Investing in savings bonds 

When investing in savings bonds, you need to understand the following terms and how to find them.

  • Face value 
  • Cost of the savings bonds
  • Redemption value
  • Interest earned

Keep in mind that savings bonds are usually sold by the United States government. You just need to pay 50% of the face value.

The face value is the original price of the savings bonds. Saving bonds can be purchased with a face value ranging from 50 to 10,000.

The cost of the saving bonds is 50% of the face value.

The redemption value is the value of the bond when it is redeemed. This is usually based on how long you invest and how much the government is willing to pay. See redemption table below. You will need to find the redemption value before you can compute the interest you will earn. The face value is used when computing the redemption value.

Redemption value of 100 dollars

The way we compute the interest earned when investing in savings bonds is different than the way we compute interest in bonds. In order to find out how much interest you will earn, you need to subtract the cost of the savings bonds from the redemption value.

Interest earned = redemption value − cost of savings bonds

A couple of examples showing how investing in savings bonds work

A chart similar to the one above could be used when computing the redemption value.

Example #1

Say for instance, you buy a 1000 dollars bond and redeemed it 4 years later. Using the redemption table shown above, find the redemption value of the bond and the amount of interest you will earn.

Here is how you can compute the redemption value:

Redemption value = (redemption value of 100 dollars after 4 years) × (number of 100 dollars in face value).

Since 1000/100 = 10, the number of 100 dollars in face value is 10. 

60.21 × 10 = 602.1

The redemption value is 602.1 dollars

Cost of savings bonds  = face value × 50%

Cost of savings bonds = 1000 × 0.50

Cost of savings bonds = 500

Interest earned = redemption value − cost of savings bonds

Interest earned = 602.1 - 500

Interest earned = 102.1

The interest earned is 102.1 dollars

Example #2

Say for instance, you buy savings bonds in the amount of 3 million dollars and redeemed it 5 years later. Using the redemption table shown above, find the redemption value of the bond and the amount of interest you will earn.

Here is how you can compute the redemption value:

Redemption value = (redemption value of 100 dollars after 5 years) × (number of 100 dollars in face value).

Since 3000000/100 = 30000, the number of 100 dollars in face value is 30000

62.50 × 30000 = 1875000

The redemption value is 1875000 dollars

Cost of savings bonds  = face value × 50%

Cost of savings bonds = 3000000 × 0.50

Cost of savings bonds = 1500000

Interest earned = redemption value − cost of savings bonds

Interest earned = 1875000 - 1500000

Interest earned = 375000

The interest earned is 375000 dollars
