How much does a chatbot cost?
Anywhere from nothing to five figures a year, and the sticker price on the homepage will not tell you which. What decides your bill is the billable unit — what the vendor counts when they charge you.
The short answer
- Entry flat-rate plans
- Roughly $14–$16 a month when billed annually, with a conversation cap you will eventually hit.
- Seat-based suites
- About $55–$115 per agent per month. You pay for humans whether the bot does their work or not.
- Usage-based
- Roughly $0.40–$0.99 per conversation or per resolution, which is where bills get unpredictable.
- Full custom build
- Commonly cited at $15,000–$40,000 up front plus $200–$800 a month to run, with no per-conversation charge.
- Rule-based, self-hosted
- $0 per month. There is no server call, so there is nothing to meter.
Run your own numbers
The same volume produces wildly different bills depending on the model. Move the sliders and watch which one wins — the answer changes as you grow, which is the entire point.
Rates used are the published market ranges cited below, not any single vendor's quote. Everything runs in your browser — nothing is sent anywhere.
The five ways chatbots get priced
Ask five vendors what they charge and you get five numbers that cannot be compared, because each one is counting something different.
A fixed fee for every team member with access, typically $55–$115 each. Common in live-chat suites that bolted a bot on later.
Turns expensive when: your team grows, or automation rises and you keep paying for seats the bot made unnecessary.
You pay whenever a visitor starts talking, resolved or not, commonly around $0.40–$1.00 each.
Turns expensive when: traffic spikes. A good month for marketing is a bad month for this invoice.
You only pay when the bot actually finishes the job. Intercom's Fin popularized it at about $0.99 per resolution, usually on top of seat fees.
Turns expensive when: the bot gets good. See below — this one deserves its own section.
You buy a bucket of message credits. The trap is that "message" means something different on every platform, so buckets are not comparable.
Turns expensive when: you run out mid-month and buy top-ups at retail.
One predictable price per tier. Widely considered the sanest option for a growing small business precisely because nothing surprises you.
Turns expensive when: you sit just under a ceiling and get pushed to the next tier, or you overpay for headroom you never use.
You pay to have it built and then own it. No per-conversation tax, ever. Enterprise figures run $15k–$40k up front; a scoped small-business build is far less.
Turns expensive when: your volume is low. Below a few thousand chats a month, renting usually wins.
The per-resolution growth trap
This is the one nobody explains before you sign, and it is genuinely counterintuitive.
Per-resolution pricing sounds like the fairest model on the list. You only pay when the bot works. But your bill is volume multiplied by resolution rate — so every improvement to the bot raises what you owe. Tune it well and you are punished for it.
| Bot resolves | At 2,000 chats/mo | Annual cost at $0.99 |
|---|---|---|
| 40% (poor) | 800 resolutions | $9,504 |
| 65% (typical) | 1,300 resolutions | $15,444 |
| 85% (excellent) | 1,700 resolutions | $20,196 |
The better it gets, the more it costs. Industry resolution rates are climbing, which means this line item is climbing for everyone on that model — and seat fees usually sit on top of it.
What is not on the pricing page
The sticker price is one layer. These are the ones that show up on the invoice.
- A helpdesk subscription you did not want. Several AI agents require the vendor's support platform to run at all. The bot is priced separately from the thing it needs to exist.
- Copilot and QA add-ons, per agent, per month. The features demoed to you are frequently a separate line item from the plan you were quoted.
- Implementation and professional services. Onboarding fees are standard above the self-serve tier and are often quoted only after you are committed.
- Your own engineering time. Setup, content ingestion, tuning, and ongoing configuration are real hours. They do not appear on anyone's pricing page but they come out of your budget.
- Messaging channel fees. WhatsApp charges per conversation regardless of which chatbot platform you use, so that cost rides along on top of whatever you are already paying.
- The next tier. Caps are set where growing businesses hit them. Budget for the tier above the one you are buying, because that is the one you will be on.
So what should you actually pay?
Volume decides it, and the crossover points are reasonably consistent.
Under a few hundred conversations a month
Renting is fine and an owned build is hard to justify. But this is also exactly the range where a rule-based bot handles nearly everything, because at that volume your questions are repetitive and your answers are fixed. If hours, service area, pricing ranges and booking cover 90% of what people ask, you are about to pay a subscription for a FAQ.
A few thousand a month
Flat-tier pricing usually wins on predictability. Per-resolution starts getting uncomfortable here, and seat-based stops making sense if the bot is handling most of the load.
Tens of thousands a month
The math flips toward owning it. A fixed build cost with near-zero marginal cost beats any rented model once volume is high enough, which is the whole reason large companies build instead of rent.
One thing worth knowing before you compare
Drift, for years the default reference point in any chatbot pricing comparison, was sunset by Salesloft in March 2026. A lot of the comparison articles still ranking on this topic were written before that. If a roundup is recommending it, the roundup is stale — check the date on anything you read about this, including this page.
Figures here are drawn from published 2026 pricing research across multiple independent comparisons, including per-resolution rates around $0.99, seat pricing in the $55–$115 range, usage pricing around $0.40–$1.00, and custom build figures of $15k–$40k plus $200–$800 monthly. Vendor pricing changes often and we do not restate any single company's current plan as fact — verify on the vendor's own pricing page before you buy. Last reviewed September 2026.
Chatbot cost questions
How much does a chatbot cost per month?
Entry flat-rate plans start around $14–$16 a month billed annually. Seat suites run roughly $55–$115 per agent. Usage models charge about $0.40–$0.99 per conversation or resolution. A rule-based bot you host in your own page costs nothing monthly, because there is no server call to meter.
What is per-resolution pricing?
You pay each time the bot closes a conversation without a human, commonly around $0.99. The catch is that your bill rises as the bot improves, since a higher resolution rate means more billable resolutions.
Which pricing model is cheapest?
It depends entirely on volume. Per-resolution is often cheapest below about 500 conversations a month and among the priciest at high volume. Flat tiers are the most predictable while you grow. An owned build wins once volume is high because marginal cost is near zero.
What hidden costs should I expect?
A required helpdesk subscription, per-agent copilot or QA add-ons, implementation fees, your own engineering hours, messaging channel fees like WhatsApp's per-conversation charge, and the next pricing tier you will get pushed into.
How much does a custom chatbot cost?
Enterprise builds are commonly cited at $15,000–$40,000 up front plus $200–$800 a month. A scoped build for a single small business costs far less. What defines the category is that there is no per-conversation charge once it exists.
Can a chatbot actually be free?
Yes, if it is rule-based and lives in your own page. The code runs in the visitor's browser with no server call, so there is nothing for anyone to meter. The trade is that it cannot answer what nobody scripted.
What about the $199 install you offer?
That is a one-time fee to put the free bot on your site and host the file, including the first 12 months of hosting, then $49 a year. It is not a subscription to the chatbot — the chatbot is free either way. You are paying for the hour of work.
Or find out what $0 gets you
Before you price anything, spend two minutes building the free version and see whether it already answers the questions you actually get asked. If it does, you are done. If it does not, now you know exactly what you are shopping for.
