What Is a TRAC Lease, and How Does It Work for Trucks and Trailers?

November 3, 2026 · 7 min read · Equipment Funding Network

A TRAC lease is a lease for trucks, trailers and other titled vehicles used in a business, where a residual value is agreed at the start and settled against the vehicle's real value at the end. TRAC stands for terminal rental adjustment clause: the clause that adjusts the rent at the end of the term. If the truck sells for more than the residual, you get the difference. If it sells for less, you pay the difference. That one feature is what makes a TRAC lease different from every other kind of lease, and it is why you should understand it before you sign one.

Before you sign any lease with a buyout, work through the lease-purchase checklist.

How a TRAC lease works, step by step

You and the lessor agree on the truck, the term and a residual value: what the truck is assumed to be worth at the end.
Your monthly payments cover the difference between the price and that residual, plus the lessor's cost of money. A higher residual means a lower payment.
During the term, the lessor owns the truck and you use it in your business.
At the end, the truck is sold or valued, and the result is compared with the residual.
If the truck brings more than the residual, the extra is credited or paid to you. If it brings less, you pay the shortfall. Many TRAC leases also let you buy the truck for the residual instead.

A worked example

Say a semi tractor costs $150,000 and the TRAC lease sets a residual of $40,000 at the end of the term. These are round example figures, not a quote. Your payments cover the other $110,000 plus the lessor's charges.

The truck sells for $48,000 at the end. That is $8,000 more than the residual, so the $8,000 comes back to you.
The truck sells for $32,000. That is $8,000 less than the residual, so you owe the lessor $8,000.
You want to keep the truck. You buy it for the $40,000 residual, if your lease gives you that option, and it is yours.

The arithmetic is simple. The point is who carries the risk: in a TRAC lease, it is you. If the used truck market is soft when your term ends, or the truck has more miles or more wear than expected, the shortfall is yours to pay.

Who carries the residual risk

This is the clearest way to tell the lease types apart. In a fair market value lease, the lessor carries the residual risk: you can hand the equipment back, and if it is worth less than the lessor hoped, that is the lessor's loss. In a TRAC lease, you carry it, through the adjustment at the end. In a $1 buyout lease or a loan, you own the truck outright at the end, so its value at the end is simply yours, good or bad.

Before you sign, ask the lessor for the residual in dollars, the exact way the truck will be valued or sold at the end, and what you owe if it sells for less. Have all three in writing.

TRAC lease compared with the other options

TRAC lease. Lower payment than a loan, because the residual is not paid down. You carry the risk of the truck's value at the end, and you can usually buy it for the residual.
Fair market value lease. The lessor carries the risk at the end. You can return the truck, renew or buy it at its value then, which nobody knows in advance. Return conditions on miles and wear apply.
Finance lease or $1 buyout. You pay for the whole truck over the term and own it for a dollar at the end. Higher payment, no end-of-term surprise.
Loan or equipment finance agreement. You own the truck from the start, the lender holds a lien on the title, and you pay it down to zero.

When a TRAC lease fits

Fleets that replace trucks on a regular cycle and want a lower payment while they run them.
Owners who know the used market for their make and model and are comfortable with the residual set.
Businesses whose CPA has looked at the lease and sees a benefit in how it is treated for taxes.

When a loan is simpler

You plan to run the truck until it wears out. A loan pays it off, and there is nothing to settle at the end.
You put on heavy miles. The more wear, the more likely the truck sells below the residual.
You cannot afford a surprise bill at the end of the term. With a loan, the last payment is the last payment.

Taxes and your accountant

TRAC leases exist because of a federal tax rule for vehicles leased to businesses, and they are often written so that the lessor, not you, is the owner for tax purposes. That generally means the payments are treated as rent rather than as a purchase, which changes what you deduct and when. Whether that helps your business, and how your particular lease is treated, is a question for your CPA. This guide is not tax advice.

Where EFN fits

EFN is not a lender, and it does not approve or fund deals. You describe the equipment and the business in one short application, and the first step is a soft credit pull that does not affect your score. Tell us whether you want to own the truck at the end or keep the payment low, and the file goes to a lender that writes the kind of deal you asked for. A person reviews every file before it goes to a lender, and it goes to one lender at a time, not out to a list. If nothing fits, we tell you so. EFN's service is free to you.

Common follow-up questions

What does TRAC lease stand for?
TRAC stands for terminal rental adjustment clause, the clause that settles the vehicle's real value at the end of the lease against the residual agreed at the start.

Is a TRAC lease a good idea?
It can be for a fleet that replaces trucks on a cycle and wants a lower payment. It carries a risk a loan does not: if the truck sells for less than the residual, you pay the difference.

What happens at the end of a TRAC lease?
The truck is sold or valued and compared with the residual. If it brings more, you get the difference; if less, you pay it. Many TRAC leases also let you buy the truck for the residual.

What is the difference between a TRAC lease and an FMV lease?
In an FMV lease the lessor carries the risk of the truck's value at the end and you can hand it back. In a TRAC lease you carry that risk through the adjustment at the end.

Can I use a TRAC lease for equipment that is not a vehicle?
Generally no. TRAC leases are for titled vehicles and trailers used in a business, such as trucks and tractors. Machinery is usually leased or financed in other ways.
