BEHIND THE RESULT

See what stays after the order is fulfilled

Revenue is the item price plus any shipping paid by the buyer. Landed supplier cost combines the selected product, supplier freight and applicable purchase tax you enter. The calculator then subtracts marketplace charges, advertising assumptions and other fulfilment expense. Keep the same currency throughout, and avoid entering the same freight or tax twice. A supplier parent-page starting price is not the cost of a selected variation.

Profit bridgeRevenue − landed supplier cost − eBay fees − ads − fulfilment expense = estimated net profit.

Margin and ROI answer different questions. Margin compares net profit with buyer revenue; ROI compares it with landed supplier cost. A strong ROI can coexist with a modest margin if the denominator is small. In target-profit mode, the tool searches for the lowest cent of item price that meets your chosen net amount under the selected fee rules. That price is a calculation, not proof that a buyer will accept it. Revisit the estimate when fees, destination shipping or supplier cost changes.

Worked example

Consider a hypothetical $40 item with $5 buyer-paid shipping: revenue is $45. Suppose the exact product costs $18, supplier freight is $3, seller postage is $5, marketplace charges are $5 and an attributed ad charge is $2. Estimated net profit is $12. Margin is $12 ÷ $45, or 26.7%; ROI on the $21 landed supplier cost is 57.1%. Neither percentage includes a cost you leave blank. If purchase tax is already in the $18 product figure, adding it again would make the estimate too low; if the supplier changes its freight by destination, the same listing price can produce a different result.

Before you act

If the outcome changes sharply when you add postage, ads or purchase tax, keep those assumptions visible in the saved comparison. Check an actual order later to see which estimate was too low.

THREE-STEP CHECK

Use the result with a clear source trail

  1. 01

    Enter the actual listing price and one consistent currency.

  2. 02

    Add the exact supplier variant cost, destination shipping, applicable tax, fees and optional advertising assumptions.

  3. 03

    Read profit, margin and ROI separately; compare the estimate with actual order statements later.

Questions sellers ask

Is margin the same as ROI?

No. Margin divides profit by revenue; ROI divides profit by the chosen investment denominator. This tool uses landed supplier cost.

Does the tool verify my fee rate?

No. Confirm your marketplace, category and seller terms before relying on the result.
