How To Estimate Requests Per User/Month
Request volume is usually the strongest cost multiplier. Get this assumption roughly right first.
Question
How can I quickly estimate requests per user/month for AI pricing math?
Quick answer
Formula: requests_per_user_month = weekly_sessions * requests_per_session * 4.3
- Assumption: model both p50 and p90 user behavior.
- Assumption: include retries and follow-ups in requests/session.
- Assumption: revisit estimate after major UX or model changes.
Example: 3 weekly sessions and 6 requests/session gives 77.4 requests/user/month.
Simple Estimation Method
- Start with expected weekly usage sessions per user.
- Multiply by average requests per session.
- Multiply by 4.3 for monthly estimate.
- Model p50 and p90 scenarios to reflect heavy users.
