What does an AI email-drafting feature cost per user?
Before committing to a model, most productivity and CRM product teams want to estimate an AI email-drafting feature's cost per user. This page does exactly that with an interactive calculator, so instead of guessing you get a concrete monthly cost grounded in today's provider prices.

Why this isn't trivial
The part people underestimate: power users draft many emails a day, so a low per-draft cost still adds up per active user each month. In practice the biggest savings come from limiting draft length and caching common templates and signatures, so it is worth modelling before you commit.
How it's calculated
We estimate this by estimating tokens per draft and drafts per user per day, applying model rates, then multiplying by working days to get a per-user monthly cost. 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
How many drafts should I assume per user?+
Model both a typical and a heavy user — the heavy tail usually sets your real per-user cost.
Do input or output tokens cost more here?+
Output dominates when drafts are long; short reply suggestions shift cost toward input context.
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.
