DECISION GUIDE
How to use this result in a real decision.
What remains from one marketplace sale after the settlement's major deductions? Model revenue and each deduction separately so the estimate can be reconciled with an actual order or payout statement.
WORKED EXAMPLE
$65 marketplace sale
Inputs
$22 product cost, 15% marketplace fee, 3% payment fee, $8 ads, $3 fulfillment, $6 shipping and a 4% returns reserve.
Calculated result
Fees are $11.70 and the returns reserve is $2.60. Estimated profit is $11.70 per unit, or an 18% margin, before overhead and tax.
Decision meaning
Advertising could rise by at most $11.70 before the modeled order reaches break-even, but operating overhead requires a lower practical ceiling.
Check before acting
Use the net item price after seller-funded discounts.
Match marketplace and payment fees to the exact category, plan and country.
Compare the estimate with recent settlement statements and refund history.
Not included automatically
Storage, subscription, listing and long-term inventory fees
Tax remittance, currency conversion and financing

How to use it
A better estimate in three steps.
01
Enter customer revenue, including shipping charged.
02
Add every cost paid by the seller for one unit.
03
Scale the result by units to estimate order or monthly profit.
If collected tax is not your revenue, exclude it from selling price. For tax-specific accounting, use your marketplace statement and professional guidance.
Where do coupons belong?
Use the actual selling price after seller-funded discounts.
What is returns reserve?
It is a planning allowance for expected refunds, lost margin, and unrecoverable return-related costs.
