CRO Tools & Calculators
Use these tools to size experiments, diagnose funnel leaks, model revenue upside, and pressure-test unit economics before you change pages, onboarding, pricing, or acquisition.
Start with the problem, not the tool
Most teams do not need more calculators. They need the right calculator for the bottleneck they are facing right now.
Size the test
Use the A/B test calculator when the main question is whether an experiment is worth the traffic and runtime.
Open A/B Test CalculatorFind the economic leak
Use churn and CAC/LTV when growth feels expensive and you need to know whether retention or acquisition is the bigger problem.
Open CAC/LTV CalculatorQuantify upside first
Use conversion rate and revenue impact tools when you need a clearer business case before touching pages, offers, or pricing.

These are the tools most likely to change what you build, test, or prioritize next.
A/B Test Calculator
Traffic and feasibility
Estimate sample size, confidence, and expected runtime before you commit traffic to a low-signal experiment.
- Visitors needed per variation
- Estimated test duration
- Confidence and power settings
- Guidance on realistic detectable lift
Churn Calculator
Logo churn and revenue churn
Quantify logo churn, revenue churn, lifetime, and the gross-profit upside of reducing retention leakage.
- Customer and revenue churn
- Lifetime and gross-margin LTV
- Saved MRR at target reduction
- Retention priority signals
CAC/LTV Ratio Calculator
Efficiency and payback
See whether acquisition is economically healthy, how long payback takes, and whether conversion or retention is the better lever.
- Simple and advanced modes
- CAC, LTV, and payback period
- Benchmark ranges
- Improvement levers by ratio quality
Revenue Impact Calculator
Revenue modeling
Translate conversion improvement into monthly and annual revenue so the opportunity is concrete before you prioritize a project.
- Current vs projected revenue
- Monthly and annual uplift
- Improvement sensitivity
- Context for budgeting CRO work

Funnel Optimization Calculator
Identify which funnel stage has the biggest impact on conversion rate.
Templates and Frameworks
Use these when the team needs structure around funnel mapping or growth planning, not just a single point estimate.
Need diagnosis beyond the math?
These calculators are useful for direction. The next step is deciding which bottleneck matters most and what sequence of fixes is actually worth shipping.
