Formulas used by the calculator

  • CTR: clicks ÷ impressions × 100.
  • CPC: ad spend ÷ clicks.
  • CPM: ad spend ÷ impressions × 1,000.
  • Conversion rate: conversions ÷ clicks × 100.
  • CPA: ad spend ÷ conversions.
  • ROAS: attributed revenue ÷ ad spend.

How to interpret the numbers together

No single metric tells the whole story. A strong click-through rate can coexist with a weak conversion rate, while an efficient CPA may still be unprofitable if order value or gross margin is too low. Compare metrics in the context of the campaign objective and economics.

Attribution affects ROAS

The revenue number should use a clearly defined attribution model and window. Platform-reported revenue, analytics revenue and finance-recognized revenue can differ, so document the source before comparing campaigns.

Zero denominators are shown as unavailable

If a required denominator is zero—for example, no clicks when calculating CPC—the calculator shows a dash instead of inventing a value.

Frequently asked questions

How is CTR calculated?
CTR equals clicks divided by impressions, multiplied by 100.
How is CPA calculated?
CPA equals advertising spend divided by the number of conversions.
Is ROAS the same as profit?
No. ROAS compares attributed revenue with ad spend and does not by itself include cost of goods, payroll, fees, overhead or other expenses.
Why does a metric show a dash?
The required denominator is zero, so a meaningful ratio cannot be calculated from the current inputs.
