Net margin shows whether the product can survive fee increases, PPC volatility, discounts, and returns. Very low margins are risky even when sales volume looks strong.
Use exact SKU-level cost data when available. Account-level averages can hide weak-margin products.
A $65 product with $24 cost, $12 Amazon fees, and $8 ads plus shipping has $21 profit and 32.3% net margin.
A strong Amazon net margin is often 20% to 30% or higher after fees, fulfillment, advertising, shipping, and expected returns.
Subtract product cost, Amazon fees, ads, shipping, storage, and return costs from selling price, then divide profit by selling price.
Improve sourcing, raise perceived value, reduce PPC waste, optimize packaging, lower returns, and avoid excessive discounts.
Common margin reducers include referral fees, FBA fulfillment fees, PPC spend, shipping, storage, returns, and coupon discounts.
A 30% net margin is realistic for differentiated products with controlled ad costs and strong sourcing, but difficult in highly competitive commodity categories.
