Investments which have a fixed or variable rate of interest are one
of the simplest and most common form of investments available. Interest
bearing investments include your bank account, a certificate of deposit,
or any other kind of investment in which you receive interest from the
principal. This section will describe how to handle these kinds of
When you purchase the interest bearing investment, you must create an asset account to record the purchase of the investment, an income account to record earnings from interest, and an expense account to record bank charges. Below is an account layout example, in which you have an interest bearing savings account and a certificate of deposit at your bank.
As usual, this account hierarchy is simply presented as an example, you should create your accounts in a form which best matches your actual situation.
Now let’s populate these accounts with real numbers. Let’s assume that you start with $10000 in your bank account, which pays 1% interest and you buy a $5000 certificate of deposit with a 6 month maturity date and a 2% yield. Clearly, it is much better to keep your money in the CD than in the savings account. After the initial purchase, your accounts should look something like this:
Now, during the course of the next 6 month, you receive monthly bank statements which describe the activity of your account. In our fictional example, we do nothing with the money at this bank, so the only activity is income from interest and bank charges. The monthly bank charges are $2. After 6 months, the register window for the CD should look like this:
And this is the main
From the above image of the main
GnuCash account window you see a
nice summary of what happened to these investments over the 6 months.
While the yield on the CD is double that of the savings account, the
return on the CD was $50.21 versus $13.03 for the savings account, or
almost 4 times more. Why? Because of the pesky $2 bank charges that hit
the savings account (which counted for $12 over 6 months).
After this 6 month period, the CD has reached maturity which means you may sell it with no early withdrawal penalty. To do so, simply transfer the $5050.21 from the CD account into the savings account.
