Financing through a bank or credit union is generally cheaper because it often offers lower, more transparent interest rates and acts as a baseline for negotiation, avoiding potential dealer markup. However, dealerships can offer competitive, manufacturer-backed incentives or 0% APR deals, making it crucial to compare both options before purchasing.
Short answer: in most cases financing through a bank (or credit union) is better for obtaining lower rates, clearer terms, and more negotiating leverage; dealership financing can be competitive when they offer manufacturer promotions or when you value convenience. Choose by comparing rates, total cost, and flexibility.
The average APR for a car loan will depend on what deals are available at the time so it's worth shopping around. Personal loans are often the cheapest way to borrow money to buy a car if you have a good credit rating and can get access to the best deals.
Your Interest Rate From A Bank May Be Lower.
However, dealers commonly raise the interest rate of the car loan they present to you, and pocket the extra money. For example, if a bank preapproved you for $40,000 with a 3% interest rate over 60 months, you'd pay $43,125 with $3,125 in interest over the life of the loan.
Getting a car loan via a bank or credit union is by far the best option for almost everyone. Not only do you get better interest rates which translates to lower payments and cost overall, but you also have negotiating power on your side so you can get a better price on the car.
The best way to finance a car involves getting preapproved from a bank or credit union before visiting the dealership to compare rates, making a significant down payment (15-20% is ideal), keeping loan terms shorter (around 48-60 months), and negotiating the total car price separately from the financing, allowing you to get a lower interest rate and save money long-term. Leasing or other options like PCP/HP exist, but a direct loan with good credit offers the most equity.
The FTC Red Flags Rule requires auto dealerships to have a written Identity Theft Prevention Program (ITPP) to detect, prevent, and mitigate identity theft, especially in financing/leasing, by spotting signs like suspicious documents (altered IDs, mismatched photos), inconsistent application info, or unusual account activity, with consequences for non-compliance including hefty FTC penalties and lawsuits, notes the Federal Trade Commission. Key steps involve identifying vulnerable accounts, spotting specific "red flags," creating detection/response plans, training staff, and regular audits, with a senior manager overseeing the whole program, say Dealertrack and Total Dealer Compliance.
For years, dealerships have been using a tactic called a “four square”—a sheet of paper divided into four boxes where the salesperson will write down your trade value, the purchase price of the vehicle you're buying, your down payment, and your monthly payment.
The cheapest way to buy a car involves paying cash for a reliable, slightly older used car (3-5 years old) from a private seller, avoiding interest, dealer markups, and rapid depreciation, while focusing negotiation on the "out-the-door" price to skip hidden fees and extras, says Bumper, Consumer Reports, U.S. News & World Report, and My Car Credit. If financing, get preapproved from a credit union first to secure a low interest rate before negotiating the car's price separately.
The dealership is going to add on something called the “finance reserve.” This means the dealer adds anywhere from 1-3% to the interest rate the lender offers before they show you the contract. The dealership then keeps the difference, either as a flat fee from the bank or throughout the life of your loan!
The "20% rule" in car buying usually refers to the 20/4/10 Rule, a guideline suggesting you put 20% down, finance for no more than 4 years, and keep total car expenses (payment, insurance, gas, maintenance) to 10% or less of your gross monthly income. This helps prevent overspending by reducing loan amounts, keeping loan terms short to pay less interest, and ensuring total costs don't strain your budget.
There is no minimum credit score required to buy a car, but most lenders have minimum requirements for financing. Most borrowers need a FICO score of at least 661 to get a competitive rate on an auto loan.
Car Loan APRs by Credit Score
Excellent (750 - 850): 2.96 percent for new, 3.68 percent for used. Good (700 - 749): 4.03 percent for new, 5.53 percent for used. Fair (650 - 699): 6.75 percent for new, 10.33 percent for used. Poor (450 - 649): 12.84 percent for new, 20.43 percent for used.
Let's look at some things to keep under your hat while you explore the lot.
Dave Ramsey's core car rules emphasize paying cash, avoiding new cars (unless you're a millionaire), keeping your total vehicle value under half your annual income, and using a strict budget, often suggesting the 20/4/10 rule (20% down, 4-year loan, 10% total car expenses) as a guideline if financing, but preferring no debt at all to avoid depreciating assets trapping you. He stresses buying reliable, used vehicles to prevent debt and build wealth.
Rates and terms are subject to change without notice. Example: A six year fixed-rate loan for a $25,000 new car, with 20% down, requires a $20,000 loan. Based on a simple interest rate of 3.4% and a loan fee of $200, this loan would have 72 monthly payments of $310.54 each and an annual percentage rate (APR) of 3.74%.
To lower your car payment, you can refinance for a lower interest rate, extend the loan term (but pay more interest overall), negotiate with your lender for a loan modification, sell or trade in for a cheaper car, or remove optional add-ons like extended warranties from your loan. Making a larger down payment or extra principal payments reduces the total loan amount and interest, while switching to a lease might offer lower monthly costs but you don't own the car.
