How is this calculated?

This tool does one simple calculation: the number of stock-related cancelled or refunded orders you enter multiplied by their average order value.

Monthly affected order value = affected orders × average affected order value.
Annual affected order value = monthly affected order value × 12.
Share of orders = affected orders ÷ total monthly orders.

It does not assign an assumed refund rate, support cost, repeat-purchase penalty, advertising equivalent, or predicted oversell rate. Use your own accounting data if you want to convert affected order value into contribution-margin loss or total operational cost.
