A high credit score is more than a number to impress your golfing buddies or people at your office Christmas party. While you can brag about having an 800+ credit score to show off your financial acuity, a good credit rating does have a practical purpose.
Lenders use your credit score to determine how responsible you are with money and whether you will pay your bills on time. An outstanding score means you can get the lowest interest rates on credit cards, auto loans, mortgages, or business loans. It could even get you better rates on your car insurance.
