Auto Loan Calculator Mortgage

This auto loan calculator helps you determine your monthly car loan payments, total interest paid, and loan payoff date based on the loan amount, interest rate, and loan term you choose. Whether you're buying a new or used car, this tool provides a clear picture of your financing obligations.

How to Use This Calculator

Using our auto loan calculator is simple. Follow these steps:

Enter the loan amount - the total price of the car you're financing.
Input the interest rate - the annual percentage rate (APR) offered by your lender.
Select the loan term - the length of your loan in years.
Click the Calculate button to see your monthly payment, total interest, and payoff date.

The calculator will display your monthly payment, total interest paid over the life of the loan, and the date you'll pay off the loan. You can also see a chart showing the breakdown of principal and interest payments over time.

Formula Explained

The auto loan calculator uses the standard mortgage formula to calculate your monthly payments:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount i = Monthly interest rate (annual rate divided by 12) n = Number of payments (loan term in years multiplied by 12)

This formula accounts for the fact that each payment includes both principal and interest, with the interest portion decreasing over time as the principal balance decreases.

Note

This calculator assumes a fixed interest rate and does not account for prepayment penalties, tax deductions, or other fees that might affect your actual payments.

Worked Example

Let's look at an example to see how the calculator works. Suppose you're financing a car with these details:

Loan amount: $25,000
Interest rate: 4.5% APR
Loan term: 5 years

Using the formula:

M = $25,000 [ (0.045/12)(1 + 0.045/12)^60 ] / [ (1 + 0.045/12)^60 - 1 ] M ≈ $452.34

So your monthly payment would be approximately $452.34. Over the 5-year term, you would pay a total of $12,678.20 in interest, and your loan would be paid off in December 2028 if you started in January 2023.

Payment	Principal	Interest	Balance
1	$375.18	$77.16	$24,624.82
2	$377.66	$74.68	$24,247.16
3	$380.15	$72.19	$23,866.99

60	$452.34	$0.00	$0.00

Frequently Asked Questions

How accurate is this auto loan calculator?

This calculator provides an estimate based on standard mortgage formulas. For precise figures, consult with your lender who can account for additional fees and specific terms.

Does this calculator account for down payments?

No, this calculator only considers the loan amount. You should subtract your down payment from the total car price before entering the loan amount.

Can I use this for leases instead of loans?

This calculator is designed for auto loans only. For lease calculations, you would need a different tool that accounts for monthly payments that include depreciation.

What if my interest rate changes during the loan term?

This calculator assumes a fixed interest rate. If your rate changes, you would need to recalculate your payments or consult with your lender.
