How To Earn 3.5% Interest On US Savings Bonds!

Buy an EE Series US Saving Bond
This sounds too good to be true. You must be thinking “What’s the catch?”

There is one catch, and its a big one:

You cannot redeem the savings bond until maturity (which is 20 years after the bond is issued). If you need to cash-in the bond, you will earn a measly 0.6% minus any early withdrawal penalties.

That is the only catch but there is one other limitation.

The maximum amount of EE bonds a person can purchase is $10,000 per year.

This 3.5% interest rate is not a temporary teaser rate or subject to change. However, you will not see this rate advertised anywhere on the Treasury Department website.

You will see the following statement:

At a minimum, the U.S. Treasury guarantees that an EE Bond’s value will double after 20 years, its original maturity, and it will continue to earn the fixed rate unless a new rate or rate structure is announced. If a bond does not double in value as the result of applying the fixed rate for 20 years, the U.S. Treasury will make a one-time adjustment at original maturity to make up the difference. Series EE bonds earn interest for 30 years.

When I read this statement, I thought it was odd. At the time that this article was researched (11/1/2011)  the interest rate on the EE series savings bond was 0.6%. There was no way that an interest rate of 0.6% could lead to doubling of the value of a bond in 20 years. Then, I made use of the rule of 72 to figure out how long it would take for a bond to double in value. The rule of 72 states that if you take the number 72 and divide it by the interest rate you get the number of years it will take for your money to double.

For anything earning less than 1%, it would take more than 72 years to double your money.  As this is the case, the effective interest rate on EE Series savings bonds had to a lot more than 0.60%. Using semi-annual compounding over 20 years, a $1000 bond will become $2001.60 (double in value) with an interest rate of of 3.5%.

How good is a 3.5% interest rate?

At the time this article was written (11/1/2011) that is about 1% higher than the rate a 20 Year Treasury bond is paying.  This is pretty good considering that you are getting about 33% more interest for the same level of risk.

    “At the time this article was written that is about 1% higher than the rate a 20 Year Treasury bond is paying.” ………Not being a finance guru, it would be helpful to know date article was written; otherwise great info to be aware of.

    Also would appreciate seeing similar article on the Series I Bonds – dated of course.

    I want to start a college fund for my infant grandson. I am thinking I bond in his name and his dads name. Is this a good idea.??

      Hi Dottie. Thank you for your comment. Since I am not a financial advisor I cannot comment on your specific situation however in general I do think that i Bonds are currently a good investment. Assuming that the child’s education is going to be paid for by the parents (they are the ones who are going to be writing the checks) then you do not want to list the child as co-owner of the bond. The reason why is that in many cases if a savings bond is used to pay for Education then the income from the bond is tax free, as long as the bond is owned by the person who is paying for the education. Listing the child as beneficiary of the bond is fine but they cannot be listed as the co-owner of the bond.
