How to use this calculator

This calculator helps you see the impact of making extra payments on your auto loan. Here's what you need to know:

1

Current Loan Balance

Enter your current remaining loan balance. You can find this on your most recent loan statement or by calling your lender.

2

Loan Terms

Enter your current interest rate (APR) and remaining loan term in months. These determine how much interest you're paying.

3

Extra Payment Amount

Decide how much extra you can afford to pay each month. Even small amounts like $25 or $50 can make a significant difference over time.

Benefits of extra payments

Pay off your loan faster

Extra payments go directly toward your principal balance, reducing the amount of interest you pay over the life of the loan.

Save money on interest

By reducing your principal faster, you'll pay less interest overall, potentially saving hundreds or thousands of dollars.

Build equity faster

Faster payoff means you'll own your vehicle outright sooner, giving you more financial flexibility.

Extra payment strategies

Consistent extra payments

Adding a fixed amount to each monthly payment is the most effective strategy. Even $25 extra per month can save significant interest.

Lump sum payments

Use tax refunds, bonuses, or other windfalls to make larger one-time payments toward your principal.

Bi-weekly payments

Instead of monthly payments, make half-payments every two weeks. This results in 26 half-payments per year (equivalent to 13 full payments).

Things to consider

Prepayment penalties

Most auto loans don't have prepayment penalties, but it's always good to check your loan agreement before making extra payments.

Emergency fund priority

Make sure you have an emergency fund before making extra loan payments. Financial security should come first.

Higher interest debt

If you have credit card debt or other loans with higher interest rates, pay those off first before making extra auto loan payments.
