CPL = marketing spend ÷ leads. A low CPL only helps if those leads actually convert.
What is CPL?
Cost per lead (CPL) is how much you spend, on average, to generate one lead. It's the top-of-funnel efficiency metric that feeds into CAC once leads convert.
CPL = marketing spend ÷ leads generated
How to read your result
- CPL measures leads; CPA/CAC measure customers — don't conflate them.
- A low CPL is only good if those leads actually convert.
- Compare CPL by channel to shift budget to efficient sources.
- Track CPL alongside lead-to-customer conversion rate.
Frequently asked questions
What's the difference between CPL and CAC?
CPL is the cost to generate a lead; CAC is the fully-loaded cost to win a paying customer. Many leads become customers, so CAC is always higher than CPL.
