Most dealerships size a lead order on hope. The honest way to size it is to work backward from the deal target, the real close rate, and the team's real working capacity. Here is that math, using 8 to 12 percent and $7K to $10K.
Most dealerships ask the lead vendor the wrong question first. They ask "how many leads can you send me" before they have worked out how many leads their team can actually work, what close rate those leads need to hit, and how many deals they need to hit to justify the spend. The result is a dealership that buys a lead volume built on hope, then blames the leads when the math was never there.
The honest way to size a monthly lead order is to work backward from three numbers: your monthly unit goal, your team's real close rate, and your team's real working capacity. Let's walk through how that math works using the numbers we actually see across our dealer partners.
Start with the deal target, not the lead count
Say a dealership wants to add 20 subprime deals a month from a new lead source. That is the target the dealer principal actually cares about, so it is where the math should start. Working backward from deals, not forward from a lead count, is the only way to avoid buying a volume the team cannot close.
If your target is 20 deals and your realistic close rate on subprime leads from a credit-screened, phone-verified source is 10 percent, you need roughly 200 leads to land 20 deals. That 10 percent sits in the 8 to 12 percent range we see across our partners, and it is the honest place to plan around. A dealership that plans around a 20 percent close rate because one good month hit it is planning on a number the team will not reproduce.
Match the volume to your BDC's real capacity
Lead count is only useful if your team can actually work each lead inside the first hour. The single biggest close rate killer we see is not lead quality. It is slow follow-up, because a subprime lead goes cold fast. A buyer who applied for financing online is also applying with two other dealerships. The first dealership to reach them, with a real answer, usually wins.
So size the order to capacity, not to ego. If your BDC can responsibly work 150 leads a month at the right speed, buying 300 does not give you twice the deals. It cuts your close rate on both halves, because each lead gets a worse call. A smaller, fully-worked order at 10 to 12 percent close beats a larger, half-worked order at 4 percent every time.
Run the gross-profit math to make the spend make sense
Once the lead volume matches a deal target and a workable close rate, run the gross math. At an average gross per subprime deal of $7,000 to $10,000, which is what our partners report, 20 deals a month produces roughly $140,000 to $200,000 in gross profit from that one source. From there, the cost of the leads is a line item, not the whole conversation.
This is why asking "how much per lead" too early is a mistake. The cost per lead only matters once you know the close rate and the gross per deal that lead produces. A $35 lead that closes at 10 percent into a $9,000 gross is a vastly better buy than a $15 lead that closes at 3 percent into the same gross, even though the $15 lead looks cheaper on a cost-per-lead report.
What actually happens when a dealership overbuys leads
When a dealership buys more leads than its team can work, three things happen in sequence. The first call moves later. The close rate drops. The dealer principal blames the lead quality, because the report shows leads bought up and deals flat. The real cause was a capacity mismatch the lead vendor warned about before the order went live.
We see this enough that we will tell a dealer principal to buy fewer leads if the math says so. A lead vendor that only sells more is not a partner, it is a billing relationship. The dealerships that win on subprime match the order to the team, then grow the order as the close rate and the capacity prove out.
Plan for the replacement guarantee, not against it
Subprime leads are not perfect, because subprime buyers are not perfect. A credit-screened, phone-verified lead can still fall out: a buyer changes their mind, a lender declines, an income doc does not verify. That is not a lead vendor problem. It is the shape of subprime. Which is why a replacement guarantee exists.
Our leads are backed by a 48-hour replacement guarantee. If a lead does not meet the agreed standard, it is replaced inside 48 hours. The right way to size your order is to plan as if a small percentage will be replaced, and budget your team's attention on the leads that are worked, not on arguing about the one that fell out. Dealerships that use the guarantee cleanly, replacing the bad lead quickly and moving on, close a higher percentage of the good ones.
The honest answer to "how many leads do I need"
The answer is: enough leads to hit your deal target at your real close rate, sized to the number of leads your BDC can actually work inside the first hour, and modeled against a gross per deal of $7,000 to $10,000. For the dealerships we work with, that usually lands between 150 and 400 leads a month for a single store running a focused subprime pod, and more for a multi-rooftop group running per-store funnels.

Frequently Asked Questions
Q: What close rate should I use to plan my lead volume? A: Plan around 8 to 12 percent, which is what credit-screened, phone-verified subprime leads produce across our dealer partners. Planning around a higher one-time number sets the team up to miss.
Q: What if my team cannot work the leads fast enough? A: Buy fewer leads. A smaller order that gets a same-hour first call will outclose a larger order that does not. Lead volume should match your BDC's real capacity.
Q: What gross per deal should I model? A: Our partners report average gross of $7,000 to $10,000 on subprime deals. Model your gross profit against that range, then size the lead spend as a line item underneath it.
Q: How does the replacement guarantee affect my order? A: It works as a safety net. Plan a small percentage of leads to be replaced, replace the bad ones inside 48 hours, and focus your team's attention on the leads that are worked.
Q: Can one store absorb 400 leads a month? A: Only with a BDC sized for it. Single stores usually land closer to 150 to 300 leads a month. A multi-rooftop group spreads that volume across stores with per-store funnels.
