The Return Cost Math Formula
Mathematical formula2026–2027 specification
Real Loss per Return = Original FBA Fee + (Referral Fee × 0.20) + (COGS × Damage Rate)
Example: On a $30 item with $6 COGS and $4.50 FBA fee, a single return costs you approximately $5.40 to $8.20 in hard cash.
If your category return rate is 8%, every unit sold must carry a $0.43 to $0.65 hidden return reserve.
