Semi Truck Loan Calculator
Calculate the monthly payment on a semi truck or commercial tractor loan. Owner-operators and small fleets use these to estimate the payment before financing through a commercial lender.
For reference, the U.S. Prime Rate is currently 6.75% (source: Federal Reserve H.15, as of 2026-08-13). Lenders price semi truck loans as Prime plus a margin set by your credit and term, so the rate you are quoted will usually sit above this. Enter the actual rate a lender offered. This benchmark is context only and never enters the calculation.

semi truck loan questions
Can a new owner-operator finance a semi?
Yes, though startup operators face higher rates and larger down payments. Time in business and a clean MVR/DOT record improve terms.
How this estimate is built
The model
Figures assume a fixed rate and equal monthly payments; sales tax and trade-in are optional and adjust the financed amount. Some semi truck loans use balloon, seasonal or simple-interest structures this tool doesn’t model. The interest rate is the one you enter from your lender, not a figure we set. Confirm any offer with the lender.
Not a lender
