AI costs range from free (ChatGPT free tier, Google Gemini) to enterprise-scale (00K+ for custom implementations). For mid-market businesses, the realistic range is $500-$10,000 per month for meaningful AI automation. Individual AI tools cost $20-200/month per user. Custom AI systems built for your specific workflows cost $3,000-10,000/month with a systems partner. The key question is not how much AI costs but how much your current manual processes cost you in time, errors, and missed opportunities.
