Estimate your true FBA profit per unit after referral fees, fulfillment fees, and product costs. Referral fee defaults to 15% (most categories).
Two main fees: a referral fee (6-17% of sale price, 15% for most categories) and an FBA fulfillment fee based on size and weight (roughly $3.20-$6.50+ per standard unit). Storage fees are charged monthly per cubic foot and rise in Q4.
Many successful FBA sellers target 25-35% net margin before ad spend, or a rule of thumb of thirds: 1/3 product cost, 1/3 Amazon fees, 1/3 profit. After PPC, 15-20% net is common for healthy products.
Yes - enter your average ad spend per unit sold (total ad spend divided by units sold). TACoS above 15-20% usually signals a pricing or ranking problem.
