The loan math
where r = APR ÷ 12, n = months, loan = price − down
Truck financing runs on the same amortization math as any loan, but the rates are steeper — equipment lenders price for the risk of the business, not just your credit. A $70,000 loan at 12% over 48 months costs about $18,500 in interest; the same loan at 20% costs over $32,000. That difference is a year of fuel.
Watch the term trap: stretching to 72 months shrinks the payment but you'll likely still owe money when the truck is out of warranty and living at the shop. Feed the payment into your cost per mile — a payment that looks fine on paper can push your break-even above what your lanes pay.
FAQ
What APR should I expect on a truck loan?
Established owner-ops with good credit: often 7–12%. New authority or bruised credit: 15–25%+ from equipment finance companies. Get the APR in writing — the payment alone hides it.
How much down do lenders want?
Usually 10–30% on a used Class 8. More down = smaller loan and less time upside-down on a fast-depreciating asset.
Longer term for a lower payment — worth it?
The payment drops but total interest climbs, and you risk owing on a truck that's out of warranty. Match the term to the truck's realistic remaining life.
