Monthly cost of these contacts, from your numbers only.
| Scenario | Per month | Per year | Vs human agents only, per month |

These results are only as good as the inputs. They use only the numbers you entered, and they leave out setup, integration and fixed costs.
The formula in plain words
- Human agents only: contacts per month × minutes per contact × human agent cost per minute.
- Voice AI only: contacts per month × minutes per contact × voice AI cost per minute.
- Human agents + A2A: the share you enter moves to direct agent-to-agent, one A2A task per contact, at your cost per A2A task. The remaining contacts stay with human agents at the same minutes and cost per minute.
- Voice AI + A2A: the same split, with voice AI handling the remaining contacts.
- Per year is per month × 12. The last column is each scenario's monthly cost minus the human agents only cost, so a negative number is a saving.
With your numbers
Limitations
- Results are only as good as the inputs. The calculator has no numbers of its own, and Emissar doesn't publish industry averages for these costs.
- It assumes a contact that moves to A2A needs no human or voice AI minutes at all, and that one contact becomes one A2A task. Real handoffs can take several tasks, or still need a person.
- It compares running costs only. Building or buying an A2A endpoint, integration work, contracts and minimum fees aren't included.
- The share that moves to A2A depends on how many of the agents contacting you can speak A2A, which you have to estimate.
Privacy
