Multi-Channel Fee Comparison Calculator

About the Multi-Channel Fee Comparison Calculator

Every e-commerce channel has a different fee structure, and the most profitable channel depends on your product, price point, fulfillment path, and cost structure. This worksheet uses built-in baseline assumptions for Amazon FBA, Amazon FBM, eBay, Etsy, Shopify, Walmart, and TikTok Shop so you can compare margin outcomes side by side.

Enter your product details once, and see how those built-in assumptions affect net profit on each platform. The goal is quick comparison, not a substitute for each marketplace's own revenue calculator or fee schedule.

Use This calculator when deciding where to list a product, evaluating whether to expand to additional channels, or reviewing a multi-channel strategy. Before making a final pricing decision, confirm category-specific fees, payment charges, fulfillment costs, and promotional deductions in each seller portal.

When This Page Helps

Different products are profitable on different channels. A product that barely breaks even on Amazon might work better on Etsy or your Shopify store. This calculator reduces guesswork by showing a side-by-side worksheet across seven channels from one set of product inputs.

How to Use the Inputs

1. Enter your product selling price.
2. Enter the cost of goods (COGS) per unit.
3. Enter the shipping cost to customer (if relevant).
4. The calculator applies the baseline fee assumptions used on this page automatically.
5. Compare net profit and margin across all 7 channels.
6. Use the result as a comparison worksheet, then confirm exact fees in the platform you plan to use.

Example Calculation

Tips & Best Practices

• The cheapest channel isn't always the most profitable — consider traffic, conversion rate, and volume.
• Amazon FBA has the highest fees but often the highest sales volume due to Prime eligibility.
• Your own Shopify store has the lowest fees but requires you to drive all traffic.
• List on multiple channels but prioritize inventory and ad spend on the highest-volume channel.
• Use platform-native fee tools before listing products with thin margins.
• Review channel profitability regularly because marketplaces change fee schedules, promos, and fulfillment charges.

Channel Fee Assumptions Used on This Page

This worksheet uses a simplified fee model so you can compare the impact of different marketplaces with one set of product inputs. The built-in assumptions use broad seller-facing platform baselines such as Amazon referral fees, a simple FBA placeholder cost, eBay final value fees, Etsy listing and transaction fees, Shopify checkout fees, Walmart referral fees, and a TikTok Shop placeholder model. Those assumptions are useful for fast screening, but they do not cover every category, return charge, ad fee, promo deduction, or fulfillment rule.

Choosing Your Primary Channel

Your primary channel should have: (1) the strongest monthly profit potential, (2) product-market fit for your category, (3) manageable competitive pressure, and (4) alignment with your brand and fulfillment strategy. Don't choose based solely on the lowest fees — traffic, conversion rate, refund rate, and operational overhead matter just as much.

Multi-Channel Inventory Management

Selling on multiple channels requires synchronized inventory to avoid overselling. Solutions range from spreadsheets for a very small catalog to dedicated software for larger multi-channel operations. If you use marketplace fulfillment services, model those costs separately because they can materially change the ranking shown in a simple fee worksheet.

Frequently Asked Questions

• Which marketplace has the lowest fees?

  A self-hosted storefront or a Shopify store with Shopify Payments often has the lowest direct checkout cost. Among marketplaces, the answer depends on category, plan, and fulfillment method. Use this page to compare baseline assumptions, then confirm the exact seller fees in the marketplace documentation for your category.

• Should I sell on Amazon or Shopify?

  Both can make sense. Amazon provides built-in traffic but usually carries more fees and fulfillment constraints. Shopify gives you more control over brand and checkout economics, but you have to generate your own traffic. The better choice depends on whether you value reach, control, repeat-customer economics, or marketplace convenience most.

• Is eBay still worth selling on?

  Yes, for many categories. eBay remains useful for electronics, collectibles, auto parts, refurbished goods, and fashion. But the right answer depends on category fit, return rates, ad spend, shipping workflow, and the exact fee schedule that applies to your seller account.

• What about Walmart Marketplace?

  Walmart Marketplace can be attractive because it has no monthly subscription fee and category-based referral fees. However, traffic, category fit, and the application process differ from Amazon, Etsy, or Shopify. Treat it as a separate channel strategy, not just a cheaper Amazon clone.

• Is TikTok Shop worth it?

  TikTok Shop can work well for visual, impulse-buy products that benefit from creator content and short-form video demos. But its fee stack, logistics rules, and promotional mechanics can change quickly, so use this page as a screening worksheet and verify the exact seller costs inside TikTok Shop before you price inventory.

• How many channels should I sell on?

  Start with 1–2 channels, master them, then expand. Most successful sellers operate on 3–5 channels. Each additional channel increases revenue but also complexity in inventory management, customer service, and listing optimization. Use multi-channel management tools (ChannelAdvisor, Sellbrite) at 3+ channels.
