Use the AI Receptionist Cost Calculator
Enter your own figures below. The results table and chart update as you type. The default scenario is pre-loaded so you can see the method before you change anything.
Default results
| Result | Value |
|---|---|
| Human hours per month | 44.33 |
| Human monthly cost | $1,152.67 |
| AI route monthly cost | $1,019.4 |
| Net monthly saving | $133.27 |
How to use this calculator
- Start with the default scenario. Read the results table and the chart so you understand what each output means.
- Replace the default inputs with your own figures. Use loaded costs, not base salaries, wherever the input asks for cost.
- Change one input at a time. This shows which assumption moves the result most and where your evidence is weakest.
- Run a conservative case. Cut the share or adoption input by 20% and see whether the project still makes sense.
- Save the inputs and the results table. That becomes the first draft of your internal business case.
How we calculate this
Every output comes from the formulas below. Nothing is drawn from a survey, a client result or a third-party benchmark. The figures are model estimates based on the inputs you supply.
| Output | Formula | What it means |
|---|---|---|
| Human hours | calls x minutes / 60 | Total staff hours needed without automation. |
| Human monthly cost | human hours x loaded hourly cost | Full cost of covering the same call volume manually. |
| AI monthly cost | setup/12 + monthly fee + (human hours x (1-share) x loaded hourly cost) | Setup amortised over 12 months plus subscription plus residual human handling. |
| Net monthly saving | human monthly cost - AI monthly cost | Positive saving means the AI route is cheaper in this model. |
Worked example
A clinic takes 700 inbound calls a month at 3.8 minutes each. At a $26 loaded hourly cost, human cover costs $1,143 a month. With 60% handled by an AI voice agent, $2,500 setup and $350 monthly fee, the AI route costs $807 a month, giving a $336 monthly saving.
| Input | Value |
|---|---|
| calls | 700 |
| minutes | 3.8 |
| wage | 26 |
| share | 60 |
| setup | 2,500 |
| monthly | 350 |
Assumptions and limits
This model is deliberately narrow. It values time and direct cost only. It does not price quality improvement, customer satisfaction, risk reduction or revenue lift, because those need evidence from your own operation.
Adoption is the most common source of error. A system that works in a pilot rarely hits its full share on day one. For planning, assume a ramp and test the conservative case.
The model also ignores integration difficulty. Two systems with the same name can differ enormously in effort. List each integration and its owner before you commit budget.
Finally, the figures are not a quote. They are a planning tool. Use them to frame a conversation, then get a scoped proposal based on your actual systems and workflows.
Questions about AI Receptionist Cost Calculator
How does the calculator compare cost?
It compares the full human cost of covering a call volume with the combined cost of an AI voice agent and residual human handling.
This is fairer than comparing a wage against a subscription, because an AI system rarely handles 100% of calls. Someone still handles complex or sensitive conversations.
What share can an AI receptionist handle?
Handling share depends on call type, script quality and escalation design. Routine bookings and FAQs often automate well; complex cases need a human.
A sensible planning range is 40% to 70% for mixed call traffic. Use the lower end if most calls involve judgment, account changes or upset callers.
Why is setup amortised over 12 months?
Spreading setup over a year makes the monthly comparison fair, because a one-off build cost would otherwise distort a single month.
If you expect the system to run for several years, amortising over a longer period is reasonable. For conservative budgeting, keep the 12-month view.
Does this include quality risk?
No. The model compares cost only. It does not price the risk of a poor caller experience.
Before deciding, test the voice agent on real calls, measure transfer rates and caller satisfaction, and keep a clear human escalation path.
When is a human receptionist still better?
A human is better when calls need empathy, complex judgment, account authority or a personal relationship the business depends on.
Cost is not the only criterion. If most calls are high value or sensitive, the model will show a small saving, and that is the correct signal to investigate rather than to automate aggressively.
