One of the most common questions we hear at Big Ugly Truck is: how much is my semi truck worth? The honest answer is — it depends. But this guide will walk you through every factor that affects your truck’s value so you can set realistic expectations and make an informed decision.

Factors That Affect Semi Truck Value

Year, Make, and Model

Newer trucks are worth more. Premium brands like Kenworth, Peterbilt, and Volvo tend to hold value better than others. A 2020 Kenworth T680 will command significantly more than a 2010 International ProStar of similar mileage. That said, even older trucks have value — especially if they’re well maintained.

Mileage

Mileage is one of the biggest value drivers in the commercial truck market. Here’s a rough breakdown:

• Under 300,000 miles — high value, strong market demand
• 300,000–600,000 miles — solid value, most common range for active trucks
• 600,000–900,000 miles — value drops significantly but still sellable
• Over 900,000 miles — lower value but we still buy these

Engine and Transmission

The engine is the heart of the truck. A Cummins, Detroit, or PACCAR engine with documented service history is worth more than one with unknown history. Automatic transmissions have become increasingly popular and can add value. If your engine has been rebuilt or recently overhauled, document it — that’s a selling point.

Condition

Condition covers everything from the cab interior to the frame to the fifth wheel. A truck that runs great and looks clean will always get a better offer than one that’s been sitting for a year. But don’t assume a non-running or damaged truck has no value — we buy those too.

Title Status

A clean title is worth significantly more than a salvage or rebuilt title. If your truck has a salvage title, expect offers to be 20–40% lower than a comparable clean-title truck. It still sells — it just prices differently, which is why the title is one of the first things any serious buyer asks about.

Market Conditions

The used truck market fluctuates with freight demand, fuel prices, and the overall economy. During freight booms, used truck prices rise. During slowdowns, they fall. Right now, getting multiple quotes quickly is the best way to gauge current market value.

What Doesn’t Affect Value as Much as You Think

Many sellers overvalue features like custom paint, extra lights, chrome accessories, and premium stereo systems. These things rarely translate into higher offers because most commercial buyers care about mechanical reliability, not aesthetics.

How to Get an Accurate Value for Your Truck

Every factor above moves the number, which is why no online calculator can tell you what your specific truck is worth — the same year and model can be worth thousands apart depending on engine history, condition and title. The only way to get a real figure is to have someone price your actual truck. Use the form above, or call us at (404) 453-1427.
