ROAS Calculator FAQ
What does 4x ROAS mean?
A 4x ROAS means every $1 of ad spend generates $4 in attributed revenue.
Is ROAS the same as ROI?
No. ROAS looks at revenue versus ad spend only, while ROI typically accounts for broader costs and profit.
Why show ROAS as both a ratio and percentage?
Different teams prefer different formats. Many marketers use the ratio, while reports may use a percentage.
Can ad spend be zero?
No. A zero spend value makes the ratio undefined, so the calculator requires a positive spend amount.
