How Auto Refinancing Works

Auto refinancing involves replacing your current auto loan with a new loan from a different lender. This can be done for several reasons:

To secure a lower interest rate
To shorten the loan term
To switch from an adjustable-rate mortgage to a fixed-rate mortgage
To consolidate multiple auto loans into one

The process typically involves:

Applying for a new auto loan
Paying off your current loan
Receiving the new loan funds

It's important to consider the costs and benefits of refinancing, including closing costs, fees, and potential impact on your credit score.

Formula Used

The calculator uses the standard auto loan payment formula:

Auto Loan 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 (annual rate divided by 12)
n = Number of payments (loan term in months)

The calculator compares this formula with your current loan terms and the new loan terms you enter to provide an estimate of your new monthly payment.

Worked Example

Let's say you have a current auto loan with these terms:

Current loan balance: $25,000
Current interest rate: 6.5% APR
Remaining loan term: 48 months

You're considering refinancing with these new terms:

New interest rate: 4.5% APR
New loan term: 60 months

Using the calculator:

Enter $25,000 as the current loan balance
Enter 6.5 as the current interest rate
Enter 48 as the remaining loan term
Enter 4.5 as the new interest rate
Enter 60 as the new loan term
Click "Calculate"

The calculator will show that your estimated new monthly payment would be approximately $425.67, compared to your current estimated payment of $541.67. This represents a savings of about $116 per month.
