| Metric | Formula | Default example |
|---|---|---|
| CPC | Spend ÷ Clicks | $500 ÷ 1,000 = $0.50 |
| CTR | (Clicks ÷ Impressions) × 100 | (1,000 ÷ 50,000) × 100 = 2% |
| CPM | (Spend ÷ Impressions) × 1,000 | ($500 ÷ 50,000) × 1,000 = $10 |
| CPA | Spend ÷ Conversions | $500 ÷ 25 = $20 |
| ROI % | (Revenue − Spend) ÷ Spend × 100 | ($2,500 − $500) ÷ $500 = 400% |
| ROAS | Revenue ÷ Spend | $2,500 ÷ $500 = 5:1 |
