TikTok Shop vs Amazon FBA: Fee Comparison for Sellers

SellerVault Team·2025-02-28·4 min read

Many e-commerce sellers are debating whether to expand to TikTok Shop or double down on Amazon FBA. The fee structures are surprisingly different. Let's compare them head-to-head.

Fee Structure Overview

TikTok Shop Fees (US)

Referral fee: 6% unified (includes payment processing — no separate transaction fee)
Affiliate commission: 5-20% (seller-set, optional but common)
FBT fulfillment: $3-5 per order (varies by size/weight)

Note: TikTok rolled the transaction fee into a single unified referral rate. Older guides mentioning a separate "2.9% + $0.30 transaction fee" are outdated. UK and EU sellers pay a higher 9% referral rate.

Amazon FBA Fees

Referral fee: 8-15% (varies by category, most categories are 15%)
FBA fulfillment: $3.22-$5.40+ per unit (varies by size/weight)
Storage fees: $0.87-$2.40 per cubic foot per month
No separate transaction fee (included in referral fee)

Side-by-Side: $30 Product Comparison

Let's compare a $30 product in the "Health & Beauty" category:

TikTok Shop (with 15% affiliate, FBT)

Referral fee: $1.80 (6%)
Affiliate fee: $4.50 (15%)
FBT fulfillment: $3.58
Total fees: $9.88 (32.9% of revenue)

Amazon FBA

Referral fee: $4.50 (15% for beauty)
FBA fulfillment: $3.86 (standard size)
Storage fee: ~$0.15/month (amortized)
Total fees: $8.51 (28.4% of revenue)

Winner: Amazon FBA by $1.37 per order — but the gap is much smaller than it used to be, thanks to TikTok's unified 6% referral rate.

But Wait — The Affiliate Factor

The biggest variable is TikTok's affiliate commission. Without affiliates:

TikTok Shop (no affiliate, FBT)

Referral fee: $1.80 (6%)
FBT fulfillment: $3.58
Total fees: $5.38 (17.9% of revenue)

Without affiliate commissions, TikTok Shop is significantly cheaper than Amazon FBA — by over $3 per order. The question becomes: can you drive traffic without affiliates?

Where TikTok Shop Wins

Lower base fees — 6% unified referral vs Amazon's 15% in most categories. That's a 9 percentage point difference.
No storage fees — You don't pay monthly warehouse costs
Lower advertising costs — Organic discovery through creator content can replace paid ads
Faster launch — Less competition for visibility on new products
No separate transaction fee — Everything is included in the 6% referral

Where Amazon FBA Wins

No affiliate costs — You pay for PPC ads instead, but you control the spend
Higher conversion rates — Buyers on Amazon have stronger purchase intent
Prime badge — Builds instant trust and drives conversion
Predictable fees — No affiliate commission surprises

The Real Comparison: Total Cost of Customer Acquisition

The fee comparison alone doesn't tell the whole story. You need to factor in:

TikTok: Fees + affiliate commissions (or content creation costs)
Amazon: Fees + PPC advertising costs (typically 15-30% of revenue for competitive niches)

When you add Amazon PPC costs, the total cost structure often comes out similar to TikTok with affiliates. And TikTok's lower base fees mean you keep more on organic sales.

UK & EU Sellers: The Calculus Is Different

If you sell in the UK or EU, TikTok's referral fee jumps to 9% (still no separate transaction fee). That narrows the gap with Amazon:

TikTok Shop UK (£30, with 15% affiliate, FBT)

Referral fee: £2.70 (9%)
Affiliate fee: £4.50 (15%)
FBT fulfillment: £3.58
Total fees: £10.78 (35.9% of revenue)

The higher referral rate makes TikTok UK/EU more expensive, but Amazon UK also charges 15% referral in most categories — so TikTok is still competitive when you factor in Amazon's storage and FBA fees.

Our Recommendation

Don't choose one or the other — diversify. The smartest sellers we see are on both platforms, using each for its strengths:

TikTok Shop for products that go viral, impulse buys, and reaching younger demographics
Amazon FBA for steady baseline revenue, products with strong search demand, and established brands

The key is tracking your real profit on each platform separately. What's profitable on Amazon might not be profitable on TikTok, and vice versa. Know your numbers per platform, per product.
