What makes a car loan cheaper
A cheaper car loan means a lower interest rate, which cuts the total amount you pay back. The rate you get depends on three things: your credit score, how much you put down, and the length of the loan. A higher credit score gets you a lower rate. A larger down payment reduces what you borrow, so you pay less interest overall. A shorter loan term means you pay interest for fewer months, though your monthly payment goes up.
The lender also matters. Banks, credit unions, and online lenders often have different rates for the same borrower. Credit unions typically offer lower rates than banks if you are a member. Shopping around — getting rate quotes from at least three lenders — is the single most effective way to find a cheaper loan, because the difference between lenders can be hundreds of dollars over the life of the loan.
Key Takeaways
- Your credit score is the biggest factor lenders use to set your rate, so checking your score before you shop tells you what range to expect.
- Credit unions usually offer lower rates than banks or online lenders, but you must be a member to borrow from them.
- Getting pre-approved for a loan before you visit a dealership shows you your actual rate and prevents the dealer from marking it up.
- A larger down payment reduces the amount you borrow and the total interest you pay, even if it does not change your rate.
- Comparing rates from at least three different lenders takes an hour and can save you hundreds of dollars over the loan term.
How your credit score affects the rate you are offered
Lenders use your credit score to decide how risky it is to lend you money. A higher score means you have a history of paying bills on time, so lenders charge you less interest. A lower score means more risk to them, so they charge more. The difference is real: someone with a score of 750 might get a rate of 4%, while someone with a score of 620 might get 9% for the same car and loan amount.
You can check your own credit score for free through AnnualCreditReport.com, which is the official site for the three credit bureaus. Many banks and credit card companies also show your score free in their online accounts. Knowing your score before you shop for a loan helps you understand what rate range to expect and whether it makes sense to wait and improve your score first.
If your score is low, you have options. Paying down existing debt, correcting errors on your credit report, and waiting for negative marks to age can all improve your score over time. Even a 20-point improvement can lower your rate by half a percent or more. If you need a car now, you can still shop for the best rate available to you, then refinance later once your score improves.
Where to get pre-approved before you shop
Pre-approval means a lender has reviewed your finances and told you the rate and terms they will offer you, before you actually explore for the loan. Getting pre-approved from at least two or three lenders before you visit a dealership protects you in two ways: you know your real rate, and you can walk in knowing you have financing lined up elsewhere.
Credit unions are often the cheapest source. If you belong to one, call or visit their website to ask about auto loans. Many credit unions let you pre-explore online and get a rate quote within hours. If you do not belong to a credit union, you can often join one through your employer, your school, or a professional association you are part of.
Banks and online lenders are the next places to check. Most banks let you start the pre-approval process online. Online lenders like LendingClub, Upstart, and others often give you a rate quote in minutes without a hard credit pull (a hard pull temporarily lowers your score, but multiple pulls for the same type of loan within two weeks usually count as one). Dealerships also offer financing, but their rates are usually higher than what you can get on your own — and they may mark up a rate you bring to them.
Why a larger down payment saves you money
Your down payment is the cash you put toward the car upfront. The rest is what you borrow. If a car costs $20,000 and you put down $5,000, you borrow $15,000. If you put down $8,000, you borrow $12,000. You pay interest only on the amount you borrow, so a larger down payment means less interest overall.
A down payment also improves your chances of getting approved and getting a better rate, because you are borrowing less relative to the car's value. Lenders see this as lower risk. If you can put down 20% or more of the car's price, many lenders will offer you better terms than if you put down 10% or less.
If you do not have a large down payment saved, that is okay — many people finance most of the car. But if you have any cash available, putting it toward the down payment rather than spreading it across monthly payments will cost you less in the long run.
Comparing loan terms: shorter loans cost less in interest
A shorter loan term means you pay off the car faster and pay less interest. A 36-month loan costs you less in total interest than a 60-month loan for the same car and rate. But the monthly payment on a 36-month loan is higher. You have to decide what monthly payment fits your budget.
Here is a real example: a $15,000 loan at 5% interest costs you $1,596 in interest over 36 months (payment: $448/month) or $1,979 in interest over 60 months (payment: $283/month). The 36-month loan saves you $383 in interest, but your payment is $165 higher each month. If you can afford the higher payment, the shorter term is cheaper overall.
Some people stretch their loan to 72 or 84 months to lower the payment. This costs significantly more in interest and also means you owe money on the car for seven years. If the car breaks down or you want to sell it, you may still owe more than it is worth. Sticking to 48 months or less is usually the better choice if your budget allows it.
Shopping around: how to compare rates from multiple lenders
Getting quotes from multiple lenders takes a few hours but can save you hundreds of dollars. Start with your credit union if you have one, then get quotes from at least two banks and one online lender. Most lenders can give you a rate quote online or over the phone without a hard credit pull, or with a soft pull that does not affect your score.
When you get quotes, write down the rate, the loan term, any fees, and the monthly payment. Make sure you are comparing the same loan amount and term across all lenders — a 48-month loan at one place versus a 60-month loan at another is not a fair comparison. Some lenders charge origination fees or prepayment penalties; others do not. Factor those into your total cost.
Once you have chosen a lender, you can move forward with the full process. Many lenders will lock in your rate for 30 to 60 days, so you have time to find the right car without worrying that your rate will change.
When refinancing makes sense
Refinancing means taking out a new loan to pay off your existing car loan. You might refinance if your credit score has improved since you took out the original loan, or if interest rates have dropped. If you can get a lower rate by refinancing, you can reduce your monthly payment or pay off the car faster.
Refinancing costs money — there are process fees and possibly other closing costs — so it only makes sense if the interest you save is larger than the fees you pay. A rough rule: if you can lower your rate by at least 1% and you have at least two years left on the loan, refinancing is worth exploring. Your current lender or a new lender can tell you the costs and savings.
Refinancing also resets the clock on your loan. If you have two years left on a five-year loan and you refinance into a new five-year loan, you are back to five years of payments. To actually save money, refinance into a shorter term if you can, or at least the same term you had left.
Frequently Asked Questions
Does shopping for rates hurt my credit score?
Multiple rate inquiries from different lenders within a two-week window usually count as a single hard pull on your credit report, so your score drops only a few points. The impact is temporary — it recovers within a few months. Shopping around is worth the small, short-term dip.
What if I have bad credit or no credit history?
You can still get a car loan, but your rate will be higher. Credit unions and some online lenders work with people in this situation. A larger down payment and a co-signer (someone with better credit who agrees to pay if you do not) can both help you get approved and lower your rate.
Is it better to finance through the dealership or get a loan first?
Getting pre-approved from a bank or credit union first is almost always better. You know your rate going in, and you can negotiate the car price separately from the financing. Dealerships often mark up rates or steer you toward longer terms. Bring your pre-approval letter to the dealership and use it as your baseline.
Can I pay off my car loan early without a penalty?
Most car loans have no prepayment penalty, meaning you can pay it off early without extra fees. Check your loan documents or call your lender to confirm. Paying extra toward principal each month or making a lump-sum payment can save you interest and get you out of debt faster.
What is the difference between APR and interest rate?
The interest rate is the percentage you pay on the loan. The APR (annual percentage rate) includes the interest rate plus any fees the lender charges, spread across the year. APR is a more complete picture of what the loan actually costs, so compare APRs when you are shopping between lenders.
