What Is an AB Test Calculator?

An AB Test Calculator is an online tool that calculates and compares the conversion rates of two groups—commonly labeled Group A and Group B. A conversion can be any measurable action, such as:

  • Making a purchase
  • Signing up for a newsletter
  • Downloading an app
  • Clicking a link or button

By entering the number of conversions and visitors for each group, the calculator instantly provides:

  1. Conversion Rate of Group A
  2. Conversion Rate of Group B
  3. The difference between the two conversion rates

This data helps identify which version of your website, ad, or campaign is performing better and by how much.

How to Use the AB Test Calculator

Using the AB Test Calculator is simple and doesn’t require any technical expertise. Here’s a step-by-step guide:

  1. Input Group A Data:
    • Enter the total number of conversions for Group A in the “Group A Conversions” field.
    • Enter the total number of visitors for Group A in the “Group A Visitors” field.
  2. Input Group B Data:
    • Enter the total number of conversions for Group B in the “Group B Conversions” field.
    • Enter the total number of visitors for Group B in the “Group B Visitors” field.
  3. Calculate Results:
    • Click the Calculate button. The calculator will display the conversion rate for both groups and the difference between them.
  4. Reset for New Data:

Example of AB Test Calculator in Action

Imagine you run an online store and want to test two versions of your product page:

  • Group A: Original page
  • Group B: Redesigned page

You collect the following data:

  • Group A: 50 conversions out of 500 visitors
  • Group B: 65 conversions out of 500 visitors

Using the AB Test Calculator:

  • Conversion Rate A = (50 ÷ 500) × 100 = 10%
  • Conversion Rate B = (65 ÷ 500) × 100 = 13%
  • Difference = 13% − 10% = 3%

From this result, you can conclude that the redesigned page increased conversions by 3%, indicating that Group B outperformed Group A.
