Example
Your B2B SaaS campaign spent $2,400 on Meta ads last month and generated 80 leads.
| Metric | Value | Calculation |
|---|
| Meta Spend | $2,400 | Total spent on Meta |
| Meta Leads | 80 | Form submissions attributed to Meta |
| Meta Cost per Lead | $30.00 | $2,400 ÷ 80 |
How It Works
Cost per Lead divides your total Meta ad spend by the number of lead events tracked via the Meta Pixel or Conversions API. A lead event fires when someone submits a form, signs up for a newsletter, or completes another lead capture action on your site. Lower CPL indicates more efficient lead generation.
