What is Abandonment Rate?

Abandonment rate, often referred to as churn rate or dropout rate in various contexts, is a key metric used to understand user engagement and the effectiveness of a process, funnel, or service. It quantifies the percentage of users or sessions that begin a specific process but do not complete it. This could apply to website checkouts, online forms, multi-step applications, onboarding flows, or even a series of tasks within a game or application.

A high abandonment rate can signal underlying issues such as a confusing user interface, technical glitches, a lengthy or complicated process, lack of perceived value, or external distractions. Analyzing and reducing abandonment rate is crucial for improving conversion rates, customer satisfaction, and ultimately, business success.

How to Calculate Abandonment Rate:

The formula for abandonment rate is straightforward:

Abandonment Rate = ( (Sessions Started – Sessions Completed) / Sessions Started ) * 100

In simpler terms, it's the number of users who left the process, divided by the total number of users who started it, expressed as a percentage.

Example Calculation:

Let's say a company runs an online survey.

  • Total number of users who started the survey (Sessions Started): 1500
  • Total number of users who completed the survey (Sessions Completed): 900
Using the formula:
  • Number of users who abandoned = 1500 – 900 = 600
  • Abandonment Rate = (600 / 1500) * 100 = 40%
This means 40% of users who started the survey did not complete it. This information can prompt an investigation into why so many users dropped off.

function calculateAbandonmentRate() { var sessionsStartedInput = document.getElementById("sessionsStarted"); var sessionsCompletedInput = document.getElementById("sessionsCompleted"); var resultDiv = document.getElementById("result"); var sessionsStarted = parseFloat(sessionsStartedInput.value); var sessionsCompleted = parseFloat(sessionsCompletedInput.value); if (isNaN(sessionsStarted) || isNaN(sessionsCompleted)) { resultDiv.innerHTML = "Please enter valid numbers for both fields."; return; } if (sessionsStarted < 0 || sessionsCompleted sessionsStarted) { resultDiv.innerHTML = "Sessions completed cannot be greater than sessions started."; return; } if (sessionsStarted === 0) { resultDiv.innerHTML = "Abandonment Rate: 0% (No sessions started)."; return; } var abandonedSessions = sessionsStarted – sessionsCompleted; var abandonmentRate = (abandonedSessions / sessionsStarted) * 100; resultDiv.innerHTML = "Abandonment Rate: " + abandonmentRate.toFixed(2) + "%"; }
