Credit cards can be convenient tools that cost nothing, provide purchasing discounts, and boost a credit score. However, they can also lead to racking up debt, paying extra for every purchase, and diminishing a credit score. Like all tools, credit cards can help us build or destroy.

Understanding the following three things is the first step toward using credit cards effectively.

1. Cost: Most credit cards come with a grace period, during which interest on purchases does not accrue. If you pay your balance in full each billing cycle, you will not be charged any interest. Using a card this way means you pay nothing for the convenience and may also accrue points that can discount future purchases.

However, if you leave even a small balance on the credit card, the grace period is eliminated. Until the balance is paid, you will accrue interest on both new and existing charges.

2. Utilization Ratio: If you pay balances in full but regularly use greater than 30% of your credit limits your credit score will be reduced. Maxing out credit cards is a sure way to lower your credit score. Credit reports will show your credit card limits, current balances, and the maximum amount utilized. The utilization ratio has a significant impact on your credit score.

3. Impact on Money Decisions: Credit cards can make buying easy and controlling spending hard. Companies lure us in with promises of rewards and fun. If you tend to spend first and think about it later, avoid using credit cards as the go-to means of paying. Consider other options that allow you to take a minute and evaluate your financial big picture.
