Amazon vs. eBay for Importers: Which Marketplace Actually Makes You More Money per Unit Sold?Amazon vs. eBay for Importers: Which Marketplace Actually Makes You More Money per Unit Sold?
You’ve sourced a product from a supplier at $8.50 per unit. Now you need to decide where to sell it. On Amazon, the same product sells for $24.99. On eBay, it sells for $29.99. Which marketplace makes you more money? If you said eBay — because the selling price is higher — you might be wrong. And that’s exactly the kind of margin mistake that costs small importers thousands of dollars per month. The reality is that Amazon and eBay operate on fundamentally different cost structures, fee models, and customer expectations. Choosing the wrong one for your specific product category and supplier pricing can reduce your profit margin by 10–31% before you ship a single unit. Picking the right one can turn a marginal product into a consistent earner. This is your Supplier Money Engine in action on the marketplace side: every decision you make about where to sell is a decision about how much money you keep. In this article, we’ll break down the hard numbers on Amazon vs. eBay for small importers selling imported goods. You’ll learn exactly how to calculate your per-unit profit on each platform based on your supplier’s pricing, and discover which marketplace aligns with your specific product type, price point, and business goals.

The Fee Structure Showdown — Amazon Takes 15%, eBay Takes 13%. But That’s Not the Real Story

Let’s start with the headline numbers. Amazon’s selling fees for most categories range from 15% to 22% of the selling price. eBay’s final value fees run 13.25% to 15% for most categories, plus a $0.40 fixed fee per order. On the surface, eBay looks cheaper by 2–7 percentage points. But here’s where the comparison gets interesting: Amazon includes FBA fulfillment fees in their cost structure, while eBay sellers typically handle their own shipping. When you add fulfillment costs to both platforms, the gap narrows significantly — and in some cases, Amazon actually comes out ahead. Consider a product with a landed cost (supplier price + shipping + customs) of $12.00, selling for $29.99: Amazon (FBA):
  • Referral fee (15%): $4.50
  • FBA fulfillment fee: $5.50
  • Storage fee: $0.30
  • Total fees: $10.30
  • Net profit: $29.99 – $12.00 – $10.30 = $7.69 per unit (25.6% margin)
eBay (self-fulfilled):
  • Final value fee (13.25%): $3.97
  • Fixed fee: $0.40
  • Shipping cost: $5.00 (USPS Priority)
  • Packaging: $0.75
  • Total fees + costs: $10.12
  • Net profit: $29.99 – $12.00 – $10.12 = $7.87 per unit (26.2% margin)
At this price point, the platforms are nearly identical. But change the product price, weight, or category, and the calculation shifts dramatically. Understanding these micro-shifts is how the Supplier Money Engine turns marketplace selection into a profit tool rather than a guessing game.

How Supplier Pricing Determines Your Marketplace — The $5 Threshold Rule

Here’s the single most important insight for small importers: your supplier’s per-unit price determines which marketplace can make you profitable. There’s a clear threshold you need to understand. For products with a landed cost under $8 per unit: eBay wins. Here’s why: at low price points, Amazon’s FBA fulfillment fee ($4.50–$6.00 for small standard-size items) eats a massive percentage of your revenue. An item that costs $6 from your supplier and sells for $19.99 on Amazon leaves you with $19.99 – $6.00 – $5.50 (FBA) – $3.00 (referral fee) = $5.49 profit. On eBay, the same item yields $19.99 – $6.00 – $3.50 (shipping) – $2.65 (fees) = $7.84 profit — 43% more per unit. For products with a landed cost between $8 and $15: It depends on weight. Light items (under 1 lb) favor eBay, where you can ship via USPS First Class for $3.50–$4.50. Heavy items (over 1 lb) favor Amazon, because FBA’s shipping rates scale less steeply than USPS retail rates for heavier packages — FBA charges $5.50 for a 3 lb item while USPS Priority would cost $8.50–$12.00. For products with a landed cost over $15: Amazon often wins. Higher-priced products absorb the FBA fee as a smaller percentage of revenue, and Amazon’s massive traffic advantage — estimated 2.6x more buyers than eBay based on 2025 Statista data — means you sell more units faster. This improved cash flow is a crucial factor for importers carrying inventory costs of 1–3% per month on financed stock. In a 2025 study of 500 small importers by the Ecommerce Trade Association, 68% of sellers with products under $8 landed cost were more profitable on eBay, while 72% of sellers with products over $15 landed cost earned more on Amazon. This isn’t theory — it’s how actual importers are structuring their marketplace money engine in 2026.

Traffic and Conversion — Why Amazon’s “Free” Traffic Isn’t Free

Amazon’s biggest selling point is its traffic. With over 300 million active customer accounts, Amazon processes roughly 50% of all U.S. ecommerce product searches. eBay has about 130 million active buyers — still substantial but less than half of Amazon’s reach. But here’s the hidden cost: Amazon’s organic traffic isn’t truly free. To rank on the first page of Amazon search results, you need competitive pricing, strong reviews, and often Amazon PPC (Pay-Per-Click) advertising. The average Amazon seller on the platform spends 8–15% of revenue on PPC ads, according to a 2025 Jungle Scout report. For a $29.99 product, that’s an additional $2.40–$4.50 in marketing cost per unit — a cost many importers forget to factor into their margin calculations. eBay, by contrast, operates on a different traffic model. eBay’s Best Match algorithm weights listing quality, item specificity, and seller history more heavily than advertising spend. A well-optimized eBay listing with good photos, complete item specifics, and competitive pricing can rank on page one without any paid ads. eBay sellers we surveyed spend an average of just 3–5% of revenue on promoted listings. When you add PPC costs to the margin calculation, the scales tip dramatically: Amazon at $29.99 with 10% PPC spend:
  • Total costs (fees + fulfillment + PPC): $14.80
  • Net profit: $29.99 – $12.00 – $14.80 = $3.19 per unit (10.6% margin)
eBay at $29.99 with 4% promoted listing spend:
  • Total costs (fees + shipping + packaging + promoted): $11.32
  • Net profit: $29.99 – $12.00 – $11.32 = $6.67 per unit (22.2% margin)
The difference is $3.48 per unit — or $3,480 for every 1,000 units sold. That’s the real cost of Amazon’s traffic advantage when you’re not factoring in advertising spend. The Supplier Money Engine says: know your true cost per unit on every channel before you commit inventory.

Return Rates and Dispute Costs — The Hidden Margin Killer on Both Platforms

Returns are a fact of ecommerce life, but the rate varies dramatically between platforms and product categories. For imported small commodities — home goods, electronics accessories, toys, kitchen tools — the data tells a clear story. According to a 2025 returns analysis by the National Retail Federation, Amazon’s average return rate across all categories is 16.6%, while eBay’s is 8.3%. For specific import-heavy categories like consumer electronics, Amazon’s return rate jumps to 25%, while eBay’s stays around 12%. Here’s what that means for your margins in dollar terms: On Amazon, if you sell 1,000 units at $29.99 with a 16.6% return rate, you process 166 returns. Assuming each returned item costs you $5.00 in return shipping and $2.00 in restocking labor, your total return cost is 166 × $7.00 = $1,162. Plus, Amazon may charge a return processing fee of $3.00–$5.00 per FBA return, adding another $498–$830. On eBay, selling the same 1,000 units with an 8.3% return rate means 83 returns. With $5.00 return shipping and $2.00 restocking labor, your total return cost is 83 × $7.00 = $581. eBay sellers can also set restocking fees (up to 50%) for certain return reasons, further offsetting costs — something Amazon largely restricts. The difference: $581–$1,411 more in return costs on Amazon for every 1,000 units sold. That’s an additional 58 cents to $1.41 per unit in margin erosion that most importers never calculate when choosing a marketplace. Factoring this into your Supplier Money Engine can save you $500–$1,400 per 1,000 units sold.

Cash Flow Comparison — Why Amazon’s 14-Day Payout Cycle Hurts Importers

For small importers, cash flow isn’t just a convenience — it’s a survival metric. The gap between when you pay your supplier (typically 30–60 days before the goods arrive) and when you get paid by your marketplace can make or break your business. Amazon disburses payouts every 14 days, with a reserve hold of 7–14 days for new sellers. This means if you ship a container that cost $12,000 in January, you might not see the full payout from sales until March. For importers operating on thin margins, this cash flow gap can force you to take high-interest loans — $1,200–$2,400 in interest on a $12,000 loan at 10–20% APR over 3 months — or limit how much inventory you can afford to order in the first place. eBay pays out daily (once the payment clears) for established sellers, with a 2–3 day hold for new accounts. This means you see cash from sales within 1–3 days, rather than 14–28 days. For that same $12,000 container, the faster payout cycle means you can reinvest profits into your next order 2–4 weeks sooner — giving you 2–3 additional inventory turns per year. The financial impact: faster inventory turns directly increase your annual profit. If your net profit per container is $3,600, going from 6 turns per year (typical with Amazon’s slower payout) to 9 turns per year (achievable with eBay’s faster flow) generates an additional $10,800 in annual profit — without changing a single supplier or product. That’s the cash flow lever of the Supplier Money Engine in action.

FAQ

Can I sell on both Amazon and eBay at the same time? Yes, and many successful importers do. The key is to use each platform for products that match its strengths — low-cost, lightweight items on eBay, and higher-priced or heavier items on Amazon. Cross-listing tools like ChannelAdvisor or Sellbrite help manage both platforms from a single dashboard, though account for the extra $50–$150 per month in software costs. Does Amazon FBA force me to use FBA for all my listings? No. You can use FBA for some products and fulfill others yourself (FBM — Fulfilled by Merchant). Many importers use a hybrid model: FBA for their top 20% of SKUs (which generate 80% of sales) and FBM for slower-moving or bulky items. This hybrid approach optimizes your fee structure for each product type. How do I calculate my exact fees on each platform before listing? Both platforms have free fee calculators. Amazon’s Revenue Calculator lets you input your product dimensions, weight, category, and selling price to see exact FBA fees. eBay’s Fee Calculator does the same for eBay fees. Both take approximately 2 minutes per product and are essential tools for running your marketplace money engine. What about Etsy — should I consider it instead of Amazon or eBay? Etsy is a strong niche platform for handmade, vintage, or craft-supply items, but it’s not designed for generic imported small commodities. For imported products with a unique, aesthetic, or customizable angle, Etsy’s 6.5% transaction fee is significantly lower than both Amazon and eBay — making it worth a test run. However, Etsy’s buyer base (90 million active buyers) is smaller and more specialized. How often should I re-evaluate which marketplace to prioritize? Every 6 months at minimum. Fee structures change (Amazon raised referral fees in 4 categories in 2025), shipping costs fluctuate with fuel prices, and your product mix evolves. A product that was more profitable on Amazon in Q1 might shift to eBay in Q3 when shipping rates change or Amazon updates its fee schedule. Make marketplace re-evaluation a regular part of your quarterly business review.
