Why this isn't trivial
The part people underestimate: onboarding conversations are front-loaded per new user, so cost tracks your signup rate rather than your total user base. In practice the biggest savings come from scripting common steps and only invoking the LLM for genuinely open questions, so it is worth modelling before you commit.
How it's calculated
We estimate this by costing a typical onboarding conversation and multiplying by new signups per month. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Does onboarding cost scale with all users?+
No — it scales with new signups, since existing users onboard only once.
How do I reduce onboarding AI cost?+
Handle deterministic steps with UI and reserve the LLM for free-form help.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
