Where to find your car's value
Your car's value depends on its age, mileage, condition, and local market demand — so the number changes depending on where you look and what you're using it for. The most common free tools are Kelley Blue Book (kbb.com), NADA Guides (nadaguides.com), and Edmunds (edmunds.com). Each pulls from different data sources, so you'll often see three slightly different numbers. That's normal.
If you're selling to a dealer, they use their own internal pricing systems and will offer less than the retail value you see online — that gap is how they make money. If you're selling privately, the retail value is closer to what you might actually get, though the final price depends on how quickly you need to sell and how well you describe the car.
For insurance purposes, your insurer may use a different valuation tool entirely. If you need to know what your insurer considers the car worth, call them directly rather than guessing from a website.
Key Takeaways
- Kelley Blue Book, NADA Guides, and Edmunds are free tools that show different values because they use different data — checking all three gives you a realistic range.
- You need your car's year, make, model, mileage, and condition (interior and exterior damage) to get an accurate estimate from any tool.
- Dealer trade-in offers are typically 10 to 20 percent lower than the private sale value shown online.
- Your insurance company may value your car differently than these public tools, so confirm with them if you need the number for coverage decisions.
What information you need before you look
All three major valuation sites ask for the same basic details: your car's year, make, model, trim level (if you know it), mileage, and condition. The condition part matters most because it's where the biggest price swings happen. You'll usually choose from categories like "excellent," "good," "fair," or "poor."
Be honest about condition. "Excellent" typically means no accidents, no major repairs, and minimal wear on the interior. "Good" means it runs well but has normal wear — maybe some small dents, a worn driver's seat, or minor scratches. "Fair" means it has visible damage or mechanical issues that still work but are noticeable. If you're not sure where your car falls, take photos of the interior and exterior damage and compare them to the examples the sites show.
If your car has had major repairs, accidents, or a salvage title, mention that when the tool asks. These details lower the value significantly, and hiding them will only make your estimate wrong.
How dealer trade-in value differs from private sale value
When you trade a car in at a dealership, you're selling it to a business that needs to resell it, fix any problems, and make a profit. That's why their offer is always lower than what you'd see listed for private sale. The gap varies, but expect a dealer to offer 10 to 20 percent less than the private sale value shown on Kelley Blue Book or Edmunds.
Some dealerships use their own valuation software and don't reference public pricing at all. If you want to compare offers, get quotes from at least two or three dealers in your area. Bring your car in person so they can inspect it — a quote over the phone or online is just a starting point.
If you're not trading in but selling privately, the retail value from the major sites is your target. You may need to price slightly lower to sell quickly, or hold firm if you're willing to wait for the right buyer.
Understanding the difference between retail, trade-in, and loan payoff values
Most valuation tools show you three numbers, and they mean different things. Retail value is what a private buyer might pay — it's the highest number. Trade-in value is what a dealer will offer you — it's the lowest. Loan payoff value (sometimes called "wholesale" or "auction" value) is what the car would sell for at an auto auction, used by lenders to decide how much they'll loan against it.
If you still owe money on your car, your lender cares about the loan payoff value because that's what they could recover if you stopped paying. If you're buying a car and financing it, the lender uses this value to set your loan amount. If you're selling privately, you want the retail value. If you're trading in, you get the trade-in value.
Don't assume all three numbers are close. On an older car in poor condition, the gap between retail and trade-in can be several thousand dollars.
Checking local market prices on classified sites
The valuation tools give you a starting point, but the real market in your area might be different. Spend 15 minutes on Craigslist, Facebook Marketplace, or Autotrader and search for cars exactly like yours — same year, make, model, mileage range, and condition. What are people actually asking for them?
This matters because regional demand shifts prices. A truck might be worth more in a rural area where people need them for work, and less in a dense city where most people use public transit. A convertible might command a premium in a warm climate and sit unsold in a cold one. The national average from Kelley Blue Book is useful, but local listings tell you what buyers near you are actually paying.
When you look at listings, note which ones have been up for weeks (the seller may be overpriced) and which sold quickly (the price was probably fair or low). That pattern is more useful than any single listing.
What affects your car's value most
Mileage is the single biggest factor after the year and model. A car with 50,000 miles is worth significantly more than the same car with 150,000 miles. The valuation tools account for this automatically — just enter your actual mileage.
Accident history is the second major factor. A car with one or two minor accidents in its past is worth less than a clean-title car, and the discount varies by how recent the accident was and how severe. You can check accident history using Carfax or AutoCheck (both charge a small fee per report, though some dealers provide them free). If you're buying a used car, always pull a history report before you commit.
Mechanical condition matters too. A car that needs a new transmission is worth thousands less than one that runs perfectly. If you know your car needs major work, mention it when you get your valuation — don't pretend it's in better shape than it is.
When to get your car professionally appraised
If you're selling a car worth more than a few thousand dollars, or if you're dealing with an insurance claim, a professional appraisal may be worth the cost. An independent mechanic or certified appraiser will inspect the car in person, document its condition with photos, and provide a detailed report. This costs between $100 and $300 but gives you a defensible number if there's a dispute.
You might also want a professional appraisal if your car has unusual features — a rare color, custom modifications, or collector status — that the standard tools don't account for. If you're insuring a car for more than its market value, your insurer may require an appraisal before they'll agree to that coverage level.
For most routine situations — selling a regular used car or checking what you owe versus what it's worth — the free online tools are enough. But if the stakes are high or the situation is unusual, the appraisal fee is cheap insurance against getting it wrong.
Frequently Asked Questions
Why do Kelley Blue Book, NADA, and Edmunds show different prices?
Each tool uses different data sources and pricing models. Kelley Blue Book pulls from auction data and dealer transactions, NADA uses insurance claims and dealer reports, and Edmunds uses its own marketplace data. The differences are usually small, but checking all three gives you a realistic range rather than trusting one number.
Is my car worth more if it has low mileage but hasn't been driven in years?
Not necessarily. A car that's been sitting unused often has mechanical problems — dead battery, dried-out seals, fuel system issues — that lower its value despite low mileage. The valuation tools assume normal use. If your car has been stored, mention that when you get it inspected, because a mechanic may find problems that affect the price.
Can I use these values to argue with my insurance company about what my car is worth?
You can try, but insurers use their own valuation databases and may not accept a screenshot from Kelley Blue Book as proof. If you disagree with their valuation, ask them which tool they used and request a detailed breakdown of how they arrived at their number. If you still disagree, you can hire an independent appraiser and submit that report.
What if my car has a salvage title or has been in a major accident?
The valuation tools have fields for this, and selecting "salvage" or "rebuilt" will drop the value significantly — often by 40 to 60 percent or more. A car with a salvage title is much harder to sell and may not be insurable or financeable. If you own one, get a professional appraisal rather than relying on online estimates.
Does the color of my car affect its value?
Slightly. Common colors like white, black, and silver are easier to sell and hold value better. Unusual colors like bright yellow or orange may appeal to fewer buyers and take longer to sell, which can pressure you to lower the price. The valuation tools don't usually account for color, so check local listings to see if your car's color is helping or hurting demand in your area.
