Things to Know
Essential concepts for understanding your results
Cost ComponentsWhat are the full costs of owning a vehicle?
AAA estimates the average new car costs $12,200/year ($1,015/month). Breakdown: depreciation $3,500-6,000, fuel $1,500-2,400, insurance $1,700-2,600, maintenance $800-1,400, financing $1,200-2,500, registration/taxes $400-800. Depreciation is the largest component but invisible — it never appears on a statement. A paid-off 5-year-old car costs roughly $5,000-7,000/year — saving $5,000-7,000 annually versus a new car.
DepreciationHow much value does a car lose each year?
Average new car depreciation: 20-25% in year 1, 15% in year 2, 10-12% per year after. A $40,000 car: $30,000 after year 1, $25,500 after year 2, $16,000 after year 5. After 5 years you have lost $24,000 — 60% of purchase price. Trucks and SUVs retain value better (45-55% after 5 years). Luxury cars depreciate fastest (35-40% retained). The optimal financial strategy: buy at 2-3 years old when 35-40% depreciation has already occurred.
Per-Mile CostHow do you calculate the cost per mile to drive?
Cost per mile = Total annual cost ÷ Annual miles. A new car costing $12,200/year driven 15,000 miles = $0.81/mile. A paid-off used car at $6,000/year and 15,000 miles = $0.40/mile. IRS standard mileage rate ($0.67) approximates the average cost. Knowing your per-mile cost helps evaluate decisions: a 30-mile round-trip commute at $0.81/mile costs $5,940/year — relevant when comparing a remote job offer or evaluating whether to Uber instead of owning a second car.
Optimal StrategyWhat is the cheapest way to own a car long-term?
Buy a 2-3 year old reliable vehicle (Toyota, Honda, Mazda) with cash or a 36-48 month loan, maintain it properly, and drive it for 10+ years. Per-year cost drops to $3,500-5,000 versus $10,000-12,000 for buying new every 5 years. Over 30 years of car ownership, this strategy saves $150,000-200,000 — enough to fund a retirement account. The key insight: the cheapest car you can drive is the one you already own and have paid off.
True Cost of Car Ownership Calculator: Beyond the Sticker Price
The true cost of owning a car extends far beyond the purchase price or monthly payment. AAA's 2024 Your Driving Costs study found that the average new car costs $12,297 per year ($1,025/month) to own and operate — including depreciation, financing, insurance, fuel, maintenance, and taxes. Over 5 years: approximately $61,500.

Complete Cost Breakdown
| Cost Category | New Car (Avg) | Used Car (3yr old) | % of Total |
|---|---|---|---|
| Depreciation | $4,500-$6,000/yr | $2,000-$3,500/yr | 35-45% |
| Financing (interest) | $1,200-$2,500/yr | $800-$1,800/yr | 10-18% |
| Insurance | $1,800-$2,800/yr | $1,400-$2,200/yr | 15-20% |
| Fuel | $1,500-$2,500/yr | $1,500-$2,500/yr | 12-18% |
| Maintenance & tires | $800-$1,200/yr | $1,200-$2,500/yr | 8-15% |
| Registration, taxes, fees | $500-$1,200/yr | $300-$800/yr | 3-8% |
| Total Annual | $10,300-$16,200 | $7,200-$13,300 | 100% |
Depreciation is the largest cost — and the one most owners ignore because it is invisible (no monthly bill). A $35,000 new car loses approximately 20% in year 1 ($7,000), 15% in year 2, and 10-12% annually after that. After 5 years: worth approximately $14,000 — you "paid" $21,000 in depreciation alone, or $4,200/year. Buying a 2-3 year old vehicle avoids the steepest depreciation while getting 70-80% of the car's useful life. See our Car Affordability Calculator.
