Albert Einstein reportedly called it the 8th wonder of the world, saying He who understands it, earns it; he who doesn't pays it.Einstein knew that compound interest is a force to be reckoned with. Today, financial planner and teacher Rob West explains how you can either make it work for you or let it work against you. Then it’s your calls at 800-525-7000.

A recent financial literacy survey found that individuals who fail to grasp the concept of interest that compounds have higher transaction fees, run up more debt, and pay higher interest rates on credit cards and other loans.Simple interest is what you pay on the original amount you borrowed or what you have in the bank only.Simple interest applies a fixed rate, meaning that the dollar amount you pay in interest remains the same for the life of the loan or account.Compound interest is calculated on your principal amount, plus your accumulated interest. So the amount you pay, or receive, in interest will change, it will grow over time.Compound interest works for you if you’re saving money, but against you if you’re borrowing.To take advantage of compound interest,do not carry a balance on your credit card. Pay off any consumer loans as quickly as possible, making additional payments on the principal if you can.
