Avoid Ruining Your Credit [Infographic] Your credit score is one of the most important financial tools you should maintain. A poor credit score tells lenders that you may not have good money management skills. On the other hand, a good score says you are a trustworthy borrower. People with good credit scores have an easier time qualifying for business and personal loans, mortgages and credit cards.Sometimes, maintaining a good credit score is easier said than done. There are plenty of incidents that can bring that crucial three-digit number down. Missing a payment can lower your score by as many as 100 points.Pay your billsYou might usually be proactive about paying your bills on time, but missing just one can have some serious consequences on your score. Your payment history is the most important factor in calculating that number - it accounts for 35 percent of it. To avoid missing any payments, consider setting up automatic payments or creating a reminder of when bills are due.Don't load up on cardsWhile it's good to have some lines of credit open to build your credit history, your score is negatively affected every time you shop for a new one. When you apply for another credit card, your score could drop by as much as 10 percent. Avoid this by being sure not to open too many cards in a short period of time.Avoid the dangers of co-signingYour friend or relative might be in a tough spot and ask you to co-sign a loan. It can be difficult to say no to someone you care about, but it might be the best option for you. When you put your name on someone else's loan, you are just as liable as the other person. If he or she begins to fall behind on payments, it will jeopardize your good credit.Having a good credit score is crucial if you want to get a larger loan some day. Because of this, it's important to be smart about how you use the credit you have now. The information provided in these articles is intended for informational purposes only.
