How this calculator works
| Metric | Formula |
|---|---|
| Human cost per call | (call minutes + after-call minutes) ÷ 60 ÷ occupancy × hourly cost |
| AI cost per call | call minutes × AI cost per minute |
| Cost with AI | AI-completed calls × AI cost + transferred calls × (1 AI minute + human cost) + platform fee |
Worked example
With these inputs:
- Currency: USD ($)
- Calls per month: 3,000
- Average call length: 4 min
- Voice AI cost per minute: 0.12
- Calls the AI completes without a person: 60%
- Human agent cost per paid hour: 15
- After-call work per call: 1 min
- Agent occupancy: 75%
- AI platform fee per month: 300
Monthly savings with voice AI: $1,692. 3,000 calls of 4 minutes cost about $5,000 a month with people only and $3,308 with a voice AI agent completing 60% of them.
| Cost per call — human / AI | $1.67 / $0.48 |
|---|---|
| Human-only cost per month | $5,000 |
| With voice AI — AI & platform | $1,308 |
| With voice AI — human agents | $2,000 |
| Agent hours freed per month | 200 |
| Yearly savings | $20,304 |

What makes up the per-minute price
| Component | Role |
|---|---|
| Speech-to-text | Transcribes what the caller says in real time |
| Language model | Understands intent and decides what to say or do |
| Text-to-speech | Speaks the reply in a natural voice |
| Telephony | Phone numbers and call minutes |
| Orchestration platform | Handles turn-taking, interruptions, transfers and integrations |
Getting it right
- Start with one or two call types that follow a clear script.
- Connect the agent to your calendar, CRM or order system so it can act, not just talk.
- Always offer a quick route to a person.
- Disclose that callers are speaking to an AI where required, and follow call-recording rules.
- Review transcripts weekly to improve prompts and answers.
