Cost per Qualified Loan Lead: AI Calling vs a Human Team

Compare a human caller and an AI caller on salary against subscription and the AI wins by a mile and tells you nothing. The number a broker cares about is cost per qualified lead: what you spent on calling, divided by the leads that passed your screen. This article gives you the formula, the inputs, and the figures we can stand behind. Every result is yours to measure. We don't publish one for you.

Key Takeaways

• Cost per qualified lead is total calling cost divided by the number of leads that passed your screen.
• Topcalls AI calls to US numbers (Zone 1) cost $0.25/min, billed by the second, with no seat fees for AI calling.
• A fully loaded human SDR works out to an estimated $3 to $5 per minute of real talk time, per our human vs AI cost spec.
• A US sales representative's median base pay is $66,780 a year, per the Bureau of Labor Statistics (May 2024).
• Your pass rate and contact rate move the answer more than the per-minute price does.

1. How do you calculate cost per qualified lead?

Add everything you spend on calling in a period, then divide by the number of leads that passed your screen in the same period. In symbols: cost per qualified lead = (calling cost + software cost + management cost) / qualified leads. The qualified count comes from your CRM dispositions, not from a guess.

Two ratios sit inside that fraction. The contact rate is the share of leads you actually reach, and the pass rate is the share of reached leads that meet your lenders' criteria. Improve either one and the cost per qualified lead falls without changing a single price.

2. What does an AI call cost?

Topcalls charges $0.25/min for an AI call to a US number (Zone 1), billed by the second: $0.15 for the AI plus $0.10 for the phone line. The price covers the AI, the phone line for the destination's zone, recording, transcription and analytics, so there's no separate transcription bill. Check the exact rate for the country you call on the pricing page.

Say a screening call runs four minutes. At the Zone 1 rate of $0.25/min, a four-minute call to a US number costs $1.00. That's arithmetic on an assumption, not a result: your average call length is whatever your transcripts show, and calls that end at the first disqualifier are shorter.

3. What does a human caller cost?

Start from the wage, then load it. The Bureau of Labor Statistics puts the median base pay for a US sales representative near $66,780 a year (May 2024). Benefits, payroll taxes, software and management commonly add 25 to 40 percent on top. Then divide by talk time, not by hours worked, because a caller spends much of the day researching, logging notes and dialing numbers that ring out. That's how a loaded rep lands at an estimated $3 to $5 per minute of live conversation. It's an estimate, and your own payroll and call logs will give you a better one.

The full working is on the human vs AI call cost spec.

4. How do the two compare side by side?

Fill the table with your own numbers before you decide anything. The row that surprises most brokers is the third. Every hour a good lead waits is money you've already spent on that lead.

5. Where does the human team still win?

On complicated files. A stacked MCA, an unusual collateral package, or an owner who needs coaching through paperwork is worth a skilled broker's per-minute cost. The sensible split is AI on the repetitive top of the funnel, people on the files that reward judgment.

It also helps to remember that cost per qualified lead isn't the whole story. A cheap qualified lead that never closes isn't cheap. Track cost per funded deal too once you have enough volume to see it.

6. How do you run the comparison yourself?

Pick a week of leads and split them in two groups of the same kind. Call one group the way you do today and the other with the AI. Record spend, contacts, passes and, later, funded deals for each. Then plug your numbers into the formula. For a quick first pass, use the ROI calculator.
