Break-Even Calculator
Find how many units you need to sell to cover all your costs. Enter your fixed costs, selling price, and variable cost per unit to calculate your break-even point instantly.
What Is a Break-Even Point?
The break-even point is where a business's total revenue equals its total costs — the threshold between loss and profit. Below the break-even point, you are losing money. Above it, you are generating profit. Every business owner, entrepreneur, and product manager should know their break-even point before launching.
Break-even analysis is especially valuable when pricing a new product, evaluating a new business venture, deciding whether to add a product line, or determining how many sales you need to justify a marketing spend.
Break-Even Formula
The break-even calculation uses three inputs:
- Fixed Costs (FC): Costs that do not change with production volume (rent, salaries, insurance)
- Selling Price per Unit (P): The price at which each unit is sold
- Variable Cost per Unit (VC): Costs that scale with each unit produced (materials, packaging, commissions)
Contribution Margin = Price − Variable Cost
Break-Even Units = Fixed Costs ÷ Contribution Margin
Break-Even Revenue = Break-Even Units × Selling Price
Example: A small bakery has $8,000 in monthly fixed costs (rent, equipment, insurance). Each custom cake sells for $80 and costs $30 in ingredients. The contribution margin is $50 per cake. The break-even point is $8,000 ÷ $50 = 160 cakes per month. At that volume, monthly revenue is $12,800 — exactly covering all costs.
Break-Even Analysis for Small Businesses
Break-even analysis is one of the most practical tools in small business planning. Here are common scenarios where it provides critical insight:
| Scenario | How Break-Even Helps |
|---|---|
| Launching a new product | Know exactly how many units must sell to cover launch costs |
| Setting a price | Understand how pricing changes affect required sales volume |
| Evaluating a rent increase | Calculate how many additional units you need to absorb higher fixed costs |
| Hiring an employee | Determine the additional revenue needed to cover the salary |
| Planning a marketing campaign | Estimate the minimum sales the campaign must generate to pay for itself |
Breaking even is not the goal — profitability is. But knowing your break-even point tells you exactly how far you are from profitability and what levers you can pull to get there faster.
Break-Even Calculator FAQs
What is the break-even point?
The break-even point is the number of units you must sell (or amount of revenue you must generate) for total revenue to exactly equal total costs — meaning you have neither a profit nor a loss. Any sales beyond this point generate profit.
What are fixed costs vs. variable costs?
Fixed costs remain constant regardless of production volume — examples include rent, salaries, insurance, and equipment depreciation. Variable costs change with each unit produced or sold — examples include raw materials, packaging, and sales commissions.
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 fixed costs and generating profit. A higher contribution margin means you reach break-even faster.
How can a business lower its break-even point?
You can lower the break-even point by reducing fixed costs (e.g., renegotiating rent, reducing headcount), reducing variable costs per unit (e.g., better supplier pricing, more efficient production), or increasing the selling price. Often a combination of all three is most effective.
