Your credit score is one of the biggest deciding factors in your financial health. It influences whether you qualify for the best interest rates on mortgages or auto loans, it can impact your insurance rates, and it can even determine whether you land that dream job or not.
Establishing good credit requires managing your credit accounts responsibly. But your own credit score isn’t the only one that can suffer the consequences of poor credit management. In the same way money can ruin a friendship, your financial carelessness could ruin someone else’s credit. Here’s how.

Becoming an authorized user on someone else’s credit card helps build your own credit history. You’ll receive a credit card in your name, and you’re allowed to make charges on the account. But even though your name is on the card and the account shows up on your credit report, only the primary account holder receives the statements. This person is ultimately responsible for any purchases you make with the card.
If you’re an authorized user, the mature thing to do is pay whatever you charge each month. If you don’t or can’t pay, this sets in motion a chain of events that could ruin the other person’s credit.
Any purchases you charge to the account can raise the primary account holder’s balance and increase their credit utilization ratio beyond a healthy range (utilization ratio is the credit card balance compared to the credit limit).

In addition, ringing up charges on someone’s credit card and not paying what you owe could trigger payment problems. This can happen if the primary user doesn’t have enough money for higher minimum payments. If they can’t pay the credit card bill within 30 days, the credit card company could report the late payment to the credit bureaus. While a 30-day delinquency won’t tank a credit…
