About Break-Even Calculator
The break-even point is where total revenue equals total costs (fixed + variable). Formula: BEP (units) = Fixed Costs / (Selling Price - Variable Cost). The contribution margin is the amount each unit contributes toward covering fixed costs.
How to Use This Calculator
Enter your total fixed costs — say $50,000 for rent, salaries, and equipment. Input the variable cost per unit — for example, $20 for materials and labor. Enter your selling price per unit — say $50. Click Calculate to see how many units you need to sell to break even, the break-even revenue, and your contribution margin per unit. The chart shows the intersection point where total revenue equals total costs.
How to Interpret Your Results
With $50,000 fixed costs, $20 variable cost per unit, and $50 selling price: Contribution Margin = $30 per unit, Break-Even Units = 1,667 units, Break-Even Revenue = $83,350. You need to sell 1,667 units just to cover all costs. Every unit sold beyond that contributes $30 toward profit. If you raise the price to $55, break-even drops to 1,429 units — 238 fewer units needed. The chart shows the total revenue line crossing the total cost line at the break-even point.
When to Use This Calculator
Use this before launching any product to determine if your business model is viable. It's essential when deciding pricing strategies — you can see how a price increase affects the break-even point. Restaurants and manufacturers use it to decide menu prices or production volumes. It's also useful for evaluating whether to add a new product line or enter a new market. Investors use break-even analysis to assess the risk of a business investment.
Frequently Asked Questions
What is the difference between fixed costs and variable costs?
Fixed costs don't change with production volume — rent, salaries, insurance, equipment leases, and loan payments. These must be paid regardless of whether you sell 0 units or 10,000 units. Variable costs change directly with production — raw materials, direct labor, packaging, shipping, and sales commissions. Some costs like utilities are mixed — a fixed base plus variable usage component. Separating these correctly is crucial for accurate break-even analysis.
How do I calculate my break-even point in units vs dollars?
Break-even in units is calculated as Fixed Costs divided by (Selling Price minus Variable Cost per Unit). For example, with $50,000 fixed costs, $20 variable cost, and $50 selling price: $50,000 / ($50 - $20) = 1,667 units. Break-even in dollars is simply the break-even units multiplied by the selling price: 1,667 x $50 = $83,350. The dollar break-even tells you the total revenue needed to cover all costs, which is useful for businesses with multiple products where a blended contribution margin must be used.
What happens to break-even if I lower my prices?
Lowering your price reduces your contribution margin (price minus variable cost), which increases the number of units needed to break even. If you drop the price from $50 to $40 while keeping $20 variable cost and $50,000 fixed costs, your break-even units jump from 1,667 to 2,500 — a 50% increase. You would need to sell 833 more units just to stay profitable. Always model price changes through break-even analysis before discounting, as the increased volume needed may not be achievable.
How does contribution margin affect break-even analysis?
Contribution margin is the selling price minus variable cost per unit — the amount each sale contributes toward covering fixed costs. A higher contribution margin means you reach break-even faster. For example, a $50 product with $20 variable cost has a $30 contribution margin, requiring 1,667 units to break even. If you reduce variable costs to $15, the contribution margin rises to $35, dropping break-even to 1,429 units. Contribution margin ratio (contribution margin divided by price) helps compare profitability across different products or pricing tiers.
What is a good break-even period for a new business?
Most investors and lenders expect a new business to reach break-even within 6-18 months of operations. Service-based businesses with low fixed costs often break even in 3-6 months, while manufacturing or retail businesses requiring significant upfront inventory investment may take 12-24 months. A break-even period beyond 24 months is considered high-risk for most traditional businesses. Your break-even analysis should be conservative — underestimating costs or overestimating sales volume are the most common mistakes new business owners make.
