【Organized with MECE】What Is the Amazon Fee List? The Basic Cost Structure Every EC Beginner Must Learn First
When considering selling on Amazon, the biggest hurdle is understanding the complex "fee" structure. To accurately calculate profit margins, it's essential to understand the structure from a MECE (Mutually Exclusive, Collectively Exhaustive) perspective, rather than just listing costs. This article organizes the Amazon fee list and thoroughly explains the basic cost structure that every EC beginner must learn first.

1. The Big Picture of Amazon Fees: MECE Breakdown of Fixed and Variable Costs
The first step to understanding Amazon's cost structure is dividing expenses into "fixed costs for account maintenance" and "variable costs linked to sales." Failing to organize this before starting operations leads to the "sales are growing but profits aren't" cash flow trap.
- Fixed Costs: Expenses incurred regardless of sales volume, such as the Professional selling plan (monthly fee of ¥4,900).
- Variable Costs: Expenses per unit sold, including referral fees, category closing fees, and FBA fulfillment fees.
2. Referral Fees: Category-Specific Characteristics
Amazon's referral fees range from approximately 8% to 15% depending on the product category. For example, electronics are at a lower 8%, while apparel and media are set at 15%. Choosing the wrong category can lead to unexpected cost increases.
3. FBA Fees vs. Self-Fulfillment Break-Even Point
When using FBA (Fulfillment by Amazon), inventory storage fees and fulfillment fees apply. The "inventory turnover rate" is particularly important—products that remain unsold for extended periods see storage costs erode profits. On the other hand, FBA grants the "Prime badge," which improves CVR (conversion rate), a benefit worth considering.
4. Profit Maximization Through Unit Economics
What ultimately matters is the profitability per unit—unit economics. Always keep visible the "contribution profit" after subtracting "cost of goods," "Amazon fees," and "advertising costs (ACOS)" from the selling price. If this is positive, you can accelerate advertising investment to trigger the "Flywheel effect."
Frequently Asked Questions
- Q. Which is more cost-effective: Individual or Professional selling plan fees?
- A. If you sell 50 or more items per month, the Professional plan becomes cheaper even after paying the fixed fee. Considering the advertising features only available with the Professional plan, it is recommended for serious operations.
- Q. What is a category closing fee?
- A. It is a fixed fee separate from the referral fee that only applies to media products such as books, music, videos, and DVDs. Be sure to include it in your calculations if you handle media products.
