How used car loan rates are set

Your interest rate on a used car loan depends on three main things: your credit score, the age and condition of the car, and the lender you choose. Lenders use your credit score as the strongest predictor of whether you'll repay the loan on time. A higher credit score typically means a lower rate; a lower score means a higher rate. The difference can be several percentage points, which adds up to thousands of dollars over the life of the loan.

The car itself also matters. Older cars and those with higher mileage carry higher rates because they're more likely to break down, leaving you unable to make payments. A 2015 model will have a different rate than a 2010 model at the same lender. Lenders also look at the car's market value — if the loan amount is close to what the car is worth, the rate goes up because the lender has less cushion if they need to repossess and sell it.

Different lenders set different rates for the same borrower. Banks, credit unions, and online lenders all price risk differently. Credit unions often offer lower rates to members than banks do. Shopping around for rate quotes before you buy can save you hundreds of dollars.

Key Takeaways

  • Your credit score is the single biggest factor in your rate; scores above 700 typically get rates 2 to 4 percentage points lower than scores below 620.
  • The age of the car affects your rate because older vehicles are riskier for lenders to finance.
  • The loan-to-value ratio — how much you're borrowing compared to what the car is worth — influences your rate, so a larger down payment lowers your rate.
  • Credit unions often offer lower rates than banks and online lenders, but you must be a member to borrow from them.
  • Getting rate quotes from multiple lenders before you buy takes an hour and can reveal differences of 1 to 3 percentage points.

Credit score ranges and typical rate bands

Lenders group borrowers into credit score ranges, and each range has its own typical rate band. These bands shift over time and vary between lenders, but the pattern is consistent: higher scores get lower rates. A borrower with a score of 750 or above will see rates roughly 2 to 4 percentage points lower than a borrower with a score of 580 to 619. That gap means paying tens of thousands more in interest over a five-year loan.

Your score also determines whether you get approved at all. Borrowers with scores below 580 may find that only subprime lenders will work with them, and those lenders charge significantly higher rates. Some lenders have a minimum score requirement — often 620 or 650 — below which they won't lend, regardless of other factors.

If your score is lower than you'd like, you have options. Waiting a few months while you pay down debt or dispute errors on your credit report can raise your score. Some lenders also allow a co-signer with a better score, which may lower your rate. Getting pre-approved before you shop for a car lets you know your actual rate range instead of guessing.

How vehicle age and mileage affect your rate

Lenders typically charge higher rates for cars older than 10 years or with more than 100,000 miles. The exact cutoff varies by lender. Some will finance a 15-year-old car; others won't go past 12 years. Mileage matters because high-mileage cars fail more often, and a broken-down car means a borrower who can't work and can't pay.

The relationship between age and rate isn't linear. A 2019 model might be 0.5 percentage points higher than a 2021 model, but a 2010 model might be 1.5 to 2 percentage points higher than a 2015 model. Lenders have historical data on which model years and makes are reliable, and they price that in. A well-maintained Honda Civic with 120,000 miles might get a better rate than a neglected Chrysler with 80,000 miles.

You can sometimes offset a higher rate on an older car by offering a larger down payment. If you put down 30 percent instead of 10 percent, the lender's risk drops, and they may lower your rate by 0.25 to 0.5 percentage points. The trade-off is worth calculating: paying more upfront to save on interest over five years.

Down payment size and loan-to-value ratio

The loan-to-value (LTV) ratio is the amount you're borrowing divided by what the car is worth. If you're buying a $10,000 car and putting down $2,000, your LTV is 80 percent. Lenders prefer lower LTV ratios because they have more equity to recover if they repossess the car. An LTV of 80 percent or lower usually qualifies for the lender's best rates; an LTV above 100 percent (borrowing more than the car is worth) is rare and expensive.

A larger down payment lowers your LTV and typically lowers your rate. The difference is usually 0.25 to 0.75 percentage points for every 10 percentage points of LTV you improve. On a $15,000 loan, that 0.5 percentage point difference saves you roughly $400 over five years. If you have the cash, putting down more upfront is often worth it.

Down payment size also affects how long you can finance the car. Most lenders won't finance a used car for longer than 72 to 84 months, and older cars have shorter maximum terms. A smaller down payment on an older car might force you into a shorter loan term, which means higher monthly payments even if your rate is lower.

Where to get a used car loan

You have three main sources: banks, credit unions, and online lenders. Banks offer convenience and a wide range of loan terms, but their rates are often higher than credit unions'. Credit unions typically offer the lowest rates, but you must be a member, and membership requirements vary. Some credit unions are open to anyone in a geographic area; others require you to work for a specific employer or belong to a specific organization.

Online lenders and fintech companies have grown in the used car market. They often approve borrowers with lower credit scores and offer faster funding, but their rates are usually higher than banks or credit unions. Some online lenders specialize in subprime lending and may be your only option if your score is very low.

Dealership financing is another route, but it's usually the most expensive. Dealerships work with multiple lenders and take a commission on the loan, which gets passed to you as a higher rate. You can sometimes negotiate the rate at a dealership, but you'll almost always get a better deal by bringing your own financing from a bank or credit union.

Getting rate quotes and comparing offers

Before you buy a car, get rate quotes from at least three lenders. Most banks and credit unions will give you a pre-approval letter with a rate and maximum loan amount. Online lenders can often give you a quote in minutes. These quotes are usually good for 30 to 60 days, so you can shop for a car knowing exactly what you'll pay.

When you compare quotes, look at the annual percentage rate (APR), not just the interest rate. The APR includes fees and other costs, so it's the true cost of borrowing. A quote with a lower interest rate but higher fees might have a higher APR than a quote with a slightly higher interest rate and no fees.

The loan term also affects your monthly payment and total interest paid. A 60-month loan has lower monthly payments than a 48-month loan, but you pay more interest overall. A 72-month loan spreads payments even further, but you risk owing more than the car is worth if it depreciates quickly. Most financial advisors recommend keeping the term to 60 months or less for used cars.

Why rates change and what affects them over time

Interest rates in the used car market move with the Federal Reserve's benchmark rate. When the Fed raises rates, lenders raise their rates too. When the Fed cuts rates, lenders eventually cut theirs, though the lag can be weeks or months. Economic conditions, inflation, and the lender's own cost of borrowing money all play a role.

Your personal rate also changes if you refinance. If you took out a loan at 8 percent and your credit score has improved, you might refinance at 6 percent after a year or two. Refinancing has costs — process fees, title transfer fees — so it only makes sense if you'll save enough in interest to cover those costs and still come out ahead.

Market conditions for used cars also shift your rate. When used car prices are high and inventory is low, lenders tighten their terms and raise rates because they're taking on more risk. When prices fall and inventory rises, rates often drop. Checking rates across multiple lenders over a few weeks can show you whether the market is moving in your favor.

Frequently Asked Questions

What credit score do I need to get a used car loan?

Most traditional lenders require a score of 620 or higher, though some banks and credit unions have minimums of 650 or 700. Scores below 620 can still get financing, but only from subprime lenders at much higher rates. If your score is below 620, waiting a few months to improve it or finding a co-signer may save you thousands in interest.

Can I get a lower rate if I have a co-signer?

Yes. A co-signer with a higher credit score can lower your rate by 1 to 3 percentage points. The co-signer is legally responsible for the loan if you don't pay, so most lenders require a co-signer to have a score of at least 700. Make sure the co-signer understands the commitment before you ask.

Is it better to finance through the dealership or bring my own loan?

Bringing your own financing from a bank or credit union is almost always cheaper. Dealership rates are typically 1 to 3 percentage points higher because the dealership takes a commission. The only exception is if a dealership is offering a special promotional rate — which is rare for used cars — that beats your pre-approval rate.

How much does a larger down payment actually save me?

Every 10 percentage points of down payment typically saves 0.25 to 0.75 percentage points on your rate. On a $15,000 loan at 7 percent for 60 months, putting down 20 percent instead of 10 percent saves roughly $300 to $900 in total interest. Calculate your specific savings using a loan calculator before deciding whether to deplete your savings.

What if my rate seems too high compared to what others are getting?

Shop around with at least three more lenders. Rates vary widely, and you may find a lender that prices your risk differently. If your score is lower or the car is older, some lenders specialize in those situations and offer better rates than mainstream banks. Getting multiple quotes takes a few hours and can reveal savings of hundreds or thousands of dollars.
