Auto Loan Calculator Secu

This auto loan calculator helps you estimate your monthly payments, total interest paid, and loan amortization schedule when financing a vehicle through SECU. Simply enter your loan amount, interest rate, and loan term to get accurate results.

How to Use This Calculator

Using the auto loan calculator is simple:

Enter the loan amount you're requesting from SECU
Input the annual interest rate (APR) offered by SECU
Select the loan term in years
Click "Calculate" to see your monthly payment and other details

The calculator will display your estimated monthly payment, total interest paid over the life of the loan, and an amortization schedule showing how your loan balance decreases each month.

Formula Used

The auto loan calculator uses 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)

This formula calculates the fixed monthly payment required to pay off the loan over the specified term.

Worked Example

Let's calculate a loan with these parameters:

Loan amount: $25,000
Annual interest rate: 5.5%
Loan term: 5 years

Using the formula:

Monthly interest rate = 5.5% ÷ 12 = 0.004583

Number of payments = 5 × 12 = 60

Monthly Payment = $25,000 × (0.004583(1 + 0.004583)^60) / ((1 + 0.004583)^60 - 1)

Monthly Payment ≈ $467.50

Total interest paid over 5 years would be approximately $3,420.

Frequently Asked Questions

What is the difference between APR and interest rate?

The Annual Percentage Rate (APR) is the total cost of credit, including fees and interest, expressed as a yearly rate. The interest rate is the actual borrowing cost without additional fees.

How does loan term affect my monthly payment?

A longer loan term means lower monthly payments but more total interest paid. A shorter term results in higher monthly payments but less total interest.

Can I pay extra toward my loan without penalty?

Yes, most auto loans allow prepayment without penalty. Paying extra can reduce your total interest and pay off the loan faster.
