How the threshold is calculated
The model treats merchandise cost as a percentage of subtotal, then solves directly for the subtotal that covers shipping, processing, fixed costs, and target profit.
This estimates unit economics only. It does not predict whether customers will add items to reach a threshold. Confirm merchant-specific payment rates; sales tax is excluded.
