FAQ

How is the monthly payment calculated?

Standard amortization: M = P × r × (1+r)^n / ((1+r)^n − 1), where P = loan amount, r = monthly rate (APR ÷ 12), n = number of months.

Does this include taxes, registration, and fees?

No. Roll those into the loan amount or pay separately. Our calculator computes principal + interest only.

What APR should I assume?

Prime borrowers (FICO 700+, 1+ years operating): 7%–11%. Mid-tier: 11%–18%. Sub-prime / new MC / bad credit: 18%–28%. Use the midpoint of your tier as the input.

What term should I pick?

60 months is standard. 72 months on newer trucks. 36–48 months on older units (>500k miles) because lenders cap term by truck age.

Is there a prepayment penalty?

Many trucking equipment loans have NO prepayment penalty. Some short-term advance products do. Always confirm before signing.

Should I include the down payment in the loan amount?

No. The amount field should be the FINANCED amount (truck price minus down payment minus trade-in).

Does this account for insurance financing?

No — insurance premium financing is a separate product. Use the cost-per-mile calculator to model your full carrying cost.
