Short Answer
A truck loan is only affordable if the truck earns more than it costs to run plus the payment. This calculator puts the three numbers together — the loan payment, the current spot rate per mile (from DAT), and the operating cost per mile (from ATRI) — so you can see your monthly net and the miles you need to break even before you sign.
Can you afford the truck payment?
Most loan calculators stop at the monthly payment. That number is meaningless without the revenue side. A $2,000 payment is easy on a lane paying $2.75/mile and impossible on one paying $1.90. This tool models both — it's the check to run before you fall in love with a truck.
How it works
- → Gross = your miles/month × the spot rate for your freight type.
- → Operating cost = miles × cost/mile (fuel, maintenance, insurance, tolls) — excluding the truck payment so it isn't double-counted.
- → Net = gross − operating cost − loan payment. Positive means the truck covers itself.
- → Break-even miles = the miles you must run just to cover the payment after costs.
Where the default numbers come from
Every field is editable, but the starting values are real, sourced figures — not guesses:
- Spot rates — DAT national averages (early 2026): dry van ~$2.36, reefer ~$2.75, flatbed ~$2.70/mile. These move every month, so check the live figure at DAT Trendlines.
- Operating cost — the American Transportation Research Institute (ATRI) put the 2024 average at $2.26/mile, which already includes about $0.39/mile in truck & trailer payments. We default the operating-cost field to $1.87/mile (that $2.26 minus the $0.39 payment) so the loan payment you enter isn't counted twice. Source: ATRI Operational Costs of Trucking.
Once the numbers work, see how rates are set by credit, run the plain payment calculator, and read why regulators warn against lease-purchase deals as an alternative to a loan.
Can You Afford the Payment?
Truck price + rate vs. today's spot rates and real operating costs
At 10,000 mi/mo and $2.36/mi, this truck covers its payment with a cushion.
Estimates only, not a quote. Spot-rate defaults are DAT national averages (early 2026) and move monthly — check the current figure at DAT Trendlines. Operating-cost default ($1.87/mi) is ATRI's 2024 average of $2.26/mi minus ~$0.39/mi truck & trailer payments (excluded here so the loan payment isn't double-counted) — see ATRI.
