Formula Used

The monthly payment (P) is calculated using the standard auto loan formula:

P = [r + r / ((1 + r)^n - 1)] × L

Where:

r = monthly interest rate (annual rate ÷ 12)
n = number of payments (loan term × 12)
L = loan amount (purchase price - down payment)

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

Worked Example

Let's calculate payments for a $30,000 loan with a 10% down payment, 5-year term, and 4.5% interest rate:

Loan amount = $30,000 - ($30,000 × 10%) = $27,000
Monthly interest rate = 4.5% ÷ 12 = 0.375%
Number of payments = 5 × 12 = 60
Monthly payment = [$27,000 × 0.00375 × (1 + 0.00375)^60] ÷ [(1 + 0.00375)^60 - 1] ≈ $478.50
Total payments = $478.50 × 60 = $28,710
Total interest = $28,710 - $27,000 = $1,710

This example shows you would pay approximately $478.50 per month with $1,710 in total interest over 5 years.

Frequently Asked Questions

What factors affect my auto loan interest rate?: Capital One's interest rates are primarily based on your credit score, loan term, and down payment. Other factors may include your employment history and the type of vehicle you're financing.
How does a larger down payment affect my loan?: A larger down payment reduces your loan amount and can lower your interest rate. It also decreases your monthly payments and total interest paid over the life of the loan.
What is the difference between APR and interest rate?: APR (Annual Percentage Rate) includes all fees and costs associated with the loan, while the interest rate is the cost of borrowing. APR is typically higher than the interest rate because it includes additional fees.
Can I pay off my auto loan early without penalties?: Capital One typically allows prepayment without penalty, but you should check your loan agreement for specific terms. Paying off early can save you money on interest.
What documents do I need to apply for an auto loan?: You'll typically need proof of income, identification, and vehicle information. Capital One may also require a credit check and vehicle appraisal.
