ROI of AI: How to justify the investment to the CFO
If you can't prove that AI saves hours or generates revenue, your project will be cut. Here is the spreadsheet.
Fabiano Brito
CEO & Founder
"Cool chatbot, but how much money does it bring?". If you stutter on that answer, your project is already dead. In lean times, innovation without ROI is a hobby.
But measuring Generative AI return is different from measuring traditional software. The gain is often invisible in the short term (efficiency) and explosive in the long term (new revenues).
The efficiency math (real cases)
To approve your budget, classify your project in these boxes. If it doesn't fit in any, don't do it.
| Use Case | Human Cost/month | AI Cost/month | Annual savings |
|---|---|---|---|
| Level 1 Support (5k tickets) | R$ 50,000 (5 JR) | R$ 5,000 (tokens) | R$ 540,000 |
| Contract review (100/month) | R$ 30,000 (2 PL) | R$ 800 (API) | R$ 350,400 |
| Lead qualification (SDR) | R$ 15,000 (3 interns) | R$ 1,200 (bot) | R$ 165,600 |
The two buckets the CFO approves
💰 Cost deflection
How much does a Level 1 call cost? R$ 10? If the bot handles 5,000/month, avoided human cost = R$ 50,000 and AI cost = R$ 5,000.
- Typical ROI
- 10× immediate
- Payback
- 1–2 months
- Risk
- Low
🚀 Revenue acceleration
If the sales rep takes 4h to reply to a lead, they've already cooled down. If AI qualifies and schedules the meeting in 2 minutes, conversion rises from 3% to 5%.
- Typical ROI
- 2× revenue
- Payback
- 3–6 months
- Risk
- Medium
The CFO doesn't care about "technology". They care about free cash flow. Speak their language.
