What this calculator does

Calculate monthly truck or trailer payment, total interest, and total cost of ownership.

Definition
Truck Payment — Truck payment is the monthly principal-and-interest amount on a commercial truck loan, calculated via standard amortization.

Why it matters

Owner-operators and fleet managers across the United States — from Texas and California freight lanes to the Midwest and Southeast — rely on the truck payment numbers to price loads, negotiate with brokers, and protect margin. Getting this figure right is the difference between a profitable week and a break-even one, and it's the same math our dispatchers run on every load we book.

Methodology

This calculator uses the industry-standard formula shown below. Inputs and defaults are based on Bonafide's day-to-day dispatch operations across U.S. carriers, cross-checked against FMCSA guidance and DAT/Truckstop market data. Results render as plain text (not canvas or images) so they're readable by screen readers, search engines, and AI assistants.

FAQ

What APR can I expect on a truck loan?

Strong credit gets 8–10% on used Class 8 in 2026. Sub-prime credit can hit 16–20%.

How much should I put down?

10–15% down is standard. Less than 5% triggers higher APR and often a balloon.
