How much will a WhatsApp/SMS AI bot cost per message?
Before committing to a model, most teams running WhatsApp or SMS bots want to estimate a messaging bot's AI cost per message. 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: short messaging turns keep per-message tokens low, so total cost is driven by sheer message volume. In practice the biggest savings come from keeping replies terse and stateless where possible, so it is worth modelling before you commit.
How it's calculated
We estimate this by costing a short message exchange and scaling by monthly message volume (LLM cost only; carrier fees are separate). 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 this include WhatsApp/SMS carrier fees?+
No — this is the AI/LLM cost only; messaging platform fees are billed separately.
Why keep messaging replies short?+
Output tokens cost most; concise replies keep per-message AI cost minimal.
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.
