Break-Even Analysis: How to Calculate Your Break-Even Point [Examples]

What Is a Break-Even Analysis?

A break-even analysis calculates the point where total revenue equals total costs — no profit, no loss. Below that point, you're losing money on every operating day. Above it, every additional sale generates profit.

The concept is simple, but the implications are powerful:

• New business planning — how many customers do you need before the business sustains itself?
• Pricing decisions — if you raise prices 10%, how does that change when you break even?
• New product launches — how many units must you sell to justify the development investment?
• Lease-vs-buy decisions — at what volume does owning equipment become cheaper than leasing?

Break-even analysis won't tell you if a business will succeed — that depends on demand, competition, and execution. But it will tell you what success requires in concrete numbers.

The Break-Even Formula

There are three versions of the formula. They all calculate the same thing from different angles.

Formula 1: Break-Even in Units

Break-Even Units = Fixed Costs ÷ Contribution Margin per Unit

Where: Contribution Margin = Selling Price - Variable Cost per Unit

Example: You sell software licenses at $200/license. Each license costs $50 in hosting and support (variable). Your fixed costs are $30,000/month (salaries, office, tools).

Contribution Margin = $200 - $50 = $150
Break-Even = $30,000 ÷ $150 = 200 licenses per month

You need to sell 200 licenses per month to break even.

Formula 2: Break-Even in Revenue

Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio

Where: Contribution Margin Ratio = Contribution Margin ÷ Selling Price

Same example:

CM Ratio = $150 ÷ $200 = 75%
Break-Even Revenue = $30,000 ÷ 0.75 = $40,000/month

You need $40,000 in monthly revenue to break even. This version is useful when you sell multiple products at different prices.

Formula 3: Break-Even with Target Profit

Units for Target Profit = (Fixed Costs + Target Profit) ÷ Contribution Margin

Same example, targeting $15,000 monthly profit:

Units = ($30,000 + $15,000) ÷ $150 = 300 licenses per month

You need 300 licenses to both cover costs and generate your target profit.

Worked Example 1: Product Business

Scenario: An e-commerce company selling ergonomic office chairs.

Fixed Costs (monthly):

Variable Costs (per unit):

Selling Price: $399

Break-Even Calculation:

Contribution Margin = $399 - $255 = $144 per chair
Break-Even Units = $29,000 ÷ $144 = 202 chairs per month
Break-Even Revenue = 202 × $399 = $80,598 per month

The company needs to sell 202 chairs per month ($80,598 revenue) to break even. At 250 chairs, they'd generate $6,912 monthly profit. At 300 chairs, $14,112.

Worked Example 2: Service Business

Scenario: An IT consulting firm offering cybersecurity assessments.

Fixed Costs (monthly):

Variable Costs (per engagement):

Average Engagement Price: $8,500

Break-Even Calculation:

Contribution Margin = $8,500 - $2,000 = $6,500 per engagement
Break-Even = $37,700 ÷ $6,500 = 5.8 engagements per month

The firm needs to complete 6 assessments per month to break even. With 2 consultants each doing ~3 per month, this is achievable — but leaves almost no profit margin. At 8 assessments, they'd generate $14,300 monthly profit.

How to Build a Sensitivity Analysis

A single break-even number gives false precision. Real businesses face cost fluctuations and price pressure. A sensitivity analysis shows how your break-even changes under different scenarios.

Method: Create a "What-If" Table

Using the chair business example, calculate break-even under different price and cost assumptions:

The worst case is sobering: a 10% price drop combined with a 10% cost increase nearly doubles the break-even point (202 → 372). This analysis helps you answer: "What's the minimum price we can accept?" and "How much cost increase can we absorb?"

When to Use Break-Even Analysis

Break-even isn't just for startups. Here are six situations where established businesses should run the numbers:

1. New product launch — how many units to recoup development and marketing costs?
2. Pricing changes — if we drop prices 15%, how much volume increase do we need to maintain revenue?
3. Make-vs-buy decisions — at what volume does manufacturing in-house beat outsourcing?
4. Expansion decisions — how much revenue does a new location need to justify the lease?
5. Cost reduction initiatives — if we cut $50K in fixed costs, how does that change our break-even?
6. Investor conversations — when will this business become self-sustaining?

Frequently Asked Questions

What's a good break-even period for a new business?

Most investors and lenders expect a new business to break even within 12-18 months. SaaS businesses typically target 18-24 months because of high upfront customer acquisition costs. Retail and e-commerce businesses should aim for 6-12 months. If your analysis shows break-even beyond 24 months, you either need more capital, lower costs, or a higher price point. The break-even period also determines how much cash runway you need — if break-even is at month 18, you need at least 20-22 months of cash on hand.

What's the difference between break-even and payback period?

Break-even tells you when ongoing revenue covers ongoing costs — it's about operational sustainability. Payback period tells you when cumulative profits recover the initial investment — it's about investment return. A business might break even operationally in month 6 but not pay back the initial $200K investment until month 24. Both matter, but for different decisions: break-even for pricing and operations, payback for investment justification.

How do I calculate break-even for multiple products?

Use the weighted average contribution margin. Multiply each product's contribution margin by its sales mix percentage, then sum them. Example: if Product A ($50 CM) is 60% of sales and Product B ($30 CM) is 40%, the weighted CM is ($50 × 0.60) + ($30 × 0.40) = $42. Then divide total fixed costs by $42 to get the break-even in total units. This works when sales mix is relatively stable.

Should I include depreciation in fixed costs?

Include depreciation only if you're analyzing accounting profitability. For cash-based break-even (when will cash flow positive?), exclude depreciation because it's a non-cash expense. For financial statement break-even, include it. Most operational decisions use cash-based break-even because the question is "when do we stop needing external funding?" not "when do our books show a profit?"

How accurate is break-even analysis?

Break-even analysis is a planning tool, not a prediction. Its accuracy depends on how well you estimate fixed costs, variable costs, and selling price. The sensitivity analysis (what-if scenarios) is more valuable than the single break-even number because it shows the range of outcomes. Update your analysis monthly with actual costs and prices — the break-even point shifts as real data replaces estimates.

What if my break-even point seems unreachable?

If the math shows you need 500 units per month but your market can only absorb 200, you have a fundamental business model problem. Your options: raise the price (increase contribution margin), reduce variable costs (find cheaper suppliers, optimize shipping), reduce fixed costs (smaller office, fewer staff, outsource), or pivot to a different product/market with better economics. Don't ignore bad break-even math — it's telling you something important about viability.
