Mileage is the second-biggest driver of used-car value after model year. As a US benchmark, every 10,000 miles above the average of 12,000 per year reduces resale value by roughly 8–12%. The penalty is steepest between 60,000 and 120,000 miles, then flattens out — past 150,000 miles, condition matters more than the odometer.
Quick answer
- US average: 12,000 miles per year (FHWA).
- Penalty: ~8–12% loss per 10,000 miles above the age-adjusted average.
- Sweet spot for buyers: 40,000–80,000 miles — best price per remaining-life ratio.
- Diminishing returns: after 150,000 miles, mileage matters less than maintenance records.
- Brand matters: Toyota and Honda lose less per mile than domestic and European brands.
The rough formula dealers use
Most dealer pricing tools (Manheim MMR, Black Book, KBB Trade-In) start with the year/make/model/trim base price, then apply a mileage adjustment computed against the expected mileage for that age, not zero. A 5-year-old car is expected to have around 60,000 miles. If it has 90,000, the adjustment penalizes the extra 30,000 — not the full 90,000.
The Taziky estimator uses the same logic: VIN-derived spec, comparable auction sales, and a mileage adjustment relative to age-expected miles. Try it and watch the breakdown.
Mileage depreciation by band
| Mileage band | Typical resale impact | Notes |
|---|---|---|
| 0–30,000 | Premium (+5 to +10%) | Low-mile cars sell above book. |
| 30,000–60,000 | Near book value | Most common range; pricing is competitive. |
| 60,000–100,000 | −10 to −20% | Steepest drop. Buyers fear timing belts and major services. |
| 100,000–150,000 | −20 to −35% | Below book. Maintenance records are essential. |
| 150,000+ | −35 to −55% | Mileage matters less than condition past this point. |
Brand and segment differences
A 100,000-mile Toyota Camry retains noticeably more value than a 100,000-mile BMW 3 Series of the same year. Brands with strong reliability reputations — Toyota, Honda, Lexus, Mazda — take a smaller hit per 10,000 miles. European luxury (BMW, Audi, Mercedes) and most domestic SUVs depreciate faster on mileage because buyers price in expected repair cost.
Pickup trucks are the exception. A high-mileage F-150, Silverado, or Ram with documented service often sells closer to book value than a comparable sedan, because the buyer pool values them as work vehicles.
When are low miles a red flag?
Unusually low mileage on an older car can be a warning, not a feature. Reasons to be cautious:
- Odometer rollback: NHTSA estimates 450,000 vehicles per year in the US have rolled-back odometers.
- Long storage: a car parked for years can have dry rot, cracked hoses, and degraded fuel systems.
- Salvage rebuild: some rebuilders advertise "low miles" without disclosing a salvage history.
- Fleet swap: some VINs show low miles because a different cluster was installed during repair.
Always cross-check the odometer reading against Carfax service records, state inspection history, and NMVTIS title brands.
How mileage affects trade-in vs private sale
Mileage hurts trade-in value more than private-sale value. Dealers price for resale risk and target a 20–25% margin, so a high-mileage trade-in is double-discounted. A private buyer who plans to drive the car as their daily is more forgiving — they care about maintenance records and how it drives, not its place on the wholesale curve.
Translation: if your car is over 100,000 miles, you typically capture 10–20% more by selling privately than trading it in, even after the time and effort.
Key takeaways
- The US baseline is 12,000 miles per year. Compare against age-expected miles, not zero.
- Each 10,000 miles above expected costs roughly 8–12% of resale value.
- The biggest drop happens between 60,000 and 120,000 miles.
- Past 150,000, condition and service records matter more than the odometer.
- Toyota and Honda lose less per mile than European luxury and most domestic SUVs.
- Trucks defy the curve — high miles plus documented service still hold value.
Frequently asked questions
What is considered high mileage on a used car in 2026?
Anything more than 15,000 miles per year of vehicle age is above-average. So a 5-year-old car with 80,000+ miles is high-mileage by US standards.
Is 200,000 miles too many to buy?
Not for Toyota, Honda, Lexus, or pickup trucks with full service records. For European luxury or used CVT-equipped sedans, 150,000 is usually the practical ceiling.
How much value does a car lose per mile?
Roughly $0.08–$0.15 per mile above expected, depending on brand. The cheaper the car, the lower the per-mile cost in dollars but the higher in percentage terms.
Do dealerships pay more for low-mileage trade-ins?
Yes — but the premium maxes out around 30,000 miles below expected. After that, dealers do not pay much more because they cannot price the vehicle far above book.
Does mileage matter more than age?
No. Model year is the single biggest valuation factor. Mileage is second. A newer high-mileage car usually sells for more than an older low-mileage one of the same model.
