No federal rule sets a car down payment; lenders decide. A common rule of thumb is about 20% on a new car, and federal data show why it helps: in CFPB loan data, borrowers whose cars were later repossessed started with an average loan-to-value of 117%, versus 99% for those who kept their cars.
Borrowers who made a cash down payment averaged $7,984 on new and $4,976 on used vehicles (CFPB, 2018 to 2022). On a $40,000 car at the Fed’s 7.14% average 60-month rate, 20% down lowers the payment from about $795 to about $636 and saves about $1,537 in interest.

The down payment is the one part of a car deal that lowers every other number at once: the amount financed, the monthly payment, the total interest and the risk of owing more than the car is worth. Average new-car loans are large; finance companies reported an average amount financed of $41,705 over 67 months in June 2026, according to the Federal Reserve (Fed G.19). This guide shows how much buyers actually put down, how loan-to-value math works, and how to pick a down payment that fits your budget.
How Much Do Car Buyers Actually Put Down?
The best federal data come from the CFPB’s auto finance data pilot, which collected loan-level records from large banks, finance companies and captive lenders. Its January 2025 report compares servicemembers with other borrowers for loans originated from 2018 to 2022 (CFPB report, PDF):
| Measure (2018-2022, non-servicemember borrowers) | New vehicles | Used vehicles |
|---|---|---|
| Share of loans with no cash down payment | 27.7% | 24.6% |
| Average cash down payment, among those who made one | $7,984 | $4,976 |
| Average loan-to-value ratio | 93.3% | 105.1% |
Two points stand out. More than a quarter of new-vehicle loans had no cash down payment. And the average used-vehicle loan was larger than the vehicle’s price, which happens when taxes, fees, add-ons or negative equity from a trade-in are financed.
What Is Loan-to-Value, and Why Does It Matter?
Loan-to-value (LTV) is the loan amount divided by the vehicle price, times 100. The CFPB uses this definition in its research. A $36,000 loan on a $40,000 car is a 90% LTV; a $44,000 loan on the same car is 110%.
LTV matters because it shows how much cushion you have if the car is totaled, stolen or sold early. CFPB data link high LTVs to worse outcomes. Among non-servicemember borrowers with loans originated from 2018 to 2020, those whose vehicles were repossessed or surrendered within two years had an average LTV of 117% at origination, compared with 99% for those who were not, along with higher APRs (12.9% versus 6.6%) (CFPB). The CFPB’s negative equity research found that loans including a rolled-over balance averaged a 119.3% LTV, versus 88.9% for loans with a positive trade-in (CFPB).
| LTV range | What it means |
|---|---|
| Under 80% | Strong equity cushion; you are unlikely to owe more than the car is worth |
| 80% to 100% | Some cushion at the start; depreciation can erase it in the early years |
| Over 100% | You owe more than the car’s price on day one; GAP and a shorter term matter more |
How Does Your Down Payment Change the Payment and Interest?
Here is a $40,000 new-car purchase (including taxes and fees for simplicity) on a 60-month loan at 7.14% APR, the Federal Reserve’s Q2 2026 average for 60-month new-car loans at commercial banks (Fed G.19):
| Down payment | Amount financed | Starting LTV | Monthly payment | Total interest |
|---|---|---|---|---|
| $0 (0%) | $40,000 | 100% | $794.69 | $7,682 |
| $4,000 (10%) | $36,000 | 90% | $715.22 | $6,913 |
| $8,000 (20%) | $32,000 | 80% | $635.75 | $6,145 |
Moving from zero to 20% down lowers the payment by about $159 a month and the total interest by about $1,537. It also means the loan starts at 80% of the price instead of 100%.

Is 20% Down Still the Right Target?
The 20% figure is a rule of thumb, not a regulation. It works as a target because it creates a cushion against early depreciation and lowers the interest you pay. But it is not the only right answer:
| Situation | Down payment approach |
|---|---|
| New car, financed for 60+ months | Aim higher (around 20%) to stay ahead of depreciation |
| Used car | A smaller percentage can still keep LTV under 100% if you avoid financing add-ons |
| 0% or very low promotional APR | Interest savings from a big down payment are small; keeping cash in savings may be reasonable, but watch LTV |
| Rolling in negative equity from a trade-in | Extra cash down helps offset the old balance |
| Down payment would empty your emergency fund | Keep the emergency fund; consider a cheaper car instead |
If you are weighing a promotional rate, our guide to 0% financing for 72 months covers what those offers require. Credit matters too: a larger down payment can help with approval and pricing when your score is lower; see our breakdown of average auto loan rates by credit score.
Should You Use Your Trade-In as the Down Payment?
A trade-in with positive equity works like cash. The CFPB suggests researching your car’s value with third-party guides before negotiating, and considering whether selling the car yourself would bring more than the trade-in offer (CFPB). If you owe more than the car is worth, the trade-in reduces your down payment instead of adding to it, and the CFPB’s research shows how that pushes LTV up.
- Get the loan payoff amount from your lender before you shop.
- Get written trade-in offers from more than one buyer.
- On the contract, check that the trade-in allowance and any cash down payment are shown in full.
How Does the Down Payment Affect GAP and Insurance?
If a financed car is totaled or stolen, insurance pays its value, not your loan balance. GAP is designed to cover that difference; the CFPB describes it as optional and notes its price varies greatly (CFPB). With 20% down on a shorter loan, you may never owe more than the car is worth, making GAP unnecessary. With little or nothing down on a long loan, the gap can be large in the first years.
Lenders also generally require collision and comprehensive coverage while the loan is open, according to the NAIC, so budget for full coverage on a financed car (NAIC). The CFPB advises calculating total cost, including taxes, fees, add-ons, insurance and maintenance, not just the monthly payment (CFPB).
How Can You Build a Bigger Down Payment?
- Set a target based on the car you want: 10% to 20% of the out-the-door price.
- Open a separate savings account and automate monthly transfers.
- Sell your current car privately if you have equity and the time to do it.
- Time your purchase; our guide to the best time to buy a car covers when discounts are larger.
- Consider a less expensive model so the same cash covers a larger share of the price.
Frequently Asked Questions
How much should you put down on a car?
There is no legal or regulatory minimum for most auto loans; lenders set their own requirements. Many buyers aim for about 20% on a new car as a rule of thumb, because it keeps the loan below the car’s value from the start. In this article’s example, 20% down on a $40,000 car cuts the 60-month payment from about $795 to about $636 at 7.14% APR.
What is the average down payment on a car?
In CFPB loan data for 2018 to 2022, non-servicemember borrowers who made a cash down payment put down an average of $7,984 on new vehicles and $4,976 on used vehicles (December 2022 dollars). About 27.7% of new-vehicle loans and 24.6% of used-vehicle loans had no cash down payment.
Can I buy a car with no money down?
Often yes, if a lender approves it, but you start the loan owing about as much as or more than the car is worth once taxes and fees are financed. CFPB data show borrowers whose cars were repossessed had an average loan-to-value ratio of 117% at origination, versus 99% for those who were not.
What is loan-to-value on a car loan?
Loan-to-value (LTV) is the amount you borrow divided by the vehicle’s price or value, shown as a percentage. The CFPB found average LTVs of 93.3% for new-vehicle loans and 105.1% for used-vehicle loans among non-servicemember borrowers from 2018 to 2022.
Do I need GAP insurance if I put money down?
A larger down payment reduces the need. GAP covers the difference between your loan balance and the insurance payout if the car is totaled or stolen, so it matters most when you owe more than the car is worth. The CFPB says GAP is optional and can be declined.
