Break-Even Calculator
Calculate your break-even point, the number of units you need to sell to cover all costs. Enter your fixed costs, variable costs per unit, and selling price to determine your break-even units, break-even revenue, contribution margin, and margin of safety.
What Is Break-Even Analysis?
Break-even analysis is a financial calculation that determines the point at which total revenue equals total costs — the point where a business neither makes a profit nor incurs a loss. The break-even point (BEP) is the number of units a business must sell to cover all its fixed and variable costs.
The break-even formula is:
Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit)
Where:
Fixed Costs: Costs that don't change with sales volume (rent, salaries, insurance)
Price per Unit: Selling price of one unit
Variable Cost per Unit: Costs that change with each unit sold (materials, labor, shipping)
Contribution Margin = Price per Unit − Variable Cost per Unit
Break-Even Revenue = Break-Even Units × Price per Unit
The calculator also shows your margin of safety — how much sales can drop before you start losing money — and your expected profit based on your sales forecast.
How Does the Break-Even Calculator Work?
The calculator performs the following calculations:
- Contribution Margin: Price per Unit − Variable Cost per Unit — the amount each unit contributes to covering fixed costs.
- Break-Even Units: Fixed Costs ÷ Contribution Margin — the number of units you need to sell to break even.
- Break-Even Revenue: Break-Even Units × Price per Unit — the revenue needed to break even.
- Expected Profit: (Expected Sales × Contribution Margin) − Fixed Costs — your profit at expected sales.
- Margin of Safety: Expected Sales − Break-Even Units — how much sales can drop before you incur losses.
You can also include a tax rate to see your after-tax profit.
Why Use This Break-Even Calculator?

Key Break-Even Concepts
- Fixed Costs: Costs that remain constant regardless of sales volume (rent, salaries, insurance).
- Variable Costs: Costs that change with sales volume (materials, shipping, commissions).
- Contribution Margin: The amount each unit contributes to covering fixed costs and generating profit.
- Margin of Safety: The difference between actual sales and break-even sales — a measure of risk.
❓ Break-Even Calculator FAQ
What is the break-even point?
The break-even point is the number of units a business must sell to cover all its costs — fixed and variable. At the break-even point, total revenue equals total costs, meaning the business makes neither a profit nor a loss.
What is the formula for break-even point?
Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). The denominator is the contribution margin per unit.
What are fixed costs?
Fixed costs are expenses that do not change with sales volume. Examples include rent, salaries, insurance, and loan payments. They remain constant regardless of how many units you sell.
What are variable costs?
Variable costs change with sales volume. Examples include raw materials, shipping costs, and sales commissions. The more units you sell, the higher your variable costs.
What is contribution margin?
Contribution margin is the difference between the selling price per unit and the variable cost per unit. It represents the amount each unit contributes to covering fixed costs and generating profit.
How do I calculate break-even revenue?
Break-even revenue = Break-Even Units × Price per Unit. This is the total sales revenue needed to cover all costs.
What is margin of safety?
Margin of safety is the difference between your actual or expected sales and your break-even sales. It shows how much sales can drop before you start losing money.
What is a good margin of safety?
A higher margin of safety indicates lower risk. A margin of safety of 20-30% is generally considered healthy, meaning sales can drop by that amount before you incur losses.
How does changing the price affect break-even?
Increasing the price per unit increases the contribution margin, which lowers the break-even point. Decreasing the price has the opposite effect — it raises the break-even point.
How do variable costs affect break-even?
Higher variable costs reduce the contribution margin, which increases the break-even point. Lower variable costs improve the contribution margin and lower the break-even point.
How do fixed costs affect break-even?
Higher fixed costs increase the break-even point because more units must be sold to cover those costs. Lower fixed costs reduce the break-even point.
What is the difference between break-even and profit?
Break-even is the point where total revenue equals total costs — no profit, no loss. Profit is what remains after all costs are covered, and it starts accumulating once you sell beyond the break-even point.
How do I use break-even analysis for business planning?
Break-even analysis helps you understand the minimum sales volume needed to avoid losses. It guides pricing decisions, cost management, and sales target setting. It's essential for business plans and financial projections.
What is the break-even point for a service-based business?
For service businesses, the break-even point can be calculated in terms of hours billed or clients served. The formula is similar: Break-Even = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit).
Can break-even analysis be used for multiple products?
Yes, but it becomes more complex. For multiple products, you need to calculate a weighted average contribution margin based on the sales mix. This calculator is designed for a single product or service.
What is the break-even point in sales dollars?
Break-even sales dollars = Fixed Costs ÷ Contribution Margin Ratio. The contribution margin ratio is Contribution Margin ÷ Price per Unit.
How does the calculator handle taxes?
The calculator includes an optional tax rate field. When you enter a tax rate, it calculates after-tax profit at expected sales, giving you a more realistic picture of your net earnings.
What is the difference between break-even and payback period?
Break-even analysis measures when a product or business becomes profitable (revenue = costs). Payback period measures how long it takes to recover an initial investment. They are different concepts used for different purposes.
How accurate is this break-even calculator?
This calculator provides accurate results based on the standard break-even formula. However, actual business performance may vary due to factors like seasonality, competition, and economic conditions. Use this as a planning tool, not a guarantee.
