The formula
Stage conversion = people at the next stage ÷ people at this stageOverall conversion = customers ÷ visitorsWorked example
From 5,000 visitors you get 250 leads (5%), 100 bookings (40% of leads) and 40 customers (40% of bookings). Overall, 0.8% of visitors become customers. At $600 per customer that is $24,000 of revenue.
What the result means — and what it does not
- It shows where people drop out, not why.
- With small numbers, a few people more or less move the percentages a lot; compare over longer periods.
Common questions
Which stage should I improve first?
Not simply the one with the lowest percentage — a website visitor-to-lead rate is almost always far lower than a booking-to-customer rate. Compare each step with its own past performance, and look at where a realistic improvement adds the most customers.
What if my stages are different?
Use the closest match: for example, quote requests as leads and quotes sent as bookings. Leave a stage equal to the one before it if you do not have it.
Why does the calculator reject my numbers?
Each stage should be a subset of the one before it. If you have more bookings than leads, some bookings probably came from outside this funnel or a different period.
