Credit cards are an essential tool to manage finances for many people and for small business funding, and when used correctly they can make purchasing goods safer and easier, especially online. Also, taking advantage of the bonus points, rewards and cash back they offer can even provide greater spending power. However, many people also dread the arrival of their monthly credit card statements because they have overspent, or because they are paying too high of an interest rate.

In this case, you should try to boost your credit rating to lower the interest rate when you apply for new cards. If you've had a credit card for years and never missed a payment it can be worth shopping around for a card with a better interest rate. Another tip is to always pay back more than the minimum amount, because paying only the minimum means that it takes forever to pay off the balance and you end up spending much more in interest costs.
