Frequently Asked Questions
How do you calculate cost per lead?
Cost per lead = total marketing spend ÷ number of leads generated. If you spend $10,000 and generate 250 leads, your CPL is $40.
What is a good cost per lead?
It depends heavily on industry and deal size — a B2B SaaS lead worth thousands can justify a $100+ CPL, while a low-ticket consumer lead might need to be under $10. Judge CPL against the revenue each lead can produce, not in isolation.
What is the difference between cost per lead and cost per acquisition?
CPL is the cost to generate a lead (an interested prospect). CPA (or cost per customer) is the cost to convert one into a paying customer — always higher than CPL because not every lead closes.
Why is cost per lead important?
It tells you whether your marketing is economically viable. Combined with close rate and deal value, CPL reveals which channels actually produce profitable customers versus cheap-but-low-quality leads.
How do I lower my cost per lead?
Improve targeting, raise landing-page conversion rates, shift budget to higher-performing channels, and strengthen organic/PR sources that generate leads without per-click cost. Better-qualified leads also raise close rates, lowering true cost per customer.
