Most sellers now run both. Enter a price and your cost to see your blended net profit across both channels — plus break-even, the exact price to hit any margin, and how the same product does on each.

These default to typical US rates. Amazon's referral varies by category (8–17%) and FBA by size/weight — set your real ones for an exact number.

Creator commission applies only to affiliate-driven sales — set 0 if you don't use TikTok affiliates.

Common questions

Is the margin calculator free?⌄

Yes — the full calculator is free with no signup. Create a free account to see it automatically across all your real SKUs in Listora True Margin.

What is a break-even price?⌄

The price at which your net profit is exactly $0 — every fee is covered but you keep nothing. Sell below it and you lose money per unit.

What is a price floor?⌄

The lowest price that still leaves a healthy target margin (15% by default) after every fee, ad spend and returns. Pick 10/15/20/25% and it back-solves the price.

What fees does it include?⌄

Amazon: the 15% referral plus the FBA fulfillment fee. TikTok Shop: 6% referral, the $0.30 transaction fee, and creator/affiliate commission. Add ad spend and a return rate for the true number.

Can I compare Amazon vs TikTok?⌄

Yes — it shows the same product’s net profit, margin and price floor on both channels side by side, so you can see which one it wins on before setting a price.
