Average APY. According to CNN Money, the average annual percentage yield on a savings account in the United States was just 0.06 percent in 2013. This means that if you nested away $100,000 in the average savings account, it would net you an additional $60 in interest over the course of one year.
A $10,000, one-year certificate of deposit with a stated annual interest rate of 10% will earn $1,000 at maturity. If the money was placed in an interest-earning savings account that paid 10% compounded monthly, the account will earn interest at a rate of 0.833% each month (10% divided by 12 months; 10/12 = 0.833).
