How to use thisPlot every stage of your funnel from top (visitors / leads) to bottom (paying / retained). The biggest percentage drop is your bottleneck — fix that stage first. Doubling a 30% step from 30% to 60% has more impact than tripling a 5% step.

What is the funnel conversion calculator?

A funnel is the sequence of stages a user moves through: visitor → signup → activation → conversion → retention. Each stage has a conversion rate from the previous one.

This calculator surfaces step conversion rates AND the biggest single drop — the one stage where focused work has the most leverage.

Why this matters for founders & operators

Founders often try to optimize the wrong stage. If your visitor-to-signup is 8% and your trial-to-paid is 5%, doubling visitor-to-signup feels great but actually moves total conversion less than fixing trial-to-paid.

The simplest rule: find the lowest step conversion rate, fix it first. The biggest drop is usually the biggest opportunity.

FAQ

What's a healthy overall funnel conversion (visitor → paying)?+
0.3-2% for typical SaaS. Higher for tighter targeting; lower for top-of-funnel content marketing.
Should I include retention as a funnel stage?+
Yes for SaaS — retained customers are the only ones generating LTV. Funnels that stop at 'paid' miss the most important number.
How often should I review the funnel?+
Monthly at minimum. Big product or marketing changes should trigger an immediate funnel review.
Should I segment the funnel by source?+
Yes for serious analysis. Different acquisition channels have very different funnel shapes — a blended view hides the truth.
