixed costs (rent, salaries, utilities), a selling price of $50 per unit, and a variable cost of $30 per unit. First, calculate the contribution margin: $50 − $30 = $20 per unit. Then apply the formula: Break-Even Point = $10,000 / $20 = 500 units. This means the business must sell 500 units each month just to cover all its costs. Enter $10,000 in Fixed Costs, $50 in Price per Unit, and $30 in Variable Cost per Unit to see this result instantly.
Frequently asked questions
How do I use the break-even point to set a sales target?
Your break-even point gives you a floor — the minimum sales volume needed to avoid a loss. To set a meaningful sales target, add your desired profit on top: Sales Target = (Fixed Costs + Desired Profit) / Contribution Margin per Unit. For example, if your break-even is 500 units and you want $5,000 profit with a $20 contribution margin, your target is (10,000 + 5,000) / 20 = 750 units. This transforms the break-even calculation into a practical planning tool for budgeting and goal-setting.
What happens to the break-even point if I lower my selling price?
Lowering your selling price reduces the contribution margin per unit, which means you need to sell more units to cover the same fixed costs. For example, dropping your price from $50 to $45 while keeping variable costs at $30 changes the contribution margin from $20 to $15, pushing the break-even from 500 units to 667 units. This is why pricing decisions must account for break-even analysis. A lower price might attract more customers, but the increased volume needed to break even must be realistic given market demand.
Why is break-even analysis important for startups and new product launches?
Break-even analysis is critical early in a business or product lifecycle because it answers the fundamental question: can this venture realistically pay for itself? It forces entrepreneurs to quantify fixed costs, price competitively, and estimate achievable sales volumes before committing resources. If the required break-even volume exceeds realistic market demand, the business model needs adjustment — whether by cutting fixed costs, raising prices, or reducing variable costs. Investors and lenders also use break-even figures to assess financial risk before funding a venture.
