It’s a simple guideline to keep your score safe. Try not to let your balance go above 30% of your credit card’s limit. For example, if your limit is $1,000, aim to keep your balance below $300. This isn’t a strict law, but staying below this mark tells the credit bureaus you’re not overusing your card. Remember, lower is even better! The people with the very best scores often keep their utilization below 10%.

Try to use less than 30% of your total credit limit. For example, if you have a card with a $1,000 limit, aim to keep your balance below $300 when the statement is created. This is called your “credit utilization,“ and a low number shows you’re responsible and not maxed out. It’s even better to pay off the full balance each month to avoid interest charges. High balances can make you look risky to lenders, even if you pay on time.

Start by getting your credit reports for free. You can get them at AnnualCreditReport.com. Look at them very carefully. Check for mistakes like wrong addresses, accounts you never opened, or late payments you know you paid on time. Finding these errors is step one. If you see a mistake, you can dispute it to get it removed. This can sometimes give your credit score a quick boost.

A credit card is a tool that lets you borrow money to buy things, with a promise to pay it back later. You need one to build a “credit history,“ which is like a report card for how you handle money. A good history helps you later for big goals, like renting an apartment or getting a car loan. Think of it as practice for bigger financial responsibilities. Using a card wisely shows banks you can be trusted.
