Frequently asked questions

Everything you need to know about fulfillment fee calculations.

What is Inventory Hero's fulfillment fee calculator?
Inventory Hero's free fulfillment fee calculator lets Amazon and TikTok Shop sellers instantly compare FBA and Fulfilled by TikTok (FBT) costs side by side. Enter your product's dimensions, weight, and selling price, and Inventory Hero shows the exact fulfillment fee, cumulative storage cost, and grand total for both platforms.
How are Amazon FBA fulfillment fees calculated in 2026?
Amazon FBA fulfillment fees depend on two things: size tier and shipping weight. Starting January 15, 2026, Amazon introduced price-banded rates: items under $10, $10 to $50, and over $50 each have different fee schedules. See Amazon's official size tier definitions and fulfillment fee schedule for full details.
How does TikTok Shop fulfillment pricing work?
TikTok Shop (Fulfilled by TikTok) uses a base-plus-weight model. The 2026 base fee is $3.58 for a single item up to 1 lb, plus $1.70 for each additional pound. Multi-unit orders get per-unit discounts. See TikTok's official Fulfilled by TikTok fee page for the full rate card.
How does dimensional weight affect my fees?
Dimensional weight estimates how much space a package occupies. The formula is L × W × H (inches) divided by a platform-specific divisor. Amazon FBA uses 139; TikTok Shop uses 166. Because TikTok's divisor is larger, the same box produces a lower dimensional weight on TikTok, which can mean lower fees for lightweight, bulky products.
Is this calculator accurate and up to date?
Yes. Inventory Hero's calculator is built directly from the official Amazon Seller Central fee schedule and TikTok Shop's Fulfilled by TikTok rate card. All calculation logic is covered by automated tests to ensure accuracy.
