Use this Break Even Calculator to estimate how many units you need to sell, or how much revenue you need to generate, before your business starts making a profit. It helps you understand the point where your total revenue covers your fixed and variable costs.
Break-even analysis is useful for startups, small businesses, ecommerce sellers, service providers, and anyone planning a new product, pricing strategy, or business investment. Instead of guessing whether your idea can become profitable, this calculator gives you a clear estimate based on your costs and selling price.

What is a break-even point?
The break-even point is the sales level where your business covers all costs but has not yet made a profit. At this point, your profit is zero because total revenue is equal to total cost.
For example, if your business spends money on rent, salaries, software, packaging, production, or other operating costs, you need enough sales to recover those expenses. Once your sales move above the break-even point, the extra contribution can start turning into profit.
Break-even formula
The basic break-even formula is:
Break-even units = Fixed costs ÷ (Selling price per unit − Variable cost per unit)
The part inside the brackets is called the contribution margin per unit. It shows how much each sale contributes toward covering fixed costs after variable costs are removed.
For revenue-based planning, the formula is:
Break-even revenue = Break-even units × Selling price per unit
How to use the Break Even Calculator
To calculate your break-even point, enter your fixed costs, selling price per unit, and variable cost per unit. Fixed costs are expenses that usually stay the same, such as rent, salaries, insurance, software subscriptions, or equipment costs. Variable costs change with each sale, such as product cost, packaging, payment processing fees, shipping, or production materials.
After entering the values, the calculator estimates how many units you need to sell and how much revenue you need to generate to reach break-even. You can adjust the numbers to compare different pricing, cost, and sales scenarios.
Why break-even analysis matters
Break-even analysis helps you understand whether your business model is realistic. If your break-even sales target is too high, it may mean your fixed costs are too heavy, your selling price is too low, or your variable costs are reducing your margin.
It is especially helpful before launching a new product, opening a store, starting an online business, offering a service package, or investing in marketing. A clear break-even estimate can help you avoid underpricing, control costs, and set better sales targets.
Example of break-even calculation
Suppose your fixed costs are $5,000, your selling price is $50 per unit, and your variable cost is $30 per unit. Your contribution margin per unit is $20.
$5,000 ÷ $20 = 250 units
This means you need to sell 250 units to break even. At a selling price of $50, your break-even revenue would be $12,500.
How to improve your break-even point
If your break-even point is too high, there are a few ways to improve it. You can increase your selling price, reduce variable costs, lower fixed expenses, improve your product margin, or increase the average value of each sale.
For pricing and profitability planning, you can also use the Profit Margin Calculator and Markup Calculator. These tools help you understand whether your pricing gives you enough room to cover costs and earn profit.

Break Even Calculator FAQs
What does a break-even calculator do?
A break-even calculator estimates the number of units or amount of revenue needed to cover your total business costs. It helps you understand when your business, product, or service starts becoming profitable.
What is included in fixed costs?
Fixed costs usually include expenses that do not change directly with each sale. Common examples include rent, salaries, insurance, software, loan payments, equipment costs, and other regular operating expenses.
What is included in variable cost per unit?
Variable cost per unit includes expenses that increase when you sell one more unit. This can include product cost, packaging, shipping, transaction fees, production materials, and other direct costs linked to each sale.
Is break-even the same as profit?
No. Break-even means your revenue covers your costs, but you have not made a profit yet. Profit starts after your sales move above the break-even point.
How can I lower my break-even point?
You can lower your break-even point by reducing fixed costs, lowering variable costs, increasing your selling price, or improving your contribution margin. A lower break-even point usually means your business needs fewer sales to cover costs.
Can this calculator be used for a service business?
Yes. Service businesses can use break-even analysis by treating each service sale, project, client package, or billable hour as a unit. Fixed costs may include salaries, rent, software, and admin expenses, while variable costs may include contractor fees, materials, or payment processing charges.
