What this calculator does
The ROAS Calculator gives agencies and media buyers the fastest way to compute return on ad spend for any campaign or channel. Enter spend and attributed revenue and the tool returns ROAS as a multiple, revenue per dollar, and the extra revenue required to reach a target ROAS. Use it mid-flight to decide whether a campaign deserves more budget, in client reviews to translate spend into return, or in proposals to set realistic performance targets. Because ROAS is the metric clients quote back to agencies more than any other, having a clean, repeatable calculation - identical across Google Ads, Meta Ads, LinkedIn and TikTok - keeps conversations grounded in the same math. Pair it with break-even analysis to know the minimum ROAS your margins can tolerate.
How to use this calculator
- 1
Enter total ad spend and the revenue attributed to that spend for the same period.
- 2
Set your target ROAS to see the revenue gap between current and goal.
- 3
Compare ROAS across channels to guide where the next budget dollar goes.
Why this matters for agencies
ROAS is the single number most clients use to judge paid media. Calculating it consistently across channels prevents cherry-picking and makes budget conversations objective. Knowing the gap to a target ROAS turns a vague "do better" into a concrete revenue goal.
Frequently asked questions
What is a good ROAS?
It depends on margins. E-commerce with healthy margins often targets 3x to 4x; low-margin retail may need 6x or more, while high-LTV SaaS or lead-gen can be profitable below 3x. Calculate your break-even ROAS from gross margin first, then set targets above it.
How is ROAS calculated?
ROAS = attributed revenue divided by ad spend. A campaign that generates $38,000 from $10,000 of spend has a 3.8x ROAS.
Is ROAS the same as ROI?
No. ROAS ignores costs beyond ad spend. ROI subtracts all costs, including product costs and agency fees, so ROI is always lower than ROAS for the same campaign.
Should ROAS be measured per channel or blended?
Both. Per-channel ROAS guides budget allocation; blended ROAS across all paid channels shows the true return of the whole program and catches attribution overlap between platforms.
