This Arizona Federal Credit Union Auto Loan Calculator helps you estimate your monthly payments, total interest, and loan cost before applying for an auto loan. Simply enter your loan amount, interest rate, and loan term to get an instant estimate.

How to Use This Calculator

Using this calculator is simple:

Enter the loan amount you're considering (e.g., $20,000)
Input the interest rate offered by Arizona Federal Credit Union (typically between 4% and 8%)
Select the loan term in years (common options are 3, 4, 5, or 6 years)

The calculator uses the standard auto loan payment formula to provide accurate estimates. Remember that actual loan terms may vary based on your creditworthiness and the credit union's specific requirements.

Formula Used

The auto loan payment is calculated using the standard loan payment formula:

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

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

Total interest is calculated by subtracting the original loan amount from the total amount paid over the life of the loan.

Worked Example

Let's calculate an example auto loan:

Loan amount: $25,000
Interest rate: 6.5% APR
Loan term: 5 years

Using the formula:

Monthly interest rate = 6.5% ÷ 12 = 0.5417%

Number of payments = 5 × 12 = 60

Monthly payment = $25,000 × (0.005417 × (1 + 0.005417)^60) / ((1 + 0.005417)^60 - 1)

Monthly payment ≈ $472.36

Total amount paid = $472.36 × 60 ≈ $28,341.60

Total interest = $28,341.60 - $25,000 = $3,341.60

This example shows that a $25,000 loan at 6.5% APR over 5 years would have a monthly payment of approximately $472.36, with a total interest cost of about $3,341.60.

Frequently Asked Questions

What is the difference between APR and interest rate?: The Annual Percentage Rate (APR) is the total cost of credit, including any fees, while the interest rate is the cost of borrowing without fees. APR is always higher than the interest rate.
How does my credit score affect my auto loan?: Your credit score determines your interest rate and loan terms. Higher credit scores typically qualify for lower rates and better terms. Arizona Federal Credit Union may offer better rates to members with good credit.
What fees should I expect with an auto loan?: Common fees include origination fees (1-5% of loan amount), application fees, and prepayment penalties. These can vary by credit union and loan terms.
Can I pay off my auto loan early?: Yes, you can pay off your loan early, but check for prepayment penalties. Some loans have a prepayment penalty period (typically 3-6 months).
