Over five years, buying a used car typically costs you significantly less than buying new, despite potentially higher maintenance bills. When you factor in the full equation—purchase price, depreciation, maintenance, insurance, and finance charges—a used car comes out ahead in almost every scenario. As of December 2025, the average new car costs $47,100 while a comparable used car runs $29,600, creating a $20,000 gap that’s the largest ever recorded. Even accounting for extra repairs, that used vehicle will almost always save you money.
The math is straightforward but powerful. A new car loses 20–25% of its value in the first year alone, averaging $4,334 in depreciation annually. A used car, already past that cliff, depreciates more slowly. Meanwhile, monthly payments on a new car average $737–$772, compared to $520–$570 for a used car—a $200–$252 monthly advantage that compounds over 60 months. Over five years, that’s $12,000 to $15,000 in payment savings before we even discuss maintenance.

THE PURCHASE PRICE ADVANTAGE—WHY USED CARS START AHEAD
The opening move in this financial game is decisive: used cars cost significantly less upfront. The December 2025 market shows new car prices at an all-time average of $47,100, while used cars average $29,600. That’s not a small difference—it’s a structural advantage that used cars maintain throughout ownership. This gap exists because dealers know new car buyers accept depreciation as the cost of having latest-year models and full factory warranties. Used car shoppers, by contrast, are explicitly accepting an older vehicle to save money.
The $20,000 price difference translates directly into lower monthly payments. If you finance a new car at typical current rates, you’re looking at $737–$772 per month. A used car financed over the same 60-month period averages $520–$570 monthly. That’s $12,000 to $15,000 in payment savings before interest or a single maintenance bill. For a concrete example: a buyer choosing between a 2025 Toyota Camry at $35,000 and a 2021 Camry at $18,000 saves $17,000 at purchase. Even if that 2021 model needs $3,000 in repairs over five years, the used car remains ahead by $14,000 in pure cash outflow—and that’s ignoring all other costs.
DEPRECIATION—WHERE YOUR MONEY GOES (OR STAYS)
New cars are depreciating assets from the moment you drive them off the lot. According to Kelley Blue Book data, a new vehicle loses 20–25% of its purchase price in the first year. On a $47,100 car, that means $9,425–$11,775 vanishes in year one. Annual depreciation continues at roughly $4,334 per year for new vehicles, meaning a $47,100 car might be worth only $30,000–$32,000 after three years of ownership. Used cars have a crucial advantage here: they’ve already absorbed that catastrophic first-year hit.
A four-year-old car loses value much more slowly than a brand-new one. The same Camry example illustrates this: the $18,000 used car depreciates more slowly in percentage terms. If it loses $2,000 in value over five years (an aggressive estimate), you’ve still come out far ahead compared to the new car’s $15,000+ total depreciation. There’s a critical limitation to understand, though: buying a very old used car (10+ years) can flip this script. Extremely aged vehicles may face mechanical failures that turn a small depreciation problem into a large repair problem. The sweet spot for used cars is typically 3–7 years old—old enough that the steep depreciation curve has flattened, but new enough that major systems haven’t yet begun failing.
MAINTENANCE AND WARRANTY COVERAGE
New cars enter ownership with a significant advantage: factory warranties. Typical new vehicle warranties cover 3–5 years and many miles, meaning your primary maintenance concern is just oil changes and tire rotations. AAA data from 2025 shows new cars cost an average of $126 monthly for maintenance ($1,512 yearly), but much of that is preventive work covered by warranty. Used cars lack that safety net, though many dealers offer limited used-car warranties of 30–90 days. Once that expires, you’re responsible for all maintenance and repairs.
For a 5–7 year old used car, AAA data suggests $800–$1,000 yearly in maintenance costs—higher than the new car’s warranty-covered years, but the actual gap is narrower than it appears. The new car’s $1,512 annual maintenance cost is still a legitimate expense; it’s just covered by warranty. Once that warranty expires (typically at year 3–5), new cars also begin facing real repair costs. The real risk with used cars is catastrophic failure: a transmission going out at year four can cost $3,000–$4,000, a scenario that would be covered under a new car’s warranty. This is the legitimate downside. But spread across 60 months, even a $3,000 disaster rarely erases the $12,000+ purchase-price advantage. It’s a risk calculation, not a guarantee of losing money.
TOTAL COST OF OWNERSHIP OVER FIVE YEARS
When every cost is combined—payments, fuel, insurance, maintenance, registration, depreciation—AAA’s 2025 data shows owning a new car costs $11,577 annually, or $964.78 monthly. Over five years, that’s $57,885 in total ownership cost. For a used car, the calculation depends on the specific vehicle, but the framework is clear: lower payments ($520–$570 vs. $737–$772) and slower depreciation offset higher maintenance costs.
Taking a realistic used car scenario: a $29,600 purchase with $550 monthly payments for 54 months ($29,700 total), $900 yearly maintenance ($4,500 over five years), $1,500 annual insurance ($7,500), $200 yearly registration ($1,000), and 10–15% total depreciation ($4,440–$6,660). That rough total: $47,640–$49,860 over five years, compared to the new car’s $57,885. The used car saves approximately $8,000–$10,000 over five years in this realistic comparison. That’s not a trivial difference when you’re thinking about your household budget.
HIDDEN COSTS AND FINANCIAL RISKS
Insurance premiums, often overlooked, typically run $1,694 annually for full coverage. Used cars benefit here too: insurance companies charge less to cover a $20,000 vehicle than a $47,000 one. Comprehensive and collision coverage on used cars can be 10–20% cheaper. Over five years, that compounds. The bigger hidden risk is financing.
New car loans are typically cheaper (better rates) than used car loans, sometimes by 1–2% in interest rate. If you’re financing a $29,600 used car at 8% instead of the new car’s 6%, that extra interest adds up. On a $29,600 loan at 8% over 60 months, you’ll pay roughly $4,300 in interest versus $2,800 at 6%. That $1,500 difference matters, though it doesn’t erase the purchase-price advantage. The warranty limitation deserves emphasis again: if a used car needs a major repair in year two or three, before you’ve saved enough to absorb the cost, you could face genuine financial stress. This argues for either having an emergency fund before buying used or choosing slightly newer used vehicles (3–4 years old) with remaining manufacturer warranty.
THE RELIABILITY QUESTION
A persistent myth: used cars are unreliable, new cars are perfect. The reality is messier. Some model years have severe design flaws; others, even at 10 years old, run without issue.
A used Camry or Honda Accord at 100,000 miles is often more reliable than a brand-new vehicle with untested production quality. The practical approach: use tools like Kelley Blue Book’s reliability ratings, Consumer Reports historical data, and specific VIN history checks (CARFAX, AutoCheck) to evaluate the actual used car you’re considering, not used cars as a category. A well-maintained 2019 model with full service records is a completely different proposition than a neglected 2019 with unknown history. For the used car path to work, you need to do homework on the specific vehicle, not just assume.
WHEN NEW CARS MAKE FINANCIAL SENSE
There are scenarios where new cars make sense despite their cost. If you plan to keep a car 10+ years, the lower depreciation cost amortized over that period approaches the used car advantage. A car driven for 15 years absorbs depreciation losses over 180 months instead of 60, making the per-month cost smaller.
Reliability certainty matters if your income depends on never being stranded. A ride-share driver or someone with a long commute and no backup transportation might rationally choose the warranty protection and reliability guarantee of a new car despite the cost premium. The financial math says used cars win; life context sometimes points elsewhere. Your decision should account for both.
Conclusion
The five-year cost comparison strongly favors used cars. The $20,000 purchase-price gap is the dominant factor, creating a structural advantage that survives realistic maintenance costs, depreciation, and insurance differences. Even assuming the used car requires $3,000–$4,000 in unexpected repairs, you’re still $8,000–$12,000 ahead over five years.
The catch: used car purchases require active evaluation and carry risk. You’re gambling on specific vehicle reliability instead of relying on factory warranty. If you’re willing to do your homework, check service records, review reliability ratings, and maintain an emergency fund for repairs, the math strongly favors going used. If you prioritize simplicity and absolute reliability over cost, a new car’s warranty provides real peace of mind—just go in knowing that peace of mind costs $8,000–$10,000 over five years.
