Dealer Participation on a Car Loan (Rate Markup)
What is dealer participation on a car loan?
Dealer participation, also called dealer reserve or rate markup, is the difference between the rate a lender approves, called the buy rate, and the higher rate the dealer writes into your contract. The lender pays the dealer part of that extra interest. Louisiana caps the spread at 3 points and California at the equivalent of 2.5. On $20,000 over 60 months, 2 points over a 14.6% buy rate costs $21 a month.
Key takeaways
- The CFPB describes dealer participation, or reserve, as compensation a lender pays a dealer based on the difference in interest between the lender's buy rate and the higher rate in your contract.
- Two percentage points of markup on a $20,000, 60-month loan at a 14.6% buy rate, the Federal Reserve's average for subprime borrowers at traditional lenders, costs $21 a month and $1,269 in extra interest.
- California caps dealer participation at what a 2.5% annual rate would earn on contracts of 60 monthly payments or less (2% on longer ones), and Louisiana bars a buy-rate-to-contract-rate gap of more than 3 points. Most states leave the limit to each lender's dealer agreement.
- Federal consent orders with Honda, Fifth Third and Toyota in 2015 and 2016 capped dealer markup at 1.25 points on loans of 60 months or less and 1 point on longer loans; those orders ran three to five years, have expired, and rested on a disparate-impact theory the CFPB disavowed in a 2026 rule.
- The markup is negotiable. Asking what the buy rate is, and asking for the deal at buy rate, is a normal conversation at a finance desk.
- Dealer-arranged financing at a marked-up rate can still be the best available option if your own bank or credit union has declined you.
What is dealer participation on a car loan?
Dealer participation is the extra interest a dealer earns by writing your contract at a higher rate than the lender approved. The CFPB describes it as compensation the lender pays the dealer "based upon the difference in interest revenues between the buy rate and the actual note rate charged to the consumer."
When a dealer arranges your financing, it sends your application to lenders. A lender that wants the deal responds with a [buy rate](/glossary/buy-rate/), the rate at which it will purchase that contract from the dealer.
The dealer then writes the retail installment contract with you. It may write it at the buy rate, or at a higher rate. If it writes it higher, the lender pays the dealer a share of the extra interest. That share is dealer participation, also called dealer reserve, rate participation, or simply the markup.
Nothing about it is hidden in the sense of being illegal. It is standard indirect-lending compensation, and most states do not require the buy rate to be disclosed to you.
What does a dealer markup cost?
They are two different numbers and only one of them appears on your paperwork.
| Buy rate | Contract rate | |
|---|---|---|
| Who sets it | The lender, based on your credit tier, the vehicle, and the structure | The dealer, within the lender's cap and any state limit |
| Where you see it | Not on your contract | On your contract, as the APR |
| Who it benefits | The lender's pricing | The dealer's finance office |
Here is what two percentage points cost on a typical subprime deal, using 14.6% as the buy rate, the Federal Reserve's weighted average for subprime borrowers at banks, credit unions and finance companies.
| Buy rate 14.6% | Contract rate 16.6% | |
|---|---|---|
| Amount financed | $20,000 | $20,000 |
| Term | 60 months | 60 months |
| Payment | $472/mo | $493/mo |
| Total interest | $8,297 | $9,566 |

$21 a month, $1,269 over the term. That is the entire difference between the two contracts, and everything else about them is identical.
Who limits how much a dealer can mark up the rate?
Mostly the lender, through its dealer agreement. Two states cap it by statute, California and Louisiana, and federal regulators once imposed lower caps on three large lenders. Each row below comes from the statute, the order, or the rule itself.
| Limit | What it allows | Status | Source |
|---|---|---|---|
| Each lender's dealer agreement | Set lender by lender. Before their consent orders, Honda capped markup at 2.25 points on contracts of 60 months or less and 2 points on longer ones; Toyota at 2.5, 2 and 1.75 points depending on term | Private contracts | CFPB consent orders, 2015–2016 |
| California Civil Code §2982.10 | A dealer can't receive more from the lender than a 2.5% rate would earn on contracts of 60 monthly payments or less, or 2% on longer contracts | In force | California Legislature |
| La. R.S. 32:1261(A)(2)(k) | A dealer can't participate in a finance charge that leaves more than 3 percentage points between the buy rate and the contract rate, and must disclose in writing that it may be participating | In force for transactions under the Louisiana Motor Vehicle Sales Finance Act | Louisiana Legislature |
| Consent orders: Honda (2015), Fifth Third (2015), Toyota (2016) | Dealer discretion capped at 1.25 points on contracts of 60 months or less and 1 point on longer ones | Expired after 3 to 5 years; based on a disparate-impact theory | CFPB |
| CFPB Bulletin 2013-02 | Guidance that indirect lenders could be liable under the Equal Credit Opportunity Act for discriminatory dealer markups | Voided by Congress in Public Law 115-172, May 21, 2018 | Congress |
| Equal Credit Opportunity Act and Regulation B | Credit discrimination on a prohibited basis, including in pricing, is illegal | In force; since July 21, 2026, Regulation B says ECOA does not support disparate-impact (effects test) claims | CFPB rule, 91 FR 21620 |

The California and Louisiana ceilings are not rates you should expect to pay; they are the most a dealer may collect. The consent orders show how much lower a markup can run, and federal enforcement has since stepped back, which makes the question "what is the buy rate?" your own protection anywhere.
Is it negotiable?
Yes. This is the single most useful thing to know about it. The FTC says the APR you negotiate with a dealer usually includes an amount that compensates the dealer for handling the financing, and tells buyers to negotiate the APR just as they would the price of the car.
The finance manager has discretion within the lender's cap, and reducing or removing the markup is a decision they are allowed to make. Dealers give it up routinely to close deals, to hold a customer who is shopping, or to make a payment fit.
Two questions do the work:
- "What is the buy rate on this approval?" Some managers will tell you. Some will not, and that answer is informative too.
- "Will you write it at buy rate?" This is a normal request, not an accusation.
Bring a competing approval if you can get one. A pre-arranged offer from a credit union is the strongest form of this conversation, because the dealer now has to beat a real number rather than argue about an abstract one.
Does a buy-here-pay-here lot charge dealer participation?
Not in this sense, because there is no outside lender and no buy rate to mark up. At a buy-here-pay-here lot the dealer is the lender, so the cost is the rate itself, and the Federal Reserve found subprime borrowers paid a weighted average of about 25.4% at those dealers against 14.6% at traditional lenders.
That gap is larger than any markup on the table above. If a dealer can place your loan with an outside lender, even a marked-up rate is usually cheaper than in-house financing; see buy here pay here.
When is the markup worth paying?
It is worth saying plainly: the dealer did work, and the work has value.
If your credit union declined you and the dealer placed the deal with a lender that approved it, the marked-up rate is the only rate you have. Refusing it on principle leaves you without a car. The markup on a subprime deal is also small relative to the rate itself: two points on top of a 14.6% buy rate is meaningful, but it is not the reason the rate is in the teens. That is the credit tier, and it is set before the dealer touches anything.
So the target is not zero markup. The target is knowing the number exists, asking about it, and not paying more than you had to for the same approval.

Common questions
What is dealer participation on a car loan?
It is the share of extra interest a lender pays a dealer for writing your contract above the lender's buy rate. Two points of markup over a 14.6% buy rate on $20,000 for 60 months adds $21 a month and $1,269 in interest.
Is there a legal limit on dealer markup?
In two states, yes. Louisiana bars a gap of more than 3 points between the buy rate and the contract rate, and California limits the dealer to what a 2.5% rate would earn on contracts of 60 monthly payments or less, or 2% on longer ones. Elsewhere, each lender's dealer agreement sets the limit.
Do I have to be told the buy rate?
Generally no. Your contract shows only the rate you pay, and most states do not require the buy rate to be disclosed; Louisiana requires a written notice that the dealer may be participating in the finance charge. You can still ask what the buy rate is and ask for the deal at that rate; some finance managers will answer.
Does a buy-here-pay-here lot charge dealer participation?
Not in this sense, because there is no outside lender and no buy rate. The dealer is the lender, so the cost is the rate itself, which the Federal Reserve found averaged about 25.4% for subprime borrowers at buy-here-pay-here dealers.
Is dealer markup the same as discrimination?
Not by itself. Consent orders from 2015 and 2016 found that discretionary markups left some lenders' African-American and Hispanic borrowers paying more, using a disparate-impact theory. A CFPB rule effective July 21, 2026 says that theory doesn't apply under ECOA; intentional discrimination remains illegal.
