Conversion rate & funnel calculator 2026

Find your conversion rate, your biggest funnel leak and what one extra point is worth.

Single page mode gives the conversion rate of a page and the rate needed for your target. Funnel mode reads up to six steps, from visitor to customer, and pinpoints the step that leaks the most against B2B benchmarks.

How to use the conversion rate calculator

Single page: enter visitors, conversions, the value of one conversion and the number of conversions you target. Multi-step funnel: enter the volume at each step, from visitors to customers. Leave a step at 0 to stop the funnel there.

The formulas

Conversion rate = conversions / visitors
Step rate = volume at step n / volume at step n−1
Main leak = the step with the lowest rate relative to its B2B benchmark
Value of +1 point = extra customers produced if that step converted one point better × revenue per customer
Rate needed = current rate × target / current result

B2B funnel benchmarks used

Visitor → lead around 2%, lead → MQL around 30%, MQL → SQL around 35%, SQL → opportunity around 60%, opportunity → won around 25%. They are orders of magnitude for B2B SaaS and services, to be adjusted to your deal size and sales cycle.

Why the funnel view changes the diagnosis

Most calculators stop at one division. In B2B the leak is rarely on the landing page: it often sits between MQL and SQL, where marketing and sales disagree on what a good lead is. The funnel view shows which step to fix first and what it is worth.

Before shipping a change, check that your traffic can prove it worked: the A/B test calculator tells you how many visitors and how many weeks you need.
