Worked example

Example inputs: 1,000 orders/mo, 10% return rate, $45 AOV, $6 return shipping, 5 min handling at $20/hr, 15% fees, 50% resellable

Returns cost $3,692/mo ($44,300/yr) across 100 returns — $36.92 per return, 8.2% of revenue.

  • Dominant cost driver: Largest component: Non-resellable inventory ($2250.00/mo)
  • Decision threshold: Cost per return $36.92; returns consume 8.2% of revenue.
  • Sensitivity: Margin status, largest return-cost component, cost per return, percentage of revenue consumed by returns, and sensitivity to return-rate change.
OptionResult
Non-resellable inventory$2250.00
Non-refunded fees$675.00
Return shipping$600.00
Labor$167.00

Example inputs — your own numbers will differ. A planning estimate, not a quote.

How this is calculated

Estimates monthly and annual return burden from return rate, labor time, non-resellable inventory loss, return shipping, and non-refunded fee percentage.

Formula: monthly_return_loss = returns_per_month × (labor_cost + inventory_loss + return_shipping + non_refunded_fees)

Fee basis: Fee schedule/source date: return-cost assumptions reviewed 2026-05-08; Amazon Returns Processing Fee is treated as explicit scope where user inputs it.
