Savings bonds are the single most common investments that young adults have.
They are usually given to us as gifts. What they are are basically notes in the form of money from the government that say that they owe you the amount of the savings bond. However, they do not owe you that much money for 30 years. The reason that you get more than you paid for is because bonds earn interest . What this means is that for every dollar that you loan the government, they pay you back that much and a little more.
