How this calculation works
Simple customer contribution estimate after an assumed refunded-revenue rate.
Worked starting inputs
Example inputs: Avg Spend = 100.0, Orders Per Customer = 2.0, Refund Rate Pct = 8.0, Gross Margin Pct = 40.0. Expected result: Expected retained gross contribution: $73.60. These are illustrative numbers, not market rates. Change a value to compare scenarios; download the result if useful.
Assumptions and limitations
Manual estimates depend on your data and assumptions.
Every result depends on the entered values. The tool does not fetch marketplace fees, infer current exchange rates or verify supplier policies. It is informational, not tax or financial advice.
