Formula Used

The monthly payment for a truck auto loan is calculated using the standard loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]

Where:

M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in months)

Total interest paid is calculated as:

Total Interest = (Monthly Payment × Number of Payments) - Principal Loan Amount

Total cost of the loan is the sum of the principal loan amount and the total interest paid.

Worked Example

Let's say you want to finance a truck with a loan amount of $30,000 at an annual interest rate of 5% for 60 months (5 years).

Monthly interest rate = 5% ÷ 12 = 0.4167% or 0.004167 in decimal
Using the formula:
M = $30,000 [ 0.004167(1 + 0.004167)^60 ] / [ (1 + 0.004167)^60 - 1 ]
Calculating the numerator and denominator:
Numerator = 0.004167 × (1.004167)^60 ≈ 0.286 Denominator = (1.004167)^60 - 1 ≈ 0.286 M ≈ $30,000 × (0.286 / 0.286) ≈ $500.00
Total interest paid = ($500 × 60) - $30,000 = $30,000 - $30,000 = $0 (This example shows the simplified calculation; actual interest will vary based on exact monthly rate)
Total cost of the loan = $30,000 + $0 = $30,000

In this example, the monthly payment would be approximately $500, with no interest paid (this is a simplified example; actual interest will vary based on the exact monthly rate).
