Marketplace Fee Comparator

What this marketplace fee comparator is for

Choosing where to sell is rarely about one headline percentage. The same product can look attractive on one channel and unprofitable on another once referral fees, payment processing, listing fees, fulfillment, and plan overhead are included. This page puts one price, one product cost, and one shipping cost through simplified models for several major channels so you can see relative estimated net side by side.

It is a planning hub, not a substitute for each platform’s fee schedule or Seller Central / shop bill. After you spot a promising channel, open the dedicated calculator for that marketplace and confirm current policy pages before you buy inventory.

How to read the table

• Est. fees — Simplified platform-side fees under the active region preset.
• Est. net — Item price minus those fees, minus product cost, minus shipping you pay.
• ★ row — Highest estimated net under this model only. It is not a ranking of “best marketplace overall.”
• Open → — Deeper tool for that channel (inputs, Offsite Ads, FBA tiers, etc.).

What each row approximates

• Etsy — Listing-style amount plus transaction and processing-style components (region-adjusted). Does not fully model every Offsite Ads case; use the Etsy fee calculator for Offsite and shipping charged vs cost.
• Amazon — Simplified referral percentage plus the FBA fulfillment amount you enter. Not a full size-tier warehouse model; use the Amazon FBA calculator and Fee Preview.
• Walmart — Referral-only style estimate. Add WFS or your own fulfillment outside this row when relevant.
• eBay — Category-agnostic final-value style percentage plus a small per-order component. Confirm category rates on eBay; use the eBay fee calculator.
• Shopify est. — Payments-style percentage and fixed fee plus a rough monthly plan cost divided across assumed orders. Real Shopify cost depends on plan, apps, and payment stack.
• TikTok Shop — Simplified take-rate style row. Creator commissions and fulfillment programs vary; open the TikTok tool when available.
• Poshmark — Flat fee under a low price threshold, otherwise a percentage-style model.

Region presets

US, UK, Canada, Australia, and EU-style options adjust simplified coefficients. They are not official multi-country rate cards. Tax display, VAT, and local category rules can change real outcomes. Always confirm on the marketplace and country where you actually list.

Worked planning example

Suppose item price $40, product cost $12, shipping you pay $0, and Amazon FBA $5. Under a US-style preset, channels with lower modeled platform fees may show higher net — until you add realistic FBA, Offsite Ads, or Shopify app costs. Change FBA to $8 or add shipping you pay, and the ★ row can flip. That sensitivity is the point of the comparator: stress-test assumptions before you commit.

Recommended workflow

1. Enter realistic price, COGS, and shipping you pay.
2. Set Amazon FBA from Fee Preview when comparing FBA-heavy products.
3. Note the top two channels by estimated net.
4. Open each channel’s dedicated calculator for finer inputs.
5. Confirm live fees on the platform help pages for your category and country.
6. Only then decide listing priority or inventory allocation.

What this tool does not decide

• Where you will rank or convert
• Brand fit, return rates, or customer service load
• Advertising cost of sales
• Legal, tax, or accounting treatment

Fees are one input. Demand and operations still matter.
