Maximum Experiments Calculator

Determine your annual A/B testing capacity based on traffic, conversion rates, and desired statistical precision.

Adjust these values to match your specific context.

Daily Traffic (visitors)

Baseline Conversion Rate (%)

Minimum Detectable Effect (%)

Confidence Level (%)

Statistical Power (%)

Parallel Testing Uplift (%)

Recalculate after changing input values to see updated results.

Enter your average daily traffic and baseline conversion rate.
Set your desired Minimum Detectable Effect (MDE) - the smallest change you aim to detect.
Configure your statistical confidence level (e.g., 95%) and power (e.g., 80%).
Estimate any uplift from running tests in parallel using the slider.
Click "Calculate Capacity" to view your annual testing potential and related metrics.
Analyze the "MDE vs. False Negative Risk" chart to understand detection trade-offs.
