Both of your friends are correct—ultimately, it comes down to a person’s financial situation. Paying off a car loan early can hurt your credit temporarily, but it can also help if you have a high debt-to-income ratio.
On the other hand, if you have a high debt-to-income ratio, paying off your car loan could help improve your credit score. By paying off your loan, you’d reduce the amount of debt you have, which will lower your debt-to-income ratio. When you successfully pay off a loan, lenders also consider you a lower risk as you’re less likely to default on a loan in the future.
Before you decide whether to pay off your car loan, consider using a credit score calculator. Some companies or credit services allow you to estimate how making changes to your credit would impact your score.
