Funnel conversion calculator (multi-step)

Name and count every stage of a funnel and get the pass-through rate of each step, its share of everyone who entered, the overall rate, the weakest step, the step that loses the most people — two different questions — and what lifting the weak one would be worth.

Enter People at each stage, from first to last, Value of one final conversion and the Funnel conversion calculator (multi-step) works out Overall conversion rate, Final conversions, Revenue generated, Value per person entering the funnel, Weakest step (lowest pass-through), Pass-through of that step, People stopping at the weakest step, Step losing the most people, People lost at that step, Extra conversions if the weakest step matched the median of the others, Extra revenue from that same gain straight away. For instance, with People at each stage, from first to last = 10000, 2400, 780, 260, 74 and Value of one final conversion = $180.00 it returns Overall conversion rate = 0.74%, Final conversions = 74 and Revenue generated = $13,320.00.

  2. Read the result instantly: Overall conversion rate, Final conversions, Revenue generated, Value per person entering the funnel, Weakest step (lowest pass-through), Pass-through of that step, People stopping at the weakest step, Step losing the most people, People lost at that step, Extra conversions if the weakest step matched the median of the others, Extra revenue from that same gain.

Frequently asked questions

How does the Funnel conversion calculator (multi-step) work?

It takes People at each stage, from first to last and Value of one final conversion and derives Overall conversion rate, Final conversions, Revenue generated, Value per person entering the funnel, Weakest step (lowest pass-through), Pass-through of that step, People stopping at the weakest step, Step losing the most people, People lost at that step, Extra conversions if the weakest step matched the median of the others and Extra revenue from that same gain from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

2 values: People at each stage, from first to last and Value of one final conversion ($). Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With People at each stage, from first to last = 10000, 2400, 780, 260, 74 and Value of one final conversion = $180.00, the calculator returns Overall conversion rate = 0.74%, Final conversions = 74 and Revenue generated = $13,320.00. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using People at each stage, from first to last = 10000, 2520, 858, 299, 89 and Value of one final conversion = $360.00 instead, Overall conversion rate goes from 0.74% to 0.89% — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to People at each stage, from first to last = 10000, 2400, 780 and Value of one final conversion = $1.00, Overall conversion rate comes out at 7.8%. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Finding where a journey leaks: which step loses the most people relative to its own traffic, what fixing it would be worth, and how many visitors a test needs before its result means anything.

What is the most common mistake?

Fixing the step that loses the most people. That is almost always the first one, simply because everybody starts there — the weak step is the one with the worst rate relative to the traffic reaching it.

What is the difference between the Funnel conversion calculator (multi-step) and the Conversion rate calculator?

This one returns Overall conversion rate and Final conversions; the Conversion rate calculator returns Conversion rate and Visitors per conversion. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

CTR calculator is the closest one after this: Compute the click-through rate (CTR) from clicks and impressions.

Where do the figures come from, and how current are they?

The maths is exact for the counts you enter, and it assumes each step is measured over the same period and the same population. Sample-size guidance follows the standard test for two proportions.
