How much do AI tools cost for a small business?

For a solo operator, a working AI stack costs roughly $20 to $70 a month. For a business of five people it is usually $150 to $350 a month. Those numbers assume off-the-shelf subscriptions, no developers and no custom build.

The sticker prices are not the interesting part. Almost every AI tool is priced per seat, per month, and advertised at its annual rate. Those three details are where budgets quietly go wrong, so this article covers the published prices first and the arithmetic second.

How much do small businesses actually spend on AI each month?

Most spend under $100 a month. In a survey of 942 US small business owners and financial decision-makers conducted in April 2026, Bluevine found that 28% spend $25 to $99 a month on AI tools and services, 16% spend $100 to $249, and only 10% spend $250 or more. A third spend nothing at all.

That is worth sitting with before you budget. The typical small business is not spending thousands. It is spending the price of a phone contract, and the ones getting the most out of AI are rarely the ones spending the most.

What do the main AI tools cost in 2026?

Here are the published list prices for the tools that come up most often in a small business context. All figures are US dollars, taken from each vendor's own pricing page and checked on 28 July 2026.

Why is the real bill higher than the sticker price?

Because four things sit between the advertised number and what leaves your account. None of them are hidden exactly, but all four are easy to miss when you are signing up in a hurry.

1. Per seat, not per business. Otter Pro at $8.33 a month reads as loose change. Across eight people it is $66.64 a month and $799.68 a year. Multiply every per-user price by your headcount before you compare anything.
2. Per seat versus per account. Zapier Professional is $19.99 a month for the whole account regardless of how many people touch it. Otter, ChatGPT Business, Claude Team and Copilot are all per person. Two tools with the same headline price can differ by 5x once your team is on them.
3. The licence underneath. Microsoft 365 Copilot Business is an add-on and requires a Microsoft 365 Business plan to sit on top of. If you do not already have one, the Copilot price is not your cost, it is part of your cost.
4. Usage caps you will hit. Zapier Professional includes 750 tasks a month. Otter Pro includes 1,200 recording minutes. Notion charges $10 per 1,000 credits for custom agents. Working out roughly what your volume looks like matters more than the plan name.

The same report notes that ChatGPT is now the most expensed application in the organisations it tracks, which tells you how much of this spend is happening on individual company cards rather than through anyone's budget.

The cheap AI tool is the one you cancel in week three. The expensive one is the subscription you keep paying for and stop opening.

Is it cheaper to pay monthly or annually?

Annually, by 15% to 50% depending on the tool. But the discount is only a saving if you were going to keep the tool for the full year, and roughly a third of new AI subscriptions get abandoned long before that.

The gaps, using the published prices above:

• Otter Pro: $16.99 to $8.33 a month. About $104 a year saved per person, the biggest discount on the list.
• Zapier Professional: $29.99 to $19.99 a month. $120 a year saved on the account.
• ChatGPT Business: $25 to $20 per user. $60 a year saved per person.
• Claude Pro: $20 to $17 a month, billed as $200 up front. $40 a year saved, but you pay the whole thing on day one.

Which AI tools are you already paying for?

Probably more than you think. A large amount of AI capability is now bundled into software you already have, which means the honest first step is auditing before buying.

• Google Workspace. Gemini is included in every plan at no extra cost, from Starter at $7 per user upwards. If you are on Workspace you already have an AI assistant in Gmail and Docs.
• Notion. Notion AI is included in the paid plans, so a business already paying $10 a seat for Plus does not need a separate writing tool for in-document drafting.
• Microsoft 365. This one goes the other way, and it is worth being blunt about it. Copilot is not included in a standard Microsoft 365 Business subscription. It is a paid add-on on top of a licence you are already buying.

Bundling also works in reverse. If you adopt one strong general assistant, several narrow subscriptions become redundant: standalone summarisers, most single-purpose writing tools, and often a second chat assistant kept out of habit. Cancelling two $15 tools funds a $30 one with no change to the budget.

What is a realistic monthly AI budget for a small business?

Three worked examples, using the annual rates from the table above. These are not recommendations, they are arithmetic, so you can see how the totals assemble.

How do you know if an AI subscription is paying for itself?

Divide the monthly cost by what an hour of your time is worth. That gives you the number of hours the tool has to save each month to break even, and it is almost always a smaller number than people expect.

At $80 an hour, a $20 tool breaks even at 15 minutes a month. A $231 stack across five people breaks even at under three hours a month for the whole team. If a tool cannot clear a bar that low after a fair trial, the problem is not the price, it is that the tool does not fit the work.

The failure mode is not overspending. It is paying $60 a month for four tools that each save twenty minutes in theory and nothing in practice, because nobody built them into a routine. [Steve — add a client example here: what their monthly AI bill looked like before and after, and which subscription got cut.]

If you would rather have the shortlist done for you, that is what an AI tools assessment is: a costed prescription of three to seven tools matched to your actual week, rather than a list you have to price out yourself. More on how I work is on the about page.
