Where to look for your car's value

Your car's value depends on its make, model, year, mileage, and condition — and different websites calculate it differently. The most widely used sources are Kelley Blue Book (kbb.com), NADA Guides (nadaguides.com), and Edmunds (edmunds.com). Each pulls from auction data, dealer listings, and private sales to estimate what your specific vehicle is worth right now in your area.

You'll get three different numbers from these sites: trade-in value (what a dealer will pay you), private party value (what you'd get selling to another person), and retail value (what a dealer would charge a buyer). Trade-in is lowest; private party is middle; retail is highest. For most purposes — insurance, selling, or understanding what you owe — private party value is the number that matters.

A fourth option is TrueCar (truecar.com), which shows actual prices paid for your car in your zip code over the last 30 days. This is real transaction data rather than an estimate, so it's often the most accurate for what your car will actually sell for locally.

Key Takeaways

  • Kelley Blue Book, NADA Guides, and Edmunds are the three main sources, and they often give different numbers for the same car.
  • Private party value is the number most people need — it's what you'd get selling to another person, not a dealer.
  • You'll need your car's year, make, model, mileage, and condition (exterior and interior) to get an accurate estimate.
  • TrueCar shows actual recent sales in your area, which can be more reliable than national estimates.
  • Check all three major sites and average them — one site alone can be off by several hundred dollars.

What information you need before you start

Have your vehicle registration or title handy. You'll need the year, make, model, and trim level — "2019 Honda Civic EX" is more useful than just "Honda Civic." If you don't know the trim, the registration will say it.

You'll also need your current mileage. Write down the exact number from your odometer. Mileage is one of the biggest factors in value — a car with 80,000 miles is worth noticeably more than the same car with 120,000 miles.

Be honest about condition. The websites ask about exterior (paint, dents, rust), interior (upholstery, dashboard, stains), mechanical condition (does it run smoothly, any warning lights), and accidents. If you've had a major repair or accident, mention it — the value will be lower, but the estimate will be accurate.

Step-by-step: Getting your value from Kelley Blue Book

Go to kbb.com and click "Find a Car's Value" or "What's My Car Worth." Enter your car's year, make, and model. The site will ask for the trim level — if you're not sure, select the most common one and you can adjust it later.

Enter your mileage and select your car's condition: excellent, good, fair, or poor. KBB defines these clearly on the page, so read the descriptions rather than guessing. Then enter your zip code — value varies by region, and KBB adjusts for local market conditions.

The site will show you three numbers: trade-in, private party, and retail. You'll also see a range (usually $500 to $1,500 wide) because condition and mileage vary within each category. Write down the private party number — that's what matters for most decisions.

Comparing values across multiple sites

Repeat the same process on NADA Guides and Edmunds. You'll likely get three different numbers. This is normal — each site weights data differently and uses different sources. A car worth $12,500 on KBB might be $12,200 on NADA and $12,800 on Edmunds.

Add the three private party values and divide by three to get an average. This average is your best estimate of what your car is actually worth. If one site is wildly different from the other two (more than $1,000 off), double-check that you entered the same information on all three.

Then check TrueCar for your zip code. If TrueCar shows recent sales of your exact model in your area, that real transaction data is often more reliable than the national estimates. If the TrueCar price is significantly higher or lower than your average, that tells you something about your local market.

Adjusting for special circumstances

If your car has high-demand features — a popular color, low mileage for its year, or recent major repairs — the websites might undervalue it. If you've replaced the transmission, engine, or suspension in the last few years, note that when you describe condition. Some sites let you add notes; others don't, but the information helps you interpret the estimate.

If your car has accident history, flood damage, or a salvage title, the value drops significantly. The websites ask about this, so be truthful — a car with a salvage title might be worth 40 to 60 percent less than the same car with a clean title. If you're not sure about your title status, check your registration or contact your state's DMV.

If you've customized your car heavily — new wheels, lowered suspension, custom paint — the value may not reflect those changes. Most buyers don't pay extra for customization, and some actually prefer stock vehicles. The websites assume stock condition, so your actual value might be lower.

When to use this value and what it means

Use this number if you're selling your car privately, trading it in, or checking what you owe versus what it's worth. If you're buying insurance, your insurer will use their own valuation (usually based on similar vehicles), so this number is informational rather than binding.

If you're financing the car and want to know your equity, subtract what you owe from the private party value. If you owe $10,000 and the car is worth $12,500, you have $2,500 in equity. If you owe more than the car is worth, you're underwater, and you'll need to pay the difference if you sell or trade it in.

Remember that this is a snapshot — your car's value changes as mileage increases, condition changes, and the market shifts. A value from three months ago is less reliable than one from today. If you're making a major decision (selling, trading, financing), get a fresh estimate within a week or two of the transaction.

Frequently Asked Questions

How often does car value change?

Car values shift gradually as mileage accumulates and the model year gets older. Market conditions and supply also matter — used car prices rose sharply during 2021 and 2022, then fell in 2023 and 2024. Check the value again if several months have passed since your last estimate.

Is trade-in value the same as what a dealer will actually offer me?

No. Trade-in value is an estimate; a dealer's actual offer depends on their inventory needs, the car's condition in person, and their profit margin. A dealer might offer less than the estimate or, rarely, more if they need that model. Always get an in-person appraisal before accepting a trade-in offer.

What if the three websites give me very different numbers?

Check that you entered the same year, mileage, trim, and condition on all three. If you did and they still differ by more than $1,000, the local market data might vary — TrueCar's real sales data is often the tiebreaker. You can also get an in-person appraisal from a dealer or independent mechanic.

Do I need to pay for a professional appraisal?

Not for a basic value estimate. The free websites are accurate enough for most purposes. A professional appraisal costs $100 to $300 and is useful only if you need a formal document for insurance, legal, or financing reasons.

What if my car has a loan on it — does that affect its value?

No. The car's market value is the same whether you own it outright or owe money on it. What matters is the difference between the value and what you owe — that's your equity. The loan itself doesn't change the car's worth.
