What did the unit actually contribute?
True profit is contribution after discounts, COGS, marketplace fees, payment fees, shipping, refund impact and fulfillment — not the number in your sales dashboard.
Contribution profit$35.00
Sale$120.00
All costs$85.00
Formula
contribution = sale − discount − cogs − marketplace_fee − payment_fee − shipping − refund_impact − fulfillment
Example
A $120 boot with $5 discount, $43 COGS, $18 marketplace fee, $4 payment fee, $9 shipping, $6 refund impact contributes $35 — if those inputs are exact.
