How Extra Payments Work

Making extra payments on your auto loan can significantly reduce the total interest you pay and pay off your loan faster. Here's how it works:

Interest Reduction: Extra payments go directly toward the principal balance, reducing the amount of interest that accumulates over time.
Faster Payoff: By paying more than the minimum each month, you'll eliminate your loan balance in fewer months.
Lower Total Cost: The sooner you pay off your loan, the less interest you'll pay over the life of the loan.

Formula Used

The calculator uses the following formula to determine the loan payoff details:

Calculate the monthly interest rate: monthlyRate = annualRate / 12
Calculate the total number of payments: totalPayments = loanTerm * 12
Calculate the monthly payment with extra payments: monthlyPayment = (loanBalance * monthlyRate) / (1 - (1 + monthlyRate) ** -totalPayments) + extraPayment
Calculate the total interest paid: totalInterest = (totalPayments * monthlyPayment) - loanBalance
Calculate the total savings: totalSavings = originalTotalInterest - totalInterest

Worked Example

Let's look at an example to see how extra payments can affect your auto loan payoff.

Suppose you have a $20,000 auto loan with a 5% annual interest rate and a 5-year term. Your regular monthly payment is $350. If you make an extra payment of $200 each month:

Your new monthly payment will be $550 ($350 + $200).
You'll pay off your loan in about 4 years and 2 months instead of 5 years.
You'll save approximately $1,200 in interest over the life of the loan.

This example shows how making extra payments can significantly reduce your loan term and interest costs.
