Funnel Drop-Off Calculator
Analyse multi-step funnel conversion from stage counts, step conversion rates, drop-off counts, bottlenecks, overall conversion, and gap to target final conversion.
Funnel stages
Enter counts in order from top of funnel to final conversion.
Keep stage definitions consistent. Counts should usually move downward as the funnel narrows.

Funnel maths shows where users leave. It does not prove cause, attribution, or A/B test significance.
Funnel drop-off shows where conversion fails
A simple conversion rate says how many people reached the final action, but it does not show where users left the funnel. A landing page, signup form, onboarding step, trial start, or checkout can each lose a different share of users.
This calculator compares stage counts in order, then calculates step conversion, drop-off count, drop-off rate, overall conversion, the largest bottleneck, and the gap to a target final conversion rate.
Use it when the decision is about where to improve the funnel, not only whether the final percentage is high or low.
A final conversion rate can look weak without showing which stage caused the loss. Breaking the funnel into ordered stages makes the biggest leak visible.
This calculator uses stage counts to calculate step conversion, drop-off count, drop-off percentage, overall conversion, the largest bottleneck, and the gap to a target final conversion rate.
Use it with conversion rate calculator for simple one-step rates and statistical significance calculator when completed A/B test variants need a two-proportion check.
Worked example: visitors, sign-ups, activation, trial, paid
A funnel with 25,000 visitors, 4,200 sign-ups, 1,850 activated users, 960 trials, and 310 paid customers has a final conversion rate of about 1.24%.
The biggest step loss may be activation, not checkout. That changes the work: onboarding and first-value improvements may beat paid traffic or pricing experiments.
The target gap shows how many additional final conversions are needed for the entered final conversion target.
If 25,000 visitors produce 4,200 sign-ups, 1,850 activated users, 960 trials, and 310 paid customers, the final conversion rate is about 1.24%.
The largest drop-off may sit between sign-up and activation rather than trial and paid conversion. That points toward onboarding and first-value work instead of only acquisition spend.
A target final conversion rate turns the analysis into an action gap by showing how many extra final conversions the funnel needs.
What this calculator does not prove
It does not diagnose why users dropped, import analytics, attribute conversions to channels, calculate statistical significance, or decide experiment winners.
Use the conversion rate calculator for one simple visitors-to-conversions percentage. Use statistical significance when completed A/B test counts need a two-proportion check.
What this funnel drop-off calculator covers
This page should target funnel drop off calculator, funnel conversion calculator, multi step funnel calculator, conversion funnel drop off, and stage conversion rate calculator searches.
It calculates deterministic stage conversion and drop-off from manual counts. It does not diagnose cause, import analytics, attribute channels, calculate statistical significance, or decide A/B test winners.

Funnel drop-off: common questions
What is funnel drop-off?
It is the users lost between one funnel stage and the next, expressed as a count or percentage.
How is step conversion calculated?
Step conversion is the current stage count divided by the previous stage count.
Should counts always decrease?
Usually yes for a single funnel path. If they increase, check whether the stages use different definitions or overlapping audiences.
Is this an A/B test calculator?
No. It measures funnel loss. Use statistical significance tools to compare test variants.
How is this different from Conversion Rate?
Conversion Rate handles one denominator and one conversion count. This calculator handles several stages and shows where drop-off is largest.
