A/B Testing Token Usage (Annual) Calculator Examples
Worked examples showing how traffic, test allocation, requests, token volume, and price affect annual A/B testing token estimates.
These examples show how an annual A/B testing token forecast changes across small pilots, established experimentation programs, and higher-volume AI experiences. All figures are planning estimates using the stated assumptions.

How to Read Your Results
Annual token usage is the total estimated input and output tokens across all planned test requests.
Annual AI requests show the request volume behind the token estimate and can help identify where usage is generated.
Participants per test represents annual test exposure, not necessarily unique people.
Tokens per variant is an even-split reference figure; actual variant consumption can differ.
Estimated cost uses only the price per million tokens that you enter, so it should be treated as a budget estimate.
Assumptions & Important Notes
- Monthly eligible traffic is stable enough to annualize using 12 months.
- Each planned test receives the same entered percentage of eligible traffic.
- Average request and token behavior is consistent across tests unless separately modeled.
- The selected price per million tokens reflects the anticipated model mix and pricing basis.

Frequently Asked Questions
How do I estimate token usage for a small A/B test?
Use the expected eligible audience, allocate only the traffic entering the test, then multiply by requests per participant and combined tokens per request.
Can I use different assumptions for each A/B test?
This calculator applies one set of assumptions to all tests. For different traffic or token profiles, calculate each test separately and add the results.
What does tokens per variant mean in the examples?
It is the total annual token estimate divided evenly by the number of variants. It is a planning average rather than a measurement of actual variant behavior.
What if participants make more requests in one variant?
Use a weighted or separate estimate for each variant, because an even split will not capture different request frequencies.
Should I add a buffer to the example cost?
A planning buffer may be useful when real usage is uncertain, but the appropriate amount depends on observed variability, pricing, and implementation details.
