Break-Even Analysis

📌 What Is a Break-Even Analysis?

A break-even analysis is one of the most fundamental calculations in business finance. It identifies the exact point at which your total revenue equals your total costs — the moment you stop losing money and start making a profit. Every dollar earned beyond the break-even point is pure profit; every dollar short of it is a loss.

Before launching any product or service, calculating the break-even point forces you to confront some uncomfortable but important questions: Is your price high enough? Are your costs too high? How many units can you realistically sell each month? The math often reveals that a business idea that sounds profitable on paper isn't viable at a realistic sales volume — and knowing that before you invest your savings is invaluable.

👤 Who Is This Calculator For?

• Entrepreneurs planning a new product launch who need to validate pricing before manufacturing
• Small business owners evaluating whether to add a new product line or service offering
• Freelancers determining the minimum number of projects or hours needed to cover monthly overhead
• Restaurant and retail owners analyzing menu item or product profitability
• Anyone writing a business plan who needs a break-even analysis section for investors or lenders

🛠️ How to Use This Calculator

1. Enter Fixed Costs: Input all monthly expenses that remain constant regardless of how much you produce or sell — rent, insurance, salaried employee wages, software subscriptions, loan payments. These costs exist even if you sell zero units.
2. Enter Variable Cost per Unit: The cost to produce or deliver a single unit — raw materials, shipping, packaging, payment processing fees, direct labor per unit. These scale directly with sales volume.
3. Enter Sale Price per Unit: What you charge the customer per unit. If you sell at different price points, use a weighted average.
4. View Break-Even Point: The calculator shows how many units must be sold monthly to cover all costs, and the total revenue that represents.

📐 The Formula

💡 Real-World Example

Sarah wants to sell custom T-shirts. Her fixed costs (Shopify subscription, design software, marketing tools) are $500/month. Each shirt costs $10 to make (variable cost — blank shirt, printing, packaging), and she sells them for $25.

Contribution margin = $25 − $10 = $15. Break-even units = $500 ÷ $15 = 33.3 → rounded up to 34 shirts. Break-even revenue = 34 × $25 = $850/month.

Sarah must sell 34 shirts every month just to cover her costs. Her 35th shirt earns $15 in pure profit. If she can sell 60 shirts a month, her monthly profit is (60 − 33.3) × $15 = $400.

⚠️ Limitations of This Calculator

• This model assumes a single product at a fixed price. Businesses with multiple products at different price points and variable costs need a more complex blended analysis.
• Variable costs are assumed constant per unit. In reality, bulk purchasing may lower per-unit costs at higher volumes (economies of scale), which improves profitability beyond what this model shows.
• This analysis does not account for taxes, interest on business debt, or depreciation of equipment.
• Break-even is a minimum threshold — it does not indicate a healthy, sustainable business. Most businesses need to target 2x–5x their break-even volume to generate meaningful profit after owner compensation.
