Short answer. Budget $50 to $75 per user per month for AI tools once you have identified specific use cases. Under that misses easy productivity wins. Above that requires specific ROI justification. Do not blanket-subscribe to every AI tool because the market is exciting. Match spend to actual usage.
The Baseline Budget
General LLM. $20 per user per month (ChatGPT Plus or Claude Pro).
Meeting notes tool. $10 to $25 per user per month (Fathom, Fireflies, Grain).
Total baseline. $30 to $45 per user per month.
For a 15-person team, that is $450 to $675 per month, or $5,400 to $8,100 per year. Trivial cost for the productivity gain if it is used.
When To Spend More
Specific use case with clear ROI. Sales team ready to adopt HubSpot AI. Marketing team ready to use Jasper for content production. Add the tool, measure the ROI, cut it if the numbers do not work.
Compliance or security requirements. Enterprise tiers for encryption, data retention, and audit trails. Cost premium is real. Justified for regulated industries.
Volume-based use. API access instead of consumer tiers when volume exceeds what the consumer tiers allow.
In every case, the increment above baseline needs a specific justification. Not 'this looks interesting.' Actual ROI math.
The Overspending Pattern
The most common mistake is subscription accumulation. ChatGPT and Claude and Gemini and Perplexity. Fathom and Fireflies. Jasper and Copy.ai and Writesonic. Midjourney and DALL-E and Stable Diffusion. Each seems useful. Together they cost hundreds of dollars a month per user and get used by nobody.
Audit AI subscriptions quarterly. Cancel anything not being actively used. The market moves fast. What was useful last quarter may be replaced by a better tool this quarter.
The Underspending Pattern
The opposite mistake: only using free tiers, missing the reliability and feature gap. Free ChatGPT vs Plus is a real productivity difference. Free meeting notes tools vs paid is a real difference in reliability.
For an SMB with information workers, the $30 to $45 per person per month baseline pays for itself in the first hour saved. Skipping it is penny-wise, pound-foolish.
Frequently Asked Questions
What should I spend on AI if I have 5 employees? +
Baseline: $150 to $225 per month total. That covers general LLM and meeting notes for everyone. Add specific tools as use cases emerge.
What if I have 50 employees? +
Baseline: $1,500 to $2,250 per month. May be worth enterprise agreements at that scale for negotiated pricing and administrative controls. Talk to the vendors.
Should I charge back AI costs to departments? +
For businesses with departmental P&L accountability, yes. Otherwise treat as general overhead. Chargebacks tend to reduce adoption. Weigh the accountability benefit against adoption cost.
What is a bad sign for AI ROI? +
Team is not using the tools you pay for. Check usage logs quarterly. Cancel or reassign licenses for unused seats. Subscription creep is real.
