What Is the Ad Metrics Calculator (CPM, CPC, CTR, CPA)?
The Ad Metrics Calculator turns the raw numbers from any ad campaign — impressions, clicks, spend, conversions and revenue — into every key metric at once: click-through rate (CTR), cost per click (CPC), cost per thousand impressions (CPM), conversion rate, cost per acquisition (CPA) and return on ad spend (ROAS). One screen instead of six formulas.
How It Works
Enter impressions, clicks, spend, conversions and revenue; all six metrics update live.
When to Use It
When reporting on paid campaigns, comparing channels or creatives, or sanity-checking a media plan's CPM and CPC assumptions.
