Savings accounts typically earn compound interest. Whenever interest is calculated, it is based not only on the original amount in the account but also on any interest that has been added. The more frequently interest is compounded, the faster the balance grows. The rate that interest is compounded is referred to as the Annual Percentage Yield (APY).
Simple interest is based only on the original amount deposited into an account. If your account has $100 in it and earns 5%1 simple interest per year, it earns $5 interest. Multiply the dollar amount by the interest rate to get the return. Although extremely rare, you may come across simple interest as you grow older and your investments diversify.
The Rule of 72 can give you an approximation of how long it will take to double your money at a specified interest rate. If you’re earning 6%1 interest, divide 72 by 6. That means it will take about 12 years for your original investment to double in value at a 6%1 interest rate.
The federal government allows you to make up to six electronic transfers, using Online Banking or Telephone Banking, during a monthly statement cycle from a savings account. If this limit is exceeded, you may be assessed a fee for each transaction in excess of the limits. However, you can make unlimited transfers at any Chevy Chase Bank branch or ATM.
