Amazon Settlement Decoder
Amazon's take rate — referral plus FBA fulfilment fees as a share of principal sales this month, from the settlement flat file — with everything else Amazon charged beside it.
What the file tells you
The settlement flat file has forty columns and the truth. Paste it and the sheet classifies every line — principal, referral, FBA, shipping chargebacks, promotions, refunds and the fees Amazon keeps on them, storage, advertising, subscription — into one take rate and one net per unit for your pricing.
FBA sellers who know their revenue and have never seen their net per unit.
