Break-Even Analysis

When to Use This Skill

Use this skill when you need to:

• Calculate how many units or sales you need to break even
• Analyze fixed vs. variable costs to find the break-even point
• Model break-even scenarios for different pricing or cost structures
• Evaluate the viability of a new product, service, or business

DO NOT use this skill for full financial projections or pricing strategy. This is specifically for determining the break-even point.

Core Principle

BREAK-EVEN IS THE MINIMUM VIABLE NUMBER — IT TELLS YOU THE FLOOR, NOT THE GOAL. IF YOU CANNOT REACH BREAK-EVEN, THE BUSINESS MODEL NEEDS TO CHANGE BEFORE ANYTHING ELSE.

Phase 1: Cost Inputs

Required Inputs

GATE: Do not proceed without price, variable cost, and fixed costs.

Phase 2: Break-Even Calculation

## Break-Even Analysis: [Product/Service]

### Cost Structure
| Category | Amount |
|----------|--------|
| Selling price per unit | $[X] |
| Variable cost per unit | $[X] |
| **Contribution margin per unit** | **$[X]** |
| **Contribution margin %** | **[X]%** |
| Monthly fixed costs | $[X] |

### Break-Even Point
| Metric | Value | Formula |
|--------|-------|---------|
| **Break-even units (monthly)** | **[X] units** | Fixed costs / Contribution margin |
| **Break-even revenue (monthly)** | **$[X]** | Break-even units x Price |
| Break-even units (annual) | [X] units | Monthly x 12 |
| Break-even revenue (annual) | $[X] | Monthly x 12 |
| Units per day needed | [X] | Monthly / 30 |
| Units per week needed | [X] | Monthly / 4.3 |

### Margin of Safety
At current sales of [X] units/month:
| Metric | Value |
|--------|-------|
| Current monthly units | [X] |
| Break-even units | [X] |
| Margin of safety (units) | [X] |
| Margin of safety (%) | [X]% |

Phase 3: Scenario Modeling

## Scenario Analysis

### Price Sensitivity
| Price Point | Contribution Margin | Break-Even Units | Break-Even Revenue |
|------------|--------------------|-----------------|--------------------|
| $[X] (-20%) | $[X] | [X] | $[X] |
| $[X] (-10%) | $[X] | [X] | $[X] |
| **$[X] (current)** | **$[X]** | **[X]** | **$[X]** |
| $[X] (+10%) | $[X] | [X] | $[X] |
| $[X] (+20%) | $[X] | [X] | $[X] |

### Fixed Cost Scenarios
| Scenario | Monthly Fixed | Break-Even Units | Notes |
|----------|-------------|-----------------|-------|
| Lean (cut non-essentials) | $[X] | [X] | [What gets cut] |
| **Current** | **$[X]** | **[X]** | |
| Growth (add hire/tool) | $[X] | [X] | [What gets added] |

### Variable Cost Scenarios
| Scenario | Variable Cost/Unit | Break-Even Units |
|----------|-------------------|-----------------|
| Optimized (reduce COGS) | $[X] | [X] |
| **Current** | **$[X]** | **[X]** |
| Increased (higher quality) | $[X] | [X] |

Phase 4: Action Plan

## Recommendations

### Path to Break-Even
- Current monthly sales: [X] units
- Break-even target: [X] units
- Gap: [X] units ([X]% increase needed)

### Fastest Levers

2. **[Lever]** — [Impact]
3. **[Lever]** — [Impact]

### Timeline to Break-Even
At [X]% monthly growth rate: [X] months to reach break-even volume.

Example: Online Course ($197 price)

Costs: Variable $8/sale (processing + hosting). Fixed $3,200/month (software, ads, contractors). Contribution margin: $189/sale.

Break-even: 17 sales/month ($3,349/month revenue). At current 12 sales/month, need 42% more sales. At 10% monthly growth, break-even in 4 months.

Scenario: If price increases to $247, break-even drops to 13.4 sales/month — already profitable at current volume.

Anti-Patterns

• Forgetting hidden variable costs — payment processing fees, shipping, packaging, and platform commissions are variable costs. Include them all.
• Treating owner's salary as optional — if you plan to pay yourself, include it in fixed costs. A "profitable" business that does not pay the owner is not profitable.
• Static analysis only — always include at least 3 scenarios (price change, cost change, volume change).
• Ignoring the timeline — break-even in 2 months is great. Break-even in 24 months may mean you run out of cash first.
• Assuming linear scaling — at high volumes, variable costs may change (bulk discounts or additional infrastructure). Note the volume range where your numbers hold.

Recovery

• Break-even seems unreachable: Show which single change (price increase, cost cut, or additional revenue stream) has the biggest impact. Sometimes a 15% price increase changes everything.
• Multiple products: Calculate break-even per product, then create a blended analysis using the weighted average contribution margin.
• Service business (no clear "unit"): Define the unit as one client, one project, or one month of service. Calculate based on that.
• Pre-launch (no sales data): Use the break-even analysis to set targets. "You need X sales/month at $Y price to cover costs" becomes the launch goal.
