How to use it

  1. Enter spend and any available campaign totals.
  2. Select Calculate metrics. Missing inputs are fine.
  3. Review the available results and compare them with your own historical performance.

Method and formula

CPM = spend ÷ impressions × 1,000; CPC = spend ÷ clicks; CTR = clicks ÷ impressions × 100; CVR = conversions ÷ clicks × 100; CPA = spend ÷ conversions; ROAS = revenue ÷ spend; AOV = revenue ÷ conversions.

Worked example

With $1,000 spend, 100,000 impressions, 2,000 clicks, 80 conversions and $4,000 revenue: CPM is $10, CPC is $0.50, CTR is 2%, CVR is 4%, CPA is $12.50, ROAS is 4× and AOV is $50.

Limitations

  • A high ROAS is not automatically profitable; compare it with your break-even ROAS.
  • Attribution windows, refunds, taxes and platform reporting differences are not included.
  • Industry benchmarks vary widely. Your own comparable historical data is usually the better benchmark.
