How do I calculate a monthly truck payment?

A fixed-rate loan payment is the loan amount times the monthly interest rate. Divide that by one minus (one plus the monthly rate) raised to the power of minus the number of months. The loan amount is the truck's price plus tax and fees, minus the down payment and any trade-in value.

  1. Monthly rate = annual interest rate / 12.
  2. Loan amount = price + sales tax + title fees - down payment - trade-in value.
  3. Payment = loan amount x monthly rate / (1 - (1 + monthly rate) ^ -months).
  4. Example: a $100,000 loan at 9% over 60 months is about $2,075.84 a month. About $24,550 of the total paid is interest.

The payment is for a fixed rate and equal monthly payments. Your lender's quote can differ because of fees, the way interest is figured and any balloon or prepayment terms, so use it as a starting point and compare real quotes. The miles figure shows how many miles it takes to earn the payment alone at the revenue per mile you enter. Fuel, insurance and every other cost come on top.

Frequently Asked Questions - Truck Payment Calculator

What's a typical down payment for a semi-truck loan?
Lenders commonly ask for 10 to 20 percent down, though the exact requirement depends heavily on your credit, time in business and whether the truck is new or used. A larger down payment lowers both your monthly payment and the total interest you pay over the loan.
What are current interest rates for semi-truck loans?
Rates vary significantly by credit profile and time in business: strong credit with an established business commonly sees meaningfully lower rates than a new authority with limited credit history, which can see rates well into the high teens or beyond. Shop multiple lenders and compare your actual quoted rate, since published 'typical' ranges can be wide and quickly outdated.
How long should I finance a semi-truck?
New trucks are commonly financed over 3 to 5 years; used trucks over shorter terms, often 2 to 4 years. A shorter term means a higher monthly payment but less total interest. Avoid financing longer than the truck's realistic useful life for your operation, to reduce the risk of owing more than the truck is worth later in the loan.
Should I lease or buy a semi-truck?
Buying builds equity in the truck and is often cheaper over the long run if you keep it for years. Leasing typically has a lower monthly payment and may include maintenance, but builds no equity and can carry mileage limits. If you plan to keep a truck 5 or more years, buying is usually the stronger financial choice; if you want to cycle into newer trucks more often, leasing can make more sense.
How do I calculate a monthly truck payment?
For a fixed-rate loan, the monthly payment is the loan amount times the monthly interest rate, divided by one minus (one plus the monthly rate) raised to the power of negative the number of months. A $100,000 loan at 9 percent over 60 months works out to about $2,076 a month. The calculator does this math for any amount, rate and term you enter.
How much does paying extra each month save?
Extra money goes straight to the loan balance, so you owe less interest every month after that. Enter an amount in the calculator and it shows the month the loan is paid off and the interest saved. Ask your lender first whether the loan has a prepayment penalty, and check that extra payments go to the principal.
What does 'miles to cover the payment' mean?
It is the payment divided by your revenue per mile: how many miles it takes to earn the truck payment alone. It is not a break-even for the whole truck. Fuel, insurance, maintenance and every other cost come on top, so use the Cost Per Mile Calculator for the full picture.
