Top-of-funnel scope
Include the total leads generated for the same period and use a consistent definition of customer acquired. This shows how much of the broad lead pool becomes customers.
Lead versus sales conversion
Lead conversion covers the full generated-lead pool. Sales conversion begins with qualified sales opportunities and isolates the later pipeline stage.
Worked example
12 customers from 200 generated leads produces a 6% lead conversion rate.
Frequently asked questions
Practical questions people ask about this tool
Can customers exceed leads?
No. The calculator flags that input because customers acquired cannot exceed total leads in this simple count model.
Does this include unqualified leads?
Yes. Lead conversion starts with all leads generated, including unqualified leads.
How is this different from sales conversion?
Sales conversion uses qualified opportunities; lead conversion uses the total lead pool.
