Quick Answer
Why Most Amazon Sellers Don't Know Their True Profit Margin
Jungle Scout 2025 State of the Amazon Seller Report found that 43% of Amazon sellers could not accurately estimate their profit margin within 5 percentage points. Fees are fragmented across referral costs, FBA fees, storage, advertising, and returns — making the true picture difficult to see. This guide does the calculation.
Complete Amazon Fee Breakdown (2026)
1. Referral Fees — The Baseline
| Category | Referral Fee % | Min Fee |
|---|---|---|
| Apparel & Clothing | 17% | $0.30 |
| Beauty & Personal Care | 8–15% | $0.30 |
| Electronics | 8% | $0.30 |
| Home & Kitchen | 15% | $0.30 |
| Jewellery | 20% | $2.00 |
| Handmade Products | 15% | $1.00 |
| Most Other Categories | 15% avg | $0.30 |
2. FBA Fulfilment Fees
Required for Prime eligibility. FBA fees range from $3.22 for small standard items to $8.25+ for large standard. For typical products in popular categories — candles, jewellery, clothing under 12oz — expect $3.50–$4.50 per unit.
3. Monthly Storage Fees
$0.78/cubic ft January–September, rising to $2.40/cubic ft October–December. Long-term storage (items held 365+ days) costs $6.90/cubic ft — making slow-moving inventory expensive to hold.
4. Amazon Advertising (Sponsored Products)
Marketplace Pulse 2025 data shows the average seller now spends 15–25% of revenue on advertising. Organic ranking drops 30–50% within 60 days without advertising spend. In practice, advertising is not optional for most categories — it is a cost of doing business on Amazon.
5. Professional Seller Account
$39.99/month flat fee required for sellers with 40+ sales per month (essentially all serious sellers).
6. Returns and Return Processing Fees
Amazon introduced return processing fees in 2024 for high-return categories including apparel (20–40% return rates). Typical cost: $1–$5 per returned item, which adds up quickly for clothing sellers.

| Advertising (18%) | $5,000 × 18% | $900 |
| Professional Account | flat | $40 |
| Returns (5% rate, $3/unit) | 5 × $3 | $15 |
| TOTAL COSTS | — | $2,213 |
| NET REVENUE KEPT | — | $2,787 (55.7% of gross) |

The Difference Over 12 Months
What Amazon Gives You That Your Own Store Doesn't
- Immediate access to 300M+ active customer accounts
- Built-in trust signals (Prime badge, Amazon brand recognition)
- Prime eligibility for fast shipping expectations
- Product discovery from active buyers browsing Amazon
Amazon buys you an audience but charges 40–60% of your revenue. Your own store earns you an audience over time and costs 4–10% of revenue. The trade-off is immediate traffic vs. long-term margin.
The Hybrid Strategy: Amazon + Your Own Store
Many successful sellers run both simultaneously. Include a card in Amazon orders directing customers to your ExaStore for repeat purchases. Use your ExaStore email list to re-engage past customers. Gradually shift repeat purchases off Amazon — where you pay 40–60% per sale — onto ExaStore, where you pay 3–5%.
Frequently Asked Questions
Can I sell on Amazon and ExaStore simultaneously?
Yes — this is the hybrid strategy most advanced sellers use. Amazon provides discovery; ExaStore provides margin on direct and repeat sales.
Does ExaStore replace Amazon advertising?
ExaStore does not provide Amazon-style marketplace advertising. However, sellers use Instagram, Facebook, and Google Ads to drive traffic to their ExaStore — where the 0% commission means advertising ROI is dramatically higher than on Amazon.
What about Amazon Brand Registry?
Amazon Brand Registry provides trademark protection and enhanced listings on Amazon. You can maintain Brand Registry while building your ExaStore in parallel — the two are independent.
