Good credit saves you money. For example, having good credit can get you a better interest rates on credit cards.
Credit card companies offer lower interest rates to their best customers, sometimes in the single digits.
The catch: Most of the time you have to ask for the lower rate. So if you're a good customer and you're paying 15 percent on your credit card, try calling the company for a lower rate. On a $5,000 balance, you would pay about $119 monthly at 15 percent. At 9 percent, you'd pay $104, a $15 monthly savings.
