Buy Rate
What is a buy rate on a car loan?
The buy rate is the rate a lender approves your loan at before the dealer adds anything to it. It is the wholesale price of your financing, and it does not appear on your contract. Two points added on top of an 18.86% buy rate costs $17 a month and $1,000 over 60 months on a $15,000 loan.
Key takeaways
- The buy rate is the lender's rate; the contract rate is what the dealer writes you at. They are frequently not the same number.
- The buy rate is not disclosed on your retail installment contract, and most states do not require it to be.
- Two percentage points of markup on a $15,000 loan over 60 months is $17 a month and $1,000 in extra interest.
- Your credit tier sets the buy rate before the dealer is involved. The markup is the only part of the rate a finance manager can change on the spot.
- Asking what the buy rate is, and asking for the deal at buy rate, is a normal request at a finance desk rather than an accusation.
What is a buy rate?
The buy rate is the interest rate a lender is willing to buy your loan at.
When a dealer arranges financing, it is not lending you its own money. It writes a retail installment contract with you and then sells that contract to a lender. Before it does, the lender tells the dealer what rate it will pay for that contract given your credit tier, the vehicle, and the structure of the deal. That number is the buy rate.
The rate on your paperwork can be the same, or it can be higher. Where it is higher, the difference is dealer compensation — dealer participation, also called reserve or markup.
Where does the buy rate come from?
From the lender's pricing grid, and almost none of it is about you personally.
| What moves the buy rate | Who controls it |
|---|---|
| Your credit tier and score band | Your credit file |
| The vehicle's year, mileage, and book value | The car you pick |
| Loan-to-value — how much you finance against what the car is worth | Your down payment and the price |
| Term length | The structure of the deal |
| The lender's program for that tier that month | The lender |
Notice what is not on that list: how well you negotiate. By the time a buy rate comes back, the pricing has already been decided by a system. The negotiation happens on top of it.
Buy rate versus contract rate
Two numbers, one of which you get to see.
| Buy rate | Contract rate | |
|---|---|---|
| Set by | The lender | The dealer, within the lender's cap |
| Appears on your contract | No | Yes, as the APR |
| Changes with your credit tier | Yes | Yes, plus whatever is added |
| Negotiable at the desk | No | Yes |
Here is what the spread costs. The 18.86% figure is Experian's Q4 2025 average used-vehicle APR for the subprime tier, used here as the buy rate, with two points added as an illustration.
| Buy rate 18.86% | Contract rate 20.86% | |
|---|---|---|
| Amount financed | $15,000 | $15,000 |
| Term | 60 months | 60 months |
| Payment | $388/mo | $405/mo |
| Total interest | $8,277 | $9,277 |
$17 a month, $1,000 over the term. Same car, same lender, same approval.
Can I find out my buy rate?
Sometimes, by asking. There is no law entitling you to it in most states, and no line on the contract where it appears.
Two questions do the work at the desk:
1. "What did the lender approve this at?" Some finance managers will tell you. Some will not, and how the question is handled tells you something either way. 2. "Will you write it at buy rate?" Dealers give up markup routinely — to close a deal, to hold a shopper, or to make a payment fit a budget.
The strongest version of this conversation is not a question at all. It is walking in with a real approval from a credit union or your own bank. Then the dealer is being asked to beat a number rather than defend an abstraction.
Is chasing the buy rate the right fight?
Not always, and this is worth saying plainly before you spend your negotiating energy there.
On a subprime deal the markup is real money, but it is small next to the tier itself. Two points on top of 18.86% is $17 a month. The gap between the subprime tier and the near-prime tier is worth several times that on the same loan. So if you have a choice between arguing about markup and doing something that moves your tier — a larger down payment, a cheaper car with better loan-to-value, or twelve months of on-time payments before you buy — the tier work pays better.
And if your credit union declined you and the dealer found the only lender that said yes, the marked-up rate is the rate you have. That approval had a cost to produce, and the acquisition fee the lender charged the dealer is part of why. Refusing it on principle leaves you without a car.
The goal is not zero markup. It is knowing the number exists, asking about it once, and not paying more than you needed to for the identical approval.
