Frequently Asked Questions — Amazon ROAS & ACoS Conversion
Key facts regarding ROAS multipliers, revenue per dollar, and conversion benchmarks
What is Amazon ROAS (Return on Ad Spend)?▼
ROAS (Return on Ad Spend) measures how much ad revenue you generate for every $1 spent on Amazon PPC ads. It is calculated as Total Ad Revenue ÷ Total Ad Spend.
How do I convert ACoS to ROAS and vice versa?▼
ACoS and ROAS are inverse formulas: ROAS = 1 ÷ (ACoS ÷ 100). ACoS % = (1 ÷ ROAS) × 100. For example, a 25% ACoS equals a 4.0× ROAS, and a 20% ACoS equals a 5.0× ROAS.
What is a good ROAS on Amazon?▼
A good ROAS depends on your profit margin. If your pre-ad profit margin is 25%, a ROAS of 4.0× is break-even. Anything above 4.0× yields net profit.
What does 'Revenue per $1 Spent' mean?▼
Revenue per $1 spent is identical to your ROAS multiplier. A ROAS of 3.5× means that for every $1 you spend on PPC, you generate $3.50 in total ad sales.
Why should I track both ACoS and ROAS?▼
ACoS expresses ad efficiency as a percentage (useful for margin comparison), while ROAS expresses efficiency as a multiplier (useful for return on investment comparisons across ad channels).
