Why ROI Calculation Matters
Before investing in AI automation, you need to know: will this actually pay off? The good news is that AI automation ROI is measurable and typically strong. The average ROI across our clients is 340% in the first year.
The ROI Formula
ROI = (Gains from Automation - Cost of Automation) / Cost of Automation x 100
Simple enough, but the challenge is quantifying “gains.” Here is how to do it properly.
Identifying Gains
1. Time Savings
Calculate hours saved per week on automated tasks:
- Hours spent on task x hourly cost of employee = weekly savings
- Example: 10 hours/week x 35 EUR/hour = 350 EUR/week = 1,520 EUR/month
2. Revenue Increase
New revenue from faster lead response, 24/7 availability, or better conversion:
- Additional leads captured x conversion rate x average deal value
- Example: 30 extra leads x 15% conversion x 800 EUR = 3,600 EUR/month
3. Cost Reduction
Reduced support costs, fewer no-shows, less manual processing:
- Before cost - After cost = monthly savings
- Example: Support costs drop from 5,000 to 2,000 EUR = 3,000 EUR/month saved
4. Error Reduction
Fewer mistakes in data entry, scheduling, or communication:
- Number of errors x cost per error = monthly savings from accuracy
Identifying Costs
One-time Costs
- Development/setup: 3,000 to 15,000 EUR
- Integration work: 1,000 to 5,000 EUR
- Training and onboarding: 500 to 2,000 EUR
Ongoing Costs
- AI API usage: 50 to 300 EUR/month
- Hosting: 30 to 150 EUR/month
- Maintenance: 200 to 500 EUR/month
- Platform fees: Variable
Example Calculation
A dental clinic invests in AI appointment booking:
Costs:
- Setup: 6,000 EUR
- Monthly running: 500 EUR
- Year 1 total: 12,000 EUR
Gains:
- 15 extra appointments/month from captured calls: 15 x 120 EUR = 1,800 EUR/month
- Reduced no-shows (saving 8 slots/month): 8 x 120 EUR = 960 EUR/month
- Receptionist time saved (10 hrs/week): 10 x 25 EUR x 4.3 = 1,075 EUR/month
- Total monthly gain: 3,835 EUR
- Year 1 gain: 46,020 EUR
Year 1 ROI: (46,020 - 12,000) / 12,000 x 100 = 284%
Benchmarks by Use Case
| Use Case | Typical Year 1 ROI |

Tips for Accurate Calculation
- Be conservative: Use lower estimates for gains
- Include hidden costs: Staff time for management, training
- Track baseline first: Measure current performance before implementing AI
- Review quarterly: Adjust calculations as real data comes in
