Formula Explained

The auto loan calculator uses the standard loan payment formula to calculate your monthly payments:

Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1)

Where:

P = Principal loan amount (loan amount - down payment)
r = Monthly interest rate (annual rate / 12 / 100)
n = Number of payments (66 months)

This formula accounts for the interest you'll pay over the life of the loan and provides an accurate estimate of your monthly payments.

Worked Example

Let's look at an example to see how the calculator works. Suppose you're considering a $25,000 auto loan with a 5.5% annual interest rate and a $2,000 down payment.

Principal amount = $25,000 - $2,000 = $23,000
Monthly interest rate = 5.5% / 12 / 100 ≈ 0.004583
Number of payments = 66
Plugging these values into the formula: Monthly Payment ≈ $23,000 * (0.004583(1+0.004583)^66) / ((1+0.004583)^66 - 1) ≈ $425.32

Using our calculator, you would enter $25,000 as the loan amount, 5.5 as the interest rate, and $2,000 as the down payment. The calculator would then display a monthly payment of approximately $425.32.
