Drop Off Rate Calculator

Analyze your funnel performance by calculating abandonment percentages.

Drop Off Rate: 0%
Conversion Rate: 0%
Total Drop-offs (Lost Users): 0
Total Retained: 0

Understanding Drop Off Rate

The Drop Off Rate (often interchangeably used with Abandonment Rate) is a critical Key Performance Indicator (KPI) in digital marketing and user experience (UX) analysis. It measures the percentage of visitors who leave a specific conversion funnel, page, or process without completing the intended action.

Whether you are analyzing a checkout process, a signup form, or a specific navigation path on your website, understanding where and why users drop off is the first step toward Conversion Rate Optimization (CRO).

How to Calculate Drop Off Rate

To calculate the drop off rate, you need two key metrics: the number of visitors who entered the step and the number of visitors who successfully completed it. The formula identifies the portion of users lost during that specific step.

Drop Off Rate = ((Visitors at Start – Visitors at End) / Visitors at Start) × 100%

Example: If 1,000 users land on your checkout page, but only 650 users proceed to the payment confirmation page:

  • Visitors Start: 1,000
  • Visitors End: 650
  • Drop-offs: 1,000 – 650 = 350
  • Calculation: (350 / 1,000) × 100 = 35% Drop Off Rate

Drop Off Rate vs. Bounce Rate

While both metrics involve users leaving, they differ in context:

  • Bounce Rate: Refers to users who land on a page and leave without interacting or visiting a second page. It is a single-page session metric.
  • Drop Off Rate: Can apply to any step in a multi-step sequence. A user might view three pages and then "drop off" at the fourth step of a checkout flow.

High Drop Off Rates: Common Causes

If this calculator reveals a high drop off percentage, consider investigating these common issues:

  • Technical Issues: Slow page load speeds or broken buttons.
  • Complex Forms: Asking for too much information or poor UI design.
  • Unexpected Costs: Shipping fees or taxes appearing late in the checkout.
  • Lack of Trust: Missing security badges or unclear return policies.

Optimizing Your Funnel

Reducing your drop off rate directly increases your conversion rate. By using analytics tools (like Google Analytics) to visualize the flow, you can pinpoint the exact step causing friction. Once identified, A/B testing different designs, simplifying copy, or reducing form fields can help retain more users.

function calculateDropOff() { // Get input elements var startInput = document.getElementById("visitorsStart"); var endInput = document.getElementById("visitorsEnd"); var resultsArea = document.getElementById("resultsArea"); var errorMsg = document.getElementById("errorMsg"); // Parse values var startVal = parseFloat(startInput.value); var endVal = parseFloat(endInput.value); // Reset display errorMsg.style.display = "none"; resultsArea.style.display = "none"; // Validation if (isNaN(startVal) || isNaN(endVal)) { errorMsg.innerText = "Please enter valid numbers for both fields."; errorMsg.style.display = "block"; return; } if (startVal startVal) { errorMsg.innerText = "Visitors remaining cannot exceed total visitors at the start."; errorMsg.style.display = "block"; return; } if (endVal < 0) { errorMsg.innerText = "Visitors remaining cannot be negative."; errorMsg.style.display = "block"; return; } // Calculations var dropOffs = startVal – endVal; var dropOffRate = (dropOffs / startVal) * 100; var conversionRate = (endVal / startVal) * 100; // Display Results document.getElementById("resDropRate").innerText = dropOffRate.toFixed(2) + "%"; document.getElementById("resConvRate").innerText = conversionRate.toFixed(2) + "%"; document.getElementById("resLost").innerText = dropOffs.toLocaleString(); document.getElementById("resRetained").innerText = endVal.toLocaleString(); // Show result box resultsArea.style.display = "block"; }
