Formula Explained

This calculator uses the standard auto loan payment formula:

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

Where:

P = Principal loan amount (loan amount - down payment)
r = Monthly interest rate (APR/12/100)
n = Number of payments (loan term in years × 12)

The calculator also calculates total interest paid by multiplying the monthly payment by the number of payments and subtracting the principal loan amount.

Worked Example

Let's calculate a $25,000 auto loan with a 1.9% APR over 5 years:

Principal = $25,000
Monthly interest rate = 1.9%/12 = 0.001583
Number of payments = 5 × 12 = 60
Monthly payment = $25,000 × (0.001583(1 + 0.001583)^60) / ((1 + 0.001583)^60 - 1) ≈ $463.50
Total interest paid = ($463.50 × 60) - $25,000 ≈ $1,086.00

This example shows you would pay approximately $463.50 per month with a total interest cost of $1,086 over the life of the loan.

Frequently Asked Questions

How does down payment affect my monthly payment?

A larger down payment reduces your principal loan amount, which typically results in lower monthly payments. However, the exact impact depends on your loan term and interest rate.
