A/B Testing Calculator helps you plan and evaluate A/B tests: work out how many users you need for a reliable result, and find the test winner with statistical significance in mind. BEFORE THE TEST — SAMPLE SIZE Set your baseline rate, expected uplift, reliability and power — and the app calculates how many people should see each variant. Works for open rate, click rate and order conversion. AFTER THE TEST — RESULTS Enter the number of conversions and the sample size for each variant (up to 5) — the app shows conversion rates, confidence intervals and a clear verdict: which variant is better and whether you can trust the result. FEATURES • Two calculators: sample size and results evaluation • Compare up to 5 variants at once • Confidence intervals and statistical-significance testing • Clear explanations without statistical jargon • Copy any result with one tap Great for marketers, product managers and analysts.
