Quick answer
Ecommerce profit quick answer
Answer: Ecommerce profit per order is what remains after product cost, shipping, fulfillment, transaction fees, advertising, and other variable order costs are subtracted from order revenue.
Formula: Profit per order = order revenue − COGS − shipping − fulfillment − fees − advertising − other variable costs.
Example: An $80 order with $25 product cost, $6 shipping, $3 fulfillment, $2.40 in fees, and $18 ad cost leaves $25.60 in modeled order profit.
$80 sale − $25 product − $6 shipping − $3 fulfillment − 3% fees − $18 ads leaves about $25.60 profit per order.
What to do with the result
Model the order before scaling advertising. A product can look healthy on gross margin but become unprofitable after fulfillment and acquisition cost.
