What Is Break-Even Point?
The break-even point is the number of units you must sell to cover all your business costs—both fixed and variable. At this point, your total revenue equals your total costs, meaning you're not making a profit but you're also not losing money.
Understanding your break-even point helps you:
- Set realistic sales targets
- Price products appropriately
- Evaluate business viability
- Make informed decisions about costs and investments
- Plan for profitability
How to Use This Calculator
- Enter Fixed Costs: Total costs that don't change with production volume (rent, salaries, insurance, software subscriptions)
- Enter Variable Cost Per Unit: Costs that change with each unit produced (raw materials, direct labor, packaging, shipping)
- Enter Selling Price Per Unit: The price you charge customers for each unit
- Click Calculate: See your break-even point in units and revenue
Example: A small bakery has monthly fixed costs of $10,000 (rent, utilities, salaries). Each cake costs $15 to make (ingredients, packaging) and sells for $40.
Break-Even Calculation: Contribution margin = $40 - $15 = $25 per cake. Break-even point = $10,000 ÷ $25 = 400 cakes.
Result: The bakery must sell 400 cakes per month to cover all costs.
Understanding the Results
Break-Even Units: The exact number of units you need to sell to cover costs. Selling more means profit; selling less means a loss.
Break-Even Revenue: The total sales revenue at break-even point (units × selling price).
Contribution Margin: The amount each unit contributes to covering fixed costs after variable costs are paid (selling price - variable cost).
Contribution Margin %: The percentage of each sale that contributes to fixed costs and profit.
Important Assumptions
- Fixed costs remain constant regardless of production volume
- Variable costs per unit stay the same at all production levels
- Selling price remains unchanged
- All units produced are sold
- Product mix stays constant if selling multiple products

Frequently Asked Questions
What if my contribution margin is negative?
If your variable cost per unit exceeds your selling price, you have a negative contribution margin. This means you lose money on every sale. You must either increase your selling price or reduce variable costs—otherwise, the business model isn't viable.
How often should I calculate my break-even point?
Recalculate whenever there's a significant change in fixed costs, variable costs, or pricing. Many businesses review break-even analysis monthly or quarterly, and always before making major decisions like expanding operations or launching new products.
Can I use this for a service business?
Yes. For service businesses, "units" might represent billable hours, number of clients, or service packages. Fixed costs include office rent and salaries, while variable costs include materials or contractor fees per service delivered.
What's a good contribution margin percentage?
This varies by industry. Software companies often have 80%+ margins, while retail might be 20-50%, and food service 60-70%. Higher margins give you more cushion to cover fixed costs and generate profit, but what matters most is whether your margin allows you to cover fixed costs at realistic sales volumes.
Does break-even analysis work for multiple products?
This calculator is designed for a single product or weighted average. For multiple products, calculate a weighted average selling price and variable cost based on your expected sales mix, or calculate break-even for each product separately.
What happens after I reach break-even?
Every unit sold beyond break-even contributes the full contribution margin to profit. For example, if your contribution margin is $25 per unit and you sell 50 units beyond break-even, you generate $1,250 in profit.
