Understanding Break-Even Point
Break-even point is the exact number of units you need to sell (or revenue you need to generate) to cover all your costs—with $0 profit or loss. Beyond break-even, every sale becomes profit. Below break-even, every sale costs you money.
Why it matters: Break-even analysis tells you the minimum sales volume needed to survive. If you can't reach break-even with realistic sales projections, the product isn't viable. If you exceed break-even by 50%, your margins are comfortable.
Formula: Units to Break Even = Fixed Costs ÷ (Sale Price - Variable Costs per Unit)
Break-Even by Units
How many units must you sell to break even?
Rent, salaries, insurance, software, etc. (doesn't change per unit)
What customers pay for one unit
COGS + fees (changes with each unit)
Fixed Costs (Monthly):
$0.00
Sale Price per Unit:
$0.00
Variable Cost per Unit:
$0.00
Contribution Margin:
$0.00
Break-Even Units (Monthly):
0
Annual Break-Even: 0 units/year (0 units/day)
Real Examples
Example 1: Amazon FBA Product
- Fixed Costs (monthly): $1,000 (rent, utilities, software)
- Sale Price: $25/unit
- Variable Costs: $10/unit (COGS + fees)
- Contribution Margin: $15/unit
Break-Even = $1,000 ÷ $15 = 67 units/month (or ~2 units/day)
Annually: 804 units
Annually: 804 units
Example 2: Low-Margin Product (RISKY)
- Fixed Costs (monthly): $3,000
- Sale Price: $15/unit
- Variable Costs: $12/unit
- Contribution Margin: $3/unit (only 20%!)
Break-Even = $3,000 ÷ $3 = 1,000 units/month (33 units/day!)
This is very risky. One bad month = losses.
This is very risky. One bad month = losses.
Example 3: High-Margin Product (SAFE)
- Fixed Costs (monthly): $2,500
- Sale Price: $100/unit
- Variable Costs: $30/unit
- Contribution Margin: $70/unit (70% margin!)
Break-Even = $2,500 ÷ $70 = 36 units/month (1 unit/day)
Very safe. Easy to exceed break-even.
Very safe. Easy to exceed break-even.
Key Insights
- Lower break-even = lower risk: High-margin products with low break-even points survive market downturns better.
- Contribution margin is key: Every dollar of contribution margin goes toward covering fixed costs. Higher CM = better.
- Fixed costs kill new products: If you can't reach break-even with realistic sales, kill the product. Don't throw good money after bad.
- Margin of safety matters: If your projected sales = break-even, you have NO safety margin. Aim for 30%+ above break-even.
