Quick Answer
A $120,000 truck financed at 9.5% over 60 months costs about $2,500/month. Over the full loan term, you'll pay $30,000+ in interest on top of the purchase price — more than a year of payments for free if you had bought with cash.

What every first-time buyer and experienced operator needs to know before signing
Buying a semi truck is one of the largest financial decisions an owner-operator makes. Get the financing right and your monthly payment becomes a manageable fixed cost that you build equity against. Get it wrong and a high-rate loan can eat your profit margin for years.
Here's what the commercial truck financing market actually looks like in 2026, broken down by lender type and borrower profile.
Credit scores and time in business are the two biggest factors lenders use to set your rate.
Used trucks typically add 1–3% to whatever rate you'd get on a new truck, because lenders treat older equipment as higher collateral risk. A 2019 truck will get a worse rate than a 2023 truck, all else equal.
Traditional banks and credit unions offer the best rates for qualified borrowers. Farm Bureau Financial Services, First Financial Bank, and larger regional credit unions with commercial lending departments are worth calling. The catch: they typically require 2+ years in business, solid credit, and sometimes require a relationship account.
Captive lenders — Daimler Truck Financial (Freightliner), Paccar Financial (Kenworth/Peterbilt), Volvo Financial Services — are the financing arms of truck manufacturers. They often run promotional rates on new trucks (sometimes as low as 3–5% for qualified buyers during promotions) and are easier to qualify for than banks because they're incentivized to move trucks. The tradeoff is that you're typically limited to their brand.
Specialty commercial truck lenders — companies like Commercial Fleet Financing, Currency Capital, and Mission Financial — fill the gap for borrowers who don't qualify at banks. They approve new authority operators, drivers with credit blemishes, and older equipment. The rates are higher (often 15%–25%), but access is easier.
Lease-to-own programs through carriers like Ryder, Penske, or large trucking companies aren't true ownership financing — they're structured as operating leases with a purchase option. Monthly payments are often higher than a loan, and you build no equity during the lease period. These make sense for some situations (new CDL holders with no credit, drivers who want to avoid maintenance responsibility) but are generally not the best financial choice for an experienced operator who plans to run the truck for 5+ years.
The standard requirement is 10%–20% of the purchase price. On a $120,000 used truck, that's $12,000–$24,000.
A 10% down payment gets you in the door at most lenders but results in a higher rate and higher monthly payment. A 20% down payment often unlocks better rate tiers and ensures you're not underwater on the loan from day one (trucks depreciate 15%–20% in the first year of ownership).
If you're short on down payment cash, consider using your existing truck as a trade-in. The trade-in value functions identically to a cash down payment in the lender's calculation. Check current market values on Truck Paper and Commercial Truck Trader before accepting a dealer trade-in offer.
Beyond credit score and time in business, commercial truck lenders look at:

Run the real numbers before you decide — the answer isn't always obvious
The new-vs-used debate is one of the most common questions owner-operators wrestle with. The right choice depends on your financial position, your maintenance skills, and how many miles you plan to put on the truck. Here's how to think through it with real numbers.
A new Class 8 semi truck (Freightliner Cascadia, Kenworth T680, Peterbilt 579) runs $150,000–$185,000 in 2026 depending on configuration. A comparable used 2020 or 2021 model with 400,000–500,000 miles might sell for $80,000–$110,000.
The price difference is significant, but so are the financing cost differences. On a $170,000 new truck at 7.5% APR over 60 months, your monthly payment is approximately $3,400. On a $95,000 used truck at 10.5% APR (used truck premium) over 60 months, your payment is approximately $2,050. That's $1,350/month in payment difference — or $16,200/year.
Use this payment calculator to model both scenarios with your actual numbers.
This is where the new vs. used analysis gets complicated. A new truck under factory warranty (typically 2 years/250,000 miles for the engine and powertrain) has predictable, low maintenance costs. Most new truck owners spend $0.08–$0.12/mile on maintenance in years 1–3.
A used truck with 400,000+ miles is approaching or past major service intervals. Expect:
Experienced owner-operators who can do their own maintenance (or have a trusted shop relationship) often manage used trucks at $0.18–$0.25/mile in total maintenance. Less mechanically inclined operators or those without shop relationships sometimes see $0.30–$0.40/mile on older equipment — erasing the payment savings entirely.
New trucks lose 15%–20% of their value in the first 12–18 months. A $170,000 truck may be worth $135,000–$145,000 after the first year, even with low miles. This rapid initial depreciation means you can easily owe more than the truck is worth (being "underwater") in the first 1–2 years of ownership.
Used trucks depreciate more slowly in dollar terms because they've already taken the steep initial drop. A $95,000 used truck might be worth $80,000–$85,000 after a year if you've maintained it and haven't added too many miles. Less dramatic, but the equity position is often better from the start.
Factory warranties on new trucks are real financial protection. A powertrain warranty on a new Cascadia or T680 covers the engine, transmission, and drivetrain — the most expensive components to repair. If the engine has a major failure in year 1, you're covered. On a used truck, that same failure is your problem.
Extended warranties from dealers on used trucks are available but often have significant exclusions. Read the fine print carefully — many used truck warranties exclude emissions systems (EGR, DPF, SCR), which are among the most problematic components on 2013–2022 EPA-compliant engines.
For a well-capitalized first-time owner-operator with good credit: a 2–3 year old used truck with 200,000–350,000 miles often represents the best value. You get past the steepest depreciation curve, still have meaningful life left on major components, and pay substantially less per month than a new truck purchase.
For an operator with strong maintenance skills or a reliable shop relationship: a 4–6 year old truck with 400,000–600,000 miles can be excellent value if purchased carefully with a pre-buy inspection.
For an operator who wants predictability and can qualify for promotional financing: new is justifiable, especially if captive lender promotions bring the rate down to 3–5%.
Run both scenarios in this calculator. Then run both through the cost per mile calculator to see the full impact on your operating economics.
The math every owner-operator should know before signing a loan
Your monthly truck payment is the largest single fixed cost in most owner-operator budgets. Unlike fuel (which scales with miles driven) or maintenance (which varies), the truck payment is the same whether you run 8,000 miles or 12,000 miles in a month. That makes it your most important number to understand — and the one that most directly controls your break-even rate per mile.
The first calculation every owner-operator should do after getting a truck payment quote is to divide it by their expected monthly miles.
This is why volume matters so much for owner-operators. Running 12,000 miles/month vs. 8,000 miles/month with the same truck payment saves you $0.15/mile in allocated fixed cost. At average spot market rates of $2.00–$2.50/mile, that difference translates to thousands of dollars of annual profit.
Your break-even rate per mile is the minimum you need to charge to cover all costs — including the truck payment — and come out at zero. Anything above break-even is profit.
Here's a realistic example for a dry van owner-operator with a $3,200/month truck payment:
At that cost structure, a driver needs to average at least $1.28/mile just to break even. Current dry van spot rates on most lanes average $1.70–$2.20/mile. That's a workable margin — but it disappears quickly if the truck payment is $4,500+/month or if the driver runs at 7,000 miles instead of 10,000.
The failure pattern for owner-operators with oversized truck payments usually looks like this: driver takes a truck payment they can technically afford in month 1, runs well, then has a slow month due to market softening, weather, or a breakdown. With a high fixed payment, a slow month doesn't mean lower profit — it means negative cash flow.
A truck payment that represents more than 25% of your gross monthly revenue is a warning sign. At $3,500/month payment and $18,000/month gross revenue, you're at about 19% — manageable. At $3,500/month and $12,000/month gross revenue, you're at 29% — tight. Any disruption to revenue creates real cash flow stress.
Two things you control at the time of purchase that have lasting impact on profitability:
Down payment size. A larger down payment directly reduces your monthly obligation. If you have $25,000 saved and are buying a $130,000 truck, putting $25,000 down vs. $13,000 down reduces your 60-month payment by roughly $260/month. That's $15,600 in total payment savings over the life of the loan — and better profitability every single month.
Loan term selection. A 60-month term vs. a 72-month term on a $110,000 principal at 9.5% APR: the 60-month payment is about $2,310/month; the 72-month payment drops to approximately $1,990/month. The $320/month savings sounds attractive, but the 72-month loan costs roughly $4,500 more in total interest. More importantly, a 72-month loan on a used truck means you'll still be making payments when the truck is 6+ years old and potentially in its high-maintenance phase — two financial pressures hitting simultaneously.
Before signing any truck loan, run this check: take your expected monthly payment and divide by your average monthly miles. That's your truck payment cost per mile. Add that to your other operating costs (fuel, insurance, maintenance, permits). Compare the total to what you realistically earn per mile on the lanes you run. If there's a margin of at least $0.40–$0.50/mile above your break-even, the loan is sustainable. If the margin is thinner, either negotiate a better price, put more money down, or walk away.
