60 months at 12% APR
Every 1% of APR moves this payment by about $64/month - which is why comparing lenders matters.

How the semi truck payment is calculated
The calculator uses the same fixed-rate amortization formula truck lenders use: the price minus your down payment is financed over the term at your APR, and the monthly payment covers both principal and interest.
Put anything you'll finance with the truck - an APU, an extended warranty - into the price. Budget separately for registration (IRP), the heavy vehicle use tax (Form 2290), and insurance, which lenders will expect you to carry from day one.
New vs. used semi truck financing
Typical structures by truck age (exact terms vary by lender and credit):
| New tractor | Used (3-6 years) | Older (7+ years) | |
|---|---|---|---|
| Typical price | $150K - $200K+ | $60K - $110K | $25K - $60K |
| Typical term | 60-84 months | 36-60 months | 24-48 months |
| Down payment | 0-10% | 10-20% | 15-30% |
| Rate profile | Lowest | Moderate | Highest |
Payment vs. revenue: the number lenders watch
Lenders care less about the payment on its own than about whether the truck's gross comfortably covers it along with fuel, insurance and maintenance - which together take far more than the note. Enter the truck's expected monthly gross to see the payment as a share of revenue.
If the share looks tight, the levers are the same ones in the next section: more down, a late-model used truck, or a longer term while the truck has the life for it.
Ways to lower your truck payment
- Put 10% down - on an $80K truck that's $8,000, but it cuts the payment and moves you into a better rate tier.
- Look at late-model used trucks: a 3-5 year old tractor often costs half of new with plenty of useful life left.
- Stretch the term only within the truck's useful life - check total interest, not just the payment.
- Make 12 months of on-time payments, then refinance - rates often drop meaningfully once you've proven the payment history.
- Use freight factoring to smooth cash flow, so slow-paying brokers never make you late on the truck.

Apply NowMany commercial truck programs start around 600, and some work below that with a larger down payment. Above 680 you'll see more lenders and better rates; under 620, expect 20-30% down and a higher APR.
Roughly 0-10% for strong credit and established carriers, 10-20% for most first-truck buyers, and 20-30% for challenged credit or older trucks.
Yes. New authorities can finance, typically with more down and a closer look at personal credit, CDL experience and the contracts or loads you have lined up.
Usually 36-72 months. New trucks can stretch to 84 months with some lenders, while older trucks get shorter terms tied to their remaining useful life.
No - it's an estimate. Your real rate, term and down payment depend on the lender, your credit, your operating history and the truck itself.
