New vs. Used Car Loans: Rates, Terms, and Total Cost
May 30, 2026
The new-versus-used decision is not only about the sticker price. The two paths differ in loan rates, available terms, depreciation, and warranty coverage — and all of those feed into what the car really costs you over the years you own it.
Why used-car loans cost more
Lenders generally charge higher APRs on used cars than on new ones. A used vehicle is harder to value, may have unknown history, and is worth less as collateral, so the lender prices in more risk. The gap varies, but used-car rates commonly run a couple of percentage points above new-car rates at the same credit tier.
Used loans may also have shorter maximum terms, especially on older or higher-mileage vehicles, because lenders do not want the loan to outlast the car. That can push the monthly payment up even when the price is lower.
Your credit tier still drives the rate in both cases — prime borrowers (scores around 720 and up) see the lowest APRs, while near-prime and subprime borrowers pay more. The credit-score guide breaks down the typical ranges.
Why new cars lose value faster
The flip side is depreciation. A new car typically loses a large share of its value in the first few years — value you absorb as the owner. A used car has already taken its steepest depreciation hit, so a used buyer effectively lets the first owner pay for that drop.
This is the core tension: new cars borrow cheaply but depreciate fast; used cars depreciate slowly but borrow expensively. Which wins depends on the specific cars and how long you keep them.
Comparing the true cost
To compare fairly, look at the full picture for each option over the same ownership window:
- Purchase price (and therefore the loan amount).
- APR and term available for new versus used.
- Expected depreciation over the years you will own it.
- Warranty and repair exposure. A new car is under full warranty; a used car may be out of warranty and carry higher repair risk.
- Insurance, which is often higher on newer, more valuable vehicles.
The cleanest way to compare the financing side is to model both in the auto loan calculator: enter each car’s price, the down payment, and the APR and term you would actually get, then compare the monthly payment and total interest.
A practical middle ground
Many buyers find the best value in a lightly used or certified pre-owned (CPO) car — typically two to four years old. It has shed the worst of the depreciation, often still carries some manufacturer warranty, and CPO programs sometimes qualify for new-car-like financing rates. That can capture much of the depreciation savings without the full used-car rate penalty.
The bottom line
New cars finance cheaply but lose value quickly; used cars hold value better but cost more to borrow against and may have shorter terms. There is no universal winner — it comes down to the individual cars, your credit, and your time horizon. Decide your budget first using the 20/4/10 rule, then run both options through the calculator so you are comparing total cost, not just the price on the windshield.
