Break-Even Analysis for Ecommerce Sellers
Break-even analysis answers the most important question in ecommerce: how much do I need to sell to cover my costs?
Why Break-Even Matters
Without knowing your break-even point, you're flying blind. You might think a product is profitable when it's actually losing money, or pass up good products because you don't know the math.
The Basic Formula
Break-Even Price = Total Costs ÷ (1 − Fee Rate)
Where Total Costs include COGS, shipping, and fixed costs per unit.
Step-by-Step: Break-Even Price
- Calculate total variable costs per unit
- Product cost
- Shipping to customer
- Payment processing fees (2.9% + $0.30)
- Platform fees (if applicable)
- Add fixed costs per unit
- Monthly overhead ÷ expected monthly sales
- Advertising cost per unit (if running ads)
- Apply the formula
Break-Even Price = Total Costs ÷ (1 − Platform Fee Rate)
Example: Dropshipping Product
| Cost Item | Amount |
|---|---|
| Product cost | $8.00 |
| Shipping | $3.00 |
| Payment processing (3%) | $0.81 |
| Platform fee (15%) | Included in formula |
| Total variable costs | $11.81 |
Break-Even Price = $11.81 ÷ (1 − 0.15) = $13.90
You must sell at $13.90 or higher to break even.
Break-Even Volume
If you have fixed costs (software, tools, salary):
Break-Even Volume = Fixed Costs ÷ Contribution Margin per Unit
Where Contribution Margin = Selling Price − Variable Costs
Break-Even Ad Spend
Max Ad Spend per Sale = Selling Price − All Other Costs
If you spend more on ads than this, you're losing money.
