Net marketplace proceeds = Selling price + buyer-paid shipping − percentage fees − fixed fees − fulfillment and optional service charges
Use consistent periods and units throughout the calculation. When rates are entered as percentages, convert them to decimals for arithmetic unless the interface performs that conversion automatically.
What the result means
It converts the entered assumptions into a consistent estimate of marketplace fee. The result is most useful for comparison and planning when every input covers the same scope.
Verify current fee schedules and distinguish fees collected from the seller from taxes collected from the buyer. Recalculate when the underlying inputs change, and use source records rather than memory for material decisions.
A $75 sale with $9 total percentage fees, $0.40 fixed fees, and $8 fulfillment leaves $57.60 before product cost.
The example illustrates the mechanics only. Replace every example value with data that reflects the user’s actual period, account, policy, or scenario.
