One product, four fee stacks, no agenda
Multi-channel sellers ask a deceptively simple question — where does this product make more money? — and almost nowhere answers it honestly, because every comparison online is published by a platform, a fulfilment service or a course. This page runs one product through four complete fee stacks at once: Amazon FBA with its full 2026 stack, Amazon FBM with your own label, TikTok Shop self-shipped, and TikTok FBT — same price, same product costs, same ad load, same unsellable-return share, so the ranking you get is the channels' arithmetic and nothing else.
The structural difference in one line: Amazon charges more platform-side (referral plus a tiered fulfillment machine) and nothing for creators; TikTok charges a flat referral but expects an affiliate commission on the orders creators drive. Which structure wins depends on your commission rate and your label costs — the two inputs sellers guess at most.
Worked example
At the defaults — the $29.99 gadget from the FBA calculator, a 12% affiliate commission on 60% of TikTok orders — TikTok self-ship leads at about $8.48, FBT follows at $8.27, Amazon FBA keeps $6.85 and FBM trails at $5.79 on a $6.25 label. Push the affiliate commission past roughly 21% and FBA retakes the lead; that sensitivity — two inputs deciding the winner — is the real lesson of the table.
How to use this calculator
- Enter the product once — every channel inherits the same economics.
- Paste your real FBT rate and your real FBM label cost; placeholders flatter whoever they came from.
- Set the affiliate share honestly: a product that only moves through creators is a different business from one with organic demand.
- Use the ranking to decide where to launch and where to expand — then run the winning channel's own deep calculator on this page for pricing.
