Your net profit as a percentage of selling price to evaluate product viability.
Return on investment relative to total costs to measure efficiency.
Minimum selling price required to avoid losses on each transaction.

Frequently Asked Questions
What costs should I include in "Other Costs"?
Include any per-unit expenses not covered by the other fields:
- Custom packaging materials and branded inserts
- Product inspection or quality control fees
- Return handling and restocking costs
- Insurance or protection plans
- Special handling or preparation fees
How is the breakeven price calculated?
The breakeven price is the minimum selling price at which your net profit equals zero. It accounts for:
- All fixed per-unit costs (product, shipping, ads, other)
- Percentage-based fees (platform commission and payment processing)
- Fixed payment processing fees (e.g., $0.30 per transaction)
What's the difference between profit margin and ROI?
These two metrics measure profitability from different perspectives:
Revenue-Based Metric
Formula: (Net Profit ÷ Selling Price) × 100
Tells you: What fraction of each sale is actual profit
Example: $10 profit on $50 sale = 20% margin
Cost-Based Metric
Formula: (Net Profit ÷ Total Costs) × 100
Tells you: How much you earn relative to what you spend
Example: $10 profit on $40 costs = 25% ROI
Both metrics are important — profit margin shows pricing efficiency, while ROI shows investment efficiency.
Why does Amazon FBA have 0% payment processing fee?
Amazon handles payment processing as part of their integrated referral fee structure. Here's how it differs from other platforms:
| Platform | Marketplace Fee | Payment Processing | Total Fee Structure |
|---|---|---|---|
| Amazon FBA | 15% referral fee | Included | All-in-one |
| Shopify | None | 2.9% + $0.30 | Separate |
| AliExpress | None | 2.9% + $0.30 | Separate |
How should I estimate advertising cost per unit?
Calculate your advertising cost per unit by dividing total ad spend by units sold:
Example: If you spend $300 on ads and sell 100 units, your advertising cost per unit is $3.
