Example of Drop Off Percentage Calculator
Let’s say you launched a landing page that had 1,000 visitors. Out of those, only 300 completed the sign-up process.
Initial Value = 1000
Final Value = 300
Apply the formula:
Drop Off Percentage = ((1000 – 300) ÷ 1000) × 100
Drop Off Percentage = (700 ÷ 1000) × 100 = 0.7 × 100 = 70%
This means 70% of users dropped off before signing up, which may suggest a problem with the page design or offer clarity.
