Drop-off Rate
Drop-off rate is the percentage of users who leave a specific step in your funnel without completing it.
What it means
Drop-off rate is the inverse of conversion rate. If 60% of users move to the next step, 40% drop off. It's the metric that tells you exactly where your funnel is leaking.
Drop-off happens at every step. The question isn't whether you have drop-off, but whether the rate is reasonable for that step. A signup step might naturally see 50% drop-off. A 'click confirm email' step should be closer to 10% drop-off. A 'view pricing page' to 'click upgrade' step might see 90% drop-off, which is also normal.
When drop-off is too high for a step, the fix is usually one of: friction (too many fields, too many clicks), confusion (unclear value or instructions), or trust (lack of social proof, sketchy design). Sometimes it's a technical bug that breaks the flow on a specific browser or device.
Why it matters
Drop-off rate tells you exactly where to focus. Fixing your worst drop-off step is almost always higher leverage than trying to improve every step a little. It's the SEO of conversion: high-impact changes hide in specific spots.
How to calculate drop-off rate
Drop-off Rate = ((Started - Completed) / Started) × 100
Divide the number of users who didn't complete a step by the number who started it, then multiply by 100.
Example with real numbers
Concrete example showing how this metric works in practice.
Scenario
200 users start your onboarding flow. 80 complete step 1. The other 120 leave without finishing it.
Calculation
(120 / 200) × 100 = 60%
What it means
Your step 1 drop-off rate is 60%. For an onboarding step, that's high. Worth checking what's happening on that page: is it asking for too much, too soon?
Common mistakes
Things people get wrong when measuring drop-off rate.
Mistake 01
Looking at total drop-off instead of step-by-step drop-off. The drop-off step is what matters, not the total.
Mistake 02
Not segmenting drop-off by device. Mobile drop-off rates are often much higher than desktop.
Mistake 03
Trying to fix every drop-off step at once. Pick the worst one first.
Mistake 04
Confusing drop-off with churn. Drop-off is funnel leakage during signup or onboarding. Churn is paying customers leaving over time.
How to track it
Define your funnel steps and track how many users reach each one. Subtract to get the drop-off at each step. Muro's Funnel Calculator and Conversion Drop Analyzer both visualize this automatically.

Common questions about drop-off rate
Drop-off rate is the percentage of users who abandon a step in your funnel without completing it. It's how you find specific leaks in your conversion flow.
Identify your worst drop-off step first, then look at the obvious causes: too many form fields, unclear next step, slow page load, or a bug on a specific device. Fix the one with the biggest impact, not all of them.
Drop-off happens during signup or onboarding (a new user leaves before becoming active). Churn happens later (an existing customer cancels). Different problems with different fixes.
