Multi-platform Commission Compare

In one line: See net profit on the same SKU across Amazon, Walmart, Newegg, eBay, and TikTok Shop side by side, and find where it sells best.

When to use

  • Deciding which marketplace to list a new SKU on first
  • Reallocating inventory toward the most profitable channel
  • Negotiating price by category when fee structures differ

Inputs

Field Notes
Selling price Planned listing price (kept constant across platforms for a fair comparison)
Category Drives the commission rate, which varies by platform and category
Unit cost Procurement plus shipping and packaging allocated per unit

Outputs

  • Net profit per platform — after each platform's category commission
  • Effective fee rate — commission as a share of selling price, per platform
  • Best-platform suggestion — the channel with the highest net profit for this SKU

Headline rate is not the full cost

A platform advertising an "8% commission" can still cost more than a 12% rival once fulfillment, payment processing, and ad requirements are added. Compare net profit, not the headline commission — a 2–4 point swing in effective fee can flip which channel wins.

FAQ

Why does the best platform change when I change the category?

Commission rates are set per category, not per platform overall. Electronics, apparel, and beauty can each carry different rates on the same marketplace, so the lowest-fee channel for one SKU may be the most expensive for another. Always compare at the category level.

Should I list on the single best platform only?

Not necessarily. Listing on the top one or two by net profit captures most of the upside while limiting operational overhead. Adding low-margin channels can still be worth it for volume, brand reach, or to diversify away from a single platform's policy risk.
