Every month you sign invoices to Cars.com, CarGurus, Autotrader, and the rest. And every month the same question goes unanswered. What is a third-party lead actually costing you?
The real numbers are easier to find than you would think. Cars.com and CarGurus are publicly traded companies, so they report the average amount dealers pay them each quarter. Your invoices and your CRM supply the rest.
This post uses those filings to show three things:
- What dealers really pay Cars.com and CarGurus, drawn from the companies’ own reported per-dealer revenue.
- Why cost per lead flatters the marketplace and hides your true cost per sale.
- What the dealers we work with actually spend, calculated from their invoices and CRM.
Why Cost Per Lead Makes a Platform Look Cheap
Cost per lead is what a platform charges you per shopper inquiry, divided so each contact carries a price tag. The trouble is that not all inquiries are worth the same, and cost per lead treats them as if they were.
On a shared marketplace, the same shopper fires off inquiries to several dealers from a single listing page, so the lead you paid for is often one three competitors paid for too. And the leads arrive mixed, at every level of intent:
- Buyers ready to purchase this week
- Early browsers who are months from a decision
- Duplicates and bad phone numbers
- Tire-kickers who never pick up
A platform counts all of these the same way when it quotes you a low cost per lead. In one account we analysed over a single month, an automated feed delivered about 1,380 leads and generated zero attributed sales. Every inquiry carried the same low cost per lead, and none of them resulted in a sale.
It gets worse inside a single platform. In that same account and month, one CarGurus sub-channel converted at 9.2%, while another CarGurus sub-channel turned 76 leads into zero sales, at a 71% bad-lead rate.
A blended cost per lead would average the two together and hide the dead one completely.
That is how a $50 lead sounds cheap, right up until you count how many of them it takes to make one sale.
How Much Do Dealers Pay Cars.com and CarGurus?
Dealer listing site fees are easier to pin down than most owners expect. Because Cars.com and CarGurus are public companies, they report, on the record and in audited filings, roughly what the average dealer pays them.
Cars.com reports a figure it calls Monthly Average Revenue Per Dealer, or ARPD. For the second quarter of 2026 it was $2,500 a month, up 3% from $2,435 a year earlier, which puts the average Cars.com dealer at about $30,000 a year for subscription products. It excludes digital advertising and the company’s DealerClub wholesale product, so the all-in figure for a dealer buying those is higher.
CarGurus reports a similar figure every quarter, which it calls Quarterly Average Revenue per Subscribing Dealer, or QARSD. For the second quarter of 2026, US QARSD was $8,134, up 8% from a year earlier. That is a quarterly number, so dividing by three to compare it with Cars.com puts it at around $2,711 per month for the average US CarGurus dealer.
| Cars.com | CarGurus (US) | |
|---|---|---|
| What they report | Monthly Average Revenue Per Dealer (ARPD) | Quarterly Average Revenue per Subscribing Dealer (QARSD) |
| Latest figure | $2,500 per month | $8,134 per quarter |
| Monthly equivalent | $2,500 | ~$2,711 ($8,134 ÷ 3) |
| Annualised | ~$30,000 | ~$32,500 |
| Year-on-year change | +3% (from $2,435) | +8% |
| Dealer base behind the average | 19,343 dealer customers | 26,151 US paying dealers |
| What the metric excludes | Digital advertising and the DealerClub wholesale product | Non-US dealers; the figure covers paying subscribers only |
| Why they are not interchangeable | One is per dealer customer, the other per paying subscriber. One is monthly, the other quarterly. Cars.com’s is total company; CarGurus’ is US only. Both are averages across tens of thousands of dealers of very different sizes, so they are a benchmark, not a target. | |
Those averages tell you what a platform costs. They do not tell you what it is worth. For that you need the other half of the equation, which is the sales each platform actually produced, and that turns spend into cost per sale.
What Dealers Reported Paying CarGurus in 2020
The figures below are five years old and predate several rounds of price increases, so read them for the spread rather than the absolute numbers. What still holds is the range: cost per listing view varied more than fourfold between markets, and monthly invoices varied more than sevenfold, for the same product.
| Market | Monthly invoice (2020) | Cost per listing view |
|---|---|---|
| Dallas–Fort Worth | $468 | $0.07 |
| Boston (Manchester) | $1,140 | $0.11 |
| Philadelphia | $2,550 | $0.18 |
| Boise | $795 | $0.25 |
| Baton Rouge | $3,416 | $0.29 |
| Columbia–Jefferson City | $2,020 | $0.29 |
The durable insight is not the invoice amounts. It is that a dealer in one market paid four times as much per listing view as a dealer in another, for identical placement. That gap is the reason your own cost per sale, not a published average, is the number that matters.
How to Calculate Your True Cost Per Sale
Cost per sale is total platform spend divided by the sales you can attribute to that platform. Getting it right depends less on the division than on two attribution rules you apply to every channel, your own website included.
The numbers below are an illustrative example, not client data. Two platforms cost the same for the quarter and return very different value.
| Platform A | Platform B | |
|---|---|---|
| Quarterly spend | $9,000 | $9,000 |
| Leads | 180 | 200 |
| Cost per lead | $50 | $45 |
| Attributed sales | 6 | 3 |
| Cost per sale | $1,500 | $3,000 |
On a cost-per-lead basis, Platform B even looks like the better buy at $45. On a cost-per-sale basis, it costs twice as much.
The number only means something if your attribution is honest, so set two rules first and apply them to every channel.
1. Credit the First Source, Not the Last Click
Give the sale to the platform where the buyer first entered your funnel, not the last click before they signed. In practice this lives in the lead-source field on the customer record in your CRM, whether that is VinSolutions, Elead, or DealerSocket.
The trap is that a later touch can overwrite that field, so a buyer who first arrived through Autotrader in month one gets recoded to “website” or “walk-in” by the time the deal closes, and the platform that actually created the opportunity disappears from your reporting.
Check how your CRM handles a second touch on an existing record, lock the original source so it cannot be rewritten, and audit a sample of closed deals against the raw lead feeds to confirm the field held.
2. Use a Trailing 90-Day Attribution Window
Someone who first showed up in month one and bought in month three still counts against the channel that brought them in. When a buyer crosses the boundary, credit the original source and record the full time to close, so your cost per sale reflects real buying behaviour rather than an artificially short window. Ninety days fits how used-car shoppers actually move.
There is no universal cost-per-sale benchmark, and any figure that claims to be one should make you suspicious, because the honest number depends entirely on your margins.
What matters is your own gross per sale. If a channel costs more per sale than the average front-end gross it brings in, it is losing you money on every deal, no matter how the per-lead price looks.
What Cost Per Sale Looks Like in a Real Dealer’s Account
The numbers below come from one two-rooftop used-car group we work with, comparing what each store spent in a single month against the sales attributed to each platform that month. One month at one group is an illustration of the variance, not a benchmark for your market.
| Platform | Rooftop A cost per sale | Rooftop B cost per sale |
|---|---|---|
| CarGurus | ~$572 | ~$1,261 |
| Autotrader | ~$570 | Spend, but no attributed sales |
| Cars.com | ~$1,625 | ~$654 |
| Capital One | ~$450 | ~$1,500 |
The same platform can cost radically different amounts at two stores owned by the same owner. CarGurus came to about $572 per sale at one rooftop and about $1,261 at the other, more than double, for the same platform.
What drives that gap is market density, inventory, and how each desk handles and logs its leads, not the platform itself. Run one blended number across both stores and you would never see it.
Which platform wins also flips from store to store, so there is no such thing as a best channel for the group, only a best channel for each rooftop. Capital One was the cheapest way to sell a car at one store and among the most expensive at the other. Cars.com ran the opposite way. One platform even generated sales at one rooftop and none at the other, on comparable spend.
A per-lead price would have flattened all of this into a single misleading average. Only cost per sale, run per platform and per rooftop, tells an owner where the money is actually working.
How to Benchmark Your Dealership’s Third-Party Lead Costs
Once you can run cost per sale for one platform, the filings provide a benchmark, and your own invoices show the differences that matter.
Benchmark Your Invoice Against the Filings
Pay well above the ~$2,500 Cars.com or ~$2,711 CarGurus monthly average and you are on a premium tier. Worth it if the cost per sale earns it, worth a hard question if it does not.
In one dealer group we work with, a single CarGurus rooftop billed about $14,866 in a month, roughly five and a half times the reported average. The second rooftop billed about $10,090, roughly three and a half times. A number that far above the benchmark is not automatically wrong, but it has to be justified by cost per sale.
Compare Cost Per Sale Across Platforms
Most dealers run several marketplaces at once, and cost per sale almost always shows one or two carrying the return while the rest ride along on the budget. Finding those is the whole point.
In the account we analysed, three channels out of more than seven — CarGurus, the dealer’s own website, and Capital One — produced the large majority of traceable sales in a single month. The rest generated little for comparable spend.
Some dealers work it out on their own. On the DealerRefresh forum in June 2019, one dealer described running the numbers on every lead source before touching costs, and found Autotrader was costing about $1,800 per car sold, with the total gross from those sales not covering the monthly fee. That is one dealer’s account from one market, but the method is the transferable part.
Check Cost Per Sale Rooftop to Rooftop
The same platform can more than double in cost per sale between two of your stores, driven by market density, inventory, and lead handling. If one rooftop looks twice as expensive on the same platform, that is a signal to fix lead handling or attribution there.
Take Real Questions Into the Renewal Call
When your rep calls, have a short list ready.
| Ask this | What it tells you |
|---|---|
| What tier am I on, and what exactly does it include? | Whether you are paying for placement or for features you never use |
| How is my price set against comparable dealers in my market? | Whether your rate reflects your market or your renewal history |
| What am I paying for add-ons on top of the base listing? | How much of the invoice is optional |
| Can you show me the leads-to-connections data behind my subscription? | Whether the lead volume you are billed for is reaching a human |
| What was my cost per sale on your platform last quarter, against the gross I made on those units? | Whether the platform is profitable for you, in your own margin terms |
Renewal pricing is a recurring complaint in dealer forums. In one r/askcarsales thread from December 2025, dealers reported jumps such as $1,084 to $1,550 a month, and an Autotrader renewal moving from $1,800 to $2,300. Those are individual reports from a single thread, not a survey, but they match what reps rarely volunteer: how your rate compares to the dealer down the road. Walk in with your own numbers so the conversation is about value, not just the new price.
Rented Leads Versus Owned Channels and AI Search
Renting marketplace placement and owning your own channel behave differently over time, and cost per sale is where you see it.
Marketplace costs are recurring and tend to climb. The filings show revenue per dealer holding steady or rising as the platforms upsell tiers and add-ons. Your own channels — your website, your Google Business Profile, and your content — cost more upfront and then compound, because the traffic and authority you build do not reset to zero every month.
In one account, over a single month, we saw the dealer’s own website call-to-action convert at 28% and 12.8% across two rooftops with almost no bad leads, while the best rented marketplace sub-channel topped out at around 9%. Owned traffic converted several times better that month and carried no recurring per-lead charge. One month at one group, again, is a signal rather than a benchmark.
There is a newer reason the owned side matters. A growing share of buyers now start with an AI assistant rather than a marketplace, and those assistants answer from your website, your Google Business Profile, and third-party records about you — not from your marketplace subscription tier. Generative Engine Optimization (GEO) is the work of making sure the assistant names your store, and it is the one channel a competitor cannot simply outbid you for.
Marketplace spend buys you placement for as long as you keep paying. GEO and organic search buy you an asset. Cost per sale is how you decide the split between them.

Third-Party Lead Cost FAQs for Dealerships
How much do dealers actually pay Cars.com?
The average Cars.com dealer pays about $2,500 a month, roughly $30,000 a year, for subscription products. That figure comes from the company’s Q2 2026 results, which report Monthly Average Revenue Per Dealer of $2,500 across 19,343 dealer customers and exclude digital advertising and the DealerClub wholesale product.
What does CarGurus cost a dealer?
The average US CarGurus dealer pays about $2,711 a month. CarGurus reports this quarterly rather than monthly: US Quarterly Average Revenue per Subscribing Dealer was $8,134 for Q2 2026 across 26,151 US paying dealers, which works out to roughly $2,711 a month. Premium tiers and large groups pay more.
What are Autotrader’s dealer fees?
Autotrader does not publish dealer fees. Its parent, Cox Automotive, is privately held and does not report per-dealer revenue figures the way Cars.com and CarGurus do, so the only reliable figure for your store is your own invoice.
Should I credit the first click or the last click for a sale?
Credit the first source, meaning the platform where the buyer first entered your funnel, not the last click before they signed. Last-click attribution over-rewards whichever channel happens to close the deal and starves the channels that actually found the buyer.
