TikTok states that FBT fulfillment fees include picking, packing, packaging and last-mile shipping and are charged per unit. The fee tier depends on chargeable weight, while multi-unit orders can use different per-unit rates.
From May 1, 2026, units at or below 2 lb and 332 cubic inches use actual weight. If either limit is exceeded, this calculator uses the greater of actual weight and dimensional weight (L × W × H ÷ 166), matching TikTok's published rule.
TikTok has changed several FBT tiers during 2026, including multi-unit rates and heavy/bulky support. Rather than silently applying a stale fee, TokProfitCalc calculates the chargeable weight and keeps the fulfillment fee editable so you can use the current amount for your exact tier.
The comparison uses the same product price, COGS, referral fee and creator commission, changing only the fulfillment cost. This makes the per-order cost difference easy to see. It does not value operational benefits such as FBT's logistics metric protection or delivery badge.
