TikTok Shop fees in 2026 — the full breakdown
TikTok Shop layers a referral fee by market, a fulfillment choice, and return costs that depend on your performance score. Here is the 2026 picture.
Fee snapshot
| Fee | 2026 rate | Notes |
|---|---|---|
| Referral fee | 6% US / 9% UK / 6%+2% EU | new US sellers often start at 3% for 30 days |
| FBT fulfillment | from $3.58 | 60 days free storage, then monthly storage |
| Refund admin fee | ~20% of referral, capped ~$5 | kept by TikTok on each return |
| Return shipping share | 20% at SPS 4+ | your share rises as Shop Performance Score drops |
| Ads | charged on gross sales | returns do not refund ad spend |
What the numbers mean for a seller
The referral rate is set by market, and the 30-day new-seller window means the effective rate changes if you price during it. FBT's flat fee looks high until you add the conversion lift it brings. Returns are the hidden line — the admin fee plus your SPS-based shipping share can turn a profitable SKU negative, which is why the refund cost calculator exists.
Where each number gets calculated
- Affiliate commission — max creator rate that keeps your margin
- FBT vs self-fulfillment — monthly net on both routes
- Break-even ROAS — what ads must return post-returns
What TikTok Shop sellers need to track
Free calculators that surface each real cost of selling on TikTok Shop before it eats your margin.
Creator commissions
Affiliate commissions are seller-set and locked for 30 days once published. Find the break-even commission before you set a rate.
Fulfillment model
FBT (Fulfilled by TikTok) costs from $3.58/unit with 60 days free storage, but lifts conversion; self-fulfillment on TikTok Shipping keeps more per unit. Compare the two models on monthly net profit.
Returns & ads
TikTok keeps a refund administration fee and charges ads on gross sales that returns do not refund. Budget the real return cost and find your break-even ROAS before scaling.
EU compliance
Selling into the EU means EPR packaging registration and GPSR labeling. Estimate packaging weight and run the GPSR checklist.
