US auto finance data, updated 2024
A car loan — also called an auto loan — is money borrowed from a lender to purchase a vehicle. The borrower repays the principal plus interest in fixed monthly installments over an agreed term. Unlike unsecured personal loans, auto loans are secured: the vehicle serves as collateral, meaning the lender can repossess the car if you default.
Direct vs. Dealership Financing: You can obtain financing directly from a bank or credit union before visiting the dealership ("direct lending"), or arrange financing through the dealership's finance office. Dealers work with a network of lenders, but they add a markup called dealer reserve — legally up to 2.5% APR — to the rate the lender offers them. This markup is profit for the dealership and an extra cost for you.
Manufacturer Incentive Rates: Automakers (via their captive finance arms — Ford Motor Credit, Toyota Financial Services, etc.) sometimes offer promotional 0% or low APR financing. These deals are powerful but often packaged so they exclude large cash rebates. Always calculate both paths — low APR vs. rebate applied as a down payment — to find the true winner.
Loan Term Trend: The average loan term has stretched from 48 months in the 1980s to nearly 69 months today. While longer terms lower the monthly payment, they dramatically increase total interest paid and raise the risk of negative equity — owing more than the car is worth as it depreciates.
// Monthly Payment (Amortization Formula)
M = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
P = Loan principal (car price − down payment − trade-in + sales tax)
r = Monthly interest rate (APR ÷ 12 ÷ 100)
n = Total number of monthly payments (term in months)
M = Fixed monthly payment amount
Example: $25,000 loan at 7.1% APR for 60 months → r = 0.00592, M ≈ $495/mo
// Actual Loan Amount
Loan = Car Price − Down Payment − Trade-In + Sales Tax
Sales tax rates vary by state (0%–10.3%). In most states tax is rolled into the financed amount, increasing both principal and total interest paid.
// Total Cost of Ownership (Finance)
Total Cost = (Monthly Payment × n) + Down Payment + Trade-In Value
Total Interest = (M × n) − P. This is the true cost above the car price you pay purely for the privilege of financing.

General Motors Acceptance Corporation (GMAC) launches the first large-scale automobile financing program in the US, making car ownership accessible to middle-class Americans who could not afford to pay cash upfront. The concept of installment lending for consumer goods is born.
The post-World War II economic expansion drives explosive auto sales. Installment loans become the standard method for purchasing cars. Ford Motor Credit and Chrysler Financial enter the market, and the three-year (36-month) loan becomes the norm for working families.
Vehicle leasing, long used by businesses for fleet management, is introduced to individual consumers as an alternative to traditional ownership financing. Leasing offers lower monthly payments at the cost of building no equity, beginning a decades-long debate about which option is financially superior.
Federal deregulation of the banking industry allows banks, thrifts, and credit unions to compete aggressively in the auto loan market. Average loan terms begin stretching from 36 to 48 months as lenders compete for market share. Manufacturer promotional rates — including the first 0% APR programs — debut.
The global financial crisis results in dramatic tightening of auto lending standards. Subprime auto lending collapses temporarily, average loan terms shorten, and down payment requirements increase. GMAC is restructured into Ally Financial. The industry learns hard lessons about over-extended consumer credit.
Global semiconductor shortages reduce new vehicle inventory to record lows, pushing average transaction prices above $47,000 at peak. To offset unaffordable prices, average loan terms hit 70+ months. Monthly payments exceed $700 on average. Negative equity becomes widespread, with many buyers rolling underwater balances from previous loans into new ones.
Average monthly payment for a new vehicle reached $729, a 5.4% year-over-year increase. Average loan term hit 68.8 months. Leasing share declined to 20% of new-vehicle transactions as consumers absorbed higher sticker prices.
experian.com/automotive →Auto loan balances reached $1.59 trillion in 2023, the highest on record. The average new car APR for a 60-month loan was 7.03% in early 2024, up sharply from 4.5% in 2021 following Federal Reserve rate hikes.
federalreserve.gov →CFPB research shows dealer markup on auto loans adds an average of 1.1% to APR compared to direct bank loans, costing consumers $300–900 over the loan term and disproportionately affecting minority borrowers.

Dealers often focus you on monthly payments to obscure total cost. A lower payment stretched over 84 months can cost $5,000+ more in interest than a 48-month loan on the same car. Always compare total out-of-pocket cost, not just the monthly figure.
“Dealer financing is always more expensive than going direct.”
Manufacturers sometimes offer promotional 0% APR financing that beats any bank or credit union rate. These deals are powerful but often exclude large cash rebates — calculate both options with our calculator. For standard financing, however, dealer markups typically make direct lending from credit unions cheaper.
“You need perfect credit to get a good auto loan rate.”
Buyers with scores 660–720 (near prime) can access competitive rates, especially from credit unions which average 1.5–2% lower APR than banks for the same credit profile. Even borrowers in the 620–659 range have multiple viable lender options.
“A large down payment isn't worth the effort.”
A 20% down payment reduces negative equity risk from day one, typically lowers your APR by 0.25–0.5%, and ensures you are not underwater when the car depreciates 15–25% in year one. Over a 60-month loan, the savings from a better rate alone can exceed $800.
