Real cost of AI for a 10-person business
Exact monthly spend, hours saved, and ROI from a real 10-person team over 6 months.
The actual monthly bill: $199 for a 10-person team
We tracked AI tool spending across a real 10-person mixed team (2 developers, 3 marketers, 2 salespeople, 1 designer, 1 project manager, 1 CEO) for 6 months. Total average monthly spend: $199. Breakdown: ChatGPT Plus ×3 ($60) + Notion AI ×4 ($64) + Canva Pro AI ($15) + GitHub Copilot ×2 ($38) + Grammarly Business ×2 ($22). MailerLite (free plan) and Perplexity (free) added no cost.
Hours saved: 12.5h per week, not per person
The team reported saving an estimated 12.5 hours per week collectively — not per person. That breaks down as: content creation (4h saved), email drafting and summaries (3h), code review and completion (3.5h), meeting notes (2h). At an average team billing rate of $25/hour, that represents $312/week or $1,353/month in recovered time.
Best ROI: Notion AI and GitHub Copilot
The highest ROI tools were Notion AI ($16/user/month) and GitHub Copilot ($19/user/month). Notion AI eliminated almost all manual meeting notes and simplified wiki management. GitHub Copilot reduced developer time on boilerplate by an estimated 35%, which at $38/month for 2 seats is easily justified. ChatGPT Plus had broad use but also the most "play" use, reducing its measurable ROI.
Surprise: the CEO saved the most time
Counter-intuitively, the team member who saved the most time was the CEO. Using ChatGPT Plus for email drafts, summaries, investor update templates, and weekly planning saved an estimated 4h/week. At executive hourly value, this represented the highest individual ROI on the team.
The hidden cost: onboarding and prompt quality
The team spent approximately 8 hours in the first month learning prompting best practices. Tools like Notion AI and Canva AI required almost no training (UI-driven). ChatGPT Plus and Claude required 2-3h of learning to use effectively. This hidden onboarding cost is rarely included in ROI calculations but matters, especially for non-technical team members.
Methodology
Case study with a single 10-person SaaS company (anonymised) tracked from November 2025 to April 2026. Time savings are self-reported by team members in a weekly 5-minute survey. Financial values use a conservative $25/hour blended rate across all roles.
