Semi truck value estimator
There's no free official price book for used semi trucks, so this estimator works from real listings you find. Enter your truck's year, miles and condition, then two or three similar trucks for sale. The worksheet adjusts each listing to match your truck and shows a low, middle and high value range, with every assumption visible and editable.

Each listing is adjusted: + 6% of its price per newer model year, + $400 per 10,000 fewer miles, then +0% for condition. Listings are asking prices, not sale prices.

How the estimator works
A value worksheet copies how buyers and sellers really price trucks: by comparing them with similar trucks for sale.
- Your truck. Enter the model year, miles, a condition grade and the class.
- Comparable listings. Enter the year, miles and asking price of up to three similar trucks you found for sale. Set a price to 0 to skip a slot.
- Adjust each listing to your truck. For every model year your truck is newer, the listing's price goes up by the year adjustment, and down for every year older. For every 10,000 miles fewer than the listing, the price goes up by the miles adjustment, and down for more miles.
- Apply condition. Excellent adds 8%, good adds 3%, average adds nothing and rough takes off 12%.
- Range. The lowest and highest adjusted listings set the range. The middle is their average.
The adjustment amounts are starting assumptions, not market data. Open them and change them if your market values miles or age differently.
A worked example
An owner has a 2019 tractor with 520,000 miles in average condition. They find three listings: a 2019 with 480,000 miles at $62,000, a 2020 with 550,000 miles at $68,000 and a 2018 with 600,000 miles at $54,000.
- 2019, 480,000 mi: 40,000 more miles on ours
- $60,400
- 2020, 550,000 mi: one year older, fewer miles
- $65,120
- 2018, 600,000 mi: one year newer, fewer miles
- $60,440
- Range
- $60,400 to $65,100
- Middle of the range
- about $62,000
Adjustments used: 6% per model year and $400 per 10,000 miles.
The range is fairly tight because the listings are close to the owner's truck. Wider gaps between listings mean less certainty, and a sign to look for closer comparisons.
What the result means
The range is an estimate of asking prices for a truck like yours, not a book value, an appraisal or an offer. Expect real sales to land below asking prices. A dealer trade-in usually pays less again, because the dealer has to recondition and resell the truck.
Things the worksheet can't see: engine and transmission model, sleeper size, emissions history, warranty left, tire and brake life, accident history and how much buyers in your region want your spec. Each can move value more than the adjustments do. Our guide to the most reliable semi trucks explains how to judge a truck's track record without brand hype.
Getting a better price
- Gather records. Maintenance invoices, recent repairs and inspection reports show a buyer the truck was cared for.
- Fix the small things. Lights, leaks and worn interior parts cost little to fix and a lot in negotiation.
- Price for your market. Use listings from your region where you can.
- Know your payoff. If the truck is financed, check what you owe before you set a price.

When to get a professional opinion
A worksheet is fine for setting an asking price or deciding whether to sell. Some situations call for more. Lenders, insurers, courts and buyers of whole fleets often want a written appraisal from a qualified equipment appraiser, and a dealer's written trade offer is the only number you can actually take to the bank on a trade.
It's also worth paying for a pre-sale inspection on a high-mileage truck. An inspection report gives buyers confidence, answers questions before they're asked and can stop a deal from falling apart at the last minute over a surprise. If the inspection finds a problem, you can fix it or price it in, instead of losing the buyer.
Selling, trading or keeping?
Before selling, it's worth asking whether the truck could earn more by working steadier. A truck that sits between loads costs the same each month as one that runs. If you came into the truck through a lease, our page on lease-purchase dispatch explains how we help those drivers keep the truck moving. Want to know what dispatch would cost on your gross?

Questions about this tool
CH 01How much is my semi truck worth?
It's worth what a buyer will pay for a similar truck in your market right now. The best guide is recent listings and sales of trucks like yours: same make and model range, similar year, miles, engine and specs. This estimator adjusts those listings to your truck's year, miles and condition, so you get a range instead of a guess.
CH 02Where can I find comparable semi truck listings?
Look at the big online truck marketplaces, dealer websites and auction results, and filter by make, model, year range and engine. Pick listings as close to your truck as you can, ideally in your region. Note each one's year, miles and asking price. Three good comparisons beat ten loose ones.
CH 03Do miles or age matter more for truck value?
Both matter, and so does how the truck was cared for. High miles mean more wear on the engine and drivetrain, while age brings older emissions equipment and features. Documented maintenance and a recent major repair can outweigh a few extra miles. Adjust the assumptions in the calculator if your market treats miles or age differently.
CH 04Why are listing prices higher than what trucks sell for?
Listings are asking prices, and most sellers leave room to negotiate. Dealers also price in reconditioning, warranty and their margin. A private sale often lands below a dealer's asking price for the same truck. Treat the middle of your range as a starting point and expect offers below it.
CH 05What raises a used semi truck's value?
Complete maintenance records, a clean title, recent work on the engine, aftertreatment or transmission, good tires and brakes, a clean interior and specs buyers want in your area. Fixing small problems before listing also helps, because buyers knock more off for visible issues than the repairs usually cost.
Keeping the truck? Keep it loaded.
A truck that runs steady pays its own note. We find the loads and work the rates, and every load waits for your yes.
