Free Funnel Revenue calculator with clear step-by-step results.
Multiplies visitors through three sequential conversion stages, which is why funnel maths is so unforgiving - the end-to-end rate is the product of the stages, so a 6%, 35% and 22% funnel converts under half a percent of visitors. Improving the weakest stage moves revenue more than adding traffic.
Stage progression
Leads = visitors x lead rate; qualified = leads x qualified rate; won = qualified x close rate
End-to-end conversion
Overall % = lead rate x qualified rate x close rate x 100
Usually the stage with the lowest absolute rate that you can influence. A relative improvement anywhere multiplies through, so a 20% lift in the worst stage is worth the same as a 20% lift in the best.
No. It treats the funnel as instantaneous. With a long cycle, revenue lands months after the traffic, so cohort the visitors by entry period before comparing to booked revenue.
