The typical down payment ranges from 10 to 20 percent of the car's price, but what you actually put down depends on your credit score, the lender, and whether you're buying new or used.

If you're financing a $30,000 car, a 10 percent down payment is $3,000 and a 20 percent down payment is $6,000. Buyers with strong credit often put down 20 percent or more. Buyers with fair or poor credit may put down less—sometimes as little as 3 to 5 percent—but will pay higher interest rates to offset the lender's risk. Some buyers put down nothing, though zero-down deals are less common now than they were before 2008.

The amount you put down affects your monthly payment, the total interest you'll pay, and whether you'll owe more than the car is worth if you total it. A larger down payment lowers your monthly bill and reduces the risk that you'll be underwater on the loan. A smaller down payment preserves your cash but costs more over time.

Key Takeaways

  • Down payments typically range from 10 to 20 percent of the purchase price, though lenders accept as little as 3 to 5 percent for buyers with lower credit scores.
  • Your credit score is the single biggest factor: borrowers with scores above 740 often put down 15 to 20 percent, while those below 620 may put down 10 percent or less.
  • Used cars often require a higher down payment percentage than new cars because they depreciate faster and lenders see them as riskier collateral.
  • Putting down more than 20 percent rarely changes your interest rate, so the benefit is mainly a lower monthly payment and less total interest paid.

How credit score shapes your down payment

Lenders use your credit score to decide how much risk they're taking. A score above 740 signals you've paid bills on time, so the lender will accept a smaller down payment—often 10 to 15 percent—and offer a lower interest rate. A score between 620 and 739 typically requires 15 to 20 percent down. A score below 620 may require 20 to 25 percent down, or the lender may refuse to finance the purchase at all.

The reason is simple: if you default on the loan, the lender sells the car to recover their money. A larger down payment means they've already recouped part of their loss before the car hits the auction block. The worse your credit, the more cushion they want.

New cars versus used cars

New cars typically allow lower down payments because they hold their value better in the first few years. A lender financing a new $35,000 car may accept 10 percent down ($3,500). The same lender financing a used $20,000 car—which depreciates faster—may require 15 to 20 percent down ($3,000 to $4,000).

Used cars also carry more uncertainty: you don't know the full maintenance history, and mechanical problems can appear after you've signed. Lenders price that risk into their down payment requirement. If you're buying a used car with high mileage or from a private seller rather than a dealer, expect to put down more.

What happens if you put down less than 10 percent

Putting down less than 10 percent is possible but comes with real costs. Your monthly payment rises, and you're more likely to owe more than the car is worth—a situation called being "underwater" or "upside down" on the loan. If you total the car in an accident, your insurance payout may not cover what you still owe the lender, leaving you responsible for the difference.

Lenders also charge higher interest rates for low down payments. A buyer putting down 3 percent might pay 1 to 2 percentage points more in interest than a buyer putting down 20 percent. Over a five-year loan, that difference adds hundreds or thousands of dollars to the total cost.

The trade-off between down payment size and monthly cost

A larger down payment lowers your monthly payment because you're borrowing less money. On a $30,000 car financed over 60 months at 6 percent interest, a $3,000 down payment (10 percent) results in a monthly payment of about $508. A $6,000 down payment (20 percent) results in a monthly payment of about $453. The difference is $55 per month, or $3,300 over the life of the loan.

However, putting down more than 20 percent rarely changes your interest rate. The benefit is purely the lower monthly payment. If you have cash sitting in a savings account earning 4 to 5 percent interest, you might come out ahead by putting down 20 percent and keeping the rest in savings rather than putting down 30 or 40 percent.

Down payments at dealerships versus credit unions and banks

Dealerships often advertise low or zero down payment deals, especially on new cars. These offers are real, but they come with higher interest rates to compensate for the lender's increased risk. A dealership might offer zero down at 7.5 percent interest, while a credit union offers 10 percent down at 5.2 percent interest. Over five years, the credit union deal costs less even though you put more money down upfront.

Credit unions and banks typically require higher down payments but offer lower interest rates. If you're a member of a credit union, get a pre-approval before you visit a dealership. Knowing your rate and down payment requirement gives you leverage to negotiate and helps you spot when a dealership's offer is actually more expensive.

How to decide what to put down

Start by checking your credit score and getting pre-approved by at least one lender. This tells you what down payment percentage they'll accept and what interest rate you'll pay. Then compare the total cost of different scenarios: 10 percent down, 15 percent down, and 20 percent down. Most lenders' websites have calculators that show monthly payment and total interest for different down payment amounts.

If you have the cash and your savings account is earning less than your loan's interest rate, putting down 20 percent usually makes sense. If your savings is earning 4 to 5 percent and your loan rate will be 5 to 6 percent, the difference is small enough that keeping more cash on hand for emergencies may be worth it. Never drain your emergency fund to make a larger down payment—a car repair or job loss will force you to borrow at a much higher rate.

Frequently Asked Questions

Is 10 percent down enough to get approved for a car loan?

Yes, if your credit score is 700 or higher. Lenders with scores below 700 may require 15 to 20 percent. If you're denied at one lender, try a credit union or a lender that specializes in lower-credit borrowers, though their interest rates will be higher.

Can I use a gift or loan from family as my down payment?

Yes, but lenders require proof that the money is a gift, not a loan you'll have to repay. If it's a gift, get a signed letter from the family member stating it doesn't need to be repaid. If it's a loan, the lender will count the monthly payment as debt when calculating whether you can afford the car.

What if I don't have enough for the down payment the lender wants?

You have three options: save longer, buy a cheaper car, or find a lender with lower down payment requirements. Some lenders accept 3 to 5 percent down, but their interest rates are significantly higher. Calculate the total cost before choosing this route.

Does putting down 30 or 40 percent get me a better interest rate?

No. Most lenders set their interest rate based on your credit score and the loan term, not the down payment amount. Anything above 20 percent down just lowers your monthly payment—it doesn't improve your rate.

Should I put down my entire tax refund on a car?

Only if you have three to six months of expenses in savings already. A tax refund is a one-time payment, and using it for a down payment leaves you vulnerable if your car breaks down or you lose income. Keep the refund in savings and put down what you can afford to lose without creating financial stress.
