Chatbot Cost Calculator for Support Teams
A chatbot cost calculator estimates costs by adding the platform fee, model usage, setup work and human support; momo plans range from EUR 0 to EUR 399 per month. Separate those inputs before choosing a plan, so a low entry price does not hide usage charges or a plan limit that your team will outgrow.
Compare visible allowances before estimating the total
Compare published usage limits and add-on rules for Botpress and DocsBot with momo's included allowances. These figures compare stated allowances, not equivalent features or complete monthly totals.
Botpress and DocsBot subscription prices are not included here. Allowances and currency shown are the stated product details, not a full cost comparison.
Plan breakdown
Free
Free costs EUR 0. It includes 30 AI conversations as a one-time allowance, one agent and one team member. The plan also includes a website widget, helpdesk inbox, basic analytics and 2 MB of knowledge across up to 10 sources. The widget carries a momo badge. A Free AI conversation can contain up to 10 AI replies. The allowance is not a monthly refill, so use the one-time limit when judging whether the workflow fits before relying on it for steady traffic. There is no separate per-resolution fee or credit pack. The plan details do not state a charge for human handoff; the inbox is included.
Starter
Starter costs EUR 29 per month or EUR 319 per year. Yearly billing is 11 times the monthly price. The plan includes 500 AI conversations per month, one agent, two team members, the website widget and email channel, a helpdesk inbox, Help Center, basic analytics, and 20 MB of knowledge across up to 50 sources. It has no momo badge. Paid-plan AI conversations can hold up to 25 AI replies. Add staffing and model usage to the subscription when estimating the total, rather than assuming a per-resolution charge.
Growth
Growth costs EUR 129 per month or EUR 1,419 per year. It includes 2,000 AI conversations per month, three agents and five team members. Slack, API, Zapier and webhooks are included, alongside advanced analytics and 100 MB of knowledge across up to 200 sources. The included inbox gives the team a place to take over conversations. Model usage still depends on the model selected through OpenRouter; the plan price does not provide a token-rate estimate.
Scale
Scale costs EUR 399 per month or EUR 4,389 per year. It includes 6,000 AI conversations per month, 10 agents, 10 team members, API, Zapier and webhooks, advanced analytics and 500 MB of knowledge across up to 1,000 sources. The plan fee is flat, with no credit packs or per-resolution fee. If your expected traffic exceeds the included conversation allowance, the stated plan facts do not give an overage price; model that uncertainty before budgeting beyond the allowance.
EUR 29
A predictable plan fee still needs a usage check
Starter is EUR 29 per month and includes 500 AI conversations per month. Compare your expected AI conversations with the included allowance, then budget the selected model's usage separately. There is no per-resolution fee or credit pack, and the helpdesk inbox is included on every plan.
Total cost
What a monthly and yearly budget looks like
A chatbot cost calculator keeps four inputs separate: platform subscription, model calls, setup work and human handoff labor. For any team size, use this formula:
Monthly total = platform fee + model usage + setup cost allocated to the month + human handoff labor.
Yearly total = annual plan fee + yearly model usage + setup work + yearly human handoff labor.
Only the platform fee can be calculated from the plan prices below. Model rates, setup fees and labor rates depend on your choices and are not provided as fixed amounts here. Leave those cells blank until you have your selected model's current input and output rates and your own labor assumptions; a fabricated API total would not help you plan.
| Team size | Plan fit by included team members | Monthly platform fee | Annual platform fee |
|---|---|---|---|
| Solo | Starter includes two team members | EUR 29 | EUR 319 |
| Five people | Growth includes five team members | EUR 129 | EUR 1,419 |
| Ten people | Scale includes ten team members | EUR 399 | EUR 4,389 |
These are plan-fee totals, not full operating totals. They do not add model calls, setup or staff time. The Free plan includes one team member, but its 30 AI conversations are one-time rather than monthly, so it is not a monthly allowance to multiply across a year. Starter's annual fee is 11 times its monthly fee; the same yearly billing rule applies to Growth and Scale.
A plan fee is easier to budget when the included conversation allowance fits the work you expect. For a solo operator, Starter provides a recurring allowance and two team-member places. A five-person team can compare Growth's allowance and team capacity against the number of conversations that actually need AI replies. A ten-person team can make the same check against Scale. Team size alone does not determine whether the plan is worth paying for: include the time spent on setup and the human conversations still reaching the inbox. If you need a full-cost figure, add those inputs to the platform fee instead of treating the plan price as the whole bill.

Chatbot cost questions support teams ask
Use the billing unit and plan rules, not just the headline allowance, when estimating spend.
How do I estimate AI chatbot cost per month from conversations and tokens?
Estimate the number of model calls, input tokens per call and output tokens per call, then apply the selected model's current input and output rates. Longer prompts and answers, model choice and call volume can change the result. momo uses a model selected through OpenRouter, and the plan price does not supply those model rates.
What counts as a chatbot conversation for Botpress billing?
Botpress counts an exchange with at least two end-user messages in the billing month as a conversation. If one conversation spans two months, it counts in both months; separate anonymous sessions count separately. Botpress also counts AI-only and human-assisted conversations the same way.
Can Botpress conversation overages add to the monthly bill?
Botpress adds a pack of 100 conversations automatically when the workspace reaches 95% of quota. A pack costs $65, or $50 per pack for Team. Unused pack conversations expire at month end, while packs persist month-to-month until removed from billing settings.
How do DocsBot AI credits change with larger models or actions?
DocsBot credit use starts at 1x per message and may be higher for larger models and AI actions. Its stated monthly credit allowances are 100 on Free, 5,000 on Personal, 15,000 on Standard and 60,000 on Business. Advanced document parsing uses 2 AI credits per page and is included on Standard and Business.
Does chatbot cost include human handoffs in these plans?
The listed plan details do not state a per-handoff charge for the compared products, so do not infer one from the allowance alone. Human time can still affect your own operating cost. momo includes a helpdesk inbox on every plan, and teammates can take over any conversation live.
