The break-even point tells you exactly when your startup stops losing money and starts covering its costs. It’s a critical financial milestone that helps you:
- Set sales or revenue targets to cover costs.
- Understand fixed vs. variable expenses and their impact on profitability.
- Calculate the minimum sales volume needed to avoid losses.
- Plan pricing strategies and allocate resources efficiently.
Here’s the quick formula:
- Break-Even Point (Units) = Fixed Costs ÷ Contribution Margin Per Unit
- Break-Even Point (Sales $) = Fixed Costs ÷ Contribution Margin Ratio
For example, if your fixed costs are $10,000, your product sells for $40, and variable costs are $15, you need to sell 400 units or earn $16,000 in revenue to break even.
Whether you sell one product or multiple, understanding this number helps you make smarter financial decisions, attract investors, and avoid running out of cash. Simple tools like spreadsheets or AI-powered platforms can simplify these calculations, making it easier to adjust as your business grows.
Break-Even Analysis Basics
What Is the Break-Even Point?
The break-even point marks the sales level where your startup's total revenue matches its total costs, leaving you with neither profit nor loss. It's the moment when your business stops losing money and starts inching toward profitability.
This metric is more than just a number - it’s a key benchmark for evaluating your financial health. Once you cross this threshold, every additional sale contributes directly to your profits.
For startups navigating competitive markets and tight budgets, the break-even point is like a financial compass. It helps you assess whether your business model is sustainable and sets realistic sales goals before scaling. Without understanding this, planning for growth or pitching to investors becomes a guessing game.
To better grasp the break-even point, it's important to first distinguish between fixed costs and variable costs.
Fixed Costs vs. Variable Costs
To calculate your break-even point accurately, you need to separate fixed costs from variable costs. These two categories behave differently as your business grows, and mixing them up can lead to unreliable financial projections.
Fixed costs are expenses that stay the same no matter how much you sell. Whether you sell one product or 1,000, these costs remain constant month after month. Common fixed costs for U.S. startups include:
- Office rent: $2,000 per month
- Salaried employees: $5,000 monthly
- Insurance premiums: $300 per month
Other examples include software subscriptions, equipment leases, and legal fees.
Variable costs, on the other hand, increase as your sales or production volume grows. The more you sell, the higher these costs climb. Typical variable costs for startups might include:
- Manufacturing costs: $10 per unit
- Payment processing fees: 2.9% per transaction
- Shipping costs: $3 per order
For a SaaS business, server usage fees that grow with more users would be a variable cost, while developer salaries would remain fixed.
Understanding the difference is crucial. Fixed costs must be paid regardless of sales, while variable costs only kick in when you make a sale.
Contribution Margin Explained
Now that we’ve defined costs, let’s talk about the contribution margin - a measure of how much profit each unit sold contributes toward covering your fixed costs. It’s calculated with this formula:
Contribution Margin per Unit = Selling Price per Unit - Variable Cost per Unit
This figure is key to break-even analysis because it tells you exactly how many units you need to sell to cover your fixed costs and start making a profit.
Here’s an example: Suppose you sell a product for $50 per unit, and your variable costs are $5 per unit. Your contribution margin is $45 ($50 - $5). If your monthly fixed costs are $15,000, you’d need to sell 334 units to break even ($15,000 ÷ $45 = 333.33, rounded up).
The contribution margin also highlights the impact of each sale. In this case, every unit sold contributes $45 toward covering fixed costs. Once you’ve sold enough to cover those costs, that $45 becomes pure profit on every additional sale.
Break Even Analysis - Simple for Startups and Entrepreneurs
How to Calculate Break-Even Point
When it comes to break-even analysis, there are two main approaches: calculating based on units sold and calculating based on sales dollars. Each method serves a different purpose, helping you make informed decisions for your financial planning.
Break-Even Point in Units
The break-even point in units tells you how many products you need to sell to cover all your costs. This approach is especially useful for startups because it sets a clear sales target.
Here’s the formula:
Break-Even Point (Units) = Fixed Costs ÷ Contribution Margin Per Unit
Let’s break it down with an example. Imagine a subscription box company with these monthly figures:
- Fixed costs: $10,000 (office rent, salaries, insurance)
- Selling price per box: $40
- Variable cost per box: $15 (products, packaging, shipping)
First, calculate the contribution margin per unit. Subtract the variable cost from the selling price: $40 - $15 = $25 per box.
Now, plug the numbers into the formula: $10,000 ÷ $25 = 400 boxes per month.
This means you need to sell 400 boxes each month to break even. It’s a straightforward calculation that gives you a clear sales goal. For example, if you’re currently selling 200 boxes a month, you know you need to double your sales to hit the break-even point. But sometimes, focusing on revenue might provide a better perspective, which is where the next method comes in.
Break-Even Point in Sales Dollars
If unit-based targets don’t align with your business model - especially if you sell multiple products or services - calculating the break-even point in sales dollars can be more insightful. This method focuses on the total revenue you need to generate to cover your costs.
Here’s the formula:
Break-Even Point (Sales $) = Fixed Costs ÷ Contribution Margin Ratio
To find the contribution margin ratio, divide the contribution margin per unit by the selling price. Using the subscription box example:
Contribution margin ratio = $25 ÷ $40 = 0.625 or 62.5%
This means 62.5% of every dollar earned goes toward covering fixed costs and profit, while the remaining 37.5% covers variable costs.
Now calculate the break-even revenue: $10,000 ÷ 0.625 = $16,000 per month.
Notice how the numbers align: 400 boxes × $40 = $16,000 in revenue.
This revenue-based approach is particularly helpful for setting marketing budgets or revenue goals. Instead of focusing on unit sales, you can aim for a monthly revenue target of $16,000.
Both methods ultimately lead to the same result. The choice between them depends on what makes the most sense for your business and how you prefer to set your goals. Whether you’re targeting units sold or total revenue, these calculations provide a clear roadmap for achieving financial stability.

Break-Even Analysis for Multiple Products
Startups often juggle multiple products, each with its own pricing, costs, and profit margins. Because of this, a single break-even calculation won’t cut it. Instead, you need to calculate a weighted average contribution margin to determine a realistic break-even point that reflects your product mix. This method provides a clearer picture of how your business operates.
Weighted Average Contribution Margin
The weighted average contribution margin represents the average profitability of all your products, adjusted for their share of total sales. It’s calculated by finding each product’s contribution margin (selling price minus variable cost), multiplying it by the product’s sales mix percentage, and summing up these values.
Here’s a quick example. Imagine a SaaS startup with three subscription plans:
| Product | Selling Price | Variable Cost | Contribution Margin | Sales Mix | Weighted Contribution |
|---|---|---|---|---|---|
| Basic Plan | $50 | $15 | $35 | 60% | $21.00 |
| Pro Plan | $100 | $25 | $75 | 30% | $22.50 |
| Enterprise | $200 | $40 | $160 | 10% | $16.00 |
| Total | 100% | $59.50 |
In this case, the Basic Plan has the lowest contribution margin at $35, but since it accounts for 60% of sales, its weighted contribution is $35 × 60% = $21.00. On the other hand, the Enterprise plan has the highest margin at $160, but its smaller 10% sales mix means it contributes $160 × 10% = $16.00. Adding everything together gives a weighted average contribution margin of $59.50 per unit.
This number shows the overall profitability of your product mix. Notice how the sales mix heavily influences the outcome. For instance, if you shift more sales toward the Pro Plan (with its strong margin), the weighted average margin increases, making it easier to hit profitability.
Allocating Break-Even Target Across Products
Once you’ve calculated the weighted average contribution margin, the next step is to use it to determine your total break-even point. Let’s say your startup has fixed costs of $11,900 per month. Using the formula:
Break-even point = Fixed Costs ÷ Weighted Average Contribution Margin
You get: $11,900 ÷ $59.50 = 200 total units per month.
Now, break this down by product using the sales mix:
- Basic Plan: 200 units × 60% = 120 units
- Pro Plan: 200 units × 30% = 60 units
- Enterprise Plan: 200 units × 10% = 20 units
This breakdown tells your sales team exactly how many of each plan they need to sell to cover costs. It also provides strategic insights. For example, if you’re falling short on Enterprise sales - closing only 10 deals instead of 20 - you’d need to sell significantly more Basic or Pro plans to make up the difference. However, because the Enterprise plan has a much higher contribution margin, achieving the same profitability through lower-tier plans would require a larger volume of sales.
The beauty of this method is its flexibility. As your sales mix shifts - say you sell more Pro plans than expected - you can quickly recalculate the weighted average and adjust your targets. Keeping a close eye on your actual sales mix versus these projections helps you stay on track and highlights when adjustments to pricing, marketing, or costs are needed to meet your break-even goals.
Tools to Simplify Break-Even Analysis
Now that we've covered the basics of break-even analysis and its calculations, let's look at how the right tools can make the process easier. Whether you're a hands-on founder or prefer automated solutions, there's an option that can match your startup's needs and budget.
Using Spreadsheets for Manual Calculations
If you like having control over every detail, Excel and Google Sheets are excellent choices for break-even calculations. These tools let you customize formulas, experiment with different scenarios, and keep everything transparent.
Here’s how it works: input your fixed costs, variable cost per unit, and selling price per unit into separate cells. Then calculate the contribution margin (selling price minus variable cost) and apply the formula:
Fixed Costs ÷ Contribution Margin
For example, if your fixed costs are $15,000, your selling price is $50, and your variable cost per unit is $5, your break-even point will be 334 units or $16,667 in revenue.
Want to test different scenarios? Use Excel's Goal Seek feature (found under Data > What-If Analysis > Goal Seek). This tool lets you adjust variables - like sales volume or pricing - to see how they affect your break-even point. It’s a quick way to explore how changes in costs or pricing might impact your business.
And if you’re new to break-even analysis, you can check out the U.S. Small Business Administration’s free online break-even calculator. It’s specifically designed for American startups, using familiar dollar formatting and business terms.

Using Break-Even Analysis for Business Planning
Break-even analysis isn’t just a one-time exercise; it’s a tool that should guide your broader business strategy. The insights you gain can directly shape your revenue goals, pricing decisions, and cost management strategies.
For instance, use your break-even point to set minimum sales targets. If breaking even requires selling 334 units, aim for 400-500 units to ensure a healthy profit margin.
When it comes to pricing strategies, break-even analysis helps you see the impact of price adjustments. For example, a 10% price increase might significantly lower the number of units you need to sell, while a price drop could push sales targets beyond what’s realistic.
The analysis also highlights when it’s time to focus on cost-cutting. If your break-even point demands more sales than your market can support, it’s a sign to revisit your cost structure. Look for ways to lower fixed costs or negotiate better rates with suppliers.
Finally, regular break-even analysis makes it easier to communicate financial milestones to investors and stakeholders. You can clearly outline your path to profitability, justify funding requests, and set realistic timelines for when your business will become self-sustaining.
Make it a habit to revisit your break-even calculations monthly or quarterly. As your business grows and market conditions shift, this practice ensures your financial strategy stays aligned with reality.

FAQs
How can break-even analysis help me set realistic sales goals for my startup?
Break-even analysis is a powerful way for startup founders to figure out the minimum revenue needed to cover their costs. By pinpointing your break-even point, you can set practical sales targets and gain a clear understanding of how much you need to sell to turn a profit.
Here’s the formula to calculate your break-even point:
Break-Even Point (Units) = Fixed Costs ÷ (Price per Unit - Variable Cost per Unit)
Let’s break it down with an example. Imagine your fixed costs are $10,000, your product sells for $50, and your variable cost per unit is $30. Using the formula, your break-even point would be 500 units. In simple terms, you’d need to sell at least 500 units to cover all your expenses.
To make this process easier, tools like Lucid Financials can be a game changer. They offer real-time financial insights, allowing you to stay focused on growing your business while keeping a close eye on your numbers.
