Semi Truck Financing: The Complete Guide
What actually determines your rate, your down payment, and whether you qualify at all.
Semi Truck Financing
Rate depends on more than your credit score
Time in business, down payment size, the truck's age, and whether you're financing through a bank, a captive lender, or an online lender all move the rate as much as your credit does.
A secured loan changes the credit conversation
Because the truck itself secures the loan, truck financing is often more accessible with a weaker credit file than an unsecured business loan would be, though it still affects your rate.
Online lenders move fast, traditional banks move cheap
Online and alternative lenders typically approve and fund faster but charge more; banks and credit unions are slower and stricter but usually cheaper if you qualify.

Semi truck financing is a secured loan against the truck itself, which is exactly why it's often available to carriers who'd struggle to get an unsecured business loan. The tradeoffs between lender types matter more than any single advertised rate.
What Actually Sets Your Rate
Lenders price truck loans off a mix of your credit profile, time running your own authority, the size of your down payment, and the age and type of the truck. A newer truck with a bigger down payment from a carrier with two years of clean authority gets a materially different offer than a new authority financing an older truck with nothing down.
Bank, Captive Lender, or Online Lender
Banks and credit unions tend to offer the lowest rates but the strictest qualification bar. Captive lenders (tied to a specific truck manufacturer or dealer) often move faster and sometimes run promotional rates on new inventory. Online and alternative lenders approve the widest range of credit profiles but charge the most for that flexibility.
What a Down Payment Actually Buys You
Most lenders want 10 to 20 percent down, though some advertise zero-down programs (see our zero down financing guide for what that actually costs). A bigger down payment lowers your rate, your monthly payment, and your risk of owing more than the truck is worth if you need to sell it early.
Running the Numbers Before You Sign
Any financing offer should be run through the Semi-Truck Payment Calculator against your real expected revenue, not just compared to the previous month's payment on an older truck. A lower rate on a bigger loan can still mean a payment that doesn't fit your freight.
