How much does a semi truck cost?

Work out what a semi truck actually costs to put on the road, and then what it costs per mile of the life you are buying. Put in the seller's price, the pre-purchase inspection, the tires and repairs it needs to be road-ready, the plates and your sales tax, and see the out-the-door total, what the sticker left out, and the total divided by the miles you plan to run. A used truck and a new one only compare on that last figure.

§ 01 Your numbers

Change anything. The answer updates as you type.

The headline figure for the tractor unit on its own. The default is ours and editable, and the seller's figure is the one that matters.
More
Pin down what is inside this number before you compare it with another one. The odometer is the obvious thing and it is not the whole story: a truck's price moves on the engine and who will work on it, the transmission, whether it is a day cab or a sleeper, the axle configuration, and what the aftertreatment has been through. Ask for the service records and the ECM report rather than trusting the dash, and get the spec written down beside the price, because two trucks a few thousand apart are frequently two different purchases.
An independent truck shop putting the truck on a lift before you buy it. The smallest box on this page, and the one that decides the next box.
More
This is the line the page argues hardest for. You are not paying for an opinion, you are paying to convert the road-ready figure below from a guess into a quote. A shop that is not selling you the truck will pull codes, read the ECM, measure the brakes and the tires, look at the frame and the fifth wheel, and tell you what the aftertreatment has been doing. That either confirms the discount you are being offered or explains it. Buying a truck without it is buying the odometer and hoping the rest came with it.
What the truck needs before it earns anything: tires, brakes, the DOT annual inspection, and whatever the pre-purchase inspection finds. The default is ours and editable.
More
A truck rolls on ten wheels and a set of tires is a four-figure line that no sticker mentions. Beside that sit the brakes, the DOT annual it needs to run legally, and the deferred maintenance the last owner decided was the next owner's problem. This is the box with the widest spread on the page: on an inspected truck with records it is tires and an annual, and on a cheap truck with a story it can pass the discount that made it look cheap. Fill this in from the inspection rather than from hope.
Getting it titled and legal to run: registration, apportioned plates if you cross state lines, and the paperwork around them. Ours, a placeholder, and editable.
More
What this costs turns on where the truck is based, how much it weighs, and which states you will actually run in, so it is your number rather than ours. If you are running interstate this is apportioned registration rather than a plate at a counter, and it is worth asking someone who does it in your state what the real figure looks like before you budget ours. There are federal taxes and filings that attach to a heavy truck as well, and they are a question for your accountant rather than for this page, which does the arithmetic on whatever you type.
Zero by default on purpose. A semi truck is the tractor unit, and many owner-operators pull a trailer the carrier provides.
More
The word semi hides a split worth being clear about: the thing people price is the tractor, and the thing that hauls freight is a tractor and a trailer. Which side of the line the trailer sits on depends on how you are running. Pulling for a carrier that drops trailers, this box stays at zero and the truck is the purchase. Running under your own authority, the trailer is a real second purchase, and a dry van, a reefer and a flatbed are three different numbers for three different kinds of work. Put your figure in and the total will carry it.
Your own rate, because we do not know where you are buying. Leave it at zero to see the pre-tax bundle.
More
On a purchase this size the tax is not a rounding line, which is why it has a box rather than a shrug. How it lands is genuinely local: it turns on where the truck is registered rather than where the lot is, and states treat a truck bought for a business differently from the same truck bought by a person. If the machine is going into a company, how the purchase is written down against your income is a separate question again. This page does the arithmetic on whatever rate you put in it and leaves both of those to the people who can answer them.
The denominator, and the reason this page exists. Our default is a placeholder: yours is the number that decides whether a truck is cheap.
More
This is the box people leave out of the comparison, and it is the one doing the ranking. A cheap truck is not selling you a truck, it is selling you the miles left in it before the engine, the aftertreatment or you decide it is finished. A dearer truck with a fresh engine is selling more of them. Neither sticker mentions the difference, so the division below is where it shows up. Be honest here rather than optimistic: use the miles you will genuinely run it for, at your real annual mileage, until the point you would sell it or pay for an overhaul.

$30,000 to $90,000 is the ordinary shape of this purchase: a used tractor with the tires, the annual and the plates behind it. Compare this against your other trucks on the cost-per-mile figure above rather than on the two stickers, since that is the comparison that keeps the remaining miles in the frame.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

A STICKER CANNOT RANK TWO TRUCKS, BECAUSE THEY ARE NOT SELLING THE SAME THING.
This is the whole page. A used truck sells a low price and a short remainder. A new truck sells a high price and a long one. Compare the two stickers and you have compared the numerators and thrown the denominator away, which is why a cheap truck can be the dear one and the sticker will never say so. Divide the out-the-door total by the miles you will genuinely run before you sell it or pay for an overhaul, and the two become comparable. At our defaults that is $51,500 over 400,000 miles, or about 13 cents a mile. The page does not tell you which way your two trucks land, because you type both halves and the ranking turns on them.
The smallest box on the page decides the largest one.
The pre-purchase inspection is $500 of our default money and it is the line worth arguing for, because it is what turns the road-ready figure from a guess into a quote. An independent shop that has no truck to sell you will read the ECM, pull the codes, measure the brakes and the tires, look at the frame and the fifth wheel, and tell you what the aftertreatment has been doing. It either confirms the discount you are being offered or explains it. Skip it and you have not saved $500, you have bought the odometer and agreed to whatever is behind it, unpriced.
A semi truck is the tractor, and freight needs a trailer.
The word hides a split. What gets priced when people ask what a semi costs is the tractor unit, and what moves a load is a tractor and a trailer. Which side of your purchase the trailer falls on is a real question rather than a detail: pulling for a carrier that provides trailers, the trailer box here stays at zero and the truck is the whole purchase. Running under your own authority, it is a second purchase in its own right, and a dry van, a reefer and a flatbed price three different kinds of work. The box is here and it starts at zero, so the total follows your answer rather than assuming one.

Tires are a four-figure line that no sticker mentions. A tractor rolls on ten wheels, and a set is real money on a truck of any price, which is why the road-ready box sits beside the sticker rather than inside it. Around it sit the brakes, the DOT annual the truck needs to run legally, and the maintenance the last owner left for the next one. On an inspected truck with records this box is tires and an annual. On a cheap truck with a story it can swallow the discount that made it look cheap, and the inspection above is how you find out which one you are looking at.

What you write the check for is not what the truck costs you. A truck bought is a truck fuelled, insured, plated, serviced, parked and losing value while it sits, and this page prices none of that, because it is answering the question people type: what does one cost to buy. The operating cost calculator adds fuel, maintenance and the value it loses per working hour, and if you are pricing the whole business rather than the machine, the trucking company startup calculator adds authority, insurance and the working capital to get to the first settlement. This page stops at the yard gate on purpose.

Frequently asked questions

How much does a semi truck cost?
It depends on the truck, and then on four things quoted separately that are part of the same purchase: the pre-purchase inspection, the tires and repairs it needs to be road-ready, the plates and title, and your sales tax. A seller sets the price privately against an odometer, an engine and a spec, so this page leaves the figure to your seller rather than inventing one to stand in for it. Put the real numbers into the form above and the calculator gives you the out-the-door total, what the sticker left out, and the total divided by the miles you plan to run. That last figure is the one worth carrying to the next truck, because two stickers are not comparable and two cost-per-mile figures are.
Is a used semi truck cheaper than a new one?
The purchase is, and the purchase is the part of the question a sticker answers. Whether the truck is cheaper is a different question, and it turns on the box most people leave out: how many miles are left in it before you sell it or pay for an overhaul. A used truck sells a low price and a short remainder, a new one sells a high price and a long remainder, and the stickers compare the prices while hiding the remainders. Price both bundles above with the miles you would genuinely run each one, compare the cost-per-mile figures rather than the two prices, and then decide on the things this page cannot see: the warranty, the service records, who will work on that engine, and what the financing offer is worth.
What does a semi truck cost beyond the sticker?
At our defaults the sticker is $45,000 and the out-the-door total is $51,500, so $6,500 of the check is sitting outside the price you were quoted, before any sales tax or trailer. That is the inspection, the tires and the annual to make it road-ready, and the plates and title. Those are not accessories bolted onto the purchase, they are conditions of the truck turning a wheel legally and earning anything, which is why they are lines here rather than a footnote. Your figures will differ from ours and every box above is editable, which is the point: the gap is the thing to measure, not to guess at.
Do I need a trailer as well as the truck?
It depends how you are running, and it is worth settling before you budget, because it moves the number a lot. A semi truck is the tractor unit. If you are pulling for a carrier that drops trailers for you, the truck is the whole purchase and the trailer box above stays at zero. If you are running under your own authority, hauling freight needs a trailer of your own, and it is a second purchase rather than an add-on: a dry van, a reefer and a flatbed are different machines for different work at different prices. Put your figure in the trailer box and the total and the cost-per-mile will both carry it.
