How this tool works.

Referral fee = fee base × referral rate / 100. Total cost = product + referral fee + fulfillment + inbound shipping + ads + other costs. Profit = selling price − total cost. ROI = profit / total cost × 100.

A worked example

Put it into practice.

A 40 sale with a 6 referral fee and 23 in other entered costs has total costs of 29, profit of 11, margin of 27.50% and ROI of 37.93%.

Examples use illustrative amounts in a single currency. Results are estimates, not guaranteed outcomes or marketplace quotations.
