What Is Break-Even Analysis?

Break-even analysis is a fundamental financial calculation that tells you exactly how many units of a product or service you need to sell to cover all your costs. At the break-even point, your total revenue equals your total costs — you're not making a profit, but you're not losing money either.

This calculator helps business owners, entrepreneurs, and financial planners quickly determine their break-even point by analyzing three key inputs: fixed costs, variable cost per unit, and selling price per unit.

Why it matters: Understanding your break-even point is essential for making informed pricing decisions, setting realistic sales targets, and evaluating business viability before investing significant resources.

Why Break-Even Analysis Matters

Pricing Decisions

Understand the minimum price you need to charge to cover costs and ensure profitability

Sales Targets

Know exactly how many units you need to sell to start generating profit

Risk Assessment

Evaluate whether a business idea or product launch is financially viable before committing

Cost Management

See how reducing fixed or variable costs impacts your break-even point and profitability

Key Concepts

Fixed Costs

Expenses that remain constant regardless of production volume

Rent and utilities
Salaries and insurance
Equipment and subscriptions

Variable Costs

Expenses that change with each unit produced

Raw materials
Packaging and shipping
Direct labor per unit

Contribution Margin

The difference between selling price and variable cost per unit

Revenue per unit after variable costs
Contributes to covering fixed costs
Higher margin = faster break-even

How to Use the Break Even Calculator

Follow these simple steps to calculate your break-even point and explore different business scenarios.

Enter Your Costs and Price

Fill in the three required fields with your business data:

Fixed Costs — Your total monthly or annual fixed expenses (rent, salaries, insurance, utilities)
Variable Cost per Unit — How much it costs to produce or acquire one unit (materials, packaging, shipping per item)
Selling Price per Unit — The price you charge customers for one unit

Real-time updates: Results update instantly as you type — no need to press a calculate button.

Review Your Results

The calculator displays four key metrics to help you understand your business performance:

Break-Even Point — The number of units you need to sell to cover all costs
Break-Even Revenue — The total revenue needed to reach the break-even point
Contribution Margin — Profit per unit after subtracting variable costs
Margin Ratio — Contribution margin as a percentage of selling price

Set a Target Profit (Optional)

Enter a desired profit amount to see how many additional units you need to sell beyond the break-even point to reach your profit goal. This helps you set realistic sales targets and revenue objectives.

Explore What-If Scenarios

Open the What-If Scenarios panel and use the sliders to adjust your selling price or variable cost by up to 50% in either direction. This helps you understand how pricing and cost changes affect your break-even point before making real business decisions.

Frequently Asked Questions

What is a break-even point?

The break-even point is the number of units you need to sell so that your total revenue exactly covers your total costs (both fixed and variable). At this point, your profit is zero — selling more units beyond this point generates profit.

Key insight: Understanding your break-even point helps you set minimum sales targets and evaluate business viability.

What is the break-even formula?

The break-even formula is:

Break-Even Units = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit)

The denominator is called the Contribution Margin — it represents how much each unit sale contributes toward covering fixed costs. A higher contribution margin means you need to sell fewer units to break even.

What are fixed costs vs. variable costs?

Fixed Costs

Stay the Same

Expenses that remain constant regardless of production volume:

Rent and utilities
Salaries and insurance
Loan payments
Software subscriptions

Variable Costs

Change Per Unit

Expenses that change with each unit produced:

Raw materials
Packaging and shipping
Sales commissions
Direct labor per item

What does the contribution margin mean?

The contribution margin is the selling price minus the variable cost per unit. It shows how much each sale contributes to covering your fixed costs.

Important: A higher contribution margin means fewer units needed to break even. This is why pricing strategy and cost control are crucial for profitability.

Example: If you sell a product for $50 and it costs $30 in variable costs to produce, your contribution margin is $20. This $20 from each sale goes toward covering your fixed costs like rent and salaries.

What does it mean when the result shows "—"?

Warning: A dash (—) appears when your selling price is less than or equal to your variable cost per unit. In this case, every unit sold loses money, making it impossible to ever break even.

To fix this situation, you need to:

Increase your selling price to exceed variable costs
Reduce your variable cost per unit through better sourcing or efficiency
Reconsider the business model if neither option is viable

How do I use the What-If Scenarios?

Open the What-If Scenarios panel and drag the sliders to adjust your selling price or variable cost by a percentage. This lets you test different pricing strategies and see how they affect your break-even point without changing your original inputs.

Use cases:

Test the impact of a 10% price increase on break-even units
See how negotiating better supplier rates affects profitability
Evaluate discount strategies before implementing them
Compare multiple scenarios side-by-side
