How much does AI cost for a small business?
Most small businesses spend $0 to $25 per person per month on AI. A solo owner can run on one $20 plan (ChatGPT Plus, Claude Pro or Google AI Pro), and a five-person team on a business plan pays about $100 to $125 a month. It pays off if each person saves more than about one hour a month.
The short version: AI is the cheapest hire you will ever make. The real cost is the time it takes to learn to use it well.

What businesses actually pay
Solo owner: $0 to $20 a month. One paid plan. Not three.
Team of 5: about $100 to $125 a month. One team plan for everyone, so chats stay private and are not used to train models.
Already on Google Workspace: you may already be paying for Gemini. Check before buying anything else.
Does it pay off
Do the math with your own numbers. If your time is worth $50 an hour, a $20 plan pays for itself the first time it saves you 24 minutes in a month.
The research says people save far more than that. Generative AI users in a St. Louis Fed survey reported saving 5.4% of their work hours, about 2.2 hours a week for a full-time worker (St. Louis Fed). In an MIT study, writing tasks took 40% less time with ChatGPT (MIT News).

The hidden cost
Tool stacking. Owners sign up for a writing AI, an image AI, a meeting AI and a scheduling AI, all $20 to $30 each, and use none of them well. One general assistant, used daily, beats five half-used subscriptions.

Is there free AI for small business?
Yes. ChatGPT, Claude, Gemini and Copilot all have free plans that handle emails, posts and summaries. You hit message limits on busy days, which is the signal to pay for one plan.
What are the most popular AI tools for business?
The general assistants: ChatGPT, Claude, Google Gemini and Microsoft Copilot. Then AI built into tools you already use, like Canva, Notion, HubSpot and Shopify. Start with one general assistant before paying for add-ons.
How much does custom AI for a business cost?
Custom builds by an agency usually run from a few thousand dollars up, plus monthly running costs. For most small businesses, a $20 plan plus connected apps does 80% of what a custom build would, so try that first.
