Responsible use of credit cards is a very useful financial tool. Consistent on-time payments can increase your credit rating, some credit cards offer purchase rewards, and even offer a 0% interest rate on balances transferred from other credit cards in the short term.

But if your credit spending goes out of control, monthly payments and accrued interest rates can become a problem. Please follow the credit card tips below to help avoid common problems:

Pay your balance every month.

Avoid paying your credit card purchase interest by paying the full balance for each billing cycle. 1 Resist the temptation to spend more than any month you can pay, and you will enjoy the benefits of using a credit card without charging interest.

Use this card to meet your needs, not to meet your needs.

Credit cards should be used with caution. A frivolous purchase can lead to debt. Credit cards can be used in an emergency, such as a mobile bill that expires on the next payday. Use a credit card as a temporary loan to yourself and then repay the amount as soon as possible to reduce or avoid interest charges.

Don't miss the payment.

Pay your bills monthly, even if the minimum payment is what you can afford. Missing payments can result in late fees, fine rates, and negative impact on your credit score.

Use a credit card as a budget tool.

If you are confident, you can use your credit card responsibly, pay off your balance every month, and try to use it as a budget tool. By shopping with a credit card, you can clearly see how much you spent at the end of the month. Of course, you should only do this if you know that you can pay the balance every month. To make sure your credit card spending doesn't get out of hand, don't charge your credit card more than you do in your bank account.

Use a reward card.

If you use a credit card for most or all of your spending, it makes sense to use a credit card that provides rewards. Not only can you avoid paying interest, you can also get rewards such as cash, airline miles or retail points.

Less than 30% of the total credit limit.

One way to keep your credit score healthy is to keep your credit utilization below 30%. This credit utilization is the percentage of total available credit that you use. For example, if your limit is $1,000, you should keep your balance below $300. But this ratio applies to the sum of all credit cards - so if one credit card has a balance of $3,000 and another credit card has a balance of $7,000 without a balance, you are at exactly 30% (available $3,000 out of $10,000).
