Series EE Bonds and Series I Bonds are the two types of savings bonds that are offered by the treasury. Series EE bonds can either be electronic or paper based. Electronic EE bonds can be directly purchased from. An electronic EE bond is sold at the face value, which means that if you buy a $50 bond for $50, the bond is worth the full amount when you redeem it. This is not so in the case of a paper EE bond, which is sold at half its value, that is, you would have to shell out $50 to purchase a $25 bond. Plus, a paper EE bond reaches the face value only when it matures as it increases in value over time with accruing interest. On both these EE bonds, the maximum limit that can be purchased in a year is $5000.
Series I Bonds are quite similar to their counterparts the EE Bonds, but with a crucial difference. The “I” in the name denotes inflation, and they are named so because the interest rate in the case of these bonds is indexed to the inflation rate. A fixed rate is set initially for the bond which continues till maturity, plus an inflation rate on top of that is determined bi-annually. Series I Bonds can also be bought as electronic or paper bonds and both forms are sold at face value unlike EE bonds. They also have a maximum purchase limit of $5000 per calendar year.
Both types of Savings Bonds are a safe bet, but for a depositor looking for the better of the two, I Bonds have performed better than EE Bonds over the long term due to the rising rates of inflation.
