Break-even analysis is a financial calculation that determines the point at which total revenue equals total costs—meaning your business is neither making a profit nor incurring a loss. It's one of the most important tools for business planning and financial decision-making.
The Break-even Point tells you:
1. Startup Planning: Break-even analysis helps you figure out if your business idea can actually make money. Before you launch, you can set sales goals that make sense and understand how much money you'll need to get started.
2. Pricing Decisions: When you know your break-even point, you can set prices that will make your business profitable. You can also see what happens when you change your prices and compare different pricing options to find the best one.
3.Cost Management: This analysis shows you how changes in your costs affect your profits. You can decide whether to use more fixed costs (like salaries) or variable costs (like materials), and figure out which cost-cutting ideas will actually help your bottom line.
4. Investment Decisions: Before you spend money on big purchases, break-even analysis helps you understand the risks. You can evaluate whether buying new equipment or technology makes sense, and plan for expansion with confidence.
1. Fixed Costs: Fixed costs stay the same no matter how many units you sell. Even if you don't sell anything, you still have to pay these costs. Common examples include:
2. Variable Costs: Variable costs change based on how many units you produce or sell. When you're not producing anything, these costs drop to zero. The more you sell, the more these costs add up. Common examples include:
3. Contribution Margin: The contribution margin tells you how much money from each sale is left over to cover your fixed costs and generate profit. The formula is simple:
Contribution Margin = Price per Unit - Variable Cost per Unit
If you sell a product for $50 and your variable costs are $30 per unit, your contribution margin is $20. This means each sale puts $20 toward covering your rent, salaries, and other fixed costs. Once you've covered all those fixed costs, that $20 becomes pure profit.
4. Contribution Margin Ratio: This ratio shows you what percentage of each sales dollar actually helps cover your fixed costs and create profit. The formula:
Contribution Margin Ratio = Contribution Margin ÷ Price per Unit
Using the same example, With a $20 contribution margin and a $50 selling price, your ratio is 40%. This means that for every dollar you bring in, 40 cents goes toward covering fixed costs and profit, while the other 60 cents covers variable costs.
The calculator starts with three essential fields:
This is how much you charge for one unit of your product or service.
Tips for accurate pricing:
Enter how many units you're currently selling (or expect to sell) in your chosen time period.
Tips for realistic estimates:
If you have a specific profit goal in mind, enter it here. The calculator will show you exactly how many units you need to sell to reach that goal.
In the Fixed Costs Breakdown section, list all your costs that stay the same regardless of sales volume. The calculator provides example categories to get you started:
Common fixed cost categories:
Add as many cost items as you need. This detailed breakdown helps you identify where your money is going and which costs you might be able to reduce.
In the Variable Costs Breakdown section, list all costs that change based on how many units you produce or sell. Enter the cost per unit for each category:
Common variable cost categories:
The calculator will automatically total these up to determine your total variable cost per unit.
Once you've entered all your information, the calculator shows you several important metrics:

This section breaks down your costs:
The calculator creates three charts to help you visualize your break-even analysis:
This line chart shows you the big picture. You'll see:
Where the revenue line crosses the total costs line is your break-even point. Everything to the right of that intersection is profit territory.
This doughnut chart shows you exactly where your money is going. You can see:
This is super helpful for identifying which costs you might want to focus on reducing.
This bar chart shows you what happens to your profit at different sales levels. You can see:
Understanding the math behind break-even analysis helps you make better decisions. Here are the key formulas the calculator uses:
This is the fundamental formula that tells you how many units you need to sell:
Break-even Units = Fixed Costs ÷ Contribution Margin per Unit
Here's a real example: Let's say you have $10,000 in monthly fixed costs, you sell your product for $50, and each unit costs $30 in variable costs. Your contribution margin is $20 per unit ($50 - $30).
Break-even units = $10,000 ÷ $20 = 500 units
You need to sell 500 units to break even.
Once you know how many units you need to sell, you can calculate the revenue needed:
Break-even Revenue = Break-even Units × Price per Unit
Using the same example: Break-even revenue = 500 units × $50 = $25,000
You need to generate $25,000 in revenue to break even.
Want to know how many units you need to sell to hit a specific profit goal? Use this formula:
Units for Target Profit = (Fixed Costs + Target Profit) ÷ Contribution Margin
Continuing our example: If you want to make $5,000 in profit:
Units needed = ($10,000 + $5,000) ÷ $20 = 750 units
You need to sell 750 units to make your target profit of $5,000.
This tells you how much cushion you have above your break-even point:
Margin of Safety = Current Sales - Break-even Sales
Margin of Safety % = (Margin of Safety ÷ Current Sales) × 100
Final example: If you're currently selling 800 units and your break-even is 500 units:
Margin of safety = 800 - 500 = 300 units (37.5%)
This means your sales could drop by 37.5% before you start losing money. The higher this percentage, the safer your business position.
Let's look at how different businesses can use break-even analysis to make smarter decisions.
Your situation: You're launching a new product priced at $75. Your variable costs are $45 per unit, and you'll have $15,000 in monthly fixed costs (rent, salaries, utilities, etc.).
How to use the calculator:
This helps you decide if the product launch makes financial sense before you invest.
Your situation: You're debating whether to price your product at $50 or $60, and your variable costs are $30 per unit.
Compare both scenarios:
Option 1 - Price at $50:
Option 2 - Price at $60:
The higher price gives you a lower break-even point, which means less risk. But you also need to think about whether customers will pay the higher price.
Your situation: You can buy equipment for $2,000 that will reduce your variable costs by $5 per unit.
Compare before and after:
Current situation:
After buying the equipment:
The investment reduces your break-even by 20 units. If you're selling more than 400 units, this investment makes sense.
Your situation: You're thinking about opening a second location, which would double your fixed costs but give you more sales potential.
Current business:
With second location:
This shows you need 63% more sales to maintain the same profit level. The analysis helps you understand the risk before making the expansion.
Your situation: You run a consulting business charging $150/hour. Your variable costs (materials, travel) are $50/hour, and your monthly overhead is $8,000.
What the analysis shows:
This helps you understand how much work you need to land each month to stay profitable.
While break-even analysis is incredibly useful, it has some limitations you should know about:
In reality, things are more complex:
Use break-even analysis as a guide, but be ready to adjust for these realities.
Break-even analysis shows you a single point in time:
You'll want to use cash flow analysis alongside break-even analysis for a complete picture.
The clean division between fixed and variable costs isn't always perfect:
These simplifications are useful for decision-making, but remember they're approximations.
If you have multiple products:
For multi-product businesses, the analysis becomes more complex but is still valuable.
Once you've completed your break-even analysis, here's what to do next:
Test Different Scenarios: Use the calculator to see what happens if prices change, costs go up, or sales volumes shift. This helps you prepare for different possibilities.
Plan Your Cash Flow: Break-even tells you about profitability, but you also need to know when money actually comes in and goes out. Create a cash flow projection to make sure you can cover your bills.
Calculate Funding Needs: If you're starting a new business, figure out how long it will take to reach break-even. You'll need enough funding to cover losses during that period.
Develop Your Marketing Plan: Now that you know how many units you need to sell, create a realistic plan for how you'll reach those customers.
Assess Your Risks: What happens if your assumptions are wrong? What if it takes longer to reach sales targets? Having backup plans reduces stress.
