How to estimate experiment duration with your AI

Connect your traffic data to your agent to turn sample size requirements into a calendar schedule.

Short answer

How long will my A/B test take to run?

Your AI calculates the number of days required by comparing your daily traffic against the necessary sample size for statistical significance. You'll get a specific day count and a breakdown of the math used to reach it.

The results you get

What your AI calculates

Once you provide your traffic numbers, your agent delivers these specific outcomes.

TIMELINE

Total days required

The AI uses estimate_test_duration to tell you exactly how many days the test must run to hit your target sample size.

TRAFFIC

Daily volume check

The agent confirms if your current daily visitor count is sufficient to reach significance within a reasonable window.

SENSITIVITY

Minimum detectable effect

You'll see how changes in your expected lift impact the length of the experiment.

HUMAN

Manual adjustments

You decide if the calculated duration fits your business cycle or if you need to adjust your traffic assumptions.

The workflow

What your AI does when the data arrives.

The AI handles the statistical heavy lifting so you don't have to use a calculator.

  1. Analyze traffic

    The agent looks at your current visitor patterns to establish a baseline for daily volume.

    estimate_test_duration

  2. Calculate sample size

    It determines the total number of users needed to achieve the statistical power you requested.

    estimate_test_duration

  3. Project duration

    The AI divides the required sample size by your daily traffic to find the total runtime.

    estimate_test_duration

  4. Verify constraints

    The agent checks if the test duration conflicts with common business constraints like seasonality.

  • Estimate how many days an A/B test will take if I have 5,000 visitors a day and need a 5% lift.

  • Based on my Google Analytics data, how long should I run this experiment for a 2% conversion increase?

  • Calculate the duration for a test with 1,200 daily users and a required sample size of 10,000.

  • If I want to detect a 10% change in checkout rate with 3,000 daily sessions, how many days do I need?

FAQ

How the calculator behaves

  • 01

    Can the AI run the actual A/B test for me?

    No. The AI only calculates the required duration. You must use your own testing platform to run the experiment.

  • 02

    Does it connect directly to my website traffic?

    The AI uses the traffic numbers you provide in the chat to perform the calculation.

  • 03

    Can the AI change my experiment settings in other tools?

    No. This MCP is read-only for calculations. It cannot modify settings in your testing software.

  • 04

    What happens if my traffic fluctuates?

    The calculation is based on the specific daily volume you give it. If traffic changes, you should ask for a new estimate.

  • 05

    Will the AI tell me if my sample size is too small?

    Yes. If the required sample size is unrealistic for your traffic, the AI will report the resulting duration.
