Remember that actual terms, rates, and costs will vary by lender, your credit score, and current market conditions. These calculators provide educational estimates only and do not constitute professional financial advice. Always compare multiple offers and consult a financial professional before making decisions.

How the math works

Value drops faster per mile at higher odometer readings; guides apply a per-mile depreciation curve derived from real wholesale transaction data. The exact cents-per-mile varies by model and age.

How to use this calculator

Enter the car's base value (from KBB/Edmunds) and annual miles driven.
Enter a real cents-per-mile rate typical for the model class.
Read how value erodes each year and at resale.

Frequently Asked Questions

How much does mileage affect car value?+

Each additional mile reduces value by $0.10–$0.30. Cars over 100,000 miles lose 30–40% of value; over 150,000 miles, 50–60%. The 12,000-mile/year average is the benchmark.

What is the average depreciation per mile?+

Compact cars: $0.10–$0.15/mile. Mid-size sedans: $0.15–$0.20/mile. Luxury: $0.25–$0.40/mile. Higher-mileage cars depreciate slower in absolute dollars.

Does high mileage hurt resale more than age?+

Yes—mileage matters more than age for cars under 10 years. A 5-year-old car with 100k miles is worth 20–30% less than one with 50k miles.

At what mileage does value drop most?+

Major drops at 60k (warranty end), 100k (six-figure milestone), and 150k miles. Between milestones, depreciation is gradual.

Can I reduce mileage depreciation?+

Drive less (carpool, transit), keep detailed service records, maintain condition, and sell before 100k miles. Low-mileage cars (under 10k/year) command 15–25% premiums.
