What is the ROI of an AI voice agent in India?
The ROI of an AI voice agent is (extra revenue from calls + staff cost saved − calling cost) ÷ calling cost. For an Indian business supplementing or replacing an ₹18,000-a-month telecaller, Outpero's cost is talk time at ₹5 to ₹6.8 per connected minute plus ₹649 a month for a number, so the return depends mostly on how many leads get called quickly and convert. Prices exclude 18% GST.
The three inputs
- —Calling cost: connected minutes × tier rate, plus ₹649 for a dedicated number.
- —Staff cost saved or redeployed: salary hours no longer spent on first calls and reminders.
- —Extra revenue: conversions from leads that would otherwise have been called late or not at all.
A worked example with illustrative numbers
A coaching institute in Kota gets 600 enquiries a month from Meta and Google ads. Assume 70% connect and each call lasts 2.5 minutes on the Standard voice.
| Line | Calculation | Amount |
|---|---|---|
| Connected minutes | 600 × 70% × 2.5 | 1,050 |
| Talk time | 1,050 × ₹5 | ₹5,250 |
| Dedicated number | Monthly | ₹649 |
| Total calling cost | ₹5,899 | |
| Extra enrolments (assumed) | 3 × ₹25,000 fee | ₹75,000 |
On those assumptions, revenue alone returns about 12 times the calling cost, before counting any staff time saved. The assumptions are the important part: replace the enrolment count and fee with your own figures.
Why speed drives most of the return
The 2011 Harvard Business Review lead-response study found that firms contacting online leads within an hour were far more likely to qualify them than firms that waited longer. Outpero dials each new lead within 30 seconds, including evenings and weekends, which is where most of the extra conversions in a model like this come from.
When the ROI is weak
If you receive ten enquiries a week and the owner already calls each one within minutes, an AI agent adds little. The same is true when leads need long, consultative conversations that a script cannot carry. AI calling pays back most clearly where volume is high, response is slow, or calls happen outside office hours.
Inbound adds a second source of return
Calls to your business number that would otherwise ring out after hours, on Sundays or during lunch are picked up 24/7 by the AI employee, which handles the enquiry, qualifies the caller, books the appointment and logs the details. Each of those calls is billed on connected talk time, so capturing an enquiry that would otherwise have been missed costs a few rupees.

Follow-up questions
How quickly does an AI voice agent pay back?
+
There is no setup fee on Outpero, so there is nothing to recover up front; each month's spend is just talk time and the ₹649 number. Payback is therefore measured per month. If one extra sale or enrolment in a month is worth more than that month's calling bill, it has paid back.
