CPA vs CPL
A lead is a hand raised; an acquisition is a customer closed. CPL prices the first, CPA the second. The bridge is your lead-to-close rate: effective CPA = CPL ÷ close rate. Low close rates multiply brutally.

|---|---|---|
| 40% | 2.5× | $167 |
| 25% | 4× | $267 |
| 10% | 10× | $667 |
| 5% | 20× | $1,334 |
$66.69 ÷ close rate, rounded to the dollar. Your CPL and close rate replace the anchors.
Reporting
Which metric to report
- Channel teams optimize CPL: it is observable inside the ad account within days.
- The business runs on effective CPA: a $40 CPL closing at 5% is an $800 customer, worse than a $90 CPL closing at 20% ($450).
- Report the pair (CPL, close rate) per source. A cheap-lead channel with a weak close rate is how lead-gen budgets quietly die.
