What Actually Determines Your Auto Loan Rate?
You found the car, and you know the price. Now comes the question that can change what that car actually costs:
What interest rate will you get?
There isn’t one universal auto loan rate that applies to everyone. Two people can finance similar vehicles for similar amounts and receive different rates because the lender is evaluating more than the car.
That’s known as risk-based lending. The rate and loan terms offered are based on factors related to the borrower and the loan itself.
Understanding those factors before you apply can help you know what to expect and where you may have some control.
Your credit matters, but it isn’t the only factor
Your credit profile is an important part of an auto loan decision.
Lenders may look at your credit score along with the information behind it, including your payment history, outstanding debt, how much available credit you’re using and recent applications for credit.
Generally, a stronger credit profile can qualify for more favorable loan terms because it suggests a lower risk of missed payments.
But your credit score is not the whole application.
The Consumer Financial Protection Bureau notes that auto lenders may also consider your income, debts, loan amount, loan term, down payment and the vehicle itself when determining an interest rate.
That’s important because it means a single number does not determine your rate.
How much you borrow can change the picture
The vehicle may cost $35,000, but that does not necessarily mean you are borrowing $35,000.
Your down payment, trade-in, taxes, fees, optional add-ons and any balance still owed on a trade-in can all affect the amount financed.
A larger down payment reduces the amount you need to borrow. It can also change the relationship between the amount of the loan and the vehicle’s value, commonly called the loan-to-value ratio, or LTV.
Why does that matter?
The vehicle serves as collateral for an auto loan. From a lending perspective, financing a smaller percentage of the vehicle’s value may represent less risk than financing an amount that is close to, or even higher than, what the vehicle is worth.
That is one reason your down payment can matter beyond simply lowering the monthly payment.
Loan term matters too
A longer loan term can make an expensive vehicle look much more affordable because the balance is spread over more months.
But monthly payment is only one part of the decision.
Stretching a loan over a longer period can mean paying interest for longer. It may also increase the chance that you owe more on the vehicle than it is worth at some point during the loan.
When comparing options, look at the term alongside the APR and total amount you’ll repay.
Ask yourself: Would I still choose this car if I focused on the total cost instead of the monthly payment?
That question can quickly change how a deal looks.
Your existing debt and income also matter
A lender wants to know whether another monthly payment fits alongside the financial obligations you already have.
That means your income and existing debt may be considered as part of the application.
Credit cards, mortgages, student loans, personal loans and other payments can affect how much room you have for a new auto payment.
This is also why being approved for a certain amount does not automatically mean you should spend that amount.
Your lender can evaluate whether you qualify for the loan. You still have to decide whether the payment fits comfortably into your life after insurance, gas, maintenance and everything else in your budget.
The vehicle can affect the loan
The car itself matters too. Lenders may consider whether a vehicle is new or used, its age, its value and the amount being financed.
An older vehicle may have different financing terms than a newer one. The same can be true for vehicles with higher mileage or lower market values.
This is another reason shopping for financing before falling in love with one particular car can be helpful. Knowing your financing options gives you a better idea of which vehicles fit the whole budget, not just the sticker price.
Interest rate and APR are not the same thing
This is worth knowing when you compare auto loans.
The interest rate is what the lender charges you to borrow the money.
The annual percentage rate, or APR, reflects the interest rate plus certain additional loan fees. Because lenders are required to disclose APR, it can be a useful way to compare financing offers.
Just make sure you are comparing similar loans.
A lower APR attached to a much longer term may not necessarily be the better deal for your budget. Compare the APR, amount financed, term, monthly payment and total cost together.
Why advertised rates may not be the rate you receive
You have probably seen auto financing advertised with language such as “rates as low as.”
Those rates generally apply to borrowers who meet specific credit qualifications and other loan requirements. The rate offered to you may be different based on your credit profile, amount financed, loan term and other factors.
Hughes uses risk-based lending for auto loans, which means eligible borrowers may receive different rates based on their individual credit qualifications and loan details.
The important thing is knowing the rate and terms that apply to your loan before you sign.
What can you do before applying?
You cannot control every factor lenders use, but there are a few things worth doing before you start shopping.
Check your credit.
Review your credit report for incorrect balances, unfamiliar accounts or other errors. Hughes members can also use CreditSmart through Hughes Digital Banking to view credit information and better understand factors that may be affecting their score.
Know what payment fits your budget.
Do this before you walk onto the lot. Include insurance, fuel, maintenance and registration in the calculation, not just the loan payment.
Think about your down payment.
A larger down payment can reduce the amount you need to finance. Just be careful not to empty your savings simply to make the car payment smaller.
Shop for financing as seriously as you shop for the car.
Compare offers using APR, loan term and total cost, not just the monthly payment.
Consider getting financing lined up before you shop.
Knowing what you may qualify for can give you a useful reference point when you get to the dealership.
The rate is personal. The homework is the same.
With risk-based lending, your auto loan rate reflects more than the vehicle sitting in front of you. Your credit profile, amount financed, loan term and other details can all play a role.
That makes preparation especially useful.
Check your credit before you shop. Know how much you actually want to borrow. Compare APRs and terms. And look at the total cost before deciding whether the loan works for you.
