How Junk Car Offers Are Calculated, Step by Step

This guide follows that process from the first question we ask to the moment you’re paid. It explains why each question matters and what you can do to make the number reliable.

Step 1: Identify the vehicle

The first thing any buyer needs is the exact vehicle. We ask for:

• Year, make and model
• Trim and engine, if you know them
• The VIN, the 17-character vehicle identification number

The VIN removes guesswork. It confirms the exact build, which tells us the weight and which parts the car came with. Two cars with the same model name can differ by engine, body style and drivetrain, and those differences change the value.

Step 2: Set the metal baseline from weight

Next, the car’s curb weight sets a baseline. Heavier vehicles carry more steel, and steel is the bulk of what gets recycled.

That baseline is tied to the scrap market. Metal prices change over time, so the same car can be worth slightly more or less depending on when you sell. This is why a quote has an expiry: Badger Junk Cars quotes are valid for 48 hours.

For a closer look at the weight math itself, see how weight affects your offer.

Step 3: Adjust for completeness

Then we adjust for what’s actually on the car. This step can move an offer more than any other.

We’ll ask about:

• The catalytic converter. Is the original still in the exhaust line?
• Wheels and tires. Are all four on, and do they hold air?
• Engine and transmission. Present, even if they don’t work?
• Battery, alternator and starter. In place?
• Body and glass. Any missing doors, panels or windows?

Each part that’s present adds recovery value. Each one that’s missing comes off. A complete car that doesn’t run is often worth more than a running car that’s been stripped.

Step 4: Note the condition and the pickup

Last, we note anything that affects the work of removing and processing the car:

• Does it roll? Seized wheels or a car with no tires take more effort to load.
• Where is it? Driveway, street, garage, back lot.
• Fire or flood damage. These lower parts value.

Towing is free either way. These questions just make sure the right truck shows up and the quote doesn’t need to change.

How the four inputs become one number

Put together, the offer is the metal baseline plus the parts that are present, adjusted for condition, all measured against the current market. Our offers land between about $200 and $1,000 per vehicle.

Not every buyer works this way. Some quote by weight only and ignore parts. Others give a generous phone number and plan to cut it at pickup. Knowing the inputs lets you tell which kind of quote you’re looking at.

You can get a starting junk car value estimate on our value page, then call to turn it into a firm offer.

What’s checked at pickup

When our driver arrives, they check that the car matches the quote:

1. The VIN matches the vehicle you described.
2. The parts you said were there are there.
3. The paperwork is in order: normally your signed Wisconsin certificate of title and a photo ID.

If everything matches and you’re inside the 48-hour quote window, you’re paid the quoted amount in cash and the car is loaded.

How to read a quote fairly

When you compare offers, ask each buyer three things:

• Is it firm? Get a clear answer.
• What would change it? A fair buyer names specific things, like a missing part you didn’t mention.
• What do I actually receive? Confirm towing is free and there are no fees subtracted at pickup.

A slightly lower firm offer with free towing often beats a higher number that shrinks at the curb. For the owner’s-eye view of the same factors, read what drives your car’s value.

The takeaway

Every fair junk car offer comes from the same four inputs, and knowing them helps you spot a quote that won’t hold. More plain-English guides are on the Guides hub. For a firm number, call (414) 367-7245, Monday to Saturday.
