How to Use This Calculator

To use this refinance auto calculator, follow these simple steps:

Enter your current auto loan balance in the "Current Loan Balance" field.
Enter your current monthly payment in the "Current Monthly Payment" field.
Enter your current interest rate in the "Current Interest Rate" field.
Enter the new interest rate you're considering in the "New Interest Rate" field.

The calculator will display your potential monthly payment, total interest paid, and total cost of the loan with the new terms. It will also show you the amount you could save by refinancing.

Formula Used

The refinance auto calculator uses the following formula to calculate your new monthly payment:

Monthly Payment Formula

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

Where:

P = Principal loan amount (current loan balance)
r = Monthly interest rate (new interest rate / 12)
n = Number of payments (new loan term in years * 12)

The calculator then calculates the total interest paid and total cost of the loan by multiplying the monthly payment by the number of payments and subtracting the principal loan amount.

Worked Example

Let's say you have a current auto loan balance of $20,000 with a current monthly payment of $350 at an interest rate of 6%. You're considering refinancing to a new interest rate of 4% over a 5-year term.

Using the formula:

Example Calculation

Monthly Payment = $20,000 * (0.04/12 * (1 + 0.04/12)^60) / ((1 + 0.04/12)^60 - 1)

Monthly Payment ≈ $288.50

Total Interest Paid = ($288.50 * 60) - $20,000 = $1,710

Total Cost of Loan = $20,000 + $1,710 = $21,710

Potential Savings = ($350 * 60) - ($288.50 * 60) = $378

By refinancing, you could save $378 over the life of the loan and pay $288.50 per month instead of $350.

When to Refinance Your Auto Loan

Refinancing your auto loan can be a good idea if you can secure a lower interest rate than what you're currently paying. Here are some situations where refinancing might make sense:

You have good credit and can qualify for a lower interest rate.
You're planning to keep your car for a long time and want to lock in a lower rate.
You've paid down a significant portion of your loan and want to reduce your monthly payment.
You're considering trading in your car and want to minimize the cost of the new loan.

However, there are also situations where refinancing might not be a good idea:

You're in a short-term financial situation and need to keep your monthly payment low.
You're planning to sell or trade in your car soon and want to avoid the costs of refinancing.
You're not sure you can qualify for a better rate and might end up paying more in the long run.

Before refinancing, make sure to compare the costs and benefits carefully and consider getting quotes from multiple lenders.
