How do I compare AI calling results with human telecallers?
Compare AI calling and human telecallers on the same lead source over the same weeks, using four numbers: time to first call, contact rate, qualified leads per hundred leads, and cost per qualified lead. Split leads randomly rather than giving one side the better list. Expect people to win on complex, emotional conversations and AI to win on speed, after-hours coverage and cost per call.
Design a fair test
- 01Pick one lead source with steady volume, such as Meta lead ads or a property portal.
- 02Split incoming leads randomly — odd and even lead IDs work — so neither side gets the warmer leads.
- 03Agree one written definition of ‘qualified’ before starting.
- 04Run for at least two to four weeks, avoiding festival weeks where possible.
- 05Track every lead to the same final outcome: visit, demo, admission, sale.
What to measure
| Metric | Why it matters |
|---|---|
| Time to first call | The biggest single driver of contact rate |
| Contact rate | How many leads were actually spoken to |
| Qualified per 100 leads | Quality of the conversation and questions |
| Bookings per 100 leads | Real business outcome |
| Cost per qualified lead | What each good lead costs to find |
| Leads never called | Coverage gaps, often hidden in human teams |
The cost side
A human telecaller in India costs roughly ₹15,000–₹25,000 a month; ₹18,000 is a fair reference. That buys one shift and one call at a time. The same ₹18,000 buys about 3,600 connected minutes on Outpero's Standard voice at ₹5 a minute, spread across as many concurrent calls as you need. Include managers' time, training and attrition on the human side, and the phone number on both.
Where people still win
- —Long, consultative conversations — a ₹2 crore property, a complex insurance claim.
- —Negotiation and closing.
- —Callers who are upset and need someone with authority.
- —Relationships with repeat B2B buyers who expect a known voice.
Read the results honestly
If the AI side shows more contacts but fewer bookings, the script or the handover is the problem, not the idea. If telecallers win on bookings but only reached half the leads, the real comparison is what happens when both work together. Share the raw numbers with the team, not just the conclusion.
Many teams end up with a split rather than a winner: the AI agent calls every lead within seconds and qualifies, and telecallers spend their day on the qualified ones. Outpero's call summaries and custom fields make that handover clean.
