The Core Question
Break-even analysis answers: "How many units do I need to sell to cover all my costs?" Below break-even = losing money. Above it = every sale is profit.
🧮 The Break-Even Formula
The Formula
Break-Even Units = Fixed Costs ÷ (Price Per Unit − Variable Cost Per Unit)The bottom part — (Price − Variable Cost) — is the contribution margin.
📊 Fixed vs. Variable Costs
Fixed Costs (same regardless of sales)
Rent:$3,000/mo
Salaries:$8,000/mo
Insurance:$500/mo
Software:$300/mo
Total Fixed
$11,800
/month
Variable Costs (per unit)
Materials:$5/unit
Packaging:$2/unit
Shipping:$3/unit
Total Variable
$10
/unit
☕ Real Example: Coffee Shop
| Item | Value |
|---|---|
| Fixed costs | $8,000/month |
| Avg coffee price | $5.50 |
| Variable cost per cup | $1.50 |
| Contribution margin | $4.00 |
| Break-even | 2,000 cups/month |

Cups per day to break even

Cups per hour (12hr day)
2,750
Cups for $3K/mo profit
Profit Target Formula
Units = (Fixed Costs + Desired Profit) ÷ Contribution MarginFor $3K profit: ($8K + $3K) ÷ $4 = 2,750 cups/month
Common Mistakes
Forgetting hidden fixed costs (loan payments, marketing), underestimating variable costs (CC fees, waste), using revenue instead of contribution margin, and ignoring time — can you survive until break-even?
