AI Automation ROI
How to Calculate Your ROI
The simplest ROI formula for AI automation: take the number of hours saved per week, multiply by your team's hourly rate, and compare to the monthly tool cost. For example, a chatbot that handles 40 customer inquiries per week at 5 minutes each saves 13 hours per month. At $30/hour, that is $400/month in time savings. If the chatbot costs $50/month, your ROI is 8x.
But time savings are only part of the picture. Factor in: revenue from leads you would have missed (after-hours inquiries), faster response times improving conversion rates, fewer errors reducing rework, and the value of your team focusing on higher-impact activities.
A dental practice that automates appointment reminders, for instance, typically reduces no-shows by 30 to 50%. If each missed appointment costs $200 in lost revenue and you have 10 no-shows per month, that automation recovers $600 to $1,000/month.
Where to Start Without Overspending
Week 1: Use ChatGPT (free) to draft emails, create social posts, and answer business questions. Cost: $0. Track how much time it saves.
Week 2 to 4: Set up one workflow automation using Zapier or Make free tier. Automate your highest-frequency manual task (lead follow-up, appointment reminders, or data entry). Cost: $0.
Month 2: If the free tools are proving their value, upgrade to paid tiers for higher limits. Add a second automation. Budget: $50 to $150/month.
Month 3 and beyond: Based on measured ROI, expand to AI chatbots, advanced CRM features, or custom AI agents. Scale spending in proportion to proven returns.
