What this calculator measures
Measures the marketing cost incurred to acquire a single qualified lead.
Common use cases
Use this model when the inputs describe the same decision, period and customer or product scope.
- Compare the spend required to generate leads across campaigns, channels or landing pages.
- Check whether a lower lead cost is offset by weaker qualification or conversion to customers.
- Combine CPL with lead-to-customer rate and customer value before reallocating budget.
Formula
Cost per lead = Campaign cost ÷ Qualified leads
Define both campaign cost and qualified lead consistently.
Worked example
$5,000 marketing spend divided by 100 leads equals $50 per lead.
How to interpret the result
Helps evaluate marketing channel efficiency and ROI.
Assumptions and limitations
- Leads meet the established qualification criteria.
