Straight answers,
no stats degree required.
abtestcalculators.com exists for one reason: most marketers, growth hackers and CRO specialists don't need a PhD in statistics to know if their test won. They need a clear answer, in plain English, in under a minute.
Built for the people actually running the tests.
Every A/B testing calculator online assumes you already know what a p-value is, what "statistical significance" really means, or how to pick between frequentist and Bayesian methods. For most people running experiments — PPC managers, SEO leads, CRO consultants, landing page designers, founders — that's a wall.
The result? Tests get called too early. Winners get rolled out that were noise. Losers get killed that would have converted. Budgets get burned on the wrong variant. And "we'll just A/B test it" becomes a phrase everyone says and no one trusts.
abtestcalculators.com flips it. You give us the numbers. We give you the answer — with a probability, an uplift range and a plain-English verdict. If you want the statistics underneath, they're there. If you don't, you never have to see them.

I've spent years running paid media, SEO and CRO programs for brands large and small. Along the way I've watched too many good ideas get killed by bad statistics — and too many bad ideas get shipped because a dashboard turned green too early.
abtestcalculators.com is the toolkit I wish existed when I started: honest, fast, and designed for marketers first, statisticians second.
