A/B Testing Hosting Cost Per-User Calculator Examples
Worked examples showing how active users, fixed fees, bandwidth, and storage affect A/B testing hosting cost per user.
These examples show how the calculator handles small pilots, established experimentation programs, and higher-volume setups. The figures are planning estimates and use monthly costs, average per-user usage, and entered per-GB rates.

How to Read Your Results
Cost per active user is the monthly total divided by the monthly active-user count, not a charge billed to each individual user.
Total monthly hosting cost combines fixed infrastructure and platform fees with the estimated metered data costs.
Monthly bandwidth and stored-data outputs help identify whether transfer or storage is likely to be a meaningful cost driver.
The annual estimate simply multiplies the monthly result by 12; it does not project growth, discounts, or pricing changes.
Round small per-user figures carefully. A displayed $0.01 or $0.02 can represent a more precise underlying amount.
Assumptions & Important Notes
- Per-user bandwidth and storage figures are monthly averages measured in MB.
- All active users are assumed to have similar experiment-related usage.
- The entered rates are assumed to be effective monthly rates for the applicable provider and region.
- Fixed hosting and platform costs are assumed to recur every month.

Frequently Asked Questions
What is a realistic bandwidth-per-user input for A/B testing?
Use observed infrastructure data when available. Include experiment assets, analytics events, API calls, and other test-related transfer that your cost estimate is intended to cover.
Why can the rounded per-user result look the same in different examples?
The calculator may display currency to two decimal places. Underlying values can differ even when both round to the same cent amount.
Can I use the examples for feature flags instead of A/B tests?
Yes. The same cost model can be used for feature-flag infrastructure when you can estimate active users, fixed charges, and per-user data usage.
Should I enter total registered users or monthly active users?
Use the number of users expected to be active in, exposed to, or tracked by the setup during the month.
