# Break-Even Point

## Quick Definition
The point where total revenue equals total costs, meaning the business is neither profitable nor losing money.

## What is Break-Even Point?
Break-even point is where total revenue equals total costs, meaning you're neither making nor losing money. It's the threshold you must cross to become profitable.

For startups, break-even represents a critical milestone. Before break-even, you're burning cash and dependent on external funding. After break-even, you control your own destiny.

## Why Break-Even Matters
Knowing your break-even point helps you set targets and understand how far you are from profitability. It also reveals how changes in pricing, costs, or volume affect your path to profit.

Break-even analysis is essential for fundraising. Investors want to know when you'll become self-sustaining and how much capital is needed to get there.

## How to Calculate Break-Even Point Step by Step
**Step 1: Total your monthly fixed costs.** These are costs you pay regardless of customer count:
- Engineering salaries: $55,000
- Office/remote stipends: $5,000
- Software tools: $4,000
- Insurance/legal/accounting: $3,000
- Founders' salaries: $15,000
- **Total fixed costs: $82,000/month**

**Step 2: Calculate [contribution margin](/content/terms/contribution-margin/index.html) per customer.** Revenue minus variable costs per customer.
- Average subscription: $350/month
- Variable costs per customer (hosting, support, payment processing): $55
- **Contribution margin: $295/customer**

**Step 3: Divide fixed costs by contribution margin.**
- **Break-even = $82,000 ÷ $295 = 278 customers**

**Step 4: Calculate break-even in revenue terms.**
- Contribution margin % = $295 ÷ $350 = 84.3%
- **Break-even revenue = $82,000 ÷ 0.843 = $97,273/month MRR**

**Step 5: Plot your timeline to break-even.** If you're adding 15 net new customers per month:
- Current customers: 180
- Gap: 98 customers
- **Months to break-even: 98 ÷ 15 = ~6.5 months**

This is critical for runway planning. If break-even is further out than your runway, you need to raise, cut costs, or accelerate growth.

**Step 6: Sensitivity analysis.** Test how changes affect break-even:
- Price increase to $400/mo → break-even drops to 238 customers
- Adding one engineer ($12K/mo) → break-even increases to 319 customers
- Reducing churn by 1% → faster net customer growth → break-even 2 months sooner

**Common mistakes founders make:**
- Forgetting semi-variable costs that step up (support team grows every 100 customers)
- Using current burn rate instead of properly separating fixed vs variable costs
- Not updating break-even as costs change (every new hire moves the target)
- Ignoring that break-even is a moving target — it changes as you scale

## Calculating Break-Even
Divide fixed costs by contribution margin per unit. If fixed costs are $50K/month and each customer contributes $500/month, you need 100 customers to break even.

**Formula**
- Break-Even (units) = Fixed Costs ÷ Contribution Margin per Unit
- Break-Even (revenue) = Fixed Costs ÷ Contribution Margin %

**Example**
Your business economics:
- Fixed costs: $100,000/month
- Average revenue per customer: $500/month
- Variable cost per customer: $100/month
- Contribution margin: $400/customer

**Break-Even = $100,000 ÷ $400 = 250 customers**

You need 250 paying customers to cover all fixed costs. Customer 251 starts generating profit.
