Story

Finding 1. Customer churn is 7.9% across 1,800 customers.

Finding 2. Total monthly recurring revenue in scope is $92,080; churn therefore has direct recurring-revenue implications.

Finding 3. Value has the highest observed churn rate among the customer segments in the dataset.

A/B Test Planner & Decision Readout

Estimate a two-sided, two-proportion test sample size before launching a controlled experiment. Planning estimates are not a substitute for a pre-registered analysis plan.

Assumes independent users, a binary outcome and equal allocation. Adjust for attrition, clustering, multiple comparisons and practical significance before launch.

A/B test planner: quantify the decision before rollout

Use this planning calculator to estimate a simple two-arm test. Inputs are illustrative planning assumptions—not observed results or a substitute for a formal power analysis.

Variant A—participants
Variant B—participants
Total—participants
Target rate B—planning target

Planning method: normal approximation for two independent proportions, equal allocation. Validate assumptions with a statistical package before running a consequential experiment; account for clustering, multiple tests, attrition and business guardrails.
