How it works
Net payout is customer payment after entered marketplace and payment fees. Product and fulfillment costs must also be deducted to estimate profit.
The formula
Keep currency, units and time periods consistent. Percentage inputs use percentage points (enter 5 for 5%). Results are rounded only for display; tiny nonzero values may use scientific notation. Undefined ratios are shown as unavailable.
Item price: $100.00; Shipping charged: $5.00; Customer payment: $105.00; Marketplace fee 15%: $15.75; Payment fee 2.9% + $0.30: $3.35; Listing + other: $1.20; Total fees: $20.295 (about $20.30); Net payout: $84.705 (about $84.71); Fee burden: 19.33%.
Calculation method
Percentage fees apply to the selected base: item price alone or item plus shipping charged. Fixed payment, listing and other fees are added separately.
Interpretation
The largest fee component highlights where entered costs accumulate. A break-even price holds shipping revenue and fee rates constant while solving for the item price.
Limitations
Enter current applicable fee rules yourself. This general calculator does not include platform-specific tiers, tax withholding, refunds or currency conversion.

Why does the fee base matter?
