The very first thing is to stay calm and take action right away. Ignoring the missed payment will only make things worse. Log into your account online or call the company you owe money to. Tell them you missed the payment. They might be able to help you, and it shows you are trying to fix the problem. The sooner you deal with it, the better your chances of avoiding extra fees or a big hit to your credit score.

Pay your full statement balance by the due date every single month. If you do this, you won’t be charged any interest at all. Think of it as a free loan for a few weeks! The key is to only buy things you already have the money for in your bank account. This simple habit is the number one rule for using credit cards wisely and keeping your money in your pocket.

You should check it at least once a year. A great plan is to get one free report every four months, rotating between the three companies. This way, you can keep an eye on things all year long for free. Also, check it about three to six months before you plan to apply for a big loan, like for a car or house. This gives you plenty of time to fix any problems you find.

Yes, using too much of your available credit limit hurts your score. Even if you pay the bill in full every month, a high balance when the card company reports it makes you look risky. Try to keep what you owe on each card below 30% of its limit. For example, on a $1,000 limit card, try to keep your balance under $300 when your statement comes.
