Example output
Sample, not a benchmark: 10,000 visitors, then 40 percent, 25 percent, and 20 percent. Stage 1 is 4,000. Stage 2 is 1,000. Customers are 200. The marketing funnel calculator does not round 4,000 before multiplying by 25 percent.
How to use it
- Enter the visitors at the top of this path.
- Enter each rate as the percent of the previous stage.
- Read the three counts. Two decimals are display only.
- Take the customer count to the CAC and LTV calculator when you know the spend.
FAQ
What happens when visitors are zero?
A typed zero is a real count, and every stage is zero. A blank or whitespace-only step is required and is not treated as zero.
Are these rates a benchmark?
No. The rates are the ones you type. The page does not fill in an industry average.

- Google Ads Help: conversion rate definition Each stage is the previous count times the rate you type. That rearranges conversions divided by tracked ad interactions. The 50 from 1,000 example on that page is not this chain and is not a benchmark.
- Google Analytics Help: session key event rate GA4 defines session key event rate as sessions in which a key event happened, divided by total sessions. This calculator does not count sessions. Each stage is still the previous count times the typed rate.
