How the payment is calculated
Amount financed = price × (1 + tax %) − down payment − trade-in Monthly payment = A × r ÷ (1 − (1 + r)^−n) r = APR ÷ 12, n = months Cost per mile = monthly payment ÷ miles per month
Before you sign
- Keep the truck payment under about $0.25–$0.30 per mile you expect to run.
- Ask about balloon payments and prepayment penalties.
- Budget a repair reserve for a used truck. Out-of-warranty engine work can cost $20,000+.
Common questions
What credit score do I need for a semi truck loan?
Lenders vary, but many want 600–650+ for standard rates. Lower scores can still get financing with a larger down payment and a higher rate.
How much down payment for a semi truck?
Typically 10–25%, more for new owner-operators or older trucks.
Is lease-purchase better than a loan?
Usually not. Many lease-purchase deals cost more over time and you build no equity if you leave early. Compare total cost.
