A/B Testing Hosting Cost (Annual) Calculator Examples
Worked examples showing how base hosting, extra variants, and platform fees affect annual A/B testing costs.
These examples illustrate how to turn hosting and experimentation inputs into an annual cost estimate. They use simple planning assumptions and are intended for budgeting comparisons rather than billing forecasts.

How to Read Your Results
The annual total includes normal hosting, extra variant capacity, and the annual platform fee.
The added annual testing cost excludes base hosting and isolates the estimated cost of experimentation.
The average monthly result is the annual total divided by 12; it is not necessarily the amount billed each month.
Compare scenarios using consistent assumptions about traffic, variant duration, and included platform services.
Assumptions & Important Notes
- Each entered variant remains active for a full year.
- The per-variant cost is an average monthly estimate.
- Platform fees are entered as annual fixed costs.
- All amounts are shown in US dollars for illustration.

Frequently Asked Questions
Can I use the examples for a short A/B test?
Yes, but reduce the annualized variant cost to reflect the months the variant will actually run.
Why does the annual total include base hosting?
The calculator reports the full cost of operating the hosted testing environment, not only the added experiment cost.
What if variants share the same servers?
Use a lower or zero cost per variant if there is no measurable extra capacity cost.
Can the platform fee be zero?
Yes. Enter zero when no separate annual experimentation software fee applies.
