Develop a Good Credit Score
Great credit begins with making your payments on time. A payment late just 30 days could be reported to a collections agency. A collection on your credit report will stay there for at least seven years, even if you’ve paid the debt with the collection agency. This is the quickest way to lower your credit score and make it difficult or impossible to obtain future credit.
Just as it is important to pay bills on time, paying down your debts in full is almost just as important. This especially applies to credit cards, also known as “revolving credit”. Aim to never spend more than 35% of your available credit limit - even if you have the funds available to pay back more. Example: if you have a $1000 credit limit, never spend more than $350 at a time - even if you have $1000 to pay the charges back. This demonstrates responsible credit management by always have more available than you’ve spent.
Do not save what is left after spending, but spend what is left after saving."
