New vs. Used Car: How to Decide in 2026

The short version: The sticker gap between a new car and a three-year-old version of the same car is far larger than the gap in what they actually cost you to own. Depreciation favors the used car heavily. Financing, repairs and the absence of a factory warranty push back hard in the other direction. In the worked example below, a used car priced 34 percent below the new one produced a five-year saving of about 6 percent. That does not make used a bad idea. It means the decision should be made on five-year totals using the interest rates you are actually quoted, not on the difference between two window stickers.

What depreciation actually costs

Depreciation is the largest single cost of owning a new car, and the one buyers think about least, because no bill ever arrives for it. The AAA Your Driving Costs study, published September 15, 2026, put the average annual cost of owning and operating a new vehicle at $12,863, based on five years and 75,000 miles and an average new-vehicle sticker price of $39,376. Of that annual total, $4,422 was depreciation alone, more than fuel and maintenance combined.

The five-year picture comes from iSeeCars, which analyzed more than 950,000 five-year-old used cars sold between March 2025 and February 2026. It found average five-year depreciation of 41.8 percent, an average loss of $16,571. That was an improvement on its prior-year study, which measured 45.6 percent, meaning vehicles held value slightly better in the most recent period.

The misconception about driving off the lot

Almost everyone has heard that a new car loses twenty percent of its value the instant it leaves the dealership. No agency, valuation firm or academic study publishes that figure, and it is not measurable in the way the claim implies. What is real is less dramatic and more useful to understand.

The moment you take delivery, your car stops being worth its retail asking price and becomes worth what someone would pay you for it. Kelley Blue Book publishes those as separate values for a reason: a dealer’s asking price includes reconditioning, floorplan interest, commission and advertising, none of which transfer to you. That spread exists on day one, on day one thousand, and on the day you sell. Nothing dropped. You simply moved from one side of the counter to the other. The genuine first-year loss is the steepest of any year, but it is a market movement spread over twelve months rather than a cliff at the exit gate, and its size varies enormously by model.

What happened to the used market after 2020, and where it stands now

Between 2020 and 2022, semiconductor shortages cut new-vehicle production, rental fleets sold down their inventory, and buyers who could not get a new car bid up used ones. The Bureau of Labor Statistics used cars and trucks index rose at rates without modern precedent, and for a period some two-year-old vehicles sold for close to their original sticker price.

That has unwound, but incompletely, and the two most-watched indicators currently point in opposite directions. The Bureau of Labor Statistics reported that in August 2026 the consumer price index for used cars and trucks was down 2.3 percent over twelve months, while new vehicles were up 0.6 percent. Meanwhile the Cox Automotive Manheim Used Vehicle Value Index reached 215.3 in March 2026, up 6.2 percent year over year and the highest reading since the summer of 2023, with Cox attributing the rise to healthy demand and tight inventory.

Those are not contradictory so much as different. Manheim measures wholesale auction prices, which is what dealers pay. The consumer price index measures what retail buyers pay, which moves later and is smoothed differently. The practical reading is that used prices are not collapsing and are unlikely to return to their pre-2020 relationship with new prices soon. The old assumption that a lightly used car is always a bargain relative to new needs testing every time rather than taking on faith.

The costs that move in the other direction

Financing

This is the factor most commonly left out of the comparison, and it is large. The Experian State of the Automotive Finance Market report for the second quarter of 2026 put the average annual percentage rate at 6.35 percent for new vehicles and 11.19 percent for used. The gap holds across every credit band.

Two things drive the gap. Used collateral is worth less and is harder to value, so lenders price in more risk. And automakers subsidize new-car rates to move inventory, which nobody does for used cars. The lower your credit score, the more the used-car penalty compounds, which is a perverse outcome given who buys used cars.

Insurance, registration and repairs

Insurance usually falls with vehicle value, but only the collision and comprehensive portion does. Liability coverage, the larger share for many drivers, tracks the damage you might cause to others and barely moves. The AAA 2026 figure for a new vehicle with full coverage was $2,098 a year. Expect a used car to come in lower, but not proportionally lower.

Registration is a state matter and genuinely varies. Many states assess an annual fee scaled to vehicle value or age, so an older car costs less. Others charge a flat fee where age makes no difference at all. AAA put license, registration and taxes at $802 a year averaged across states for a new vehicle.

Repairs go the other way. The AAA 2026 study put maintenance, repair and tire costs at 11.7 cents per mile for a new vehicle across its first five years, a period in which most of it is under warranty. A car being driven from year three to year eight is past that protection and into the range where suspension, brakes, tires, batteries and accessory drive components come due.

Reliability data worth trusting, and certified pre-owned

Three sources are worth your time. Consumer Reports runs an annual member survey covering hundreds of thousands of vehicles and reports trouble spots by model and year, which is the right granularity for a used-car decision. The J.D. Power U.S. Vehicle Dependability Study, released February 12, 2026, surveyed 33,268 original owners of 2023 model-year vehicles after three years and found an industry average of 204 problems per 100 vehicles, two more than the prior year and the highest since the study was redesigned in 2022. Infotainment systems accounted for 56.7 of those problems per 100 vehicles. And the National Highway Traffic Safety Administration complaint, investigation and recall databases are free, searchable by vehicle identification number, and unfiltered by any commercial interest.

Certified pre-owned programs sit between the two paths and are more limited than the badge suggests. The Toyota Certified Used Vehicles program, at its Gold tier, covers vehicles within six model years and under 85,000 miles, requires a 160-point inspection, and provides a limited comprehensive warranty of one year or 12,000 miles from the purchase date plus powertrain coverage of seven years or 100,000 miles measured from the original in-service date. The Honda program requires a 182-point inspection, accepts vehicles under 80,000 miles, and provides powertrain coverage to seven years or 100,000 miles from the original in-service date, with a non-powertrain limited warranty running two years beyond the end of the new vehicle warranty or to 100,000 total miles, and no deductible.

Read those terms carefully. The long number is almost always powertrain only and dated from when the car was first sold, not from when you bought it. On a four-year-old car, seven years from original in-service date leaves three years, not seven. The genuinely valuable part is usually the short comprehensive warranty and the inspection.

A worked five-year comparison

Take the AAA average new vehicle at $39,376, with $4,376 down, financed over 60 months at the Experian new-car average of 6.35 percent. Against it, assume the same model at three years old for $26,000, with $2,000 down, financed over 60 months at the used average of 11.19 percent. The used price is an assumption for this example, not a published average. Fuel is excluded because it is essentially identical.

New-car depreciation uses the iSeeCars 41.8 percent five-year rate applied to $39,376. Insurance, registration and maintenance for the new car are the AAA 2026 figures at 15,000 miles a year. The used car’s depreciation, insurance, registration and repair figures are estimates, deliberately chosen to be favorable on value loss and unfavorable on repairs, which is the realistic shape.

The sticker gap is $13,376, or 34 percent. The five-year cost gap is $2,730, or about 6 percent, roughly $546 a year. Almost the entire advantage of buying used is consumed by a higher interest rate and a post-warranty repair bill.

Decision rule: compare the two paths on five-year totals using the interest rates you have actually been quoted, not on sticker price. If the used car you are considering is less than roughly a third cheaper than the new equivalent, assume the two cost about the same and decide on condition, warranty coverage and documented reliability instead.

Three things shift this materially. Paying cash removes the financing gap entirely and swings the arithmetic decisively toward used. A manufacturer-subsidized rate of zero or two percent on a new car swings it the other way. And a model with a known expensive failure in the used years can erase the saving with a single repair, which is exactly what the reliability databases are for.

One more variable rarely makes it into the comparison: how long you actually keep cars. Every figure above is a five-year total. If you replace vehicles every three years, you sit in the steepest part of the depreciation curve on the new car and never reach the years where the used car’s repair bills accumulate, which tilts the result further toward used. If you keep cars for a decade, the new car’s depreciation is spread thinner and its warranty-covered early years count for more. Decide your holding period first, then run the numbers over that period rather than over an arbitrary five years.

Where these figures come from

Ownership cost components, the $12,863 annual total, the $4,422 depreciation figure, the $39,376 average sticker price, and the insurance, registration and maintenance rates are from the AAA Your Driving Costs 2026 study, released September 15, 2026, based on five years and 75,000 miles. Five-year depreciation of 41.8 percent and the $16,571 average loss are from the iSeeCars study of more than 950,000 five-year-old vehicles sold between March 2025 and February 2026, with the 45.6 percent figure from its prior-year study. Interest rates by credit tier are from the Experian State of the Automotive Finance Market report for the second quarter of 2026. Used and new vehicle price movements are from the Bureau of Labor Statistics Consumer Price Index release for August 2026 and the Cox Automotive Manheim Used Vehicle Value Index for March 2026. Dependability figures are from the J.D. Power 2026 U.S. Vehicle Dependability Study, released February 12, 2026. Certified pre-owned terms are from the published program terms for Toyota Certified Used Vehicles and Honda Certified Pre-Owned. Value definitions are Kelley Blue Book’s own.
