Founded by a Digital Marketer

As a digital marketer, I've seen too many great ideas fail because teams were intimidated by the statistical knowledge required for proper A/B testing. Complex formulas, confusing terminology, and expensive tools created barriers that prevented businesses from making data-driven decisions.

That's why I created A/B Test Calculators. I wanted to build a bridge between complex statistical theory and practical marketing needs. Every calculator, guide, and resource is designed with real marketers in mind—people who need reliable results without a statistics degree.

My goal is simple: if you can count conversions and visitors, you can run statistically valid A/B tests. No intimidating jargon, no hidden costs, just the tools you need to optimize with confidence.

The Problem

Statistical knowledge shouldn't be a barrier to optimization. Too many marketers avoid A/B testing because it feels too technical or expensive.

The Solution

Free, user-friendly tools that handle the complex math while providing clear, actionable insights that any marketer can understand and act on.
