A small business can start using AI for about $20 a month, and a five-person team on a shared workspace plan typically lands around $100 to $125 a month. Costs rise only when you add automation tools, customer-support bots or heavy API usage. All prices below were checked on October 9, 2026.
If you are asking how much AI costs for a small business per month, the honest answer is “it depends on how many people use it and what you ask it to do.” The good news is that the main cost driver, an AI assistant seat, now sits at a predictable per-user price. This guide breaks down current list prices, three sample monthly budgets, and the extra costs that tend to surprise owners.
Quick answer: Budget roughly $20 to $25 per active user per month for a business-grade AI assistant. A solo owner can spend about $17 to $20, a five-person team about $100 to $125, and a ten-person team that adds automation and an AI support bot may land closer to $350 to $425 a month.
AI assistant prices per user in 2026
Most small businesses start with a team plan from one of four providers. These are the list prices (USD, before tax) at the time of writing.
| Option | Billed annually | Billed monthly | Good to know |
|---|---|---|---|
| Claude Pro (individual) | $17 per month | $20 per month | One person, no shared admin controls |
| Claude Team, Standard seat | $20 per seat | $25 per seat | For teams of 2 to 150, with central billing, SSO and no model training on your content by default |
| Claude Team, Premium seat | $100 per seat | $125 per seat | 5x the usage of a Standard seat, aimed at daily heavy users |
| ChatGPT Business (Standard seat) | $20 per user | $25 per user | Minimum of 2 seats; price was lowered on April 2, 2026 |
| Google Workspace Business Standard (Gemini included) | about $14 per user | about $16.80 per user | Includes the full Workspace suite; Business Starter costs less but has only limited Gemini in the apps |
| Microsoft 365 Copilot Business (add-on) | $21 per user | Annual commitment | Needs an existing Microsoft 365 Business plan; for organizations up to 300 users |

Google’s per-user Workspace prices come from its 2025 price announcement as reported by the press, so confirm the current figure at checkout.

Three sample monthly AI budgets
These examples use the list prices above. They are illustrative estimates, not quotes, and they exclude tax and any setup work.
| Business profile | What is included | Estimated monthly cost |
|---|---|---|
| Solo owner | One paid assistant plan, plus an entry-level automation plan | About $37 to $50 |
| 5-person team | Five Standard seats on a shared team plan | About $100 (annual) to $125 (monthly) |
| 10-person team with automation and support | Ten Standard seats, a 2,000-task automation plan, and about 100 AI-resolved support conversations | About $350 to $425, before help desk seats |
The math behind the last row: ten seats cost $200 to $250, a 2,000-task automation tier costs roughly $49 to $74, and 100 AI-resolved conversations at $0.99 each add about $99.
Costs beyond the chat assistant
Workflow automation
Automation tools charge by the task, which means every action step in a workflow counts. Zapier advertises its Professional plan from $19.99 a month on annual billing, or $29.99 billed monthly, for 750 tasks. A workflow with four steps that runs 100 times a day can burn through thousands of tasks, so estimate your volume before choosing a tier.
AI customer support
Support bots are often priced per outcome rather than per seat. Intercom’s Fin agent, for example, charges 99 cents per resolved conversation, according to Stripe’s case study on Fin’s pricing. That is cheap at low volume, but you may also pay for help desk seats underneath it, and your bill grows as the bot succeeds.
Building your own tools with an API
If a developer builds a custom assistant, you pay per token instead of per seat. On the Claude pricing page, Sonnet 5.5 is listed at $2 per million input tokens and $10 per million output tokens. As an illustration, 1,000 chats a month with about 2,000 input tokens and 500 output tokens each would use 2 million input tokens ($4) and 0.5 million output tokens ($5), roughly $9 in model usage. Development time, hosting and monitoring are extra.
Hidden costs to plan for
- Usage limits and overages. Seat plans include a fixed amount of usage. On Claude Team plans, organizations can switch on extra usage that is billed beyond seat limits, so heavy users can raise the bill.
- Premium seats. One Premium seat costs as much as five Standard seats, so assign them only to people who hit limits regularly.
- Overlapping subscriptions. It is easy to end up paying for two or three assistants that do much of the same work. Pick one primary tool and review the others after a month.
- Training and process time. The cheapest seat is wasted if nobody learns how to use it. Set aside a few hours for shared prompts and workflows.
- Taxes and currency. Prices shown are in US dollars before tax, and regional prices can differ.
How to keep your AI bill low
- Start with the free tiers and one or two paid seats for the people who will use AI daily.
- Choose annual billing once you are sure of the tool. On the plans above it saves about $5 per seat each month.
- Use the AI that comes with software you already pay for, such as Workspace or Microsoft 365, before adding another subscription.
- Add automation and support tools one at a time, and measure the hours or tickets they actually save.
- Review usage after 60 to 90 days and downgrade or reassign unused seats.
Plans, limits and promotions change often. Always confirm the final price on the provider’s own pricing page before you subscribe.
Frequently asked questions
Can a small business use AI for free?
Yes, for testing. Free plans exist, for example Claude’s Free tier at $0, but they come with tighter usage limits. Team plans add shared billing, admin controls and, on Claude Team, no model training on your content by default.
Is ChatGPT or Claude cheaper for a small business?
Their standard business seats are priced the same on the official pages: $20 per user per month on annual billing and $25 on monthly billing. The better choice depends on the features and usage limits your team needs, not the sticker price.
Do I pay per user or per use?
Both models exist. Assistant plans are usually per seat, automation tools charge per task, some support bots charge per resolved conversation, and APIs charge per token.
How much should I budget to get started?
A practical starting point is $20 to $25 per active user per month, plus a small buffer for one automation tool if you need it. Expand only after you see which tasks the team actually hands to AI.
