How to Use This Calculator

Enter the loan amount, interest rate, and loan term to calculate your monthly payments. The calculator will show you the total interest paid over the life of the loan and provide a breakdown of your payments.

For Arizona residents, the calculator uses the state's average interest rates and assumes a standard 4-year loan term unless you specify otherwise. You can adjust these values to match your specific loan conditions.

Formula Used

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

Total interest paid is calculated by subtracting the original loan amount from the total of all payments made.

Worked Example

Let's calculate a loan for $25,000 at 4.5% annual interest over 5 years (60 months):

1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375 in decimal
2. Plug values into formula: 25,000 × (0.00375 × (1.00375)^60) / ((1.00375)^60 - 1)
3. Calculate monthly payment: $475.23
4. Total paid over 5 years: $475.23 × 60 = $28,513.80
5. Total interest paid: $28,513.80 - $25,000 = $3,513.80

This example shows that over 5 years, you would pay $475.23 per month with $3,513.80 going to interest.

Arizona-Specific Considerations

Arizona has some unique auto loan regulations that affect your payments:

• Interest rates are typically higher than the national average
• Loan terms are often longer than the standard 4 years
• Some lenders offer special programs for first-time buyers
• Title and registration fees are additional costs

The calculator accounts for these factors by using Arizona's average interest rates and including common additional fees in the total cost estimate.
