Car Loan Rates in 2025 — What to Expect
According to Experian and the Federal Reserve, the average new car loan interest rate in Q1 2025 is approximately 7.1% for borrowers with good credit. Used car loan rates average approximately 11.3% due to higher lender risk on depreciating collateral. Your actual rate depends heavily on your credit score, loan term, lender type, and whether you are buying new or used.
| Credit Score | New Car Rate | Used Car Rate | Monthly ($35K/60mo) |
|---|---|---|---|
| 781–850 (Super Prime) | 5.1% | 7.2% | $563/mo |
| 661–780 (Prime) | 7.1% | 11.3% | $594/mo |
| 601–660 (Near Prime) | 9.6% | 14.1% | $620/mo |
| 300–600 (Subprime) | 14.2% | 21.4% | $657/mo |
How Much Car Can You Afford?
Financial advisors recommend keeping your total monthly car payment — including insurance — below 15% to 20% of your monthly take-home pay. On a $75,000 salary with approximately $4,500 in monthly take-home pay, the maximum advisable car payment is $675 to $900 per month including insurance. If insurance costs $150 per month, the maximum loan payment is $525 to $750 per month. At a 7.1% rate over 60 months, that supports a loan of approximately $26,000 to $37,000 — or a vehicle price of $31,000 to $44,000 with a typical $5,000 down payment.
A commonly used rule is the 20/4/10 rule: put at least 20% down, finance for no more than 4 years, and keep total vehicle costs including loan and insurance below 10% of gross income. On a $60,000 salary 10% is $6,000 per year or $500 per month for combined loan payment and insurance. This is a conservative standard that protects against being underwater on a depreciating asset.
The Hidden Cost of Long Loan Terms
Longer loan terms lower your monthly payment but dramatically increase total interest paid and create serious negative equity risk. A $35,000 car loan at 7.1% costs $4,857 in interest over 60 months. The same loan over 84 months costs $6,920 in interest — $2,063 more for the privilege of a lower monthly payment. Worse, cars depreciate rapidly in the first three years. A new car loses approximately 20% of its value in the first year and 15% in year two. On an 84-month loan you may owe more than the car is worth for the first four to five years — a situation called being underwater or upside down — making it difficult or impossible to trade in or sell without bringing cash to the table.
New vs Used: The Financial Case
The average new car price in 2025 is approximately $48,000 according to Kelley Blue Book. The average used car price is approximately $28,000. A 2-year-old used vehicle has already absorbed the steepest portion of depreciation — typically 30% to 40% of original value — yet retains most of its functional life. Buying a 2 to 3 year old certified pre-owned vehicle from a reputable dealer combines lower purchase price, lower depreciation risk, and manufacturer warranty coverage. The higher interest rate on used car loans partially offsets the price advantage but rarely eliminates it entirely.
Frequently Asked Questions
What is the average car payment in America in 2025?
According to Experian the average monthly new car payment in Q1 2025 is approximately $735 and the average used car payment is approximately $523. These averages include buyers across all credit tiers. Buyers with excellent credit and larger down payments can achieve significantly lower payments.
Should I finance through the dealer or my bank?
Always get a pre-approval from your bank or credit union before visiting the dealership. Dealers earn profit on financing — called the dealer reserve — by marking up the buy rate from the lender. Knowing your pre-approved rate gives you negotiating power and ensures you recognize when the dealer is offering a genuinely competitive rate versus an inflated one. Credit unions typically offer the lowest auto loan rates available to consumers.
Does a larger down payment save money?
Yes — significantly. A larger down payment reduces the loan amount, total interest paid, and negative equity risk. On a $35,000 vehicle increasing the down payment from $3,500 (10%) to $7,000 (20%) reduces the loan by $3,500 and saves approximately $485 in interest over 60 months at 7.1% — plus eliminates early negative equity exposure. Every $1,000 of additional down payment saves approximately $139 in interest over a 60-month loan at 7.1%.
What is a manufacturer rebate and should I take it?
Manufacturer rebates — also called cash back incentives — reduce the effective purchase price and are separate from dealer discounts. On some vehicles manufacturers offer a choice between a cash rebate and a promotional low-APR financing rate. To determine which is better compare the total cost of the loan with promotional financing versus taking the rebate and financing at your regular rate. Use the rebate field in this calculator to model both scenarios.
