Worked example

1,000 orders with a 10% return rate and an $18 net loss per return implies 100 returns and $1,800 of modeled loss, or $1.80 spread across every original order.

What to do with the result

Adding the per-order return allowance to your normal product economics prevents return-heavy products from looking better than they are.
