Use one matched funnel and period: acquisition spend, leads generated from that scope, and customers acquired from those leads.

Optional for CPL-only. Keep this to the same lead cohort.

Koala's Calculated Result
CPL = spend ÷ leads. CPA = spend ÷ acquired customers.

Add acquisition spend and at least one lead. CPA also needs an acquired-customer count.

Frequently asked questions

What is CPL vs CPA?

CPL is acquisition spend divided by leads on a matched scope and period. CPA is acquisition spend divided by completed acquisitions on its matched scope and period. Their relationship depends on funnel definitions and lead-to-customer conversion; do not assume one fixed multiple between them.

CPL & CPA

Should I track both?

Yes. CPL tells you how efficiently you produce a top-of-funnel contact; CPA tells you how efficiently you produce a paying customer. CPL is useful for diagnosing creative and audience; CPA is useful for diagnosing unit economics overall.

CPL & CPA

Why include a lead-to-customer rate?

A lead is meaningless until it converts. Enter the % of leads that actually convert to a sale and the calc reveals the implied CPA — without that input, the calc is only half-true.

CPL & CPA

When is CPL too high?

When CPL × lead-to-customer rate > LTV ÷ margin. Above that threshold every additional lead costs more than the per-customer profit it brings in. Use the figure as the early warning before the funnel collapses.
