What Mileage Really Does to a Car's Value (and Why 100,000 Isn't the Cliff You Think)

Mileage is the first number most buyers look at, and often the only one they trust. A car with 30,000 miles feels safe; one with 110,000 feels like a gamble. But the odometer is a blunt instrument. It tells you how far a car has traveled, not how much life it has left or how much value it has actually shed. Understanding how mileage really moves a car's price — and where it stops mattering as much as you'd expect — can save you from overpaying for a low number or walking away from a genuinely good deal.

What "normal" mileage actually looks like

Before you can judge a car as high- or low-mileage, you need a baseline. According to the Federal Highway Administration, the average U.S. driver covered about 13,662 miles in 2023, the most recent year of complete data. That's why the roughly 12,000-to-15,000-miles-per-year range is the yardstick dealers and appraisers use. Multiply it out: a five-year-old car with around 65,000 to 75,000 miles is simply average, not worn out. A car well below that line may look like a bargain, but abnormally low mileage can bring its own problems — rubber seals, gaskets and fluids degrade with age whether or not the wheels are turning.

Context also comes from how long cars now last. S&P Global Mobility reported in May 2025 that the average vehicle on U.S. roads hit a record 12.8 years old, with passenger cars averaging 14.5 years. There are now roughly 289 million light vehicles in operation, and the scrappage rate sits around 4.5% — meaning most cars are staying on the road far longer than the odometer alone would suggest.

The steepest losses happen early

Here's what surprises most people: the biggest hit to a car's value comes long before it looks old. Kelley Blue Book estimates a typical new vehicle loses about 20% of its value in the first year alone, and industry data from sources like Experian puts the total drop at roughly 55% to 60% by the end of five years. A useful rule of thumb ties value loss to distance too — very roughly, a car sheds around 1% of its original price for every 1,000 miles driven, though the pace is anything but even.

Edmunds' analysis is blunt about where that pain concentrates. As senior analyst Ivan Drury put it, "After about the first 40,000 miles, vehicles depreciate at a slow and steady pace. The most dramatic drop-off is actually during the first 20,000 miles." In other words, the person who bought new absorbed the worst of it. By the time a car reaches the used lot with 40,000-plus miles, the value curve has already flattened considerably.

Why 100,000 miles isn't the cliff you think

The six-figure odometer reading carries an almost superstitious weight, but the data doesn't support treating it as a wall. Edmunds found that vehicle values decline only incrementally between 100,000 and 150,000 miles — at a rate similar to the decline between 50,000 and 100,000 miles. Tight supply of late-model used cars has kept demand strong even for higher-mileage vehicles, so crossing 100,000 miles no longer triggers the collapse in value it once did.

Vehicle type matters more than the round number. In Edmunds' analysis, a used midsize SUV with 100,000 miles still retained about 50% of its original value, while a comparable midsize car held roughly 42%. That gap reflects demand, durability reputation and body style — not the odometer. A well-kept truck or SUV with high miles can hold value better than a sedan with far fewer.

Mileage is a proxy, not the whole story

The reason mileage matters at all is that it's a stand-in for wear. But two cars with identical odometers can be worlds apart. Consider what actually shapes a car's condition and value beyond the number itself:

• Type of miles. Highway miles are gentler than stop-and-go city driving. A commuter's 90,000 highway miles may leave a car in better shape than 60,000 miles of short urban trips.
• Maintenance history. Documented, on-schedule service can matter more than the raw mileage. A 110,000-mile car with complete records often beats an 80,000-mile car with none.
• Ownership and use. A single-owner, non-fleet vehicle typically wears more evenly than one passed through several hands or used commercially.
• Model reputation. Some models are known to run well past 150,000 or even 200,000 miles, and their resale values reflect that confidence.

How to use this when you shop

Don't anchor on the odometer alone. Start by comparing the car's mileage to the roughly 12,000-to-15,000-per-year benchmark to see whether it's above or below average for its age. Then weigh that against maintenance records, the type of driving it's seen, and how the specific model holds up over time. A slightly higher-mileage car with a clean service history and a durable reputation is frequently the smarter buy than a low-mileage example that's been neglected or is priced at a premium for its number alone.

The buyers who get the best deals treat mileage as one input among several, not a verdict. That's the same logic tools like LotPilot use when they compare listings across dealers — surfacing the cars whose price, mileage and history line up, rather than the ones that simply flash a low number. Run the full picture, and you'll often find real value sitting a few thousand miles past where most shoppers stop looking.
