Direct answer: A lead funnel calculator measures the conversion rate between visits, leads, qualified leads and sales. Use the same acquisition cohort and written stage definitions so delayed sales and duplicate leads do not distort the rates.
Use funnel rates responsibly
Compare the same cohort and definitions. A lead generated today may close months later. Track response time and rejection reasons alongside conversion rates.
Funnel formulas
- Visit-to-lead rate = leads ÷ visits.
- Lead-to-qualified rate = qualified leads ÷ leads.
- Qualified-to-sale rate = sales ÷ qualified leads.
Find the real constraint
A weak visit-to-lead rate can indicate poor relevance or page friction. Weak qualification often points to targeting, offer or validation. Weak sales conversion can reflect response time, follow-up, price or product fit.
Frequently asked questions
What is a lead funnel?
It is the measured progression from audience or visits through enquiries, qualification, opportunities and sales.
How do I calculate conversion rate?
Divide the later-stage count by the earlier-stage count and multiply by 100.
Why should cohorts be used?
Leads generated in one period may close later; cohorts keep acquisition and outcomes connected.
What is a qualified lead?
It is a lead meeting agreed evidence for fit, intent and a meaningful next step.
Can conversion rates be compared across industries?
Only carefully. Definitions, sales cycles, channels and offers differ.
