Using the result

Keep the funnel stages explicit

Cost per lead describes the price of generating a lead; CPA describes the price of the completed action entered as a conversion. Those numbers answer different questions when leads still require qualification or sales follow-up.

Compare campaigns only when their conversion definitions, date ranges, currencies, attribution windows, and lead-quality standards match.
