New vs Used Car Cost: Which Wins When
How depreciation, financing rate, repair risk, and warranty coverage trade off between a new and a used car, and how to compare the two over your real ownership horizon.
Used cars usually have a lower sticker price and a much smaller depreciation hit. New cars usually have lower financing rates, full warranty coverage, and lower repair risk. Which one costs less in total depends on the specific cars, your financing, and how long you plan to keep the vehicle.
Where new tends to win
- Lower interest rates. New-car APRs are often 1–2 percentage points below used-car APRs at the same credit score, because lenders see new cars as lower risk collateral.
- Warranty coverage. Most repair risk in years 1–3 is covered.
- Long horizons. If you keep the car 8–10 years, the cost premium is spread over many miles.
Where used tends to win
- Depreciation already absorbed. The previous owner took the steepest drop; the next 5 years of depreciation are usually flatter.
- Lower insurance. Lower replacement value typically means lower collision and comprehensive premiums.
- Shorter horizons. If you plan to keep the car only 2–3 years, avoiding the new-car depreciation curve is a big deal.
How to compare them honestly
Don't compare monthly payments — compare total cost over your ownership horizon. That total is the financing cost plus depreciation plus insurance, fuel, maintenance, repairs, and registration over the same number of years. A higher monthly payment can produce a lower total cost if depreciation is much smaller.
Use the new vs used calculator to run both sides side-by-side, or build a fuller picture with the total cost of ownership calculator.
Both sides are estimates. Repair risk is the hardest line to predict — a particular used vehicle's history, mileage, and inspection results matter more than averages.
