ROAS Benchmarks
Amazon FBA ROAS Benchmarks
What a profitable ROAS actually looks like for Amazon FBA sellers, based on typical margins and cost structures.
Typical Gross Margin20% – 35% after marketplace fees
Break-Even ROAS2.8x – 5.0x
Target ROAS Range3.5x – 6.0x
Why This Number
FBA sellers face compounding costs — manufacturing, freight, Amazon storage fees, fulfillment fees, and referral fees — requiring a higher ROAS to find profit compared to standalone ecommerce.
Common Mistake
Evaluating ad ROAS in isolation and ignoring its impact on organic ranking — ad sales improve organic search placement on Amazon, so pausing ads with a mediocre ROAS can cause profitable organic sales to collapse as product ranking drops.
