Frequently Asked Questions

What is ROAS on Amazon?

ROAS (Return on Ad Spend) = Revenue ÷ Ad Spend. A ROAS of 4x means you earn $4 for every $1 spent on ads. It is the inverse of ACoS.

What is a good ROAS for Amazon ads?

Good ROAS depends on your margins. Generally: 3x ROAS = break-even for many sellers, 4-5x ROAS = profitable, 7x+ ROAS = excellent. Our calculator helps determine your target.

How do I improve my Amazon ROAS?

Improve ROAS by: 1) Better keyword targeting, 2) Improved listing conversion, 3) Optimizing bids, 4) A/B testing ad copy, 5) Using negative keywords, 6) Focusing on high-converting products.

What is the relationship between ROAS and ACoS?

ROAS = 1 / ACoS (as decimals). So 25% ACoS = 4x ROAS. 20% ACoS = 5x ROAS. 10% ACoS = 10x ROAS. They measure the same thing differently.
