How to Use This Calculator

To calculate your auto loan payments:

Enter the loan amount in dollars (e.g., 25000)
Enter the annual interest rate (e.g., 5.25)
Select the loan term in years (e.g., 5)
Click "Calculate" to see your monthly payment and total interest

The calculator uses the standard amortization formula to determine your monthly payments. You can also view a breakdown of your loan payments over time.

Formula Used

The monthly payment (P) for an auto loan is calculated using the following formula:

P = (L × r × (1 + r)^n) / ((1 + r)^n - 1) Where: L = Loan amount r = Monthly interest rate (annual rate / 12 / 100) n = Number of payments (loan term in years × 12)

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

Worked Example

Let's calculate a $25,000 auto loan at 5.25% annual interest for 5 years:

Input	Value
Loan Amount	$25,000
Annual Interest Rate	5.25%
Loan Term	5 years

Using the formula:

r = 5.25% / 12 / 100 = 0.004375 n = 5 × 12 = 60 P = (25000 × 0.004375 × (1 + 0.004375)^60) / ((1 + 0.004375)^60 - 1) P ≈ $452.38

Your monthly payment would be approximately $452.38, with a total interest cost of about $2,784.40 over the life of the loan.
