The calculator will display your monthly payment, total interest paid over the loan term, and a chart showing the amortization schedule.

Note: This calculator assumes monthly payments and does not account for prepayment penalties or other fees that might apply to your specific loan.

Formula Used

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

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

Where:

P = Principal loan amount (loan amount - down payment)
r = Monthly interest rate (annual rate / 12 / 100)
n = Number of payments (84 months)

Total interest paid is calculated by subtracting the principal from the total amount paid over the loan term.

Worked Example

Let's calculate a 7-year auto loan with these parameters:

Loan amount: $30,000
Interest rate: 5% annual
Down payment: $3,000

Principal = $30,000 - $3,000 = $27,000

Monthly interest rate = 5% / 12 = 0.4167%

Using the formula:

Monthly Payment = $27,000 × (0.004167(1 + 0.004167)^84) / ((1 + 0.004167)^84 - 1)

Monthly Payment ≈ $392.45

Total amount paid over 7 years = $392.45 × 84 = $33,091.60

Total interest paid = $33,091.60 - $27,000 = $6,091.60

Loan Amount	Interest Rate	Down Payment	Monthly Payment	Total Interest
$30,000	5%	$3,000	$392.45	$6,091.60

Frequently Asked Questions

What is a 7-year auto loan?

A 7-year auto loan is a car financing option that spreads payments over 84 months (7 years) at a fixed interest rate. It typically offers lower monthly payments than shorter-term loans but results in paying more in total interest.

How does the interest rate affect my monthly payment?

A higher interest rate will increase your monthly payment and the total amount paid over the life of the loan. Conversely, a lower interest rate will reduce both your monthly payment and total interest paid.

What is the difference between APR and interest rate?

The interest rate is the cost of borrowing expressed as a percentage, while APR (Annual Percentage Rate) includes additional fees and costs associated with the loan. APR is always equal to or higher than the interest rate.

Can I pay off my auto loan early?

Yes, you can pay off your auto loan early, but check your loan agreement for any prepayment penalties. Some loans have clauses that require you to pay a fee if you pay off the loan before a certain period.
