CPM CPC CPA Converter
Convert between CPM, CPC, CPA, CTR, and conversion rate from campaign totals.
Bridge the common paid media metrics
Ad dashboards often show CPM, CPC, CPA, CTR, and conversion rate separately. Seeing them from the same campaign totals makes it easier to understand whether the issue is reach cost, click quality, or conversion efficiency.
The metrics interlock — CPC derives from CPM and click-through rate, and CPA from CPC and conversion rate — so entering campaign totals lets you fill in whichever figure you are missing.
Enter spend, impressions, clicks, and conversions. The converter calculates all five metrics from the same source numbers so you can compare campaigns or sanity-check a report.
