A/B Testing Cloud Cost Calculator Examples
Worked examples showing how traffic, variants, event volume, and test duration affect estimated A/B testing cloud costs.
These examples use illustrative cloud pricing to show how the calculator handles small validation tests, higher-traffic experiments, and tests with heavier event instrumentation. Replace the rates with your own provider and platform costs.

How to Read Your Results
Total cloud cost is an estimate of incremental experiment-related spend, not a full cloud bill.
Compare the infrastructure, event, and storage components to identify the main cost driver.
Cost per participant helps compare tests of different traffic volumes.
A low per-participant cost can still produce a meaningful total at high traffic.
Add costs not represented by the inputs, such as egress or vendor fees, when they are material.
Assumptions & Important Notes
- Each example uses a 30-day month for monthly prices.
- All variants are assumed to have equal incremental infrastructure cost.
- Event rates and storage rates are illustrative rather than provider-specific.
- Test data is assumed to accumulate evenly and be retained only during the experiment.

Frequently Asked Questions
What is a typical A/B test cloud cost?
It varies with traffic, telemetry volume, variant infrastructure, provider rates, and retention. The examples illustrate calculation patterns rather than typical pricing.
Why can a high-traffic test have a lower cost per participant?
Fixed or semi-fixed infrastructure costs are spread across more participants, although total event-processing cost can still rise substantially.
When does storage become a significant A/B testing cost?
Storage can matter when the test generates large logs, recordings, exports, or data retained beyond the experiment. For short tests with low-cost object storage, it may be comparatively small.
Can these examples be used for feature flag costs?
Yes. Use the incremental traffic, telemetry, compute, and data storage associated with the feature flag experiment.
