Semi Truck Financing
A Class 8 tractor is usually the biggest purchase an owner-operator ever makes, and lenders treat the deal that way. Semi truck financing is its own category because the collateral is easy to understand: auction values get published every week, the odometer tells most of the story, and a deep used-truck market means a lender can recover its money fast if a loan goes bad. That resale liquidity is why semis sit at the friendly end of the equipment financing rate spectrum.
What lenders look at on a semi truck
Credit tier comes first. Lenders sort buyers into four tiers, from Tier 1 (FICO 740 and up) down to Tier 4 (below 620), and the tier sets your base rate. After that they look at the truck itself: model year, mileage, maintenance records, and whether the engine has had a major overhaul. A well-documented truck with 400,000 miles often finances easier than a neglected one with 250,000.
If you run under your own authority, expect questions about how long you have had it and what your work pipeline looks like. A signed contract or a steady lane history carries real weight with the underwriter.
Semi truck financing rates by credit tier
The calculator on this site uses 2026 market data from independent lenders. On a 36-month term, a Tier 1 buyer financing a truck up to 3 years old lands around 8.9% APR. The same buyer on a 4-to-7-year-old truck pays about 10.9%, and 12.9% on a rig 8 years or older. Tier 2 runs 11.5% to 15.5%, Tier 3 runs 15% to 20%, and Tier 4 buyers are looking at 22% to 28% depending on truck age.
Term length moves the number too. Stretching to 60 months adds 0.6 points for Tier 1 and 1.5 points for Tier 4. A 72-month term adds up to 2.25 points for challenged credit.
Down payments, terms, and structures
Expect 10% to 20% down on a semi, with strong credit at the low end and older trucks pushing higher. Terms run 24 to 72 months, and the calculator defaults to a 25% residual when you model a TRAC lease, the tax-advantaged structure built for vehicles over 10,000 pounds. A plain equipment loan keeps things simple if you want the title free and clear at the end.
Financing structures worth a look
- TRAC lease: lower monthly payments via a set residual, built for vehicles over 10,000 lbs
- equipment loan: fixed payments and full ownership from day one
Semi truck financing FAQ
How much down payment do I need for semi truck financing?
Most lenders want 10% to 20% down. Tier 1 credit on a newer truck can land near 10%, while older trucks or challenged credit can push the requirement to 25% or more.
What credit score do I need to finance a semi truck?
Financing exists at every tier. Tier 1 starts at a 740 FICO and earns rates around 8.9% on newer trucks. Tier 4 covers scores below 620, where rates run 22% to 28% and down payments get larger.
Can I finance a semi truck with high mileage?
Yes, but expect the truck to price in the 8-years-or-older bracket, 12.9% to 28% APR depending on your tier, with a shorter term and a bigger down payment. Maintenance records matter a lot here.
Is a TRAC lease or a loan better for a semi truck?
A TRAC lease lowers the monthly payment by parking a set residual at the end, and the payments are generally tax deductible. A loan costs more per month but you own the truck outright. Ask your accountant which fits your tax picture.
