Compare the 5-year total cost of buying a new car versus used. Factor in depreciation, insurance, maintenance, and financing to find the better deal.
The decision between buying new and used is one of the biggest financial choices in car ownership. A new car costs more upfront and depreciates faster, but typically has lower maintenance costs, a full warranty, and better financing rates.
A used car costs less upfront with much lower depreciation but may have higher maintenance, shorter warranty coverage, and slightly higher loan rates. Over 5 years, the total cost difference can be $5,000–$15,000 depending on the vehicles and scenarios compared.
This calculator provides a comprehensive 5-year cost comparison that includes purchase price, depreciation, financing, insurance, and maintenance — all the factors that determine the true cost of ownership.
Whether you drive a compact sedan, a full-size SUV, or a pickup truck, accurate new vs used car total cost figures help you plan smarter and avoid costly surprises at the pump or dealership. Use this tool regularly to track changes over time and adjust your transportation budget accordingly.
Comparing just the sticker price misses most of the story. Depreciation, interest, insurance, and maintenance often flip the value equation. This calculator captures all five factors to reveal the true 5-year cost of each option. Results update instantly as you adjust inputs, making it easy to explore different scenarios and find the best option for your driving needs and budget.
5-Year Cost = Purchase Price + Total Interest + (Insurance × 5) + (Maintenance × 5) − Resale Value Resale Value = Purchase Price × (1 − Total Depreciation %)
Result: New: $29,200 | Used: $21,300 (5-yr net cost)
New car ($35,000): loses $15,750 in depreciation (45%), pays $3,200 interest, $8,000 insurance, $2,500 maintenance. Net cost: $29,450. Used car ($22,000, 3 years old): loses $7,700 (35%), pays $2,800 interest, $6,500 insurance, $4,000 maintenance. Net cost: $21,000. Used saves $8,450.
The biggest financial argument for used is depreciation. A $35,000 new car might be worth $19,250 after 5 years (-$15,750). A $22,000 used car (3 years old) might be worth $11,880 after another 5 years (-$10,120). The used buyer saves $5,630 in depreciation alone.
Insurance on a used car is typically 10–25% cheaper than the same model new. Over 5 years, this can save $1,500–$3,000 depending on the model and coverage levels.
Vehicles 2–3 years old with 20,000–40,000 miles are the sweet spot for value. They've absorbed the steepest depreciation, still look and feel relatively new, and have years of reliable life ahead.
Used cars are almost always the better financial choice. A 2–3-year-old vehicle has already lost 30–40% of its value while still being relatively new. The 5-year ownership cost is typically $5,000–$15,000 less than new.
New cars lose about 20–25% in the first year, 10–15% in years 2–3, and 7–10% per year after that. By year 5, a new car retains about 40–55% of its original value depending on the make and model.
Yes, generally. A new car under warranty has minimal maintenance costs ($300–$500/year). A used car may need $800–$1,500+/year as parts age. However, this increase doesn't offset the depreciation savings of buying used.
New car rates are typically 0.5–1.5% lower than used. On a $25,000 loan, that's $400–$1,200 in extra interest over 5 years. It's a factor, but smaller than the depreciation difference.
New cars come with full warranty coverage (typically 3yr/36K bumper-to-bumper +5yr/60K powertrain). This eliminates surprise repair bills. However, CPO used cars offer similar warranty protection at lower overall cost.
Buying new makes sense if you plan to keep the car 8–10+ years (amortizing the depreciation hit), want the latest safety technology, have a strong manufacturer incentive, or highly value having the exact configuration you want.
